The DIY homemade circle center finder tool shown in this video only took a few minutes to make and cost me nothing in terms of out-of-pocket funds.

I have several of the small plastic speed squares around the shop, so I sacrificed one of them for this project. I had some scrap ¾” birch plywood, and plenty of #8 x ¾” stainless steel, flathead, screws on hand. This handy tool would still be quite inexpensive if I had to buy the materials though, and well worth it!

Materials:

(1) 8” x 8” square piece of ¾” birch plywood

(1) small plastic speed square

(3) ¼” #8 x ¾ stainless steel flathead sheet metal screws

Actual time to make: About 20 minutes.
