Being a thrifty woodworker, I like to save on everything. Here’s how I save by making my own shopmade jig knobs with scrapwood and 1/4” T-nuts.
Using a compass I roughly draw the shanks on a 3/4’’-thick scrapwood then I drill 1/16”-deep recesses for the head of the T-nuts using a 3/4” spade bit.
With a 1-1/4” hole saw I drill the shanks part way from one side and part way from the other side. Note that the centre holes left by the spade bit give perfect starting points for the hole saw.
Then I drill a 5/16” through hole in each shank for the T-nut centre barrels.
After making 2” square blocks for the handles, I drill a 1/4” centre hole in each one. Then I chamfer all edges at the disk sander, taking the time to roundover the corners to get comfortable knobs.
I spread a small bead of glue on the perimeter of each shank and clamp the handles to the shanks using a 1”-long 1/4” bolt, finger tighten only.
When the glue is dry, my knobs are ready to work, as seen on my shopmade horizontal router table height adjustment.
Such shopmade knobs can be made any sizes using according T-nuts and drilling appropriate recess diameters and depths.
