how about a short, well maybe not to short "How to make a Knob" for your jigs and hold downs.
start by making counterbore with a forstner bit.
with a holesaw, I follow the same center and cut the knob.
had several made.
I then enlarge the hole with a 5/16" bit to accept the T-nut.

Re: How To: make Knobs for jigs and hold-downs
with a light tap on the T-nut, I marked the mounting location.
which I pre-drill with a 1/16" bit to avoid cracking.
I screwed the bolt with a nut and washer into the opposite side of the T-nut.
just tighten the nut and the t-nut secures itself in place.

I later applied contact cement on both the knob sides and some 150 grit sandpaper.
once the contact cement is dry or no longer tacky, its time to put the sandpaper on.
everything in place.
and now usable..
I hope it helps some...

Re: How To: make Knobs for jigs and hold-downs
just to add what I think could help in getting the t-nut's teeth bite in is to use, say a wing-nut.
screw the bolt into the t-nut, ready to bite into the wood, then use the wing-nut to push the t-nut and make it bite the wood. this saves you from marking and pre-drilling where the teeth are supposed to bite in. works when I'm working with mdf. can't guarantee with other type of material though. hehe. disclaimer baga. 😉
Safety first - always wear face/eye/ear/hand protection as a minimum.
Re: How To: make Knobs for jigs and hold-downs
MDF is a very soft material that will accept the T-nut without problems. Hardwood will tend to crack in two if not pre drilled.

That is how I make knobs for my audio equipment. My problem is how to tighten the knob on the shaft. I tried a set screw but the screw doesn't hold. Any other ideas?
Re: How To: make Knobs for jigs and hold-downs
How about using a spot of super glue? Should be strong enough for regular use but should be easy enough to pry off with a screwdriver if need be.
