Pete,

A couple of questions:

How is the sander holding up? The reason for the question is I have the same sander and set up a lam grinding jig similar to yours last spring. After about fifty lams the bearings on it developed a wobble and I wasn't able to get smooth lams anymore. I replaced the bearing but it still wobbles too much to use for lams.

The biggest problem I found (when the sander was working properly) was getting a constant feed when pushing the lams through the jig. Any deviation in the push speed and the lams got low or high spots. Have you had that problem?

I had some coated MDF (the type used for shelving and cabinets) left over from another project and used it for my jig; It worked good and provided a square, slick surface. It is set up with adjustable wing nuts and a dial micrometer that allowed really fine adjustments without any guessing. If I get a chance, I will take a picture this weekend and post it.

--------------------
The broadhead used, regardless of how sharp, is nowhere as important as being able to place it in the correct spot.

Walt,

I have only made 8 sets of lams so far. Like you said the speed at which the lam is fed is critical for controlling the depth of the cuts. Another thing that I have found is how much wood you removing in one pass. I only remove a little bit of wood each pass and I feed the lam through the grinder 3-4 times each setting keeping a light touch. This makes it easier to have that desired consistent feed speed...

Thanks for the heads up on the bearing issues. I will keep that in mind!!! Has anyone else experienced this? I am surprised that after re bearing you did not get the same accuracy back. What type of bearing did you replace it with? Do you remember?

Pete, I replaced the bearings with new ones from Rigid.

Walt,

I am really glad you pointed out the bearing problem. Do you have any idea why the wobble remains? Was the bearing a tough install? I am really going to look this rig over and see what I come up with. No reason to re invent a wheel that doesn't work!I do look forward to seeing yours.
