I believe belts were moved to under the stairs by the artisan bench.
You are correct, thank you @JohnWickham for showing me that. I believe the switch is working correctly, but the air filter for the tracking definitely needs cleaning.
New 120 belt is on and should be good to go, just check the limit switches beforehand
I used it a little today. The thickness gauge and the sandpaper are way out of calibration. It’s something like 0.2 inches off.
I hear a repeating click that is associated with a lever arm rotating inside the machine. Sorry I can’t be more specific with the parts names.
After a lot of searching for the correct thickness setting, it did sand.
The thickness mechanism has been off for a while. I have an idea for machining a better mechanism, but I haven’t had time to make it and don’t foresee having time for quite a while. I’ll try and sketch it out for someone else to do if I can.
(I’d done the last repairs on that mechanism, but it has fundamental issues; I don’t think it will ever be reliable as it is now.)
I took some measurements and came up with a simpler design for a fix. I even went to start making it; I cut a raw piece and went to mill it … and the mill speed dial wasn’t working … and now the mill isn’t working at all … and Nutcracker starts Sunday … so ir may be a while yet.
New mechanism is in place, though I will change out the adjustment bolt for something larger when I have a chance, and get more appropriate holding bolts. I have it set so that using the mechanism gives you a first pass that barely touches the board’s surface when it puts thought.
If this (with a larger bolt) doesn’t solve the problem, then we might have to look at the mount for the switch. But it seems stable; it was always the lower part that moved or bent. And if this hunk of aluminum bends, we’re just out of luck.
Thank you Ethan
