Using a standard circular saw or sabre saw, how do I rip a plank to get a lengthwise bevel gtr than 45 deg?
Question:My saws only cut bevels to 45 degrees (most only go that far). This is to cut a chine 3ft long which has to fit at an angle where two sheets of plywood meet.
Answers:
This one is tricky. The only way I know to do it is to turn the piece on edge. Then take the degree of bevel you want (ex. 55) and subtract it from 90 (ex. 90-55=35) So, you'd set your saw to 35 degrees and go for it.
Since it will have to be on edge, you will have little to no control of the saw freehand. You will almost certainly need to build a jig to aid you. Clamp the board in place, to a table or something similar. Place a board perpindicular to the piece you are cutting for your saw table to rest on, and secure it. Then take another piece to put on top of this piece for the rear of your saw table to ride against to give you a smooth, straight cut. Hope that makes sense.
Hmm, you can bevel the edge of a 2x4 on a tablesaw and screw it on a straight line into the plywood bevel edge down. You might need to screw a "guidefence" onto the flat edge of the 2x4. i'm not really sure what you are doing but you can try that if you understand what I'm talking about.
my circular saw will barely make it through a 2x4 at 45 degrees. dont know if it will cut all the way through at a steeper angle...
If you're able to cut from the back side of the board, its an easy solution. Simply cut the complimentary angle and turn your board over. If you make a 40 degree cut, your cut-off angle will be 50 degrees etc.
you could attache an angle cut piece of wood to the bottom of your saw guide plate.
