OK, I know I'm not the only one here building on a tiny bugdet (so far I have $1120 into my curent project, and that includes the purchess price) And building this way has taught me a few tricks along the way. So I was just thinking we could start a thred where we all shear our best low $$$ tricks/tips. I am making a oaisis "trail head" style air comp. for about $100 1) get a goodsized A/C comp @ the 'yard (York or tecumse are best) 2) get a starter motor from an old N ser. ford tractor (also Ford cars and trucks from 50's) 3) decide on youre drive, I'm going side by side with them so I'm useing a #40 chain drive for mine, but U could go face to face and use a "Love Joy" style drive. 4) make a bracket that they bolt to and get a 100-200A continuis duty sol. and bresure switch As soon as my motor gets here I will get it mounted and post pics if U like.
