Dog Bone Knobs

Seems like I can never find a jig knob when I need one. I’m always robbing from one jig to use on another. I’ve seen others making their own knobs but most just seem too complicated to bother with. Today I was browsing Jay Bates website and watched his “Trash to Treasures” video. He described making simple knobs and had a very easy way to add a nut or bolt – no t-nuts!

So, about an hour later I had 23 new knobs. The only thing original (as far as I know) is the shape. I thought of making them rectangular instead of square like Jay did, then hit on the idea of just sanding a slight curve into the long sides on the oscillating sander. Thus was born the “Dog Bone Knob”.

Pic 1 – Sanding the curve with the big end of the Home Depot sander. A large drum sander would also work. You can also see the stepped hole. Small bore is sized for the bolt – 1/4th or 5/16th in my case. The large bore (drilled first with a forstner bit) is as close to the width of the bolt/nut that I had.
Pic 2 – Quickly rounding the corners.
Pic 3 – I placed a nut above the larger whole and screwed a bolt into it from the bottom. Just finger tightened it to keep the nut in place for the next step. Note the large whole in the scrap block below.
Pic 4 – With the bolt head in the large hole on the scrap block I just WHACKED the nut with a large hammer! One good lick drove it right into the knob. I’ve always used a chisel to carve out the nut shape but Jay’s tip saves loads of time there…thanks Jay.
Pic 5 – The nut is tightly seated in the knob. Now just remove the bolt.
Pic 6 – My collection of new knobs. They can also be used on a bolt. I made 18 from 3/4” Oak Plywood and 5 from solid Oak.

I didn’t measure anything or make any patterns. I guess they’re about 2-1/4” by 1-1/4” but certainly could be any size you like. I may even put some poly on them. I’ll never buy another knob!

Great idea. I have done similar knobs in a hurry for a project late at night. You can’t beat it. Good idea to have some extras.

Nice easy knobs! I do the nut like this sometimes also. I usually mix a dab of epoxy to put on two or three sides to keep the nut in or mount a small metal or 1/8” hardboard plate over it to keep it captive in the knob, just takes another minute or two.

drbyte, I had considered a couple of drops of ca glue. I’ll see how they hold up.
