I have a grizzly g8691 lathe. It seems to work OK but at higher speeds it produces a knocking noise. I'm going to try and take the cover off this weekend if I get the time but I'm wondering what the noise could be?
The question is can I fix it? I don't want to deal with grizzly because the lathe is out of warrenty. My Nova DVR should arrive soon so the question becomes if I can sell the lathe or just toss it.
Does your Grizzly have a mechanical variable drive? If so when did you replace the drive belt. Removing the cover and having a look, when the lathe is stop, could quickly reveal if the drive belt if wearing out. Also make sure that the set screws on the pulley are not loose and the square keys are well set in their slots. Let us of your findings under the cover.
Often knocking noises indicate a loose pulley or other item. Billh
With the new lathe coming in, the old one is not much of a concern for now. However, you may already have a buyer for the grizzly as is. Or you may decide to keep it as a sanding station or else. While the grizzly is at a stop position I would investigate under the hood. The last time I had knocking on my first lathe It was caused by a loose set screw on the Aluminum pulley. I ended up drilling and tapping with an American size a tad larger. The North American set screw has a better cup end and thread tolerances. Then after that I replaced the drive belt with an North American made one which is of a much better quality. Enjoy your new lathe.
I don't know if I'd go to as much length to fix it as you mention. I don't have a buyer as yet but I've sold stuff locally on the net putting a BO for best offer on the posting and it usually sells. I just don't like selling or giving something with a problem that I can't either fix or tell the buyer how to fix.

Reyd was looking for a lathe a while back. If you were going to give it to someone, why not him? That would be a very noble and very cool thing to do...

I still need to look at the lathe maybe this weekend to see what is wrong with it.

I think you're looking to a valve job on it -- perhaps a main bearing. Have you tried a compression check? *G*
no but it growled when I tried to open the hood!-)
with the number of people that seem to be interested in this beast I sure hope the problem is easily fixable
I do have the crud. My wife would not even let me go out and shovel a couple >I think you're looking to a valve job on it -- perhaps a main bearing. Have
Hi William, I'm sorry that you are ailing. Try to supress your cough or not cough very loud. EPA monitors might pick up the melody, raid your dusty shop and confiscate your new toy. Maybe they can be bribed with the Grizzly. Take care. Arch
Fortiter,

I finally got a chance to look at the grizzly lathe on Sunday.
It had both a loose belt and pully.
The grizzly lathe is now for sale. It is a good learning lathe. I learned to turn on it. I learned to sharpen my chisels so I would not bog down on the grizzly
