I have no experience with that vise, but my first instinct looking at the pic and pdf would be to tighten those set screws. I'm assuming you've already tried that, but what happens if you loosen them? Does the play between the two components get worse? When you tighten the set screws do they seem to get tight, i.e. you can't turn them any further?

I wonder if due to wear the set screw is bottomed out in it's threaded bore before being able to make solid contact to the part it's supposed to be restraining. If so, maybe a new set screw that isn't worn might help. Just kind of thinking out loud here. Good luck.

call them, phone # on the website

 

Hey Andy, I tried that. Unfortunately no luck.

Greenriver, I tried them yesterday twice and again before sending this message, all I could do was leave a message and have heard nothing back yet.

 

take it apart at the set screws and inspect/clean it

try unscrewing the barrel from the post

 

Very true Norm. I did what you recommended after I applied a little more pressure than I tried initially. I think I'm just going to locktite the one into the other since it just threads in. I can see no reason you would ever want it loose. Thanks all.

I'm still baffled by the top set screw which tightens onto the internal component that is supposed to turn for rotary use. I don't understand that since there is a knob for that on the backside.

 

I use the same vise. The screw by the rotary handle is designed to be the "rotary lock." The top screw is intended to be a tension adjustment for when you have the rotary unlocked. You CAN achieve the locking effect with either screw, but that's the design.

I have no idea what is causing your vise to be loose at that junction (sorry). Only thing my non-handy mind can come up with is that one of your set screws might be stripped?

I mostly love my Barracuda Jr., but the regular jaws don't hold hooks smaller than about a 12 worth a damn, and the midge jaw seems to back off ever so slightly when the cam lock engages, rendering it useless. Great for larger hooks (most of what I tie), but.... I actually bought a Regal non-rotary head for tying small stuff. Conveniently, it fits perfectly in the Barracuda Jr. pedestal....

 

Just wanted to provide an update and hopefully some information for other users. I heard back from Dyna-King and the representative was very helpful. I totally understand it taking a couple days to get back to me companies are busy. Here is what I learned:

The two pieces are threaded together and it is necessary for them to be tightened to eachother. This is what I had done on my own using an allen wrench in the head of the set screw to generate additional torque (although be careful not to strip or break the screw). I asked about loctite and she said I could use some, but to be sparing and to keep it away from the Delrin sleeve that allows the rotary action (just a dab on the threads). The top set screw is to provide additional tension on the rotary action of the vise and proper adjustment is to tighten until you feel it make contact with the Delrin and then back it off 1/2 of a turn.

Hope this helps and thanks to everyone here and to Dyna-King. Apparently the vise which I only recently acquired, is close to 30 years old so WOW!

Well…this news makes me feel old…!!

A protip about locktite; do NOT use the red locktite in this particular application, unless you intend to NEVER move those screws again. Don't ask how I personally know this to be a fact. Sparingly use blue. Getting screws to loosen that have red locktite generally involves heating the piece to 500 F.

 

Loctite 222 (purple) - is for small screws. We use it almost daily on # 6 set screws. It keeps them from vibrating loose but they can be removed later. I first learned of Loctite 222 from bicycle wheel builders who used it on spoke nipples. It kept them from loosening during use but still allowed adjustment later.

And yes, traditional Loctites meant for metal fasteners will destroy some plastics, specifically Polycarbonates.
