I have recently bought a micro jig gripper for small cuts on the table saw and re-sawing. It was not a cheap push block and not first on my list, but I like my fingers and want to be as safe as I can. The system works well and will keep you very safe, but mine does not seem to grip. It seems to slip forward on the wood when I am pushing a piece through the table saw. If I push down hard with both hands on the back end it seems to work but that shifts my weight and creates a very unsafe working position. I have tried cleaning off the saw dust every time and changing where I put pressure on the block and nothing has worked. I shouldn't have to work extra hard for a push block to push. Has anybody else found this about the gripper? Does anybody know of a way to make my gripper grip?
