Title: Schweikert Handscrew Clamps
Post by: lvgforum on February 22, 2015, 04:45:19 PM
Betcha these haven't been seen here, at least I haven't on Google or this site search.

Anyone know anything about them?

Never seen them. Are they metal?

Machinists parallel clamps. I have a pair just like them. I have never had a use for them. Do all my clamping with C- clamps.

I have several of these and all are around the same size (screw length of about 2 1/2"), and I agree with EVILs description. None of mine have a name on them and I suspect due to the quality they may have been a High School or Trade School learning project. Yours appear to be good quality. I tried Google and a few other sites but found nothing on that name.

If it was E Schweikert, E for Elliot I'd would have said I knew him!
He would have been so perfect on the name stamp!  R.I.P. buddy!

Imperfect knurl and milling cutter marks indicate a shop-made "G-Job".
Good project for the shop.
Seem to have fallen out of favor in recent years due to Kant-Twist and the convenience of C-clamps.

I just went and checked mine.They are made by the L.S. STARRETT Co. #161-C. I have owned them for over 30 years and this is probably second or third time i have looked at them. Can't get much better than Starrett. Quality machine work on them. They seem to pretty to use.

The little sheet metal keeper is on all the Starrett's I have seen. I don't know if it was patented or not.

I have some Starrett clamps like those. They came with some others that are kind of like little machinists clamps, 3/4" wide jaws with a 1" capacity.  The factory made type command a pretty penny, I have noticed.

I think they are good for small metal work and I imagine they work well for modeling or miniature making.

In the UK they are known as toolmakers' clamps - Moore & Wright of Sheffield made them, but every apprentice made their own as one of their first pieces - I made my first set at 14 or 15 when doing metalwork at school - as did most of my pupils when I taught metalwork (1974 to 1982).....

I found another one the other day. Larger and no name. Probably a students project. Not as nice as the Starretts.

Shop bought ones usually have hardened faces on the jaws, home-made ones seldom do - being made from mild steel, unless case hardened....

I have four of those lamps hanging by the bench , never found a good reason to use them, but I don't do machining . I keep them around , just in case.

I'm starting to wonder if this Schweikert wasn't just a home project. I found a little machinist vise with the same name. Here is a picture.

I use those clamps, I find them useful holding small parts together when I am doing silver work. I use them in different little quick jigs at my jewelers bench.

I doubt I would have much use on my woodworking or welding benches.

It has as much to do with scale as anything,  I suppose.

Ah, I have a couple of those without the name! I never knew what they were for (other than the obvious...holding things).
