Hi Bryan thanks for the enthusiastic response it was great fun to do!
This is not a step-by-step guide but I guess the picture tells the story.
Cut the top of the sliding table rail so that it leaves a 27mm X 5mm channel. Insert the 40mm side of a 40mm X 30mm X 5mm aluminium angle into the channel and bolt through with enough play for height adjustment. Bolt the miter channel on top of the 30mm side of the angle making the holes in the angle oversize for lateral alignment to the VL. That's it!
The oversize holes in the angle allow for +/- 2mm lateral and height adjustments. In practice adjustments were in the range of 1mm with an accuracy of 0.03mm to parallel along the entire length of the rail. The 5mm thick angle has added a certain stiffness to the rail and requires considerable lateral pressure to deflect it, hopefully more than you would experience in ‘normal’ woodworking conditions. I also added a pair of additional holes to the sliding table rail so it can be mounted centrally when working with narrow stock.
My plan is to mount an INCRA LS-25 on the MFT/3 and an INCRA 1000-HD miter gauge on the sliding table. After squaring the MFT/3 and VL, calibration would be : - 1) Square the LS-25 to the MFT/3, 2) Extend the LS-25 fence over the VL and square it with the miter slot, 3) Square the 1,000-HD miter gauge to the miter slot.
The even Grander plan is to have dedicated OF-2200 and TS-75 CMS inserts so I can keep my TS-55 and OF-1400 free for bench work.
