tool that you made

Tom,

The Grizzly wheel is a good option but it's designed to be a driven wheel and has no bearings. You can either machine bearing pockets in the wheel or mount it in pillow block bearings. Here's a picture of the set up which I am pretty certain is from Deker's grinder build sticky on Bladesmith. I saved a bunch of KMG pictures from all sorts of sources before I started building mine and this was in my file. Deker, I hope you don't mind if I share it with everybody.

Thanks for the info on the Sunray wheels Ken, thats what I suspected all along, but never heard anyone say for sure. So you saved me the money and annoyance of finding out myself. :thumbup:

I'll take a look at the Grizzley and see if thats what I want to do, I think it may cause some issues with the set-up I'm building, I'd pretty much have to machine out the pockets for bearings. Great info guys.

i have now made 3 wheels from aluminium all under 3" and I have taken a 10" wheel from Grizzly and machined it to take bearings and have done the same with a 8" wheel from contact rubber that was used as a drive wheel on my orginal 2 wheel grinder that I converted to a KMG clone. If you get some r82s bearings and machine the hubs to take them and then make a spacer that has a 1/2" id and say a 5/8" od (I uses a piece of 3/8 pipe drilled out to 1/2" id) the spacer needs to be of a length that it just fits between the two bearings and keeps the bearing centers right when you tighten the nut holding the wheel on the tool arm. I do need to figure out how to put a rubber cover on a couple of the small od wheels.

This mite be to shade-tree of a fix for you, but I have used this rescue tape for a tire on my bandsaw. Has been holding up well for 5 months now. Have also used the rescue tape to make a crown on my Grizzly grinders tracking wheel, I use the grinder daily. I'm going to try the tape on a wheel for the NWG I'm building.

ib2v4u why not just use shouldered bearings instead of the spacer on the ten inch wheel? Don't suppose you could whip out a couple of those small aluminum wheels for a decent price, heh? All this stuff is just so expensive, puts a damper on the drive to build it when the cost gets so high.

for anyone with the 10"grizzley wheel, is the bore size 5/8" or 1"? It looks like the grinder description says 1". That could actually make it easier to put bearings on it if it is.

Syn, I believe the Grizz arbor steps down so that the wheel has a shoulder on which to rest. The wheel's bore is 3/4". I have one and these are the bearings I used when I built my grinder.

the R82s bearings are 1 1/8 (1.125) If I remember the Grizzly wheel was 3/4" was not hard to do. Hardest part was getting the wheel square and centered on lathe. You need to do that on both sides of the wheel. I used inside out jaws and the inside of the outer rim to position for boring bar. I could see if I can get some more aluminium round stock drop at work of a diameter large enough to make some more wheels. I am about out of bearings though. I bought a small lot of them of ebay. I would be more interested in trading than selling. I do not want to become competion for Rob or Tracy. They offer good stuff at a decent price for us.
 
Right on Polish avenger, I thought I'd figured out the bore size(you'd think Grizzly could list that huh?) but bearings to go straight in are a bear to find. Thanks

ib2v4u, let us know what you figure out or decide you can do. If you do decide to do something with it, don't worry about the bearings, if you just sized the wheel to fit that same 1 1/8" size bearing, those are easy to find. No reason to put yourself out any more than needed.

Pin press w/8 ton jack. I'd use a 12ton on my next one.

I've made a few of these. I'm working on another one with my 14 year old son to get him away from video games.
