Topic tags/keywords: tip shop knobs

I recently saw this some where.It may have been here on LJ’s. But I thought it was a grand idea, especially when I found that I had no 1/4 20 knobs for a jig I am making.

Rather than wait a week to ten days on the pony express, I asked my wife to keep an eye out for golf balls when she was checking out the thrift stores.

All you need is the golf balls and what ever size inserts you are using for your carriage bolts or t-bolts. Drill the hole almost all the way through, install the insert and presto you are in business. I did find that on a couple of the balls, I had to glue the inserts in with Gorilla glue. They are made different inside I guess, but as cheap as the golf balls are, who cares.

The dimples give excellent grip and I think they are neat too.

That is a great idea, enlighten me though, are you talking about threaded inserts for ply? The ones I have are 1/2” . Are these big enough?

Great idea, I stocked up on various length and threads of inserts before I retired from Fasteners, and have
extra golf balls picked up while hiking (yes I know I am a packrat), so this idea is perfect for me, and I just
happen to need a few jigs. Thank you for sharing.

Rand, Good idea!

Have any trouble drilling it?
What kind of bit did you use?


Thank you.

@ nailbanger2, yes. I use the ones McFeely’s sells, but some golf balls hold tight while others need Gorilla glue to keep them in when you loosen then to make an adjustment.

@ Joe, They are easy to drill. Just drill a 3/4 hole with a spade bit about 3/8 deep, center the board under the drill, pop in a ball and use whatever size bit your insert calls for and drill away. You need to drill almost all the way through to allow the extra threads on the bolt some where to go.

@ purplev, Don’t all woodworkers keep inserts in the shop? lol

If you or your neighbour is throwing out any old pre fab computer desks or furniture check for the threaded inserts that they use in them . i picked up 44 inserts in one desk . Most are 1/4×20 but some times metric .
pick them up at home depot or lowes if you have no luck dumpster diving.

@andysden, Great idea, I have an old IKEA computer desk in the burn pile. I better go check it out.

@ David, I have fairly large hands and arthritis as well, and I have no problem turning these tight. I think it is the rubber or whatever the outer layer is and the dimples that give you great gripping power on them.
Of course,if you have hands like King Kong, then we have a whole new area to investigate. lol

Very good idea, Rand. They’re not all that bad looking either.
