I needed a large radius circle for a project I was building, but I didn't have anything large enough to use as a template (bucket lids and whatnots) so I built a simple wooden compass.
I can also use it to draw pretty pictures....
Wood - In this case a 1 1/2 square piece of scrap cherry about 16" long
Hardware: 5/16 bolt, a washer and a wing nut
Compass point: A drywall screw
Drawing point: Small pencil (like from mini golf places)
Finish: Shellac in a ranch dressing bottle.
Step 1: Cutting the Pieces
As stated I had a scrap piece of cherry in the shop from another project so I used it.
I ripped it on the table saw down the middle.
That gave me 2 halves: 3/4" x 1 1/2" x 16"
