Topic tags/keywords: corner cabinet window seat angle how 48 degree tip question resource

I am building a strange corner cabinet for a window seat.
The base is 21 11/16 across the front, 4.5 inch deep on the left and 24 on the right. Both the left and right side have to be cut at an angle so the back with fit on, 1/2 back screwed and glued. How do you cut a 48-degree angle on the vertical side of cab walls? Hope this makes sense to someone.

Could’nt you set your TS blade to the proper angle and rip the sides?

Gene, I guess he can only set his blade to 45-46 degree at most
If I understand it correctly, I’d fix a thin plank on the table, parallel to the blade, 50-60 cm apart.
Then I’d cut a piece of scrap panel. This panel lies on the table near the blade, and on the plank on the other side; therefore the cut will have an angle, say 10,23° or 8,7548°, I mean it’s not important. You have to measure it and to subtract it from 48°. Then set the blade to this difference and cut your panel, it will have 48 degree obviously.

In this case, I use to old style my father told me….. Cut 45 degrees on both and and clamped them together to form 90. Obviously a 6 degree offset will be present… Just saw it in the middle to make a perfect fit. this may take two times sawing depending on the kerf of the saw to cut the 6 degree offset. This is exactly the technique used for exact fitting of miterred frames where you saw those corners to have a perfect fit.

If I understand correctly, you could use a router and a straight edge clamped on the material at 48°.

Or, when in doubt, get out the hand plane.
