Default An Issue With The MJ Gripper

First of all, I will be the first to say that it is never ever a good idea to say anything negative about a product that is not proven to be true. So I want to be very careful to not imply that that there is anything wrong with the Gripper, I just had an experience that I need to ask a question about, so here goes.

I only recently purchased the basic Gripper then got the upgrade kit, the 1/8" leg, and the bridge handle.

This morning I installed the 1/8" leg which does not measure.125", but rather .160". Well what to do, just give it a try and see what happens but to be safe I set the height of the blade to barely cut into the top surface of a workpiece. In this case the workpiece was a piece of scrap cedar about an inch thick. I set up for the cut as close as I could and made a cut. Sure enough the blade took off part of the rubber pad on the inside of the 1/8" leg by about 1/16" high on the inside surface of the leg. Since the blade was set very low the leg was not ruined.

The thickness of the piece that was cut off was .156", not .125". the part of leg that the blade took off off the bottom edge of the rubber pad ended up being .105". I had taken off .055" of the inside edge of the leg.

If I had backed the fence off far enough to not allow the blade to contact the leg, the piece that would have been cut off would have been over .200".

Did I do something wrong, or am I being to picking expecting the leg to allow cuts similar to what is advertised and shown in the demos????

Jerry,

I would talk to Micro Jig and see what they have to say.

Personally, If I were cutting 1/8 inch slices, I would cut them so they fall off on the outside of the blade.

But, if they advertise being able to do it, then see if they have any setup advice or any other comments.

Jerry...is it possible that the bottom of the 1/8" leg is angled away from the top where it's screwed to the body...? Meaning it might not be perpendicular to the table when it's against the fence ?

Doug,
Yeah, up until now I have done my thin cuts on the left side of the blade and using the Incra LS system this has worked well, yes you have to re-set the fence for each cut but that isn't much of a probem. I just thought that I'd try the Gripper with th narrow leg. And yes, I will talk to the factory to see what they say about it, but it sure does seem to me that the leg is to wide at .160".

Nick,

Sure is worth checking, but that won't account for the leg being what appears to be over size or what I think is over sized at .160" instead of something just under .125"

Kinda anxious to talk to the folks a the factory.

Guess I could just set the fence to 1/8" with the LS positioner and cut the leg to the lesser width after raising the blade to a height that would cut all the up the side of leg.

Jerry,
I checked my nominal 1/8" side with my digital caliper; it is consistently 0.1130".

I'm sure Jerry that if you were to post a few shots showing your exact setup, then the problem will be solved quickly.

I ordered everything via phone from Microjig, but this morning, for the life of me I can't even find their phone number so, for now anyway, I can't make an inquiry, maybe later when I have more time to mess with it.

It's not important anyway, I have gotten along without for quite some time, but am courous.

I'll try to get some photos a per Harry's suggestion.
