    Default T(?) studs, where do I find these

    Hey y'all,

    I bought a gently used Taiwanese 5" compound angle vise the other day. It's cleaning up well, except that the studs on the circular base were totally stripped out.

    These are probably a retrofit, as I believe they're the only imperial hardware on the vise. Looks like 1/2"-13, 1.5" tall with a turned base. 1" at the widest, 3/4" at the narrowest.

    Are these a standard item I could buy off the shelf someplace?

    Is the internet a shelf?

    googled t slot bolt and got lots of similar items, but you need to determine if the size is right

    or if you have a lathe its a quick job

    A 1/2" x 13 standard bolt is 3/4" across the head flats. You could probably just mill those to the thickness you need.

    But... that would probably allow the bolt to turn in the channel unless its tight enough to hold on short flats.

    How about a square head bolt?

    I have used square heads and just hand snagged them on a bench grinder till they fit.

    I think you have to thin the >11/32 to 1/4. (?)

    Be careful, bench grinders bite.

    Here's a previous discussion that shows the ones used in a Kurt vise.

    T-nuts for Kurt swivel base

    Or you could make your own?

    Made these to increase the clamp load of the fixture I was mounting to a Kurt swivel base.

    Thanks everyone for your suggestions. I guess I'll need to measure the slots and see how wide the stud needs to be at base so as not to rotate in the slot. Maybe I can mill down regular 1/2"-13 T-slot bolts or square head bolts to a suitable size.

    I was surprised to see these stripped out like this, I can't imagine locking the circular base warrants that level of gorilla-torqueing the nuts?

    On a tangent, the vise has a tag saying "GS Taiwan" and it's a 3 way compound with 5 inch jaws (or maybe 125mm). I've done some searching to try and find any kind of information on the manufacturer, parts list or some, but so far I've come up empty.
    Anyone know who would have made those or where I might find a parts list (for my curiosity)?

    there was a vise coming out of China about 10 years ago that a two-hand tightening could break the front jaw right off, and so it might land on someone's foot.

    I turned some replacements this afternoon, just went by the same dimensions as the horked hardware. I guess we'll see how much gronk it needs to hold tight in use.
    I still don't think this is original as e.g. the screws holding the jaws in place are M8.

    Safety feature. That was the No-Crush vise for fragile work.

    Well I sure hope you used metric threads on the ones you made, it would be tragic if it was not all metric!

    I just made it 1/2"-13 like what came off it, but I fear the old Deckel may reject it - or at least make fun of it.
