I have trying to find cheap inserts for my dog holes but dang they are relativly expensive when you need several of them. So, I found something a dog hole clamp that I really liked that was not plastic; however, they were rather expensive (Veritas Clamps) at ~45 bucks a pair.
Well I am a cheap skate so no way in the world I was going to pay that so I decided to make my own. I had a lot of the equipment already like a tap and die set and the drill press which makes it a thousand time easier to drill a hole in any round what-sa-ma-doodle. So I got 6 bucks worth of steel and I made 6 of them, they are not complete yet but the hard part is done. I am making the clamp end out of metal with holes to attach shaped ends so I have clamp shaped piece more easily.
While I am making metal ends for this I am making the top part of some T shaped dogs while I am at it.
Hear lately I have been doing just as much metal work as I have wood to just some some money. If I had purchased 6 clamp dog that would have been about 125 bucks but for 6 bucks, time, and a thing of 3 dollar cutting fluid I can make 6 clamp dogs and about 12 T Dogs with the equipment I already have. They are not as “fancy” as the factory ones but they are just as or more functional.
It is funny; however, now that I think about it… metal is so much cheaper than wood.
Oh and one more thing… I did the theads in 1/4-20 which matching all my jig knobs and bolts so I could use the pieces to make something more elaborate should I need them to make a jig.
