Any info on these C-clamps used by Adrian Sorolla

[OlivierF]

I saw these photos of Adrian Sorolla’s La Mahonesa build on a FaceBook post.
The clamps look hand made. Does anyone have more information or ideas on what he used for the “c” clamp body.


I was thinking maybe brass flat stock that’s been bent around a pipe or some other form. Then thought perhaps the brass would be too soft and not hold it’s shape when clamped… it’s a head scratcher…

They look nice, but any small commercially available G clamp would do the same job.

I would add that they can be made to do the same job, but even the smallest ones do not always fit into tight spaces on occasion. No reason not to take a clamp to the grinding wheel to take off material so it will fit in the tighter spaces. Where there is a will there is a way.

If the pressure needed on the wood is so much that the clamp may bend, would it be better to shape the piece(s) of wood so not as much clamp pressure is required? Just a thought.

Yup, I have a bunch of small ones. I was just curious as I like the style of these.

The handles are immediately recognizable as gluing dowels, the shafts are brass slot-head screws, and the Cs do appear to be bent bar stock, as you said. The problem is that the screw head is not free-floating and has a slot in it, so it’s going to mar whatever is getting clamped unless you leave it so loose that it wouldn’t be serving any purpose.

I bought these at dictum dot com. Great stuff.

Hallo zusammen,

Ich habe meine kleinen Schraubzwingen aus ALU-U Profil selbst hergestellt. Diese haben die Größe von 2x20x20 und eine Breite von 6mm. Die Größe der Zwingen reicht bis 3 x 50 x 50 mm.

Aluprofil auf Länge schneiden.

• In einem der Arme ein Loch für ein Gewinde bohren. (M3; M4 oder M5)
• Den Arm ohne Loch in einen Schraubstock spannen.
• Dann den Arm mit dem Gewinde etwas zur Seite biegen, damit man von unten eine Senkkopfschraube in das Gewinde drehen kann.
• Senkkopfschraube muss so lang sein, dass man am Ende eine Flügelmutter oder eine Sechskantmutter aufkleben kann
• Den Arm mit dem Gewinde und der Schraube wieder in die Endposition zurückbiegen. Fertig

1. Put a small piece of wood between the screw and the wood part being fixed.
Problem solved!

That’s true, but then things start getting fiddly.

1. This entire model ship building business is fiddly from beginning to end.
You do what solves the problem. End of discussion.
2. You have to be slightly mad to do any of it.

My father attempted to teach me good woodworking practices during my childhood. One of his rules: always put a wooden shim between a C clamp and your work surface.
