Does anyone have experience with ABS sheet I know it can be formed using heat, can it just be slumped over a mould or does it need to to pressed

It will sort of slump, but won't form detail without something forcing it. Also, lots of these plastics will try to shrink back to a less stressed form when heated, so you may have a problem with it wrinkling and changing size. Remember those chip packets you used to put in the oven to get minitures? Same sort of thing applies.

What is it you are trying to achieve?
Some pics might be useful.

I need to make a rifle case I can not find a commercial one that will fit, I can easily make one from timber, however I thought ABS would be much less weight, making a timber form would not be a problem, although heating a sheet large enough to use a die type form would be, If it could be just slumped over a form it would be doable .
Seems like timber may be the best way to go.

No - not rifles, but chainsaw bars
When all 5 slots are occupied its bloody heavy.

No I was going to just make a conventional type, however on thinking about it, I like that design, it has several advantages over the normal rifle case configuration, some food for thought.

Along with "bomb" like looking gas forge (which I have sold), SWMBO reckons the department of homeland security would take a keen interest in me walking around in public with such a box.

Yes I could go the vacuum rout, except I don't have a vacuum pump, and heating the sheet would be problematic, I don't really want to spend a few hundred on a set up that I will use once.

Lay it up in carbon fibre or fibreglass
A box like that is petty simple to make the reverse form for

Thanks for all the input, time to go back to the drawing board and decide which way to go, I will try and take some pics of the process, when I decide what the process is.
