Adhesives for holding "Glass" to platen


Well-Known Member
While I'm a newbie to knife work, I've been a benchrest rifle competitor and reloader for 20+ years. I often -- but not always -- use JB Weld to bed actions to stocks and for various other purposes and I pretty well swear by the stuff. I'm sure glad everyone hung with this discussion until some kind of resolution was reached. It reminds me of advice I've received here that when gluing scales on, you don't want to compress too much, because you'll squeeze out too much epoxy. That's pretty similar to what Ed ran into, except with a glass platen, right? I also picked up good tips about warming epoxy in order to get it scraped off. Good thread.

Used contact cement on mine (with a shelf). The old school stuff that’ll get you high if you’re not careful! It’s been on there 4 or 5 years. But I probly only make 4 or 5 knives a year.

I use JBweld and have for some time. I did research to find the highest rated temperature epoxy and JBweld was the highest I could find. I would recommend a little shelf for your glass. I can be as simple as two screws drilled and tapped into the metal platen.

Where did you buy it? Is it tempered glass?

Don't use tempered glass. I know this from experience. It is not the same stuff and will easily crack from the heat. Boric silicate (or variation of that) is what you want. It is designed to handle the stress from heat.

I second Tracy's input..... some other "handles" you'll hear it called is "Fireplace Glass" or "Pyroceram"....... I have a local glass outfit that calls it "Fireplace glass"...... I get mine there simple because it's usually not offered in the sizes I need/use, and if I buy it there, they cut it to size for free. Even with that, it's usually between $24-$32 per piece, but unless I do something dumb, like drop the platen on the shop floor and break it, the "glass" lasts a LONG (and in years) time for me.

However, if you have platens that are "standard" sizes, it's best to purchase from folks like Tracy/USA Knifemaker you know you're getting the correct stuff.
