Incidentally, what do people do in regards to sash-cramps marking stuff? Do you cover them with anything, or do you just make sure they are not touching?

Wax paper between the clamp and the wood stops them getting covered in glue. I'm sure it would also stop the iron reacting with the wood and discolouring it.
 
I usually use cling-film, when I remember :) I was thinking about painting them or something though, but not sure what type of paint to use that would withstand the parts sliding over it all the time. Maybe hammerite I suppose, I'll have to check how much clearance there is n'all.
 
Masking tape normally. I do forget often though. I thought about spraying my t bars back to blue but the abuse they get and the constant moving I thought whats the point. Still I have a old record 52 1/2 quick release vice that I plan to bring back to the blue colour.

Thinking about it I have some 4D clamps thats made from some oak. Its a bug'ger when I forget to put tape on them before (hammer)
 
I'm rather puzzled with the clamp threads I've read here quite a bit. It seems that no-one ever mentions pipe-clamps when discussing options. I mean that in either positive or negative terms. I'm looking to stock up on clamps soon and the 'Pony' pipe-clamps seem to be rather good in terms of price, quality and versatility. Please correct me if I'm wrong.

And what about hand screw clamps? I always imagined these to be a nice addition in a workshop to hold irregular pieces to a bench etc. Again, I'd love to hear peoples thoughts.

I bought some Pony Clamps a few years back but never got around to buying the pipes. But last year when having a new boiler fitted I remembered them and my Plumber got me some and kindly threaded them too. They are very versatile and can easily extended with the supplied screw fittings. Very popular in the States but not so over here?

Rod,

do you think its the fact that the pipe clamps need to be threaded is the reason that they are not popular or the need to get the pipe separate. I think the pipe being used might be much more common in the states than here in Europe.

The Pony Clamps fit onto standard 3/4" bore black iron pipe with 3/4" BSP thread.
I'm sure the pipes are pretty common from Plumbing supplies and I think the thread is standard too?
Axminster sell the clamps and pipe kits.

I think they come in 10' standard lengths - my plumber cut them in half and threaded them for me so with the supplied couplings you can achieve massive lengths if ever needed?
In the American mags. you often see lots of them stacked up in their workshops.

All record sash cramps that I use, would second hand not be an option. I see from time to time second hand examples on market stalls if they are not too bent or you could refurb with wire brush etc.

I like the look of Bessey and for the last 8 years I have been using also quick clamps but I always seem to rely on the good old Record Sash cramps for shear clamping power, quick cramps do not get the shear pressure on do they. The Sash cramps bolt together easily to give extension to length and I do have a selection of both heavier made jaw/thread and the lighter model. I did use two clamps that were over 12 foot I used them on large door manufacture in my apprenticeship, I was working for an old family joinery firm they had all the wooden shaped planes in a cabinet/foot operated mitre guilotine and those clamps. All that gear was far older than me and was working fine and probally still working today who ever bought out the company. I was made use them wooden planes to do some moulds because I cut some machined beading short, my journeyman said it was a lesson, it was, I was there ages running it by hand. I never cut beads short again.

Only issue with sash is marking and glue deposits, some of the PVA I use eats metal if left alone. Had a lot of bother once with a finger jointer machine particular prone to rust/pitting so you had to barrier cream the metal bits of SET/Carousel/clamp and clean down after use.

I used to make ply covers for the jaws so you did away with blocks. Least they were always in position, the paper/shrink wrap I always seem to forget to have it handy and end up with blocks or the good old ply plates.
