The dawn quick release woodworking vice vice has a "square" thread, and have had no problems with the vice after that. Thanks for the response LanceC Was thinking along the same lines. May not post to Taiwan - Read item description or contact seller for postage options. I have two 'vintage' DAWN woodworking vices. It's not a manufacturing defect - it happens to both yours, and there's a good chance that it happens to others when used in the dawn quick release woodworking vice way. This item may be a floor model or store return that has been used. The item may have some signs of cosmetic wear, but is fully operational and functions as intended.

Not something one would expect to do all the time. Still don't under stand why it operates as expected clamping on one side but not the other! Managed to uplod a very average video of the issue.

The reason it happens pronounced on one side is because the mechanism isn't symetrical. It's not a manufacturing defect - it happens to both yours, and there's a good chance that it happens to others when used in the same way. A manufacturing defect is more likely to show in just one of your examples, but this is a pretty clear demonstration that they were manufactured perfectly - perfectly the same that is It really just means you're using it outside the expected parameters it was designed within.

The video, besides it's average quality and poor production values haha, sorry, just a joke , oh and that annoying black bar popping up, does show the torsion that is caused when you try to lock down on one side of the jaw. Is it a poor design? Is it abuse of a relatively lightweight device, possibly. Can you avoid it somewhat? Probably, by either not clamping on the extremities or by using a spacer block of scrap from the same timber, or by holding the QR lever to keep the teeth seated while applying the tension I don't have the answer for you but I watched these couple of videos of Record QR vices being pulled apart and reassembled and there might be something in there that points to the problem you are having.

Vid 1 Vid 2. Ha Ha Thanks Poundy Enjoyed your insightful musings into my problem and your constructive criticism as to my video producing prowess! Using free software to reduce a trillion megabyte video to something that the forum will accept!

Thanks for the advice though; your explanation makes perfect sense. A space block to even up the asymmetry seems a good idea. Thanks Treecycle Will definately check those vids out! It's called "racking" the vice. Tightening with the workpiece outside of the supports to the point it looses parallel. As mentioned by Poundy, the solution is to have piece of material to balance the other side. It's just part of the design of the tool. Apart from the wedge, you can buy a " Moxon " vice or a " Twin Screw " vice, both of which have the support bars wide apart to minimise "Racking".

Pat Work is a necessary evil to be avoided. Mark Twain. I have a No. I think the way I fixed it was to bend the tab holding down the flat bar in the middle. It has a screw through it and appears right in the centre of the screen in your video. Looking at yours I'd guess it has to be bent down thus limiting the sideways movement of the bar which is causing it to slip.

I ditched my quick release vices a long time ago. I looked at the problem and came up with the idea that a "butress" thread was the problem. The replacement vice has a "square" thread, and have had no problems with the vice after that. Sometimes in the daily challenges that life gives us, we miss what is really important I've got a dawn QR vise which used to slip too. I pulled the spring out which puts pressure on the QR lever and either over extended or loosened it, I forget which way was needed, which firmed up the lever pressure.

I don't get any slipping at all since then. I should note that I initially overdue it, and needed to swallow a can's worth of spinach in order to activate the QR lever.

When moving it to my new bench, I loosened the tension and it now functions nicely. Thanks Pat Maybe I need to expect less from my old man's tools or just consider the limitations of them. Hi Tccp I actually thought that too Neither seemed to help. No additional import charges at delivery!
