    Hanging Gear Clock

    I can see merit in adjusting the gear count to 30 and 60, then doing the movements in surges. e.g. it stays at 12 until it's time to move it all the way to 1:00. This would make the clock easier to read.I think I would make the minute gear have dots between the 0 and 15 etc like the hour gear does.

    Don't think a magnet and reed switch will be precise enough. The magnetic field will slowly get stronger as it approaches. How does a CNS milling machine reset it's position? Lots of x-y plotters do it by deliberately going to one end of the travel, until the stepper motor stalls. That doesn't work here. You need something with a very abrubt signal edge. How about a piece of flat black paper on the back of the gear, with a columnated LED and photocell?Or a thumbtack, and a pair of wire whiskers. Program a constant for it's offset.Most of the time corrections are going to be tiny. If the clock is fast, the controller just misses N steps until the world catches up. If slow, it adds enough steps to bring it to right time.

    Quick-Release Bandsaw Fence

    If you are resawing wood:* You need a wide blade. 3/4inch minimum. 1.25" is better.* You need serious tension on the blade.Narrow blades can't tensioned as tight, and wander off by grain that isn't parallel or perpendicular to the cut.Blades that are unequally sharp, or unequally set on left and right teeth will pull to one side.Fence should be as tall as the board you are resawing.Rig way to apply pressure to keep the board firmly against the fence. This should apply pressure from top to bottom of the board.Verify that your fence doesn't deflect under pressure. There is a reason that commercial fences are often made of heavy castings.

    How to Dig Your Own Swimming Pool

    If you can't see it, you don't need to clean it. <grin> Seriously, the only reason to clean it is aesthetics. The filters take out the floaties, and the chlorine takes out the germs.With clothes, black clothes attract white dirt. I suspect you would still see dirt on the bottom of the pool. If you didn't want to see it, you would paint it mud brown. This would be a serious optical oddity. We aren't used to seeing clear brown water.I think that black/dark blue/very dark green would be a safer colour, at least for caucasian swimmers -- someone unconscious on the bottom would be easy to see, much like a white styrofoam cup on fresh blacktop. If the pool is used by people with very dark skin, it would be less safe.

    Tiered Herb Garden | a DIY Tutorial

    Before building something like this, build a mockup and try to work in it. From such garden's I've made in the past this one will be very unpleasant to work the back/top tier as being an awkward reach.Design considerations: A waist high bench has easy access to about 6" under arms length. At 2 feet high you can get the same reach kneeling. At under a foot, you are essentially on the ground, and you can use shaft tools.Greater depths than this can be made much easier to use with strategically placed locations to stand. Pairs of bricks, small pavers.Point 2.Put a double layer of weed barrier below the bottom. Grass is very good and infiltrating a bed even from feet underground.

  • How to Flatten Boards With Just a Planer

    The key is getting that box beam rigid enough. Two ideas:A: Since you normally run the board through centered, I'd put two more thinner boards on edge supporting the interior of the box.B: Another way would be to make a foam core beam. Use the grade of blue board used for road construction. Use the right adhesive, and this would make the beam far more rigid and only slightly heavier. You have to make sure that the glue is even or you get glue humps and valleys. I would look for a glue that can be spread using a notched trowel.***If you are doing a lot of this, having some sort of dog system that allowed you to pin/wedge the board in place instead of glueing it would be handy.

  • Recycling Styrofoam (EPS) Into Useable Castable Styrene Plastic at Home

    One thought I had about reusing styrofoam -- reuse it as foam: Suppose that you ran it through a chopper to get a uniform size granule, then used a solvent at a dilution that just made it sticky, then pressed it into blocks, like giant lego blocks.Cities could stock pile blocks as emergency shelter kits.

    Be cautious: Except for the essential oil, all of these compounds are toxic even in small doses. Toluene exposure is hazardous in parts per million. A lot of these are also explosively flammable. Styrene + gasoline is essentially napalm. Yeah, in practice a napalm bomb had a core of HE to spread it.

