Aerospatiale helicopters use a root cover made of vinyl that is applied by softening with MEK and then rolling it onto the polyurethane paint to prevent air bubbles.

For pure power transmission with no requirement for backlash control a square thread is the best, for accurate backlash control the thread angle must increase...friction goes up as well. The Acme is a good compromise. Higbee cuts should have a 45 degree lead-in although I have seen cuts...

What is wrong with a type K thermocouple? I have a two channel calibrator that I have been using for at least 10 years now that does exactly what you are asking, O2 sensors are for factory cars. Forget tuning by A/F ratio and stoichiometric mixtures and start learning to do it by exhaust temp...

Bending speed is critical with stainless since it work hardens. You also need approx 1 1/2 times the power to bend stainless as compared to carbon steel, if you are operating the bender close to it's capacity then your running out of power to complete the bend. You could try annealing between...

You could use a good quality 1020 carbon steel instead of the higher carbon 1045, these steels work much better at low temps assuming you don't need to heatreat it to a higher hardness. I live in Canada and most outdoor applications require a low carbon steel to survive sudden load impacts at...

Silicone grease is the only thing that will stay put and last, coat your CV boots and other rubber parts with it and they just might last forever. I use vacuum diaphram grease, works really good on leather to seal out water too.

316L is a low carbon variant of 316, hence the "L". The main difference between implantable grades of stainless and pedestrian grades is the tracking process during manufacture of the raw material, much like ISO regulations they require the steel must be traceable from billet to...

Any compliance in the system tends to reinforce occillatory movements at certain frequencies, get rid of components that can deflect (rubber). Generally rigid bushing materials (Nylon, aluminum or even high durometer polyurethane) help the situation. Damping of course helps as in the Ford...

If you made the guide rectangular and the guide hole for the mass to match you could use two spring loaded channel beams made so that upon emergency application the spring pressure would force the two beams apart and through friction stop your load, high phosphorus cast iron shoes are used on...

Wheelchair vans use similar ramps and have even longer spans, 1/8" diamond plate aluminum sheet with tack welded 3/8" square aluminum tube stringers is strong, light and likely to be more durable than your other choices. Even u-channel will work well.
