DRT - Thanks for your continued interest and support. The bits that Pat, the Sommerfeld employee, mentions above might work. However, the CMT dovetail bit listed is supplied with a 5/8" bearing and definitely won't work because the template forks are only 1/2" wide. The simple solution, if these are truly the correct bits, would be to change the bearing to 1/2". Unfortunately, I would have to buy the bits and replacement bearing to test this theory. If it doesn't work, I would have to eat the cost of the bits and be no farther along than I am now.
I'm so curious, I might elect to go this route in the future. For now, I'll continue to hope that someone comes forward with actionable info. I'll also take your advice and post on other forums.
Again, thanks for keeping this alive.
