I have an 7″ economy quick release vise from Woodcraft. Sometimes when I tighten down on a piece of wood, I can see the quick release lever moving and then eventually slip and the the vise disengages. It doesn’t do this all of the time, but whenever I put certain pieces in the vise it will not hold on. Does anyone know what is causing this to happen? Does anyone know how to fix this? Buying a new vise is out of the question as I am in college and already spending 50-75% of my income on tools and wood.

The quick release economy vise is not necessarily well-made as you know. In order for a vise to grip wood porperly, it should have a 2* to 3* degree cant at the very top on the closing jaw. The top of the outer jaw should touch the stock first. All good vises do this. I just built two for my new work-bench and beveled the front jaw for 3 degrees. This gives a more sure-fire death grip.
Check the jaw of your vise to see if you have any cant. If the quick release lever is defective and just slipping free, see if WoodCraft will replace it. Check the Acme screw to see if there is excessive wear or strip. Keep in mind you have a under $20 vise crafted by professionals in China. Professionals in China are not necessarily as professional as professionals in some other un-disclosed areas. ha..ha..
As soon as you graduate and get a job offer, consider a new vise. You can get good German hardware at WoodCraft or Highland Hardware and built a good vise for a small amount more than you paid. E-mail me your address and I will send you a Columibian 6". No quick realease, but it holds.
Good luck...

If it only slips in a certain position it could be something as simple as some glue or other debris on the screw. If the problem turns out to be a bad spot in the screw you can skip over that section of the screw by adding an extra piece of wood when clamping in that area. Also check out how the quick release is connected. Sometimes a pin or set screw pops out and will hit the screw and release. The difference between a quality screw and a cheap knock off is substantial. One of the reasons better vices cost more.
