I made these jig knobs using the cap of orange juice bottles and 15 mm/ 5/8” Baltic birch plywood and a !/4” carriage bolt with nut and washer .
I just could not throw the caps away as they provide such a good grip and provide a nice finish for the knob .
These will go on a jig I am working on .
Here are a few pictures of how I made the disc and marked out the saw cuts to match the fins inside the cap .

Draw the circle to the size of the inside of the cap and drill a 1/4” hole followed by cutting out the disc with band saw .Then it’s onto the disc sander and the precise disc sanding jig which I previously posted see link .
Onto marking the location of the fins by inserting the disc into the cap and giving it a tap with my little tapper mallet this will indent the plywood disc slightly ,mark the location with a pencil and cut the slots with the band saw .
Install the 1/4’ bolt nut and washer and drive the assembly into the cap ,I got a nice tight fit on all three and they work just great .
Save the caps it makes nice clean knobs and takes no time it all and the price is right as my tool shop want’s about $3.80 a piece for them now .

Another little reuse project .

Awesome!! with a 3yr old at home we go through a load of these bottles of juice and then some, your handy work makes me wonder why I never thought of this, now, this is recycling at its best. Super awesome idea, and you can bet that I will be making quite of these.

I like that idea of recycling what normally would be thrown away. I’m going to start saving caps from Orange Juice Bottle.

Thanks for that idea.

That’s the way to go ! I like it. You can’t trow away such good grip. I also like your precise disc sanding jig, which I favorite of course.
