DIY Tip of the Day: Jacked-Up Outfeed Roller. To assemble an adjustable outfeed roller for your table saw and other power tools, drill holes in the base of a scissors jack and bolt it to a sturdy sawhorse. Bolt a bracketed roller (about $20 at woodworking stores) to the top of the jack. For faster adjustments, chuck a screw hook into a cordless drill (photo) and insert it in the jack’s drive hole.
