I finally got around to posting the completion of the sanding platform with dust collection. Dust collection is working very well with just a shop vac.
The platform pivots out of the way for belt changes while in either the horizontal or vertical positions though you have to move the sander to the edge of the bench so it can swing out of the way. I need to add 2 more feet to make it more stable in this position. By swinging the platform out of the way while in the horizontal position, you can also run longer boards across the belt from end to end.
Dust collection doesn’t work quite as well when I use the top roller to sand an inside curve but it does collect most of the dust. Note that sanding with the top roller works very well. I was worried that tracking could be a problem while using the top roller but it doesn’t seem to make any difference. I do have to adjust tracking when I change belts but I think that is because each of the different grades of belts is a slightly different length. I also made some shims out of a soda can to improve the racking that I was getting which helped a lot. Tracking is working very well though occasionally, it does seem to suddenly track to the side for no apparent reason. Adjustments with the tracking knob quickly pull it back into alignment.
I still have plans to make an adjustable tool rest but that may have to wait until after the holidays.
