Wondering if anyone has a pattern for a shop made hold down clamp similar to this commercial model from Rockler:

I figure I can probably come up with something but thought it would be easier if someone already did the leg work :)

Also, does anyone have any suggestions for sourcing T-track bolts locally? This is what I’m looking for:

I know I could order from Rockler, but figured it’d be worth it to save the $7 shipping cost on an $8 order if I could get them locally.

Here is an idea for shop made;

You can use standard 5/16 bolts in most T-tracks.

Good Luck!

T track bolts are toilet bolts available at any hardware/big box store.You can get 1/4 or 5/16 in various lengths.

Here’s a pattern I like:

I also use toilet bolts.
Hope this helps!

Drew, such a nice clamp. Doesn’t seem right to have a plastic knob. :)

rance, I need to make some wood knobs, but the woodcraft knobs were only a buck each, so I figured they would be a good temporary fix so I can use the clamps until I get around to making a bunch of knobs

A Q&D (quick & dirty) solution is a piece of scrap hardwood: 1/2” x 1-1/2” x 6”. Drill a hole in the center for a T-bolt. Add 100 grit sandpaper to both ends with double-sticky carpet tape. To use the hold down, you will need a piece of stock under the free-end, to match the height of your work piece.

Not what you would call an elegant solution – but it’s easy to make when you need something quick. I made a couple for a dedicated jig and have since borrowed them for other temporary jigs!

Last, but not least, a tip for low cost knobs for your jigs – lawn mower replacement handle knobs. The bolt/thread size is 5/16”, and they generally cost less than $3 a pair.

Drew, I know it probably had to be done but seeing that gorgeous clamp over laminate is causing my neurons to fire abnormally. I really like the look of the trapped tapped bar. Fantastic idea that took quite a bit of work. I have a deep respect for all shop made tools.

Thanks for the comments and suggestions. Don, have you actually sourced these lawnmower knobs locally or is that just an idea that you had? I ask because I had a similar idea and found that nobody sells them. I haven’t checked a lawnmower repair place, but I checked all the big box stores and struck out. The closest place I’ve found is woodcraft, but it’s an hour drive for me. Last time I was there I bought 10 of ‘em and only have 3 or 4 unused so I’ll probably reload next time I’m in the area.

The best place I have found for T-Track is They use just common 1/4” hex head bolts or you can use Toilet bolts.
