I wanted to make hold down claps for my cheap T-Track. I wanted four to keep various modular tools in place (Jigsaw table, drill press, etc). I will also be able to use to lock pieces of stock in place. Two smaller clamps will be used to keep stock tight on the drill press.
- Multiplex (scraps in my case)
- Metal Pipe
- M8 Bolt
- M8 Washers
- M8 Wingnut
- M8 Eye Nut
- Wax or spray finish
- Belt sander
- Jig Saw
Before setting out to design clamps of my own, I browsed around on the internet for a while. I found various examples, the wooden of which appealed most to me. For the larger ones, I took two circles (circumferences of tape rolls) and spaced them the centers about 15 centimeters apart. This was all done solely on feeling.
Then came the sawing. I am ever so glad to have bought a blade specially made cutting hardwood. I decided to make the clamps with two parts hardwood on the sides and pine in the middle.
After cutting all the parts, I sawed out one groove out of the middle of the pine, glued the thing together and sculpted with the belt sander. I took a bit of aluminum pipe, drilled a hole in it and cut the bit with the hole off.
I grabbed the bolt, the eye nut, the wing nut and the washers. I covered the wooden part in beeswax. For extra grip, I added small patches of an old bike tire that had died on me.
Putting the whole thing together resulted in a magnificently working clamp. Mind you, the T-track I have is a really cheap solution, hence the use of the wing nut and the amount of bowing.
