ArticleBuild a Filter Clamp: ProjectsWritten by John ArnoldPlate filtration systems are popular among home winemakers. These systems use disposable filter plates with a filter selectivity that usually ranges from 0.5–6.0 microns. The filter plates must be changed every so often, a tedious chore that involves removing several wing bolts, six in the case of the popular Ferrari-style filter, to replace the filters. Fortunately, there’s an easy solution that will allows you to change filter pads more quickly and with less effort — the clamp. After experimenting with various contraptions that would speed the process of filter changing, I have developed a simple clamp system. In my system, the bolts are removed from your plate filter and the entire unit is clamped between two boards, which hold it snugly in place. The following plans are based on a system that I have used with great success. To build this clamp, you will need to obtain the following materials: Two 12 by 12 by 5/8-inch pressed boards. (For best results use a board that will not easily absorb liquids.) Three 5-inch by 3/8-inch carriage bolts Two 3/8-inch regular nuts Three 3/8-inchAlready a member?
