Bought some steel this past week. I was surprised how cheap it was. $15 for a 12' piece of 1 1/2" square 16 ga tubing. Borrowed a welder and broke out the angle grinder. I got the rear triangle made and also cut out the rear dropouts today. I will admit I need more practicing with my welding, but hopefully it will hold up. Now I am looking for a donor bike. Got emails out on a few on craigslist, hope to pick up one tomorrow.
