    Resin Penny Floor Project!

    Casting resin is not very hard. Even the resins used with fiberglass aren't very hard, they often have silicon powder added to reduce abrasion. This can work as a panel that you don't walk on. Could work on a coffee table. Not suitable for a kitchen counter.Minor scratches can be buffed out. Read up on renewing acrylic shower doors -- and note that acrylic is harder than casting resin.

    Downside of vaseline: Attracts crud. If your shop is primarily a wood shop, the vice ends up coated with a layer of vaseline and fine sawdust. A small amount of carnuba wax dissolved in hot turpentine works well. Put in a spray bottle. Flammable. 2-5% wax. Idea is to leave only a thin film on the metal. Let sit for half an hour (depending on temp -- colder = longer) and buff off the excess. Works for tablesaw tops and saw blades too.Tool companies sell a spray can of some wax in a carrier that does the same thing, and doesn't clog the nozzle.

You could get this effect with multiple layers with tints.Aesthetics: This is a matter of taste, but are considerations if I was at the silent auction bidding on this item: The legs are clunky looking. Possibilities. Use a leg style that are close to invisible. 3/8" iron, painted black? Pieces of driftwood?I don't like the red rock. If I'm buying something for my house it has to look right.

    Very cool. Any particular tip or wattage of soldering iron?Tip on doing photos of glass: A: Use a solid background colour that is dark, but not black. A dark coloured towel works well. In your pix, the graph paper background is confusing.B: Use coloured glass if you can. Green or brown is fine.C: Multiple light sources. One should be somewhat diffuse. A flood light works well. The other should be a point source. A clear tungsten bulb works, as does a CREE unfrosted LED light.***Putting a duck tape handle on the glass that is going to be removed makes it easier to deal with if it falls into the bottle.

Or cut out a hexagon out of coloured cardboard, and use a spray adhesive and attach the snowflake to the face. This will be more permanent.Sandwich tracing paper and aluminum foil when folding and you can make foil ones too. Florists have foil in red, gold, and green. The tracing paper keeps the foil from binding on the edges when you cut it.

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.

    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.)

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.)

    The lamination plastic is between two layers of glass.

    Several good ones here.Airplanes have acrylic (plexiglass) or polycarbonate windshields. Scratches very easily. Steel and glass are close to the same hardness. I would be reluctant to use on my windshield until trying gentler approaches. Certainly try first on a corner.Alternatives:Drains: A roll of used panty hose.Screws: String, or duct tape.Scrubbing plastic: Scotch bright nylon pad, or Magic eraser.

    Very cool. Could you mount a camera on it could you fly it out of sight?Seems noisy. Is this due to the way the prop runs in a slot?

    Seems to me that positioning the cap is fussy. Would it not work just as well to fasten a block of wood to the 2x4? E.g: Put the cap on the bottle. Position the block so it touches the cap. Glue or screw to the main 2x4. Remove the cap. This will leave a 'cap thickness' clearance between the bottle and the block

    How to Sew Shoelaces

    The stitches will take a lot of wear. Use strong thread. If you are good enough with a sewing machine, you can add interest by using a heavy coat thread of a different colour.I was surprised to see that you can buy eyots (the metal ends) separately. This alone was worth the read, as I often wear out eyots before the lace is done.This also allows the use of various kinds of cord for shoe laces. E.g. Venetian blind cord, or sash cord, dyed interesting colours.

This allows the backdrop to be kept current.

    Very cool. However your default desktop theme (at least when you are showing it off) should be sepia toned greyscale.Also: Possibly faint sounds of a tiny steam engine where volume and speed depend on the %cpu being used.Set two small glasses into the box, with brass lids. One is filled with water, the other with crushed coal.A 'monitor' function on the screen displays steam pressure, generator voltage... Brass plate: Babbage Universal Calculator Co.

    Laminated 2X4 Work Tables

    Two thoughts: A: Depending on what you are using it for, you may want to put shelving underneath. If your are doing that, however you probably want a more conventional 4 legged table.B: Some merit in attaching a power bar to the table. If you use it as a work table and ever have more than two devices to plug in, this comes in handy.

    Bug Prank

    You can get overhead projector plastic that can go through printers or photocopiers. (Match carefully, the wrong plastic will melt inside your device.) This makes the trimming less fiddly.for a ceiling fixture it would be great if you could figure out a photocell, and propulsion system...There is a version of this for mac and for linux that every time you move a window, a raft of roaches scurries away, and hides under other windows.Another version of this prank requires either the plastic ones, or bugs that are printed double sided, and you drop them into the stream from a fan.How about putting them inside clear balloons, then create a mobile under a ceiling fan where they are moving fast enough that you don't know whether to pop the balloons or not.

    GroundFX Bed

    Interesting approach. Good directions. One suggestion: Do all your sanding before assembly. You will still have some touch up at the end, but it's far easier to sand when you can lay the board on a sanding bench. You do a better job on what will be the inside corners.You still have the main ladder unit that is queen sized. This may give you grief if you have a sharp corners (stairs with flights) moving in or out. At king bed size the box units are usually paired.My stepson made a queen bed, and ended up building two platforms that screwed together. This could easily be done here by using the same technique, but makeing two ladder boxes that were half the width of the bed. Because of the torque on the joint when sitting on the edges, however I would bolt together with 3/8"...

This could easily be done here by using the same technique, but makeing two ladder boxes that were half the width of the bed. Because of the torque on the joint when sitting on the edges, however I would bolt together with 3/8" bolts and washers. 4 to 6 of them. More ideas.We have a box platform as the bottom layer on our bed. It rests on 4 concrete blocks. Each block is on a cut out chunk of cardboard so the block doesn't scratch the floor. Not elegant. But cheap and easy to work with. Another approach to this: use the base unit rectangle, and two 2x4s on edge running to the edge of the box. Taper them to 1.5" at a 30 degree angle at the foot end. Run just enough past the head end to attach the headboard.. For this to work well the base should be about 2/3 in each dimension of the box. If you have the older style wire spring base that sags in the middle, add two pieces of 3/4" OSB flooring. Dress up edges as you wish.I've never understood the point of these box platform things except to get the bed to the typical height. Build the base unit higher, top with plywood, and put the mattress directly on the plywood. This gives the added benefit that the space under the bed is now usable as storage. (Lot to be said for making a bed that will fit a row of 15 gallon rubbermaid totes under each side.)

    I wonder: Are ther silent water pumps. Could you make a real 'river' table?

    It's beautiful, and the techniques would apply to non-live edge tables (or put the live edge on the outside)But the nature of coffee tables is to collect books and magazines. The only time it would be visible is when we have company.Still, very cool.

    You don't want a groove. It fills up with crud. You never dust something like that.

    If you don't have access to the rail, you can lengthen the hangers, and bolt what you do have to a timber to stiffen it.

    It would be easy to screw a pair of small wood blocks to the top of the door so that with the blocks hit the bottom of the rail, limiting vertical travel. If attached at one corner with a single screw, they could be pivoted out of the way if you have to remove the door.It is also a good idea to put 'bumpers' on the face of the door that is next to the wall when door is open. This will keep the door from scraping the wall while opening and closing it.
