    I recently installed a 52 1/2 vise in my bench. When I pull the quick release lever and slide it back and forth, it doesn’t quite disengage enough and I can hear the mechanism bouncing over the teeth in the screw. It still works, it’s just not smooth.

    I tried putting some washers under the plate that the engagement mechanism drops down to when you pull the release lever to see if I could give it a bit more clearance, but it didn’t seem to help much. I’m wondering if there’s something else I can try. This is my first vise so I don’t have much knowledge about it and the instruction booklet didn’t offer any hints. My guess is the vise was from the late 70s early 80s based on the box, but I’m not sure how to tell. Basically a guy bought it years ago and then never used it. He couldn’t remember when he bought it.

    Thanks for any advice.

    Wow, so it’s basically an unused Record vise. Well, I don’t know anything about the Record QR mechanisms, but I’ve had great luck taking things apart, cleaning up and putting back together. Yours may not need any clean-up, but at least you would gain a some insight to the problem. Good luck.

    Only guessing, the spring may need attention.I know through experence, to get new one, you will need it custom made. Good news Spring making companys exist,and can make one, not to expensive. Maby attempt to put a small chook at one end, on the off chance it has weakend a little. Again I am not writing via known knowlage,just a thought, good luck,cheers Peter

    Than…..,
    Have a look at this thread, may give some direction.

    BTW, His problem is not enough tension on the spring and he should be testing by clamping the vise in the correct upright position to an over hanging plank, not upside down.
    My guess is that your lifting bar ( the long flat metal bar) is not properly engaging.
    Look at the last two closeups that he posted, showing the bar passing thru the split nut post.
    In the very last photo the “strap” that houses the split nut post and bar there is a tab on the right inside. The flat bar must be positioned as shown ( above the tab) *In this vise the tab is not punched into the strap but has been inserted into a hole and peened over. Hard to see if you don’t know it’s there.
    If the flat bar is on the other side of the tab, the bar wont be able to lift the split nut post correctly.

    Hope this helps.

    Thanks for all the posts. So I went and took a much closer look at it and figured out the issue. I took a short video so you can hear the noise:

    I also figured out a fix. I’ll post what I did, either for critique or posterity in case someone else runs into the issue.

    The chattering wasn’t being caused by the split nut (which I assume is the plate with the threads that is moved up and down by the quick release mechanism).

    It was actually the housing for the rods and the screw. There was very little clearance around the screw and the edges were very abrupt and hard. Looking at the pictures from the post Craig linked to, it seemed like the older vise had more clearance around the screw. I took this picture today, I think it shows the tight clearance on mine.

    Screw Clearance

    Using a rounded file, I beveled the openings of the screw housing and then cleared enough inside it to allow for the tiny bit of slop the screw has. While working on it, I occasionally put it back together and tested it to see if I was making progress and it seemed like I was so I kept going.

    This is how it looked when I was done:

    Screw Hole Bevel

    And finally, back home on the bench with my vise jaws finally done.

    Back Home

    I’m pretty happy as this is my first bench and I finally finished it today.
