Max, what grit do you use for lam grinding?

I want to jump into one of those but not until I find an adequate motor.   What do you use with yours?

The use of the hand drill as shown on their website looks kinda iffy.

That "Hog" looks like an awesome little machine. Appears solid and simple. If I was in the market for a mini grinder, I would be all over that thing.

It being aluminum, I would imagine someone with a hacksaw, drill press and a lot of patience could fabricate a reasonable version.

I have used 60 and 80 grit don't use a drill Motor, for a motor I had a old fan motor for mine


Flem you can't use a hacksaw and a drill press to make it

I get that, might need belt grinder also.  I wasn't thinking about replicating the "Hog", more like a functional version using similar materials and construction. I always figure aluminum is not too much harder to work than wood.

I have acquired a small wood lathe to use and found a foot long piece of 3" sch 40 Aluminum pipe.

I've been using Red Label Zirconium, 80 grit.

the zircromium seems like might be worth the extra expense.

what weights backings  seem to work best for lams?   cloth or paper?

I use the "3M Sand paper, last 10 times longer" for the Hog
For my baby drum sander I use what is recommended by Grizzly for glue on type

That aluminum pipe should make a nice drum Zirconium is definitely worth the money. Cloth backed for a drum. Funny thing, aluminum oxide grinds epoxy better than zirconium and zirconium is superior on wood.
I would recommend buying the best quality and largest diameter shaft and bearings you can afford. You could construct the most perfect drum, but if its riding on a marginal shaft or bearings, you will never be happy with it.

thanks Flem, that helps with the grit selection. No shaft on the lam grinder, just need a hub for the tailstock live center on the lathe, and a table of sorts to set on the bed. the lathe has this funky 4 jaw that works like a 3 jaw, but I think it will do OK for this application.

No shaft? How are you planning on mounting the drum?
