Circular Saw Cutting Guide Board
|How To Make
Use this skillsaw cutting guide board to make straight cuts with a skillsaw, use an eight footer to rip sheets of plywood lengthwise and a four footer to cut across the sheet.
Using a straight board tack it to a strip of at least 1/2" thick plywood with a factory edge so that a 5" strip is cut off, then cut a second strip 10" wide in the same manner, this strip does not need a factory edge.
Cut a notch for the clamps in each end of the 5" wide strip. Fasten the 5" wide strip on top of the 10" wide strip with the factory edge in the center of the 10" strip with glue and wood screws.
Position the base of your saw against the edge of "A" and cut through the entire length of "B".
How To Use
To use the guide line the edge of the wide board "B" with marks on sheet to be ripped, fasten both ends of guide with clamps, run saw along on top of "B" and against "A" to make cut.
To use the guide to rip a narrow board select a second board the same thickness as board being ripped, fasten this board to bottom of guide with double sided carpet tape. Lay a strip of carpet tape on board to be ripped and align guide with rip marks and press down.
Use the guide on top of some sacrifical material and set saw just deep enough to cut through the board.
A sheet of MDF is 1" wider and longer than a sheet of plywood, to make a guide long enough to work for both make the guides from MDF. Make sure the notches at the ends are deep enough to work on the narrower width of the plywood sheet.
