Ever look at all your junk in your garage and start to thinking how to throw stuff together?
Had a craftsman lawn mower next to a york compressor and thought, "huh, this has a nice briggs and stratton, why not make on board air?" Then I see an alternator and figure "hey here's my generator."
What I wanted to do was fit it all in the outside storage box on the pass side. The space we are talking about is 19.5" long, 14" deep and 12" high, not a lot of room to work with.
The lawn mower had a pulley to power the rear wheels and was run by a 6.75, 190cc briggs. I built a wood base from scrap and cut the base of the mower. It was already raised for the pulley, I just noticed it in a couple spots for the belt to go to the alt and compressor. I also had to shorten the shaft from the motor to fit within the 12" height. Got flat stock to make 2 "U" brackets for the york and used some other misc stuff to mount the alt.
Went to Grainger and picked up some fittings, check valve and pressure switch. Had the rest of what I needed from another project, including a 8 gal air tank. I still have to mount that on the opposite side behind the drivers seat.
But there ya go. It works pretty good.
Copy the 5 tons and have your own air and power!
