The problem with the class idea is that once you certify that someone is capable of doing the work, then you take on liability. If improper assembly happens, the person can now claim that you trained and certified them.

I think Keith is trying to tap into the DIY guy who is not going to pay him to assemble the engine anyway. Now the DIY guy is going to use a machine shop to do some work, and he is going to buy parts. So sell him the parts and do the necessary machine work for him and offer it in a convenient package. I don't see how selling parts in a package adds any liability. You certify that the parts were in specification, when it left the shop. You have no control over shipping, and it is the responsibility of the purchaser to inspect for shipping damage. You state you have no control over the assembly process and the purchaser assume all responsibility for assembly. My suggestion of a book and video was to do two things. One, reduce the number of DIY disasters, and two, have the moral high ground that you went the extra mile to give the DIY guy the information he needed. If he fails to take advantage of it, too bad for him.

The option should not be designed to decrease the number of people who would pay to have a complete engine built.
