    How to Deodorize Your Vehicle's Interior

    There are some misconceptions here concerning airflow in either real air conditioning or those that are incorrectly called air conditioning in motor vehicles. Running the heater to dry out the evaporator will have negligible effect in purging the moisture from A.C. systems since they use a "Terminal reheat" system whereas the incoming air is chilled first to remove moisture from the air and then reheated to bring it up to the thermostat setting. The heater core is downstream of the evaporator and it wont heat it at all.True air conditioning is somewhat wasteful on energy used to chill then reheat it to desired levels, and usually on lower value vehicles one finds a refrigeration system instead. The operative word here is CONDITIONING. Still.... even in a vehicle with (misnomer...

The operative word here is CONDITIONING. Still.... even in a vehicle with (misnomered) Air Conditioning: the heater core will be in a y-duct with the heater core in one leg, the evaporator in leg #2 and the discharge into the passenger compartment in leg #3. The heater can't send heated air through the chilled duct either way. If the air isn't at least processed to remove moisture, then the system isn't really conditioning the air. Even with the advent of cabin filters, there really isn't any true conditioning without drying the air first either.

    $40 Backyard Chair

    Be careful cutting and shaping PT wood as it can make you very I'll because of the chemicals used to infuse the wood. Once you cut into the wood, the newly exposed wood won't have any protection because the pressure treatment, contrary to common belief, does not go deeply into the wood. To counter this I sealed all the wood once rough cut and again after final shaping. In particular I cut off bottoms of plastic 1 gallon milk bottles and poured some wood sealer in them and put the bottoms of the feet into that solution overnight to deeply soak the leg redwood.This will protect the wood and keep it from sucking water and dampness from the ground when the chair is taken off the patio.Cedar.... no matter how wide or thick will tend to split like thinner pallet wood, so predrilling all scre...

I used exterior grade 1 3/4" Torx-drive deck screw to achieve a modicum of long life. I thought I was going to plug all the screw holes, but decided that was too much work. All lapped joints were also glued-n-screwed with exterior grade wood glue. Look for a gorilla on the label.....but don't used the urethane version. Urethane --- for me --- either dissolved or broke down in some crazy way on another outdoor project --- so I shy away from it most times. Besides, it's very messy to work with.My wife wants me to build a chaise lounge and a rocker now. Ugh!That said, I wanted a more rounded chair with nicer ergonomics and came up with this:

  • Poor Mans Repair Guide For Chevy,GMC Vortec Fuel Injector spider or CSFI System

    Stop right where you are before you spend any money.Why didn't you diagnose the system first? It's only nuts and bolts and a man can fix it if they don't just start ripping into the vehicle and their kid's college funds first. 3 second runs is usually a problem in fuel delivery. Get a FI Pressure tester and find out what the pump discharge pressure is, corrected for altitude, of course.

    One of the problems I've faced on these units in my shop and the mileage idea is just wrong as I've got 340K miles on my 2000 Astro and so far no repairs other than one fuel pump. One oddball problem with a code P0300 is the manifold pressure/vacuum regulator on the side of the spider. They will occasionally rupture there and even though the engine starts well cold, once warmed up and restarted, it will be flooded and pop a code like you have.This causes all sorts of thoughts that there's a problem in the ignition system which is an easy primary voltage test. That's usually a red herring. I can't believe that this is such a mystery. Changing batteries and starters is so 'way out in let field that I shudder at the sheer expense of not doing a thorough diagnosis of the real problem first.

    51 Cent-ish Fishing Lure

    Yeah - I collect 2x4s and 2x6s from construction sites and build them into bass guitars. I don't want to scoop your post, so I won't upload a pix here. Maybe I can get some pennies flattened by the train that goes through town tomorrow. The train is very slow and I bet the pennies will come out nice and flat.

    Uhh. Err. Balsa is technically a hardwood. It's an angiosperm.

    Table for a Cheap Tablesaw

    I make sure that all my cabinets and worktops --- including saw tables and drill press tables, routers, joiners, etc, have the same height of 34 inches from the floor. That way all your table/desk/tool tops are the same and it makes it very easy to have a long board spill over to another surface that's the same height. I sometimes retract the table saw blade and use the rolling table I built at a portable workbench.Since the project of choice for me is building guitars, then I use a Bosch direct-drive table saw much the same as yours and it suffices me well too. If I have something bigger to rip, I set up my aluminum channel fence and use my Skill-Saw worm drive that can make a nice cut too. I got rid of a ShopSmith as it was too large for me and I really like a tool to be single-purpos...

I got rid of a ShopSmith as it was too large for me and I really like a tool to be single-purpose anyway.Once in a while I will put my portable table router on top of the table saw and use the extra height to make some precision cuts closer to eye level. And all my power tools - with a few exceptions - run on 220 VAC.

    Just for more Steam Punk design, how about a second three speed hub in the rear wheel? That'd give you 9 forward gears and ONE of them should be to your liking!

    I agree totally since I can Google almost anything including a do it yourself trepanation. https://www.google.com/url?sa=t&source=web&rct=j&u...

    I don't personally feel this is very 'tech-y' at all. Most of it, once the products were named is pretty much PNP. The only oddball part was the ip/pg system that sends via hardwire power lines in the house. (Hmmmm. I wonder, since Montana is on the same grid, if this could be used to allow interstate IPG comunication... AS WAS PROMISED for the whole world a few years ago? Huh?) I digress. Sorry.FWIW: I have a steel roof over my 24x65 mobile home here, a on-top-of-the-refrigerator, very antique Netgear before-rubber-ducky-antenna system and get almost no signal loss even in my tin workshop, 60 feet away from it. I even get 1/4 mile down the road to my neighbor and coverage in my horse pastures and my tractor barn, although truth be told, the tractor barn metal doors have to be open for ...

I even get 1/4 mile down the road to my neighbor and coverage in my horse pastures and my tractor barn, although truth be told, the tractor barn metal doors have to be open for it to work well in there, but the horses don't complain.....yet. It must be the clear blue Montana sky here or some phenomenon under the steel roof that gets me this crazy range, but it sure works for me. I begin to believe that there are no valid rules on signal propagation - just voodoo science that sounds high-tech.

    How to Test Your Car's Alternator

    One more step. Turn OFF all accessories, and with the engine running - turn your DVOM to the AC setting and read the value. Be sure to run this test as close to the anternator output lug as posible since the nearer you test to the battery, the "softer" the signal might be and create a false negative. The battery acts as a huge "sink" or shock absorber for voltage spikes, but it won't protect devices forever that need good electricity. The output voltage on the AC scale must not exceed 0.002VAC or there is likely a diode problem. Modern auto computers - and newer vehicles may have more than three units - thrive on purity and quality of your alternator's output. Sine waves or spikes in the digital signal can cause a lot of havoc with on board ECMs, ECUs, BCMs, TCMS a...

Sine waves or spikes in the digital signal can cause a lot of havoc with on board ECMs, ECUs, BCMs, TCMS and such that can damage the computer or the system it controls. WARNING Analog meters should be used with serious caution for underhood testing as they may inadvertently get into a 5VDC signal or supply path and can load down the fragile system too much. You can damage sensitive electronics with analog meters and worse yet - test lights.
