Hi

Thank you for sharing.

Really like the connecting rod and remote handle to operate the attachment. Great idea.

I hope you don't mind, but I think I might try to incorporate something similar to your design to the one I built. This would be a great improvement to my tool.

Below is a link to my attachment, which you might find of interest as the cutting tool can be set using slip gauges to set the radius of the tool accurately.

Many thanks again and a good job
