Noticed my table saw blade mechanism was harder than normal to lower today, like I was cranking through resistance. Looked underneath it and saw a lot of sawdust buildup on the mechanisms. I’m thinking this is what I felt, the gears cranking through excess caked on dust. So I’m going to clean all this off and see if it helps. My question is what do I lubricate the gears with? Do I use anything at all? It seems this will just make dust stick to it even more.
