How do you .....????

[Charlie Woody]

I need to cut a piece of oak veneered mdf at an angle of 132 degrees. So 180 - 132 = 48, but circular saw and table saw only tilt to 45 degrees.

Does anybody know of a workaround for this please?

Double stick a wee shim/ packer to your table saw to give you what you need maybe two or three mm

Can you not set the saw to 42 degrees and turn the timber over. After all if you cut one angle to 45 degrees the other angle will be 135 degrees

Well that is what I was trying to explain in my original post. The desired angle is 132, if I turn the mdf over I need to set the saw to 48, but the max tilt is 45! Not sure where your 42 comes from as 180 - 42 = 138, not 132?

What size is the board finished?

thinking out loud - probably wont work, but - can you cut a 45 deg 'wedge' to fix to the base of the saw then tilt the saw the extra few degrees???

You make a sledge that is wedge shaped with an appropriate angle, say 45 degrees, you lay your MDY on the sledge, set the saw and pass through. Ensure that the sledge has provision to properly clamp down the MDF and preferably runs in the mitre grooves. At a pinch you can run it against the fence, but only if the MDF sheet is small and you can handle it safely.

Such a sledge is very useful for achieving angles lower than 45 degrees and allows any angle to be cut safely.

For inspiration of sledge design look up the USA design of cross cut sledges.

I was going to say make a prop of some kind to tilt the board vertically altering the angle of attack, but the above does this better and safer - if made with an adjustable angle it could be a very handy jig.

The 42 degree angle is set from the vertical not the horizontal. therefore if you angle the blade to 42 degrees from the vertical on the scale on your saw then the resulting angle on the opposite side has to be 132

Not in the workshop but think it is 1500 x 750 x 19 mm - why?

Mark it cut most of the waste off on the table saw then plane to the line with a nice sharp plane.

Hi

I did as you suggested and it worked a treat (after a little playing around to set the 42 angle accurately), so thank you very much for the very helpful response. Am I correct in thinking that you worked out the 42 as follows, 90 - 48 = 42? Just so I know for future reference so I don't have to bother everyone again!

Another option would of been to clamp an upright to your rip fence then pass the timber on end over the saw. That's why I asked how large the board was, not really practical in this instance but it works for small panels.
