Wow, that's ugly (the new wheel), seems like it was never bonded. What's the manufacturer have to say about it? I've set up wheels with anywhere from .75" to 1.5" to 8" (just kidding, the 8" was a 2 wheel frantom ). Wider spacings for larger cabs. Keep up the good, Dr Joe .

Stop collars should work for spacers, but take the set screws out of them. No need to scar up the shaft any more than you have to. I have a problem with using PVC pipe for spacers. It doesn't give enough contact area between the pipe and wheel hubs. Might allow the wheels to wobble. Don

I think it was "bonded" at one time but not very well. When I first got the wheels, everything looked good but as I was pushing it on the shaft, I noticed it was loose. I haven't bothered with contacting the seller. I'd like to try and use some sort of epoxy to re-bond it.

I was also looking at this Covington site: covington-engineering.com/flanges_pulleys.htmThey seem to sell some sort of spacer but I wasn't sure what a Shelby w/spacer is? Thanks for the set screw hint....that makes sense.

Diamond Pacific sells 1" ID spacers, but they're too damned expensive. You might try Graingers, or check John Deere or other tractor parts departments. Also any shop that does hydraulic cylinder repairs. They use stop collars on some hydraulic cylinders. Don

Another option would be schedule 80 steel pipe. Once again it would have to be cut very straight. Preferably in a metal lathe. It would give almost twice the contact area with the wheel hubs as PVC pipe would. It might cost a little to have the pieces cut, but a 2' length of pipe would give you a lifetime supply of spacers in any lengths you wanted. Don

Well, I decided to contact the seller (lapidarytool.com) about the 360 grit wheel problem. They actually responded the next day, but so far they have not been helpful. They have implied that they have sold tens of thousands of these wheels with no problems so I must have abused and broken the wheel myself. Unfortunately I used paypal and I'm outside the 45 day dispute window so I guess lesson learned.....it's definitely a gamble when buying straight from China because if something is wrong with the product, there is very little chance of anything being resolved in your favor.

The original spacers were probably thin wall aluminium tubing. I know they are on my Star Diamond. When, I added a third wheel, a 280 grit Nova, I used a pipe cutter to shorten the ones the original spacers. You can get the tubing from any hardware store, even the big box ones. The pipe cutter will make a good cut, and you would be money ahead buying two feet of tubing, and a cheap pipe cutter. For aluminium a cheap one will work just fine. Woody........if I was not on the wrong side of the pond, I would come over with a pipe cutter.

Here's an update....they just contacted me about sending a replacement wheel. I'm not sure of the details like shipping costs and if they want the old wheel back but it's looking like they are standing behind their product.

I was considering using my 10" miter saw since I have a non-ferous blade on it but I decided to just buy 1" stop collars which I think will work. I was going to do a fit check (wheels, stop collars, spacers) tonight, although I'll have to wait for the replacement wheel before final installation. I still have to come up with a hood/pan for the expando drum on the left side of the shaft. Justin

I put all the wheels and spacers on to the shaft and everything seems to fit pretty well. I now have 1.5 inches between the hard wheels and then 1.75" between the soft wheel and last hard wheel.

Hey Justin, I hope you took the set screws out of those stop collars. You don't need them.

Hey Justin, I hope you took the set screws out of those stop collars. You don't need them. I left them in, but didn't tighten them down on to the shaft. Is it better to take the set screws out and leave the hole in the collar open?

Unless the set screws are tight in their threads, it would be best to remove them. You sure don't want them coming loose and come flying at you.

Justin:
I bought a used FranTom last fall. It has the saw and vise on the left and had two SC wheels that were pretty worn out (dished), so my husband put in two diamond wheels I got fro jadecarver but left the 220 SC wheel in. It had one cab rest but he made another for the right side. He also had to add an additional water line for the third wheel. The water drip from above was never enough for the SC wheels so he screwed in a little rectangle of chamois which helped a lot. It works even better on the diamond as they need much less water to use.
I have pics of all of this...let me know if there is anything in particular you'd like to see.... Sue

My first unit was an 8" FranTom. You can actually squeeze 5 wheels on there, but it gets a bit crazy and 4 is much more manageable! Definitely don't recommend mixing 8" wheels and 6" wheels when you have 5 squeezed in. Cut my knuckles on the 220 grit 8" while working on the 280 grit 6" Nova next to it...

Sue Sue, That would be great if you could post a couple of pics of the cab rests and water drip plumbing. My unit came with a little water spitter but it didn't seem to be working very well when I tried it. Thanks! Justin
