I was hoping that one of you experienced builders would help with my problem. What kind of blade do you use to cut v-slot rail so you get nice clean cuts? I have a 10" cutoff saw with a 5/8" arbor. I have used a metal blade to cut aluminum before and it makes a mess of it. I noticed in the Ox video that the cuts on the v-slot are clean and straight. Any help would be greatly appreciated. I'm holding up cutting my v-slot until I get an answer. Thanks for your help.
