if the grizzly belt sander says a minimum thickness of 1/8"or .125 how do you do a lam at say .40 or.60 what is the correct way of doing it ?
You have to run it on a sled to get the thinner stuff, and actually, .125 is a little thin to run through by itself anyway. What you need to do is get a perfectly flat piece of hardwood, say oak, and run your lams on that. Just make sure you joint and plane the sled perfectly flat, as any undulations will cause your lam to be thick/thin in areas. The same idea works for tapers. Probably the easiest way is to order a couple taper lams like you want, and sandwich them between a couple pieces of perfectly flat hardwood, making a sled that has the exact rate of taper that you want.
Hope that made sense!
I have the Baby Drum Sander from Grizzly and have no problems getting my lams down to .040" without a sled.
Hope this helps.

Check with Kirk at "Big Foot" he sales sleds.
On my Griz widebelt, you can sand the conveyor belt.
I did grind the conveyor when I found the belt was thicker at the splice, it would grind lams .004 to .005 thinner at random. Drove me nuts for a while!
ok well thanks fellas i was just curious i assumed yall used a sled but i thought i would check
Only a sled for tapers, see no reason to on parallels!
