Hello Phillip,

Its a resin based rock hard, very heavy board that used in building.
It's used here in our Laboratories as work bench surfaces as its non-porous and easy to wipe off any spills.

I dunno where you can buy it from TBH. I'll ask the chippies, bare with me.

Here you go Phillip,

Our Joiners used to order it from here, they haven't done much work using it recently.

It takes 4 blokes to lift an 8'x5' 16mm sheet of it off the lorry!!! Really heavy, it very expensive though, be warned. 2 years ago they paid about £180 for a 16mm sheet. Gulp.

See if you can find anywhere local where a research lab is having a clear-out

Thats what made me think of Trespa when I read that lots of you chaps were exprerimenting with high Mass plinths. It might be **** in this application but I'm keeping my eye's open for any off cuts to experiment with.

Since wood had different mechanical properties along different directions changing the orientation should help.

Has anyone tried polyurethane glue for this? It sticks like s**t to a blanket, expands to fill gaps, and if applied thick, sets to quite a soft frothy consistency which should be very lossy. If you don't put it on thick, but use it as recommended, it's also very strong.

You can get it here: http://www.axminster.co.uk/product-T...Glue-22585.htm

I was also wondering about Silicon Rubber Glue. Any thoughts?

Best wishes,

I wood think that is a very good idea. The only question being can it be spread thin and equally enough. It has a long drying time so the plinth might have to be clamped for a longish time.

Yeah, polyurethane glue is ideal :-)

Thanks Gerry.

Hi James,

Good, get that, but what do you think of my silicon glue suggestion?

Best wishes,

Greg

I haven't used silicon rubber glue but it looks good. Certainly worth trying.
