i have an old mark one with the big motor two speed. i’m going to cut that off at end of aluminum base and replace with a small high torque 110vdc motor and speed control i got from china(motor $15)tested. as for any parts etc. i will make them, doing so for an ultra tec missing the head. and making dops for others whom can find any or the maker is charging an arm and leg for them. this head i’ve made completely as they have none for older machines just made dops for lee for michigan guild members to get started. i’ll be 80 soon but as long as i can i will see/help faceters get going and keep going.
