I agree totally with JPG. Keep in mind .007" is approx. the thickness of 3 human hairs.

Re: Can you make your own motor speed controller? Perhaps

rpd is correct. The SS digital conversion facebook group is where I got most of my info from. Make sure you check the "files" tab. That's where the documentation is on how to do it. If you don't want to join the FB group I can post my doc files. If you just want to add a DC motor to the ba...

Re: Yet another 3D printed coupler design

A couple of observations from a plastic guy. -Dupont makes several different types of Zytel nylon ; type6, type 66, type 612, etc. each with different properties. Type 66 natural color is yellowish and is one of the toughest nylons; but can be dyed many different colors as can most plastics. The new...

Re: About that Mark VII melting problem

Some interesting stuff here. I finally see the color that the cam follower turned to that caused the plastic cam to fail. It looks brown, almost purple which would be 480 deg to 540 degrees which is where I would expect the nylon cam to fail. A couple questions: When I measured my hub length, I meas...

Re: About that Mark VII melting problem

No, I was thinking of the mkVII sheave. I thought the bearing and cam follower was swaged, dimpled to hold it onto the sheave. I didn't know the post was swaged to hold the bearing onto the follower. I thought it was probably pressed on. I think either repair you mentioned would work. I know the cam...

Re: About that Mark VII melting problem

Luckily, I have not had this failure but I do have few thoughts on the subject.

Re: New member, not sure where to start.

Would silver soldering the corroded contacts make a more functional repair?