  • How to Disassemble a Pallet Efficiently

    It doesn't work with conventional northamerican pallets made from red oak. That oak holds onto nails that the boards shatter before the nail gives OR the nails break, leaving surprises when you are cutting up the boards.I can see where this might work with EUR style block separated pallets. Very few of our pallets are made that way.

  • Wooden Planter - Easy Recycled Pallet Project for Your Garden

    Hmm. Don't seem to be able to respond to an answer any more.PVA is only moderately water resistant. I wouldn't expect it to last longer than a year.Wood is a natural material. It changes dimensions with changing humidity. Look at any cabinet. Changing shapes are the reason behind rail/stile and panel construction. let alone being rained on and with a block of variable moisture dirt adjacent to it. It *will* leak. I did this with oak barrel planters. Turned them over, and banged the rings on until they were very tight, then secured with screws. 2 years of weather cycles later there is a 1/16 gap between each stave. In wet weather they expand, and compress the edge wood. Next time they dry they open up. There is a reason people tell you to not let hardwood floors get wet.

    "Once you get your pallets apart..." I find that I only get about 1 board in 3 off the pallet intact, and even that is badly mangled. After some struggle, I've come to the conclusion that it's not worth the aggravation.Caveats: When you water the planters dirty water come through the joints. Line the box sides, but not the bottom, with black construction polyethylene plastic will reduce this.Dirty water also comes out of the base. If you are on a deck this can be unsightly. Either build in directed drainage, or don't put on a deck.A wood planter like this has a fairly short lifespan. One side is continually moist.

Size the planter to hold 3 or 4 of these. Do the planting in the pots, set the pots in the planter box. This also allows you to do tricks like:* Keep a set of inserts with tulips and daffodils in them. They go in the planter in spring, and come out when they are done.* Meanwhile you have another set with summer lilies, and a third set with autumn lilies. The ones that aren't in the planter are in the back yard getting ready for next year.* In winter you can remove all the inserts, put the planter upside down on blocks to dry out. You can apply another coat of stain, etc.

The two panes can be separated with a putty knife and some patience. Clean up the edges, and you now have two pieces of safety glass. The slope on the glass may not be steep enough to reliably get water to run to the collectors. In addition, to maximize solar gain you want the angle to be roughly your latitude. So at 40 degrees latitude, you want an angle of 40 degrees from the horizontal.This makes the north side in-effective. So redesign so that it's a wedge shape instead of a roof shape.

The really steep north face then is in the shade, and so is much cooler than the collector side. This may improve it's overall efficiency. The north side doesn't need to be made of glass.***An open collecting bucket will collect flies, birds, bees. Use a closed bucket, and run the collection tube through a hole in it. A vent hole filled with a chunk of sponge will prevent it from vapour locking.***If used steadily salts will accumulate in the water, as pure water leaves. This lowers the efficiency. You need a mechanism to drain the existing water without disturbing the glass. Depending on how warm it gets you may have issues with algae.

    If doing it as a survival tool, using white plastic allows you to set up much larger ones with less effort.

Using slides AND setting them on an angle so that the drawer is self closing. Add a wood toggle to one side that can be used to keep the drawer open when you need to rummage. If you are called away and someone comes down stairs, they are more likely to see a fully open drawer.I gave some thought to this in my house on a stair with no winders, and decided that I couldn't do it in a way that was safe enough to for a household with kids, teens, dogs, and absent minded farmers who walk around with a phone.

  • French Cleat Tool Storage Wall and Clamp Rack

    Plywood is good in shear. The forces at play here are trying to delaminate the plywood. However either is strong enough, espcially if you glue it to the back. The risk would be a cleat splitting along its length -- more likely on the carrier, as it's a shorter cleat. Plywood would never split. The edge grain of plywood is rough. No way you could slide the carriers. With 1x4s you could sand the edges and slide them. One downside of cleats: They will collect cruft -- dust, dustbunnies...Test: Nail a 2 foot cleat to a bare 2x4 wall. Make a wood box, and load with sand or rocks until it rips off the wall.

  • French Cleat Tool Storage Wall and Clamp Rack

    Chuckle. I just asked why they were so close together. All his carriers span at least 2 cleats.

