1/8" blade.......3/4" radiused cuts?
whenever i need to use a blade smaller than 1/4" i`ll completely burry it in the guides......cool blocks will work well for this (they`ll sand back smooth when you`re done) or make sacrificial ones from wood. the thrust bearings are totally removed from the equation.
the way i set the blocks is to jamb them into the running blade so the teeth cut their own path in the blocks then lock down the blocks.
sam blasco showed a method tought to him by his grandfather that accomplishes the same thing using euro-style guides but i don`t have the link handy
