To save on expensive solvent, try this when cleaning up brushes. Find two cans with plastic lids, one can smaller and one larger. Pour the proper solvent in the smaller can to clean the brush. After cleaning, pour the used solvent into the larger can. The sediments will settle out in a day or two so you can reuse the clear solvent that will remain on top.
If you have a small air compressor or other machine in your workshop that vibrates, you can dampen it by putting special foot pads of corrugated cardboard squares under each of the legs. Make the pads about 2 in. thick by gluing several squares together. Glue so the corrugation of one piece lies at right angles to that of the next square of cardboard.