    From the look of the way you use them, you don't need a cleat bar every 6" None of the things you've made allow using the next row down. Probably get away with 1 every 12"Cleats can be easily made from 1x4 or even 1x3. This is cheaper than plywood, and the edge is cleaner.You have mounted the carrier cleat part way down. I don't think there is any advantage to this. Could just put the cleat on the top edge of the carrier.In some cases you would have something who's end fell short of the next cleat. Putting a block of 3/4 scrap on the back of the carrier will keep in parallel to the cleat board.Would look cool if you painted or stained the plywood before attaching the cleats.

    Possible issues: The water in the hot line cools during the time the shower is off. So if the water was hot enough to start, it will only be warm for your next pulse. This system would work best with a heater just before the shower head, not one at the other end of the house.As another idea for people doing extreme water conservation: Look at micro sprinkler heads. There are mist heads that do 4 gal per hour, and tiny spray heads that do 10 to 20 gal/hour.

Both of these features could be done at once by making it somewhat wedge of cheese shaped.* You have the triangle at the front that is unused. While making it more complicated, using this to create a storage box/camp kitchen would make the trailer more useful, and may decrease wind drag.

    Hidden Door, Bookcase Door, Secret Room

    Very cool. Good idea on the gate hinges. Why the uneven spacing on the hinges.I will be interested to see of the door warps. For a real book case the load is somewhat concentrated at the back, averaging at the middle of the shelf, but the support is on the front on one edge. Fair amount of force trying to put a skew twist on the back. The wheel helps with this.The other aspect is the wheel. If the door is used frequently will the wheel leave a mark on the floor?

It will appear like you are looking into a very deep well, and can see the water reflected from the surface. If you can see the boundary of the mirror, then you need to make the interior lighting dimmer. Use a grey or blue non-mirror film.A pale blue film on the top glass may make the reflection look like sky.You will know that it's effective if you see people look under the table and up at the ceiling.Not sure what lights and/or film would do to this. Not sure how far below the glass the the convex mirror has to be to make the illusion work. I saw one done as a halloween hellmouth that used a well about 2 feet deep, and sides done in vague red and black shapes near the top shading to a sullen red grey above the mirror.

    Tin Can Hole Saw

    If you have an existing hole saw, many times you can re-use the arbor.Cutting a disk slightly bigger and putting it outside the base will help stiffen it. Then, the first disk you cut goes on the inside to stiffen it from that side.Once you have a disk on both sides, drill 2 more holes through the base that are about 5/16 in diameter. These should be fairly close to the edge, and opposite each other. This will allow you to push a pair of bolts through from the back to push the plug out of the front.Put a set on every other tooth with a pair of pliers. Bend it about 1/2 mm (1/32 to 1/16 inch) in. Not quite a tooth width. This will slow down the saw, but will make getting the disks out a lot easier.

    Table Saw Disc Sander

    Hmm 2 degrees. 1/28 of 5 inches. .17 inches. Seems like a lot. Bet it would be hard to get sandpaper to lie flat on that.It only has to be enough to get the grain of the sandpaper out of the way. I don't think you care about scratches before 80 grit, so the cone angle needs to be 1/80th of an inch between center and edge.So now, you cut a chunk of 1x6 long enough to handle easily on the mitre slide. Recut one edge so that it has a taper of about 1/32, wrap a piece of sandpaper over the end, and now sand your cone onto the face of the plywood disk.

    Will plywood reliably take being spun at 3000-5000 rpm? If your disk has a void on the interior you might get an unexpected surprise down the line.Maybe use thin baltic birch and put a layer on both sides of the blade and epoxy it in place. Make the birch disks slightly larger than the disk to hide the teeth?

    Hmm. Once you have it approximately round, couldn't you finish it on the table saw itself? Mount the disk, and push a sanding block against it? Not all of us have lathes.If the disk is the same thickness as a standard blade, you can use the same arbor washers, yes?

    Good point. Slack off the belt tension? Steal the step pulleys off your drill press and slow it down?Pulse it turning it on for a second at a time?

