Ok..so I’m going to try and better explain my clamp. First of all this is my prototype, first one built – not building it to make a really nice one – just seeing if it would work….that being said – anyone with any ideas to make it better would be welcome.
The movable jaw is cut as shown in the picture. The depth of the cut needs to be half of the 1×2 (maybe a TAD more – I’m talking like a 1/32 more) so when joined together, the 1×2 shaft will fit snugly between them (without a lot of give). When I made the cuts, I didnt do a lot of measuring – I just was fooling around to see if it would work like I thought it would. I made the first cut at a 90 degree and the 2nd cut at a 45 degree. I don’t think I should have made that 2nd cut quite at 45…maybe should have been a 30, or even less. These cuts need to be the EXACT width of the shaft (1×2) – if its not really snug (mine isn’t) it will not hold as well…. When the jaw is at a 90 degree with the shaft it is cinched into place, and when pivoted to the other degree (whatever you choose) you can freely move it up and down the shaft (mind out of the gutters please!!).
When clamping with it, you must have the pressure on the ends of the jaw – if its clamped too close to the shaft – it’ll just slide on you, and you won’t get a good clamp. The knob I made out of some scrap pine. I glued a bolt through the middle of it with some epoxy. The bolt is threaded through the stationary jaw with a threaded Tee Nut. The “wooden washer” on the end of the bolt does not work well, and needs to be done differently. It needs to rotate freely on the bolt so when tightening it doesn’t “walk” on you. I was thinking about sanding the end of the bolt flat, drilling a small hole down the center. Then put a nail through the “wooden washer” to go through that hole in the bolt – then it would rotate freely. Or you could take the “cheap” way out and buy the hardware that JohnnyW posted in my last post about this clamp :) that project is here
So there it is….Let me know what you guys think. If you build one, I would like to see it – or if you have any improvements on it, I’d like to hear them too!! Thanks everyone!!
