The original plans by Doug Ross are available here:
The plans are very detailed with instructions and photos.
My lathe is only a 7x16 so the grinder is a bit large for my setup so I did have to make some changes.
Biggest change was the length of the support bar that attaches to the tool post. I cut 4 inches from the length
and I placed two holes in the bar so that I had two options for mounting on the tool post.
The belt specified was not available. I actually ordered the belt and the supplier cancelled the order since it was not in stock.
I did have a few timing belt pulleys so I used them along with a 540mm x 15mm wide timing belt.
I also changed the motor to one I found on eBay that was much smaller and made adjustments to the mounting plate.
The spindle was shortened by 1".
In retrospect I could have changed the external grinding shaft from .500" to .375" to use smaller grinding wheels.
With the grinder mounted on a custom tool post riser and using the longest reach I have more than 3.5" from
center of the lathe to center of the tool post grinder. That should be enough reach for anything that I would need to grind.
Overall this is a great set of plans that can be modified to your specific needs without much work.
Thanks again Doug for a great set of plans.
I will post this build in sections since there are more than 20 pictures to post.
