I've always been handy, just never mechanically inclined. Now I find myself taking apart computer boxes to strip out wiring, power supplies, speakers, etc. I disassembled washer machines looking for water valves (haven't used them yet!). I'm breaking down fans and salvaging motors for uses in my haunt. I bought a welder last year after seeing a demonstration of how they worked and will soon be using it to build props.
Two weekends ago I did a Talking Boris hack and now have a really cool greeter for my yard. This past Saturday I built my first pneumatic prop, and I can already tell it won't be my last. I built an air cannon, which was a heckuva lot fun to do and even more fun to play with.
I learned today, however, the two compressors I own may not be big enough to handle the needs of the cannon. I can shoot it off after first pressurizing the tank to 80 psi, but after a few shots I need to completely drain the tank and re-pressurize it again to get it to work. Seems the cannons operate at an optimal pressure of 120+ psi. My torpedo compressor and my pancake compressor, though both say 125 psi max on the side, were struggling to hit 90 psi today.
Maybe it was the cold weather, but I was told if I go for an oil compressor with around a 30 gallon tank, I'll not have such issues for operating any of the pneumatic props I build. While it's a $350 investment or so (thank you Harbor Freight Tools for saving me at least $100!) I'll still be able to use my other compressors as reserve tanks. And I won't run into the issues I had with my paint sprayer and impact wrench which never seemed to have the juice to handle the task at hand.
So Halloween and prop building continue to open up new and interesting avenues for me I never would have explored previously.
