My first post here, and Im not sure if anyone has posted something similar in the past…but here goes.
First, I trace the knob template unto a piece of wood…
I then draw 3 lines from each of the 6 points that you see on the knob to find the center point.
I then use a 1/2 fostner bit to cut out where the 1/4-20 nut will fit into.
The next step is to use a hole saw to cut out knob. By keeping your piece secured to the drill press you are guaranteed that the hole for the nut and the outer cut will line up perfectly.
I then attach a fostner bit that will have the same radius as the knob, I secure the knob and drill out each section. This part takes some time since each time you have to release how you secure the nut to the drill press so you can rotate and align for the next cut…I use hold down clamps.
From smaller stock cut out part that will attach to the opposite side.[/COLOR][/B]
I used a drum sander on my drill press to sand the knobs before I glued them…also, to make sure the holes line up. run a 1/4 bolt thru the knob and the round piece to make sure they are aligned properly when glued.
