What to do on a boring snowday

You lose a little with brazed parts but it's negligible when you figure in the dollar figure......You can compensate for mass as i did and plan to do by adding mass. This unit will likely do -70 ( being conservative ), my original design did about -65 had less mass and had a wider, very short pinned insert versus this design, It also lacked the base that I'm adding. A really good unit with DI can do like -90 or possibly lower.
