1) Is there a way to adjust the belt tracking? I am finding that the right side belt is running off centre. In general I would run the belt on centre 95% of the time, but there would be 5% of the time where I would actually run the belt off the platen in order to soften a plunge line near a knife bolster (green box in photo). I tried to loosen and retighten the drive wheel but it didn’t help. I haven’t put an indicator on it but it seems true to me.

The belt tensioner at the top is both tension and tracking, all belts track a little differently, there is a set screw above the spring cup it uses the 5/32 Allen key (provided) that is used everywhere on the machine 

2) I am not sure the black support arm for the single side Tormek jig was included. I looked through the boxes twice but I can’t seem to find it. I will have one more look in the morning.

The Mitre rest is only supported from either side, it can be used on either side 

3) Could you please outline the installation and use of the dual-ended tormek jig? What about the holder in red? Or do I remove the machine screws on either end to use it in between both arms when horizontal?

The Edge Tormek mount is a long 3/4 x 1-inch bar that has 4, 12mm holes and 2, 1/2 inch holes located on 6 inch centers are for the edge long twin rail     the 12mm holes are for Tormek US105 bars to be used left or right

4) How do I use and install the mitre jig?

Thats a good question on an edge belt    The Edge Mitre feed great works at the moment only with  8 or 10-inch wheels.

5) The steel piece (Aluminum) on the end of each arm. A safety guard addition? If I wanted to remove it, take off the belt tensioning knob and then unscrew? Right side guard is a little loose. Tighten using same procedure?

 Take off the belt loosen the Tracking tensioning mounting screws until you can get at the Phillips head screw then remove the angle, re-install/tighten the Tracking tensioning mounting screws and make sure they are tight. reinstall the belt and adjust the tracking.
The aluminum angle belly guard is a safety item, should be left in place,  if you’re using the belts in the vertical they are not needed if being used on the horizontal they prevent you from getting your clothing caught n the belts

6) The plattens can be reversed and run on either side, correct? The tape that is on there is not meant to be removed either, right?

The Layer of Neoprene with Teflon is the smart platen surface it is intended to give the belt surface some character like a strop —-  use it if you don’t want it ill trade you for some plain platens with the returned other parts

7) Can you outline exactly what you are doing in your video to deburr? Are you using the foam-backed platten? Just applying a little more pressure, edge trailing so the burr sinks into the foam and gets knocked off by the cupping of the belt?

Good description  yes

8) Lastly, the bracket on the body of the machine in red. What is this for and what is the adjustment screw for? Any benefit to using the mitre adjustment screw vs the hex screw aside from being able to turn a knob vs use a hex key?

 In picture number one that is a regular tormek bracket I was experimanting with fixturing locations, as you can also.        The Edge workstation has mounting holes at strategic locations to facilitate a wide selection of wheel / belt approaches.
