I thought I read somewhere that plans were available for the adapter plate this group came up with. That Steve B is using to produce them. Trouble is, I've received the sander from Steve's supplier and the PSI variable speed motor but not the adapter plate - yet. I tried making one and it could work, but I'm likely to make a new one as there are some things I "learned" with this first one.
Can someone point me to these plans, please? I searched this thread but did not find them.
Also, in messing with the plate I made, bolting and clamping things together, I found there is not means for adjusting belt tracking with the motor hard mounted to the sander frame. That would be fine if the belt tracked well, but it does not. I also found that by lifting the rear end of the motor, canting the pulley a little, tracking was improved - not completely right, but improved. I also observed that the weight of the motor really pulls down on the rear of the motor. Having that much weight hanging out there like that has to cause some vibration. Has anyone actually noticed any such vibration? Has anyone noticed an adverse effect from the vibration?
Finally, has anyone gone to the trouble of building in a means of adjusting belt tracking? Given the design of the upper pulley assembly, with the spring loading, I am having trouble seeing a way to incorporated such adjustment to the upper pulley. Building it into the motor/mount/pulley could be done, but it would take a much different mounting method that a fixed plate between the motor and frame.
Several questions there.
Thanks,
Rick
