Installed the quick release a couple of months ago. Never thought it was worth the price but it was a gift. Now I know it is note worth the price. After 2 months of trying to figure out why the gears were always locking up I called Carter. Explained what was happening and was immediately told I had broken a gear and they would send me a repair kit for $45. I told them it was only 2 months old and this is when I found out it only has a 30 day warranty. I removed it from the BS took it apart and found none of the gears are broken. What I did find is the tolerance on the gears is so poor it is not surprising they become misaligned and lock up. I have a 14" Delta BS. This quick release is the model for this saw. There is a V groove in the top of the part which moves up and down. The tension rod on the Delta is beveled on the end but does not fit into the V groove. This adds to the movement problem which causes the gears to lock up. I gave up on the quick release and removed it from the BS.
Unfortunately this has not ended my problems. I am a retired mech. engr. and believed I understand how the BS works. I am not so sure now.
When I put everything back together I found a problem that is driving me nuts. When I turn the tension rod to increase tension the nut rises compressing the spring and moves the wheel up. I am using a 3/8" blade which was on the saw before the quick release and worked. The nut reaches the top of the threads in the rod and will not go any higher. The blade is no where close to having enough tension. How the heck is this possible?