  • BalloonSat Stabilization With Compressed CO2

    Right angles to the sun: Sun rays hit the cells at a 90 degree angle.Push: Atmospheric density drops by half every 18,000 feet. So at 90,000 feet you are at 1/32 of an atmosphere. At 100,000 feet it won't quite be down to 1/64. Call it 1/45, or about 1/3 psi. That is still high enough pressure that the fan's ability to grip will be roughly linear with pressure. It will move the same volume of air, but with about 1/45 of the momentum. Yes it would make more sense to redesign with larger blades. I would anticipate a bigger problem would be the lubricant in the motor freezing. At that attitude the turning forces are small, mostly residual twist in the support line.

    @itsmescotty. Please explain. Which detail are you concerned about?

  • BalloonSat Stabilization With Compressed CO2

    This is very cool. However, the problem with a CO2 stabilizer is common to satellites in general: You are using a limited resource. Once the fuel is gone, you no longer have stability.At 100K feet you have a pressure of about 1/30 of an atmosphere. This is still enough to grab some and push. Could you instead use a solar cell, a battery, and a small fan instead? During flight, part of the protocol would be to keep the solar cell as close to right angles tot he sun as possible to charge the battery.Lots of other experiments that could be powered long term this way.

Even in midwinter shop was warm enough to work in by 10 a.m. and remained so until about 5 p.m. If the rest of the building were better insulated it would still be warm in the morning.

    More likely polyethylene pipe -- available any farm store. PVC is expensive, rigid and environmentally evil. That said the water can get hot enough to melt poly, especially in summer when you don't actually need the heat for the pool. Using PEX pipe will reduce the chance of this happening,but it costs more.If you are heating domestic hot water, the vacuum tubes with the high efficiency coatings do a better job -- at more money. Use a simple cheap system as a pre-heater.

Another problem I've had is keeping the wire from slipping on the back set of bars. I use a fairly stiff high tensile strength wire. This class of device needs an easy to use positive grab for the wire here. This design still has this problem.Hmm. Wonder if I could expand this to use high tensile fence wire for poly pipe connections?

  • Modern Platform Bed // Hand Tools + Framing Lumber

    I went a step further with simple: We bough a box platform, a mattress, and 4 cinder blocks. I sprayed the cinderblocks white,and cut a scrap of carpet the size of the face for each. Put the fuzzy side down, put the block under it, and put one block under each corner. The joint between the box and the mattress is solid for holding bedding when we make up the bed.In my student days when I was even poorer my bed was a door and 4 milk crates, and a 30" x 72" chunk of 4" foam. Small spacers under the support crates allowed additional crates for storage under the bed with 1 spacer clearance. (I think I used scraps of 1x4 as spacers.

    Before you build this set up, make a mock up to see how easy it isn't to get out of bed. I have found that anything much more than a vertical 1 x whaterver on the edge of the mattress requires that I scooch over. It's a minor nuisance, but on one bed we had a 2" gap between the mattress and a 2x6 on edge. I eventually got annoyed enough that I turfed the bed.Also mock up the bed's foot print. You may have a huge bedroom and the extra 2 foot width isn't a problem. In many rooms it can be. (We have a guest room that a standard double wide only leaves 16" on either side.)Finally: Give consideration to making matching boxes that slide or roll under the spaces.

What if it made a LOUD (rf wise) beep every 15 seconds, and a lower power one every second.Also, if these became popular you would want to modulate it so that your tracker could be distinguished from other trackers.The biggest problem is that you don't know when you want it, so when you do want it it's probably got a flat battery. A much more sophisticated version would echo. E.g. it listens on one frequency, then chirps for a while.

