Take the armature out and turn it over and reinstall to reverse rotation. All I have seen come this way.

The 3M098 motor has been discontinued, direct replacement is Dayton 52JE17. Grainger says ~$63. The difference is that the 52JE17 runs at 4.5 RPM where the 3M098 ran at 4.0 RPM, half a revolution per minute isn't going to make a difference on a saw.

I'm impressed, simple, basic and very functional, hard combination to beat.

Very nice job on mounting everything, then a furniture finish too. I would suggest one thing; cover the bolt ends sticking out of the case {motor mounts}, they will rip you good in a split second of too close. A piece of rubber tubing works good.

Not wishing to decide on either/or, I've not had good luck with either. For me the sugar turned into a sticky mess and Metamucil just disappeared; turned to water. I tried corn starch, with much better result, and a little goes a long ways. Just my 2cts.

In my 5-gallon barrels I run it for 2 weeks, maybe not a necessary amount, makes for a convenient amount of time for cleanouts.

This mornings paper said road conditions will improve when the ice melts, what a thought.

l like working outside weather permitting and this machine is handy for that. I do have a variety of plates for it, some came with it, some I made. I cut the slot in the motor end of the box, grab the tub and the slot, makes it very easy to move.

I prefer pieces of leather, for a 3lb. tumbler probably in ~1/4-3/8" roughly square pieces; 1/4 to 1/3 of the load. Any kind of leather, garage and estate sale stuff is great, but not split leathers as it wears out too fast. It does get a little slimey, some don't like that.

My way of building tumbler barrels, different than jamesp method because of differing material availability and cost. Lids on these barrels need to be tightened only hand tight with a nut driver. Spray studs with WD-40 after each use. Build tumbler barrels before building the rolling frame so you know you have it right.

I have made several out of the gray electrical conduit PVC pipe with industrial plastic ends. Normally make 1 gallon capacity {about 12 pound} which are 6" diameter and 10 1/2" long. They run pretty quiet, and a friend I made some for says he gets a better finish than with his commercial rubber lined barrels. Detailed information at your request.

A lot of basic machinery uses off the shelf hardware parts to make it run, your tumbler may well be one: I did a little poking around in a Boston Gear catalog today and found a gear that might be what you are looking for. It's a 24 DP, 12 tooth, 3/16 bore. Catalob # YP2412. I'm not certain this is right, but close. If you have a Boston Gear products retailer {generally an industrial supply company} available you might take your tumbler frame and the motor with the gear on it to them. I know the store in Portland Oregon is very helpful in this sort of situation, hopefully all are. The obvious reason I can't be certain this is the right gear is that you can't be certain of its exact dimensions in its damaged condition.

Might take a look at aquarium gravel at Petco if you have one, small round pieces and lots of polishable quartz super cheap in the bag I got for filler.

I think the idea of keeping it dry is that wet sandblasting media of any kind really fouls up the blasting unit, from the reservoir to the nozzle. Sticks to parts and clumps.

I have lost a couple pillow block bearings way too soon, did good maintenance but I think as with so much other stuff now the quality has slipped. You sure did a nice job on that piece of furniture.
