SCORE!! As I got down near the bottom of the mess of stuff that came with my MFC, I found the drawbar I thought I was going to have to make!! It is homemade from what appears to be a 1" piece of tool steel and differs from the original (in addition to the larger diameter outboard) in that the minor diameter is about 0.008-.010 undersize, there appears to be a brass washer to act as a "bushing" instead of the taper shown on the original, and it is tightened with 2 flats at about 0.75" instead of the half inch square shown in the drawing. BUUUTT, it works like a champ, and that's what really counts, isn't it?
At this point, it looks like I'll be able to make some chips as soon as I sort out the knee control so I can move the table up and down (assuming I don't find anything else hidden that is wrong with it!)
In the assorted mess of tooling, I found an arbor that appears to have an R-8 shank and a "stub arbor" with a #3 MT shank that I will try to find a home for, but still no usable arbor for the MFC.
The overarm looks like it will clean up well and be usable and the homemade brace to support the arbor from the overarm just looks like it needs a little cleaning up... it's "hell for stout" but really looks kinda clunky on that little machine. It's made in a sort of stepped manner about 2 1/2" thick up at the top then stepped down to 1 1/2" at the lower section. It also has a ginormous hole where the bearing/bushing goes for the arbor end, but that can be worked with, I believe. The adventure continues!