    Coarse woods will need some form of filler. You need to get the wood both smooth and flat. These methods are not going to work well on barn wood. Good 1 side plywood, luan board (used for supporting linoleum) baltic birch plywood (available in very thin pieces. MDF board may work too, but the high glue content may pose a problem. MDF glues may release formaldehyde on heating, another liver killer.1. Use acetone in very well vented circumstances. Breathe as little of the fumes as possible. It's hard on your liver.Laser toner is very fine particles of iron coated with a film of plastic. In the laser a heated roller fuses the powder to the paper. With the acetone process, you are dissolving the plastic so that it doesn't stick to the paper. When the acetone dries, the plastic is left sticking to the wood.Acetone dissolves lots of kinds of plastics, including acrylic bathtubs, and some synthetic fabrics.2. Clothes iron.If it has settings, set it to linen. Give it time to get hot. Modern irons often will turn off if they are left to sit for more than a few minutes. Do not use with steam. Because both the wood and the iron are flat, you may have voids in the image transfer where the iron doesn't make full contact. Try a pad of paper towels. Press HARD.You may want to try pre-heating the wood in an oven at 400 F for a few minutes. This will make the wood surface perfectly dry, and the iron doesn't have to heat it up as much.3. Water based varnish.This one has the best chance on less than perfectly smooth wood, and also on coarse grained wood. With the latter you may want to put one coat on, let it dry to fill and seal the surface.It may help with this mode if you can print onto a slick finish paper. The paper surface is sealed with clay, so the varnish won't soak into the paper as much. This make make removal later easier. The use of a shiny paper will make drying time a lot longer.Warm water will work faster to soften the paper. Try the steam setting on your iron, or a wall paper steamer.If paper doesn't clean off well, try soaking the surface either with an acid (muriatic acid from the concrete products section at building store) or with a strong alkali (draino and warm water. Both of these chemicals will dissolve you as well as paper. Nitrile gloves, apron, and a face shield. Using it diluted is a lot safer, but slower. Have vinegar ready if working with draino, have baking soda at had working with draino. Have a garden hose with shutoff spray nearby. Or work in the bath tub. If you spill rinse off with lots of water then apply the neutralizing agent. The acid is safer to work with.If your fingers wear out rubbing, use the rubber finger tips used by people who work with paper a lot. 4. Gel. I plead total ignorance.5. Laser. Due to dot gain, you may need to half-tone the image at a coarser screen size to get reliable results. You also may find that you need to change settings for images (where you want just enough heat to mark) and text (where you want it black.) If you are attempting to do grey scale (dots of different density) you may need to calibrate the laser. E.g. 50% of the exposure may give 80% of the dark. Google Printing dot gain. Laser on wood may have issues with grain. The grain, being darker reflects less light initially, and so heats up faster. Try a test image that consists of a step wedge (greys ranging from pure black to pure white) done at various half tone grids.

  • SUP Surf Board (from Homecenter Materials)

    Even styrene foam comes in multiple grades and densities. In general EPS is the stuff made from individual beads. When you cut it you have beads everywhere. XPS is cast in the sheet. When you cut it you have really lightweight saw chips. Don't use EPS for anything structural.Here EPS is marketed at Home Depot as 'bead board' and is always white. You can see the bead structure in it. XPS is either blue or pink, and you can see a much finer structure. Picking up a sheet it's much stiffer. For people who want a larger board, specialty wood shops can get plywood in 10 and 12 foot lengths. If you make it 8 foot sheets, you will have to laminate. This will nearly double the weight of your board. You can get Baltic Birch plywood as thin as 1/8" but it's pricey.The notch at the...

The minimum drag shape will be asymmetric with the wide point about 40% of the distance from the front.If you want to find out if you like stand up paddling, a solo canoe works well, and can be rented easily. It has other possibilities too.

    Solar Powered RGB LED Magic Pathway

    When you work out the light posts bear this in mind:The worst time of year for solar power is winter. The sun is low on the horizon even at noon. (Unless you live in Florida) So angle the solar cells to the south to collect maximum amount of light on the shortest day of the year. The correct angle is your latitude away from being flat.

    Chuckle. It rarely even gets that hot here. With the greenhouse closed interior temperatures could get 30 C warmer inside that outside.Example: I had 3 barrels of water overwinter. Now here in Alberta -40 is not uncommon in winter, sometimes for days on end. And while the sun and reflection off snow can be intense, it's onlly for about 8 hours a day midwinter.The maximum amount of ice on those barrels was about 2 inches.

    How do you keep the compression block square? Tip: If you are trying for consistent thickness, WEIGH the plastic on a milligram kitchen scale.

