Hey Guys,
Let me just preface my question with the details of what i'm trying to achieve. I'm thinking of a lamp design that calls for a heavy base, the lamp shade is not centered and as such the base needs to be heavy enough to prevent tipping. The base would probably be in the ballpark of 400x400x15
So my thoughts were to laminate some thin wood (5mm) with some 5mm steel plate using west system epoxy. So the end product would look rather like 3ply plywood with the top and bottom piece being wood, probably some nice doug fir, and the middle section being steel.
My question is what do you think will happen in terms of expansion in warmer weather? The lamp will be indoors so the temperature would range between 10-30 celsius. I've done a quick search and found that steel has a coefficient of expansion that is two times :oo: greater than wood. I guess the real questions are, will i get away with this using relatively thin wood at 5mm? Will the epoxy provide some give and thereby eliminate cracking?
Has anyone attempted this sort of thing before and what did you find?
I suspect i already know the answers but if you have any ideas or experiences please share.
Cheers
