Deck builders typically use a lot of 4-by framing, but unfortunately a standard-sized 7 1/4-inch circular saw can't cut through a 4-by stock in a single pass. That's why Big Foot Tools invented its Big Foot saw adapter kits several years ago. Available to fit Bosch's 1677M and various versions of Skilsaw's model 77 wormdrive saws, the $229 (MSRP) kits have all the pieces needed to transform the 7 1/4-inch saw into a 10 1/4-inch saw, including a 36-tooth Big Foot blade, upper and lower blade guards, a shoe, and the various fasteners needed to make the conversion. The key parts are made of magnesium, and afterwards the saw will have a 3 7/8-inch depth of cut at 90 degrees and a 2 3/4-inch depth of cut at 45 degrees. The process isn't rocket science, but there are a couple of steps that are a little tricky, so now Big Foot has put together a pair of Youtube videos that provide easy-to-follow instructions.
