Was wondering if I can find it in the States:
the clamp is a slit ring of may be 4" OD, made out of
1/8 or so, spring-tempered steel. Works wonders when clampling
Is used extensively in Russia - this is where I saw it.
Doing extensive searches in US catalogs didn't show anything
even remotely similar ...
Trying to avoid having to make my own (1/8 drill bent with a home made
The ring has to be as close to ideal circle and be planar to work
Not at all like this one, no.
Just image 4" diameter perfect circle/ring, made out of piece of 4mm
(1/8) or so wire, slit so that ends can be moved apart and the steel,

Not what you are asking for, but I have made similar clamps from a
piece of PVC pipe, 4" ID, cut into appo. 1" "slices" then cut once
radially so they can be spread open into a "C" shape. I made about 20

small in D.
To try again :) - imagine 2 x 3.14 x 2 = ~12" long drill rod, 1/8 in D.
Now roll it into a perfect circle , heat treat and bingo - you got just
the thing I
am looking for.
Or, if you want to skip the heat treating part, imagine rolling 12"
length of music
wire of .100-.125 in D.
How about these...
