Circular Saw


Step 1

On the two 2x6 boards at 104-5/8", mark the angle cuts as shown and cut off with a miter saw or a circular saw.

NOTE: The 22-1/2 degree cut is measured as a angle off a square (90 degree) cut.  If using a miter saw, simply set the angle cut to 22-1/2 degrees and cut.

Step 2

Layout the two cut boards, so the 45 degree cuts match each other at the top as shown.

Use a pencil to trace the overlaps.

Step 3

Set the circular saw cutting depth to 3/4".

Clamp the boards to a stable surface.

Make cuts about 1/4" apart on the overlapping areas with the circular saw.

Break the pieces out and then use a chisel to remove excess.

Step 4

Lap the two pieces and test the fit.

You can proceed to the next step and apply a finish before final assembly, or you can attach the two pieces together now with 1-1/4" screws.

If you are planning to use the arch repeatedly, use 1-1/2" bolts and washers and nuts for easy assembly/disassembly.

Step 5

Screw the base pieces to the bottom of the arch with 2-1/2" screws.

Finishing Instructions
