Hobart 1512 Grinding Attachment gummed up-RESOLVED

[voyager 663rd]

I wanted to try sharpening the blade (I have the grinding attachment--probably worth more than the machine from what I've read) but the stones really do not want to rotate freely.

1)Are they supposed to rotate freely or are they supposed to resist rotation when placed against the spinning blade?

I didn't want to try sharpening because of this resistance.

I would think 'yes' so my primary question is: what is the best/safest way to clean them? I'm guessing they are gummed up with old grease. They come off (screw) really easily but the axles seem to be "attached for life".

Thanks for any tips.

They really should not spin freely necessarily. They need to spin but they don’t need to spin the same RPM of the blade. Are they spinning but just slow? If so that’s ok.

Boy, that's really a subjective question. For example turning by hand: they do require quite a bit of force to rotate (ie they will not spin on their own after giving a "push" so to speak like you would expect for example, a race on an axle would just spin and spin).

If I were to guess: if pressed against the spinning blade, you would have to press them really hard to get them to rotate, otherwise I believe they would stay stationary against the spinning blade and the stone would get a flat spot.

If I were to clean them (soap and water), I think there would be no way I could re-grease them. Maybe mineral oil that I use as a final cleaning step might work it's way in. Dunno.

You want the stones to turn while sharpening, but not exactly spin.

The drag or lack of spinning free is how the stone works the blade, but the stone does need to spin a little. This process takes seconds, not minutes, so the idea is to touch the stones to the blade briefly and just touch up the edge. Pretty short process.

Thanks for that. I still need to free up one of the two stones a lot more though as it is much harder to rotate than the other.

I'll keep at it

Well, thanks to SmokinEdge for your tips.

I've got food grade lube that I use for 'wipe downs' but hadn't thought to use that to use on the stone "axles".

Got one moving (with slight resistance) which I think is perfect. The other wheel is still resisting my lube efforts BUT will keep at it.

Consider this resolved

Just an update: mineral oil added but the other axle is still stiff. So I GENTLY took a heat gun to the barrel and it's freeing it up.

Now: heat turn and mineral oil. heat turn and mineral oil. Rinse and repeat.

But for how this is turning out, I've got a feeling that grease is never going to "leave the building". Might have to heat this up on the slicer and sharpen the blade while the barrel is still warm.

Either way, this will work.
