# How to cut tall baseboard on a miter saw on the flat with an angle greater than 45 degrees?

I have some 11" tall baseboard that I've salvaged from my house. I need to cut a number of outside corner miters where the angle of the miter cut is greater than 45 degrees. The corner is approximately 88 degrees. So the miter cut needs to be at 46 degrees.

Since the baseboard is taller than the miter fence, I cannot make the cut with the baseboard vertical. So the cut needs to be made with baseboard on the flat (on the bed of the miter saw).

Unfortunately, the miter saw can only bevel up to 45 degrees. How can I make these cuts?

Also, cutting on a table saw is not an option due to the length of the baseboard

• Is this a sliding miter saw? – Jim Stewart Oct 13 '17 at 15:14
• It is not. It is a 12" miter saw. But, I can make the full cut on the flat if I put a piece of 3/4" plywood on the bed to raise work piece. – awarmack Oct 13 '17 at 15:25
• Shouldn't the angles be 1/2 of 88 deg so 44 deg each? I guess you are taking the angles the way they are marked on the miter saw (angle from 90 deg)> Is this a double bevel miter saw? – Jim Stewart Oct 13 '17 at 15:37
• Per geometry, if you raise the edge of the work piece that you're cutting towards by 1 degree, the resulting cut angle will be 1 degree shallower. I haven't actually done it so I'll just leave this as a comment. – Robert Nubel Oct 13 '17 at 15:42
• I was thinking the same thing as @Robert Nubel: raising the end of the 3/4" plywood by a few degrees should put the bevel in range. – Jim Stewart Oct 13 '17 at 15:54
