Changing grinding wheel and replacing cam The easy way

Jeff · March 17, 2006, 11:25:21 AM

GET CHET TA DO IT! ;D

Chet and Judy stopped by for the evening on their way to da youngest Son's house to help him and his wife move into their new home. We had them trying out the Carriage House Inn for the evening, so Tammy and Jude went over there to relax in front of the Fireplace and Chet and I stayed here for a bit. Chet CAN NOT be here with out tinkering with something. Lucky for him I got the flapper valve in the toilet working fine, so I showed him the way to the Wood-Mizer sharpener where it waited with its box of new goodies. I was going to wait for pictures from when it gets back from chrome and powder coat, but these will have to do. :D (Chet loves to take things apart and put em back tagedder)

There is a short video clip here as well. You can hear on it that I am going to have to order some more parts pretty quick and tear it apart again. sounds like motor bushings. :-\

Anyhow, after drinking a couple beers and getting our hands dirty, we went on over to the carriage house (I FEGOT THE CAMERA :-\) with the girls and inspected the upcoming contest prize. ;D (Keep yer eyes open for that later today!!)

VIDEO CLIP WITH SOUND OF BAD BUSHINGS

I wanted to point out since the camera froze the grinding wheel in place while Chet was dressing it, that we did follow the instructions for the directional mounting on the wheel. :D

Did he get that green chainsaw running ???

Jeff · March 17, 2006, 11:39:36 AM

:D

The plan is that he is going to pick it up on his way back through and take it home to play with. He was real impressed with DanG's diagnosis of the problem and figured it was going to be a simple fix as:

"It ran right up until it quit" :D

He didnt have room for it because he had a packed blazer. He built Chris one of his wonderful oak beds and had that in there plus every other nook and cranny filled. I will come back and post a link to some of Chet's furniture. He is a master. From tree to heirloom is what I say.

Great! I'd like him to swing over and set up mine.. ;D

Jeff · March 17, 2006, 12:01:09 PM

I bet he do it for the gas money. :D

SwampDonkey · March 17, 2006, 12:09:32 PM

Good thing we got poor Chet to keep this dodgy outfit running even after all the abuse and fussin about. :D :D :D :D (tongue in cheek)

Has anyone out there ever had to replace bushings in thier grinding motor? Wood-Mizer only has brushes as parts, so I would like to source some parts before I tear it apart again. Its working, but it dont sound like it'll work good for verylong if you listen to that video clip.

Jeff,

I got a new motor when mine got too bad, $120 worth. I am going to tear the old one down and replace the bearings in it to keep as a spare. I am guessing it has ball bearings. but dont know for sure, I bet BDI will have what we need. If you want to wait a couple weeks till I get back from my trip out west, then I will tear mine down and take the bearings in to BDI and let you know what bearings they come up with for replacement. A good motor shop should be able to look up what bearings/bushings it uses, it is a Leeson motor.

I have found this little mod to work real nice. I was not happy about the coolant missing the wheel most of the time and not really cooling the blade. I cut a little bit of aluminum, and made an angle out of it, drilled and tapped a small hole in front of the blade holder to attach the aluminum on so that the water shoots back and climbs up the blade for a total flood cooling.

Also, If you want to use the sharpener in freezing weather, This mod helps out. I have a small bucket inside the cooler with heat tape wrapped around it, and the pump inside. the heat tape keeps everything from freezing, and I can sharpen in cold weather. You do have to knock off some Icicles when it gets down to about 10 degrees. but it keeps running.

The older black motor uses 2 small sealed bearings. NTN #Z809

gmmills · March 22, 2006, 08:09:54 PM

Jeff,

The sharpener motor bearings are NTN 608ZZ / 7.938. These bearings are not standard 608's. A standard 608 has a bore size of 8mm. A standard 608 will fit loose on the shaft, fall right on. The 608ZZ/ 7.938 has a bore size of 7.938 and will fit tightly on the shaft, press fit. They are special order at my local bearing dist. I usually order 4 at a time to keep a couple in inventory.

It looks like you have the old style motor . If you order a brush set from WM make sure you tell them you need a brush set for an earlier style motor. They are different than the current style motor brushes

chet · March 22, 2006, 08:24:50 PM

608Z upside down is Z809, who'd a thunk :D

Jeff · March 22, 2006, 08:32:11 PM

Do you think NAPA?

mometal77 · March 22, 2006, 09:14:55 PM

Dang jeff would love too introduce you all too hardware sales here. Even in the neighboring town we have grizzley corporate here. Lots of tools. Those parts you need are easy to get. Further note that powder coating is pretty neat stuff. Expensive but well worth it in the end.

gmmills · March 22, 2006, 09:15:46 PM

I purchased mine from Applied Industrial Technologies. They have a local branch store in town. I think you would be able to find them at any commercial based bearing distributor.

chet · March 22, 2006, 09:22:41 PM

My sources are showing a price of $10 each. Is that about what you got them for?

Tom · March 22, 2006, 09:25:20 PM

Ten Dollars for a little bearing? Sheesh!!

chet · March 22, 2006, 09:35:35 PM

My catalogs show the standard bearing costing about 3 bucks, but dat same bearing with the under size bore is a little over 10 bucks. :-\

gmmills · March 22, 2006, 10:13:41 PM

$20 for a pair of bearings vs $120 for a new motor. The bearings still seem to be an economical choice in my book.

isawlogs · March 22, 2006, 10:16:07 PM

Is that motor the same one as the up down on the mill ???

Dana · March 23, 2006, 07:43:12 AM

I have the same woodmizer sharpener/setter like the one Elly had listed for sale. I have never used mine, because it looks difficult to set up. Norwood offers one that uses a Dremmel for the motor. I have been thinking of buying one. Anyone have some advise on which way to go?

Tom · March 23, 2006, 08:03:28 AM

Yes. I have an opinion. :D

Set the woodmizer sharpener up and learn to use it. It isn't that difficult. Sharpening is a finesse' thing regardless of what you use. You already have one of the best little sharpeners available.
