I agree with voicecoil. My only suggestion when you cut the other one would be to support that overhang with an elastic luggage strap from the roof of your shed.

Hi Kit, I cut them both in one sitting yesterday, i measured the effect of the sag over the saddle with a DTI 4mm offset from the spindle (I used an 8mm endmill for the facing operation) whilst lifting the weight of the overhanging part, didn't really have any effect with the gibs tight as you would expect given the table pivots on the saddle. Probably not an acceptable way to fly cut but with a small endmill it works. I thought about slinging the overhang to my engine hoist but the problem with that would have been as the table is moved to the other end you would need to reverse the force since it becomes overbalanced the other side.
I think the best possible way to balance a job like this is to put a sliding counter weight inside the extrusion and move it through as the work moves (in the opposite direction), but I couldn't be bothered in this instance, if I was using the large fly cutter I would have had to bother else it would have cut a tapered scallop in the top surface.Last edited by devmonkey; 22-12-2019 at 11:26 AM.
