Hello Dave, I've been watching and learning as you go through your process on this build. It's going to look great when you're done. I just hope that all of the details will be visible when you are finished.

  Nice work!

I ordered some Badger Stynylrez "Metal" primer for the belt drive hangers, etc.  It'll be interesting to see how that stuff works on the pewter castings.

Now I know I've put a lot of discussion and detail in this thread.  But I suspect many of you might be interested in a machine shop model, so I wanted to let you-all know the kinds of challenges I've run into on this project.  It's definitely been a marathon, with lots more to go.

add:  There's a great segment on cutting and installing a belt on this video starting about 11:40 or so:  https://www.youtube.com/watch?v=I5TCh0jRX1k  One thing I realized after watching this is that you can use two pulleys on one shaft, one idler and one driven, with a double width pulley on the other shaft.  Here's an image from the video that shows 2 pulleys on one side and a double-wide on the other.

In the video, watch how the belt moves from the driven to the idler wheel by the gentle application of the crescent wrench as a shifter.

another add:  I measured my RGM pulleys.  The large thick wheels are 8" wide, each step on the cone pulleys are 4" and the intermediate size wheels are 6".  So that says my belt width should be 4" or about .046.  That should work OK.

I haven't been able to check in in a while - your build is coming along nicely.

Your shop floor is much better researched in terms of placement of machines and to create a logical work arrangements.  I really hope that the removable wall ends up working out, considering all the thought that you are putting into this project.

Will continue to follow.
