Paul Sellers Cam Clamp Roll Pin Source

[Michelle_K]

Hi all having watched the recent Paul Sellers can clamp video I really want to try and make a few as they are way to expensive. I am very new to wood working and will be using hand tools. I know I can get the bar for the clamps from b and q but I am having trouble finding the roll pins. In the video he said he got them from eBay but all I can find on eBay are the slotted roll pins but in the video he uses 4mm roll pins with out a slot. I just wondered if anyone knows where I may source them. Thank you.

I found lots of stainless ones that look like they would work.

If you have a means to easily cut material like this (e.g. a slitting disk/cutoff wheel chucked up in a power drill) you could use masonry nails as an alternative.

If you have a place near you that sell "Fastenings" nuts bolts screws etc would be a good place to start for rollpins,
or a garage mototfactors, selling garage consumables.

If you can't find proper roll pins the masonry nail option is still a very good one. I've used it myself.

Just remember that if you are using oak as your wood, steer clear of anything ferrous, as the metal will stain the wood and the wood will rust the metal.

Or something similar? Stainless would stop any corrosion problem.

I haven't seen the video, but Spirol coiled spring pins are far superior to the spring tension slotted type more commonly encountered, but I doubt whether it makes a lot of difference in this application where the wood is more likely to be the weak point than the roll pin.
A random internet search for "spirol" came up with
ebay supplier: http://www.ebay.co.uk/itm/5-x-20mm-A2-C ... SwBLlVeJvu
and a more conventional supplier: http://www.keysandpins.com/products/coiled-pins

I have made some and used the stainless ones linked to above, works great.

IIRC Robert Wearing's Aids and Devices book gave plans for these.

Edit; yes, page 32 "Guitar Makers Cramp".

He uses Aluminium bar, to make the cramp as light as possible.

Michelle, I was going to mention in case you didn't know that you could make clamps of this type by building up instead of by cutting mortises. Since you're planning on building a few you might prefer it to ease production.

This is mentioned in passing in Wearing's book that BB references above, but by the time he'd written The Resourceful Woodworker a few years later this had become his default recommendation on how to make these. There are numerous advantages to the build-up method but perhaps chiefly you don't have to worry about sourcing a chisel that matches the thickness of the metal bar.

You can also make this style of clamp entirely from wood if you'd like, and they often/usually have no metal pins so its saves you doing any metalwork if that would suit. There's one plan for this type in this PDF.

This is mentioned in passing in Wearing's book that BB references above, but by the time he'd written The Resourceful Woodworker a few years later

From the British Library catalogue;

The resourceful woodworker : tools, techniques and tricks of the trade. Robert Wearing, Batsford, 1991.

Woodwork : aids and devices / Robert Wearing ; Robert Wearing London : Evans, 1981.

I hasn't appreciated the date gap; I'd always (unconsiously) assumed that because Aids & Devices is
such a compact "index" of designs, it was the later, summarised and distilled, publication.

Thanks for pointing that out.

I was going to question the use of metal of any kind for what are basically luthier clamps, but I see ED65 got it covered.

For light clamping, going to the trouble of a metal bar & pins isn't necessary.

Our very own Steve Maskery put a "making of" video on YouTube!!
