Now that's a loaded ?
I build engines and there is a lot to an engine even after its been machined that has to be done.
I do a lot of work to my engine before it hits the machine shop. I don't consider a machinist that works with machines (lathe as you put it) or any other machines a engine builder, just because he or she can run a lathe don't make them an engine builder. I know I few good builders that have there machine work done at a different shop.
So like Zip what dose that make me. Bj you and so do a lot of other people anyone can put one together but staying together is another thing.
