did not see this one coming/now I know...
 
1 Attachment(s)
I have been using some odd 1/2 inch glass table tops to glue up
segmented rings thinking that the surface is smooth and flat, will
clean up easy, and not stick to the squeeze out. After gluing up
last night I went to true up the ends this morning and when I went to
take the half ring off the glass a big chunk stuck to the squeeze out
on my joint. Titebond 3 was the glue. Here is a pic. Anybody else have
squeeze out stick to glass enough to pull out a chunk of the glass?

Matt,

I am sorry but I did not even know that it was possible. Can you clean the chunk of glass that came out and use some version of crazy glue to put it back? If not it seems that you either have to replace the entire piece of glass or find a way to make that divot some kind of feature. However, I think you will need to pull out a few more divots to make it look good and then I do not know what that will do to the overall integrity of the glass. Good luck.

There is actually an art form called glue chipped glass that uses hide glue to pop off pieces of glass. It relies on the shrinkage of hide glue as it dries.

Thanks for the reply. I didn't know about the hide glue technique.
I guess my paradigm has shifted concerning the physical properties
of glass. I am attracted to the flatness of it when gluing up the rings.
Maybe some paste wax before glue up...

I will probably use the other side for now and not let the ring sit for
too long. Thanks.

Thanks for that Peter. Very interesting.

Waxing should work well to prevent chipping but the work will skate around so easily that it might be better to cover the glass with paper. An absorbent paper (not waxed or plastic coated) will remove some of the surplus glue from the wood.

Wow! Didn't know that could happen!
There's you having an excellent bond with tightbond3 on glass, and just a couple of days ago I had a major tightbond3 failure! Want to swap glue bottles??..:rofl:

If the chip is not too big in the glass, I wonder if a windshield repair place could fill it with resin?

Alex,

What a great idea. Like with your car, do you think they would come to Matt's house and work on it out in the driveway?:Laughing2: :Laughing2: :Laughing2:
