I don't know how I missed this thread until tonight but I did. I don't see how you can go wrong for a hundred dollar bill. Can't wait to see how you guys like them. I also agree with what Timothale said Ron Covell said. The frame does not have to be as rigid as people think. Mine is way over kill but we made it in about 1990 and to be honest neither me nor my friend that did most of the work had any experience with one so we were kind of flying blind.
When you all get a chance to play with them post some pictures and show us what you are doing.
If it is in your budget, get a copy of John Glovers video on making a model A front fender with an english wheel. By the time he makes the fender he covers about any shape you can imagine. It will be a real education for you.