    There is no glue that is rated for polyethylene. With a rough enough surface epoxy will give some grip, but it isn't reliable especially with temperature changes. The usual practice is to weld them. Welding equipment for PE is fairly cheap. Screws work well too. If you need a water tight seal, silicon seal backed up with screws.

    Warning to all Greenhouse people: The degree of venting you need will seem unreasonable. I had an 8x8 greenhouse with a full sized door on one end, about 8 square feet of window at the other end, and a 3000 cubic feet /minute box fan. It would still get 10 C degrees above outside temps. Commercial greenhouse operators typically figure on 1 air change per minute.Failure of your venting system can result in over heated conditions in minutes.For this reason, I recommend that you build a first attempt very cheaply to test your ideas -- e.g. use clear tarp instead of expensive polycarbonate -- figure out ways to make the bottom 4 feet on two sides openable, put TWO fans in. (Fan life in a greenhouse environment is a tough one.)

    Very cool. However 10A at 24v is only 240 W.I can see merit in having a longer coil, also having control circuitry to vary the amount of power. This has potential as a great annealing oven.

  • How to Make a Super Secret Safe - for Less Than $3

    Caveats on reusing an existing electic box: The standard duplex outlet has live screws on one side. A coin touching this screw and the box or a ground wire will short. In a plastic box, a coin touching a hot screw is itself hot, and can shock you.Placing it in a cable outlet box, or a ethernet networking wiring box is safe.Electric code requires that wires only be joined in a box, and that the box may not be covered over. So you occasionally see a box with just a cover plate. Usually it means someone did a reno, and a wire came up short. No one would normally ever open one. This is the best scenario. One good place for convenience is beside a window. Most windows will have a double stud framing the opening, so the box will be 2-4 inches from the trim, and will be covered by the...

This allows a box at a height that doesn't require getting on your knees.

    Hmm. The key is that they all need to be also useful enough that you don't throw them out by mistake. I can just see me putting my coin safe in a parking meter. Or it is part of the kid's allowance. I can see putting the log on the fire. Or getting rid of that book on the History of the Peleponesian Wars. Or using up the foam in the spraycan, and dropping it in the trash.I'm my own worst enemy this way.

    Some thoughts:Pay close attention to sealing on any break in the front. You're going to be hitting raindrops at 60 mph. Amazing where those drops can get to. Your use of foam insulation is wise. If water gets in it's less likely to soak the insulation and remain forever.If you extend the front to cover the triangle between the bed and the hitch, you can get some extra space for free. It will also lower the air resistance when towing. This makes the roof a LOT more complicated. For your present roof you could get away with using standard ribbed sheet metal roofing. It has enough flex to install on a simple curve. You cannot do compound curves with it.When wiring consider running dual electrical system at 110 and 12v or 24v You can sometimes pick up RV devices that run directly o...

It has enough flex to install on a simple curve. You cannot do compound curves with it.When wiring consider running dual electrical system at 110 and 12v or 24v You can sometimes pick up RV devices that run directly off of battery level voltages.Another bed idea: start with a futon. This is quickly convertible between bed and sofa.Another starting point is an existing RV. I've seen well used but functional RV trailers go for about $100/foot. A fixer upper may be a better deal that building from scratch.If you start with a deck over wheels trailer, you get an 8 foot width. The price of this is stability. The centre of mass is higher so the trailer will sway more on corners. Now you can build storage under the deck, either accessible with trap doors from inside, or available as underframe boxes outside. Lots of RV's put water storage, the batteries, generator, air conditioner in this lower space, as well as lockers for things you use in camp, but not inside -- lawn chairs, a dining fly, barbecue.I think you can lighten up the construction considerably: 3/4" is overkill. Use 3/8 or even 5/16. Use wood paneling on the interior. Most of the places where you used 2x4 could use 2x3, and in some places 1x3 (E.g. studs where two sheathing boards don't meet.)

    I don't think the 3rd support is needed unless you are really loading the shelf, and it would get in the way for bulky items. I have a pair of ramps for a trailer made from 2 2x4's and 3/8 OSB. I routine move a 300 pound wheeled auger and me (close to 200 lbs) up the ramps.
