Good day

If you remember the post “Triangle Copy and Past”
and “Triangle after copy and past”

I made bigger 45° triangle 20-11/16” x 20-11/16” x 29-1/8”

I used an Aluminum straight edge after checking with caliper that it has consistent width.

You can use even a plywood strip but it must be consistent in width all along.

You can stick the straight edge with Carpet tape (if it’s Aluminum like mine) or screw it (if its wooden or ply).

You can use any width of straight edge, depends by how much you want to “enlarge” the triangle (I used 3¼” wide).

The rest is very simple, you just chuck a bearing guided straight bit and “Copy” side after side.


Finished all 3 sides

Checking for 90° on a straight edge

This is my TS

Back to the router table with ¼” straight bit



I had enough plywood to make 2 of them

The strip for the base was also made very consistent in width , then, I made a groove for the triangle and glue it with CA (super glue).


Thank you

Niki Looks like all of the pictures are gone. Do you still have them available, somewhere?

Thank you Karson

When I lost my Photobucket account, some posts pictures also disappeared but, as I promised, I will re-load any post pics that will be requested.

Very nice “how-to.”

Have your say...
