Thanks for the Leah Day reference I went there and was happy to see the video...She is great, isn't she!...
I couldn't use the clippers because with arthritis and nerve damage I can't judge pressure..either break something or drop it...I put the foot in a vise CAREFULLY and used the Mototool with the saw blade...was afraid it was going to buck and destroy it but it didn't. Used an Emory board and nail file to smooth the edges...took it for a test run and whoa what a difference it makes to be able to see where you're going. Now to conquer foot speed and fabric movement.
Thank you sooooo much for your input and encouragement...
