The build is complete, at least for now. We'll see what, if any adjustments are necessary or desired.
Viel turned around and tilted on its back, set up so the USB/knife jigs are out in front of the top/passive pulley, with the point of contact along the platen close to the pulley. I have not installed the reversing switch yet, but I have reversed the leads inside the control box so the belt travels away from the knife (edge-trailing) in this position. This position keeps the lengthened platen available for edge/tip repairs, bolster treatments, etc.
I built it so the whole assembly could be tilted up so the sander rests on its factory feet and can be used in the upright/frontal orientation, such as using the Viel platform or free-hand deburring, etc. In this position, the belt is traveling downward, so is not usable for sharpening so much, but more like the traditional 1x30" benchtop belt sander. I have one and am considering retrofitting it with the same variable speed motor.
As could be expected, there is always something. The MicroAdjust (MA) nut, if screwed all the way up on the USB upright interferes with the stock adjustable collar. I have two MAs on each USB, on at the top and one down on the Horizontal Base (HB) (or T8 case) as an aid to keeping the calipers parallel with the upright when setting heights using one of the angle calculating apps.
With the USB so close to the HB, it may be more difficult to keep parallel, if using calipers. I am thinking it would be faster and more definitive to make some spacers to use between the bottom of the USB bar and the top of the HB, eliminating the use of calipers for standard angles, such as 12, 14, 16 and 18º and permitting not having the MA right up there at the top.
Dust collection is next.
