The panels were housed in grooves on all four sides. I routed a groove in the center of the frame, all the way to the ends of both the rails and stiles, then just filled the gaps at the top and bottom after assembly — I didn’t think any one would ever be able to see the fix.
Lol! The center pint is slightly off center by the extra thickness I had to add on one side. Would have been invisible if it was centered.
Anyway cut out the curves, need some spoke shaving and spindle sanding to clean up the bandsaw marks.
It is an insert head. The chips are very small similar to what you get from a sharp chainsaw. Clogging has never been a problem but I get spoil kicked up onto the infeed table area from the head. That is no longer happening :-)
