============= I can't quite picture what you're doing but band clamps might help. They're long pieces of fabric which wrap around the workpiece and can be tensioned. They will hold irregular shapes so might do your job. A bit like the old-fashioned 'spanish windlass' principle. They're available from places like 'Focus' etc.

Have a look at Bessey clamps -

Their TGNT series come in a size range covering what you are asking for.

I don't have any of this particular series, but do have a variety of other Bessey clamps and they are very good, so I would be surprised if there was any problem with these.

I saw some at the Axminster tool show last week (I think). Axminster themselves only seem to have the 400x300 model (at £64) but would probably order the smaller one for you. In Germany, the smaller

can you use wood strips to press the joins together with the clamps you have at the edges?

Do you have a bandsaw ? If so, make your own wooden cam clamps. Beech is traditional, but even plywood works. You can make these with as long a jaw as you like, you can put lumps and bumps in to clear obstructions, and they're lightweight so you can use plenty without pulling it off the bench.

How about this?

Make a frame from two long bits and two short bits of 4x2 and a few coach bolts (or use 12mm ply and screws on both sides for the end pieces). Cut a load of small wedges and drive them between the beams to apply pressure. You could probably apply the glue then pin everything to the bottom beam to hold it in place while you drive the wedges. Use paper or plastic sheet to stop the shell from sticking to the jig.

Here ends todays "good idea" :-)

Many thanks for your contributions. I think I'll go with a combination of the clamps I have and the ideas from mrcheerful and Rob (excellent artwork), using wedges in the centre area.

So refreshing to dive into a newsgroup and get prompt sensible answers that do actually answer the question with no abuse.

Thanks and best wishes to all of you.
