MM 20 lower guide undersize
I have a MM 20 that I bought at about the same time as the OP. It has the same guides. I haven't used the saw much and mostly with a 1/2" blade. Recently I tried a 1" blade and the lower guide will not adjust far enough forward. I checked the Carter site and the lower guide is designed for 3/4" blade max. When I first got the saw I questioned the rep that the top one is only for 1 1/4" blade (didn't notice the bottom was different) and the saw is advertised capable of using a 1 1/2" blade. He said that it was a typo and most only use a 1" blade, however, they still advertise 1 1/2". Along with feeling deceived I am concerned about how safe it is to run larger blades on the saw. I have checked with Carter and they don't recommend using larger than a 3/4" blade. After the amount of money that I paid for this saw I am rather disgusted at the prospect of spending several hundred dollars to get the saw to operate as intended. Do other owners of this saw have any problems using wide blades on their saw? Perhaps it doesn't make much difference. I am happy with the saw, but think I was hoodwinked on the guides/sawing capacity.
