I have had several requests for dimensioned drawings for the pool cue stand........The model is in the Sketchup warehouse, but here are the key dimensioned drawings.........
When I made my cue stand, I probably printed out full-scale paper patterns from Sketchup.......and therefore did not have to do conventional layout, where you swing the arcs from a center point. I added this arc center dimension to the part I forgot to show it on.
Many years ago, I bought a simple pair of items that clamp onto a wood yardstick, to make circles. I just checked Amazon and was surprised to see they are now $30...........I think I gave less than $10 for mine many years ago.
There are many "poor mans" methods of making 1-time big arcs. Most of these involve using a scrap piece of wood, and inserting finishing nail(s) or a pencil to mark the radius's.
