Topic tags/keywords: laminating glass wood led lighting question

I have a desire to make a table that uses 1 1/2” lumber laminated with 1/2” glass cut in 1 1/2” strips such that the glass panel in parallel to the lumber and the 1/2” width of the glass is seen from the top of the table. I have the tools to drill the glass so that the glass can be bolted between 2 boards and the glue to bond the glass and wood together. What I am wondering if wood expansion and contraction will crack the glass or if the bonding will sufficiently reinforce them safely together. I want to do this so that I can underlight the glass using led lighting. Thoughts?

Exciting ideas there. I’d say go for it. If you don’t bolt it together, the wood can do its moving thing as needed.

Either it will work, which is good,

Or it won’t and you’ll get knowledge out of the deal, which is good.

On my wall it says, “Try, Fail, Learn.”

Kindly,

the glass will dull a cutting edge real quick, if you don’t mind sharpening your knives often I think it will look cool too.

Sounds like it’d be an interesting look. If the glass edge is clear, I’d would wonder what the glue would look like—it might be a cool effect, or it might look really bad. If you’re thinking of through-bolting it all together anyway, you might just skip on the glue entirely and let the wood show through.

As for expansion, having the grain oriented as if quartersawn ought to keep most of the expansion in the vertical plane instead of adding pressure to the glass.

Make some sample “sandwiches” and observe what happens
as the wood moves.

You may consider using rubber shock washers countersunk
into the wood or something like that.

I like Loren’s idea, try a sample sandwich and see how it works before investing time and effort for a potential epic fail. The idea sounds cool. Make a sample and post a picture….

Thanks all for the comments and ideas. I think the best direction is to mock up a few prototypes – glued and bolted, bolted only, glued only and see what happens. I am looking at using WeldBond or E6000 to maintain as transparent bonding as possible.

Have your say...
