i dont own a machine shop but, i did have a lathe and milling machine that is still in new orleans (i now live in France!)
i do have some experience stick and mig welding as a hobbyist! listen, i may not be an engineer but, i am far from ignorant on modding!
i have rebuilt two triumph motorcycle engines a few years ago and did a engine swap in a honda prelude without help!........however, i prefere to play jazz to make my daily bread!
