Attaching Pyroceram?

I just received my long-awaited, and eagerly anticipated, 2"x12" piece of pyroceram from the Darren Ellis:thumbup:.

I can now improve my platen. One problem though...........................

My platen is 2"x10" and I need to shorten this larger piece.

How do I do that?

Now I just need to affix it to my platen. JB WELD gets a lot of votes here. Are there any other adhesives I should consider? Anything exotic? I DON'T want this sucker to self destruct on me if it gets hot:barf:.

Thanks in advance..................

A glass cutter will shorten the piece. Score your line where you want to cut it, then put a ruler or some such under the piece. Keep the scored edge close but overhanging the wood. Then, while holding the long piece firmly, snap down in the short piece. It will pop right off. It's not unlike cutting drywall.

If you don't want to take that chance, a tile cutter will work.

JB weld works fine and is good to a higher temp than regular epoxy.

The biggest concern is not the glass getting hot, it's the adhesive! If it gets too hot, it can weaken and the glass slide down the platen.
Then you're in trouble!
It's the smart knifemaker who will weld a little "ledge" right underneath the pyroceram to keep it from sliding down.
You don't need anything exotic to hold it in place. All forces against this glass will be PUSHING it to the platen! Nothing is EVER trying to pull it off. You are pushing on it, the belt is pushing on it.
I've used Heavy Duty Exterior double sided 3M mounting tape on three different machines/platens for about 4 years. Never had the first one try to come off.
 
Okay then.....

This all sounds doable

except WELDING the ledge on my platen. Grrrrrrrrrrrrrrrrr. I am takin' a welding class this fall but for now I think I gotta drill it, tap it and screw a ledge to it or take it somewhere to get it welded. H'mmmmmmmmmmmmmm. I will figure this out today.

One question though. How thick should the ledge be? I assume the same thickness as the pyroceram. Better to ask now then be sorry later I spose..............

Thanks for all the ideas. Sounds like snapping it off should be doable and JB Weld, which I have on hand, and handles heat well, is the ticket. Maybe I'll take a pic or two of this.

JBWeld should hold you just fine. Unless you're heating the entire platen to 200+ degrees, you're not likely to have it slide on you. I know at least one maker who has broken the pyroceram with heat multiple times...the JBWeld never let loose.

Based on the colors of some of the knives I've ground (ruined is more like it) I'm sure that things get hot around that platen. But I'm also sure that the platen has enough mass to dissipate heat well.

So JB Weld it will be.
