Lam feed direction

[monterey]

For those with experience in grinding lams.

I'm working on a final design of a lam grinder for a rigid oscillating sander.  So far the idea has been towards feeding with the direction of the sander, but am having second thoughts.

Which "way" should I go?

I think with the direction you will have a lam launcher, you need pull them opposite of the direction of the rotation of the sand paper

Against.... like any other woodworking tool.

OK, so it seems like the lams should be drawn against the rotation with the operator standing upwind of the direction?

LOL,  my first and only attempt at making a lam grinder was a trip. And after it yanked the first board out of my hand and nearly drove it through the wall with the sound of a 12 gauge shotgun going off, I pulled the plug on it. LOL

I've got my ridgid set up to grind lams by feeding into the rotation. Just be sure you don't try to take too big of a cut. Also it works better with coarse grit. I use 36 grit shopsmith belts from Lowes. They are aggressive and last a long time

Good advice from Ben, The rigid sander is underpowered and can easily be choked down to the point the motor gives up the ghost.

Tip: if you grind a lot of glass, be sure to blow out the motor afterwards with compressed air. I have burned out the motor on two of these sanders, so I keep a spare on hand.
