Re: Talk me into or out of buying this Mark VII

I think $550. is a fair price for a restored one. Looks like it's been restored(new paint, some new bearings, looks like a new 3D printed plastic rack on the tie bar). Here is a link to another thread where I posted pros and cons of a mk VII as I see them. https://forum.shopsmith.com/viewtopic.php?p...

Re: Tachometer

"Both 'answers' still beg the question 'why'(does it matter)."

For me the act. speed isn't that important. It's learning, experimenting and playing with the Arduino.

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: 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...
