I had some wheels done by a company in California at a school that I taught at and they were very bumpy and very inconsistent.  If you are successful at doing it at home and they work for you great but I just cannot see the math in paying shipping both ways and the cost that they charge to get back wheels at a cost only about twenty bucks less than a new Nova. The right epoxy is not cheap and add in the diamond and I still do not see the math vs. a brand new wheel.

That makes sense. I've heard nothing good about refurbished wheels.

Anyone know of a good source for some 4 inch Nova wheels?

The Day After

Hi All

I hope all had a merry Christmas.

I have an update. Do not use the plasti dip to try to re coat your wheels. saved15 headbang18

They started flaking off and exposing ne rough diamond that left scratches. I still will use the 400 and 800 recoat till they wont work any more.The 1200 wheel had to go because of back up I had to switch to the flat lap and that is way slow.

Knowing that I got an expand drum and 2 belts 1200 and 3000 grit. It arrived about 8 pm in Wednesday  shocked30 It works as I had hoped ura12 I was able to final sanding and polish 12 stones on the average 5 min. per stone dancer27

I got all of my presents finished in an very late night.

Bless

I've had nothing but good luck with my refurbs. Long lasting, great results. But I'm not paying shipping etc. Cost ends up about $30 per wheel, but I end up with 8 in diameter, 3 inch wide wheels. Lemme tell you, working on a 3 inch wide wheel is a dream! I'll never go back to skinny wheels. And no, I don't use plasti-dip. I use epoxy.

Hey Phil

Thanks for the input. Being the rebel that I am I went with the plasti dip because I did not see any total yea or ney. So I say a big no on the plastic dip. Now how do I get rid of it so I can try the epoxy?

I will be looking for some used wheels soon so I can keep on trying.

Bless

I have used the G-Flex epoxy as PhilNM and had no problems except what I caused. I initially used too much epoxy causing the coating surface to be too hard and no flex. I only had the thickness 1/16" to 3/32" thick. I have since found out, for my use, 1/32" is the limit and still requires a good dressing to get to where I like.

I generally wait till I have at least 4 wheels to refurb. I have a 80grit sintered diamond wheel so I do 2 wheels @ 220 to 280grit, 1 @ 400grit and 1 @ 600grit. My 1200grit and 3000grit last so long I haven't had to refurbish anymore. For my final polishing I use a 3M 50,000grit or tin oxide on felt and/or 100,000 diamond on canvas.

I have used Jackson Bros' wheels, one time, the 280grit was hard as a rock and came apart so quickly it destroyed a nice star garnet cab. The other was a 600grit and was starting to separate so I changed it out for one of my homemade one's. Both wheels were about 3/8" smaller in diameter than the normal 6" wheels too. I like to recoat the worn out Nova's or similar wheels.

Hey Don you old phart.  How are you?  Merry Christmas to you and yours.  Happy New Year to.  I haven't been doing much with rocks as we bought a fixer upper here in Oregon and moved in lock stock and every barrel of rocks....  Been doing a whole house make over.  Its fun but would rather be working with the saws and rocks and polishers.

Of all the things I've lost..I miss my mind the most.

Whether you think you can, or you think you can't, you're probably right.

Hi TOG,
You old fart and I hope you had a Merry Christmas and will have a Happy New Year too.
I have been so busy and with my health problems too I lurk often but tonight I had to add a comment.
It's good to hear you are keeping busy and not bothering anyone. I'm sure your house is looking good. 
Hurry up and finish your house so you can get back to your rock's. Lately I have been cutting and grinding, and selling, a lot of Fordite. I believe it is just a fad but I'm along for the ride. I still do some quality stuff though.
Work safely....
Your friend.

Don

Shawn,  no idea how to get rid of plasti-dip other than sit down and work at peeling it off. might be better to get someone elses worn out wheels and start over. When I do old Nova's for my friends, I remove the belting completely, down to the foam, and epoxy on new canvas. Maybe that will work for you. The hard part is keeping it seam free..... you really gotta pay attention to that.
The one time I tried plasti-dip I mixed it 30/70 with epoxy. It was OK, but not that long lasting. My current method works for me, so that's what I'll stick with. I love the 3 inch wide wheels I made.....  now, those 1-1/2 wide wheels seem almost too small to really do anything.... and 1 inch? forget it!

Hi All

Thanks for the input. Now maybe I have a plan. The G-flex epoxy seems to be next. I have to look that up.

Hey Phil I do have a nova wheel that I tried to recoat with 1200 grit that is of no use to me now that I got an expand for my far right wheel. If you would care to give details I would love to "skin" this wheel and make it a 800 grit wheel.

Bless
