+ another request for info on your grinding (I think you said it was a Roloc disc earlier??). Really nice clean up
OK, here's the tool. They sell them at Harbor Freight but the discs themselves aren't nearly as durable as the ones made by 3M. I use the 36 grit to knock the welds down close to flush then finish with the 50 grit discs. They just twist into the adapter with a 1/4 turn so it's fast and easy to change them. They last quite a long time if you don't run them at high speed. Run 'em slow and you'll get the hang of it quickly. I love them moe than any of my other grinding methods for accuracy and finish. Hope you like them.
