Cracked glass piece

[ed22]

Hi there,

Restoring an old set from a garage sale and was just wondering if there is a process to repair cracked glass?

Any input would be great.

You can glue it back together, but you'll always see the joint, so it's best to replace the part. Which kit is the piece(s) from?

Or you could use clear Evergreen sheet to make a new piece.

Exactly what glass piece are you describing?

[Harry P.]

You can glue it together and polish it, but you'll never be able to make the crack invisible. Best bet is to make a new piece. If it's flat, it's very easy to cut a new piece from clear acetate sheet using the old piece as a template. You can also use the acetate if the glass has a curve to it, but it won't work for compound curves.

If you're talking about curved window glass, you can use the Squadron Thermaform method, which was originally developed for duplicating aircraft model canopies. First, make sure your cracked glass is glued, filled and sanded to a smooth finish, and even primed and sanded. Or find someone who will lend you the part you need to use as a buck.

You don't need Squadron's materials; just thin clear sheet and a good heat gun. Be sure the part you're copying has very solid backing at all points so the downward pressure doesn't crack it again.

PS: This can be a somewhat tricky procedure, so practice on expendable or durable items, such as a spoon, to get used to it.

PPS: Latest news from aircraft modelers indicates that Squadron has put direct Thermaform sales on hold due to low demand. You might be able to find it somewhere, though. But I've used alternate materials, such as a clear report binder cover, with success.
