Hello peterclahane,

According to the manufacture the Miter Gauge part number, AC1021 is no longer available. You might try measuring the depth and width of the miter slot. There may be another on that would work.

Good luck,

If you find one, please email me with details. I have the same problem. link removed

Hello 1140752,

The AC1021 Miter gauge is no longer available. As mentioned before. If you could post the width and depth of the miter gauge slot on your sander, I might be able to come up with one that will work.

If I understand your question, you do not need a 1/2" rubber spindle because the machine shaft is 1/2" and accepts that particular
size without a spindle. I had to figure that out when I went to purchase replacements for the 1/2" sleeve and discovered that this size slides right over the shaft with the washer and lock nut added on top.
I hope this satisfies your query; good luck.

Hello ekoizumi,

According to Ridgid there has been a service bulletin issued regarding this sander, depending on the serial number of the unit. If you contact your nearest authorized Ridgid service center, ask them to look at the service bulletin on the model and serial number or your particular sander. Explain your circumstance. They should be able to assist you.

Bushings in Idle Drum need to be replaced, order parts for new model it has ball bearings instead of bushings. Order the B19 Guide and Idle Roller plus the shaft and bearings to retrofit the older model

the problem is the top motor bearing. it is a solid bearing not ball bearing like most good motors. it wears and then the armature is off just enough to cause the motor to shunt and not spin. there is no listing for this bearing, just the complete motor at $290.00 us, therefore the sander is now junk, ready for land fill as are most things made in China. I confirmed this by shimming the shift of the motor with shim stock, the motor spins and works fine but the shim will not stay in place.
