I have a chance to buy a nice Delta 31-260 sander. What do you guys like for a drum sander to make lams?

That 31-260 is a nice sander. You could do some major lam grinding with that dude in a hurry.

if you decide to go ahead with it, contact me and I'll get you set up with some taper sleds for it.

I use a jet 22-44 and that works great,you will love using the delta.

Here is a good source for rolls of sand paper
