When you cut longer pieces, miter saws are best used with supports on both sides. One way is to cut in a drop-down section into a bench for the saw. Another is to build up raised supports on both sides of the saw on top of the bench. An upright along the back of the supports will let you use a stop block for repetitive cuts.
Engine grime can be difficult to wash off of your hands. If you don’t have a hand cleaner handy, your kitchen cupboard probably contains a solution. Reach for either a vegetable or olive cooking oil and spread a dab over your hands. Rub your hands together, then wipe off with a paper towel. Cooking oils will also help remove oil-based paint from hands and arms.
