attaching pyroceram to platen

meteogeek · Mar 13, 2003

I attached my pyroceram piece to a steel platen using Devcon epoxy. But as soon as I bolted the assembly to my existing steel Griz platen the pyroceram assembly flexed and the ends of the pyroceram detached from the steel. I roughed the steel with 100 grit sandpaper, but of course the pyroceram is slick. Any tips on attaching the pyroceram to the platen? The only other thought I had was to bolt my steel platen to the Griz platen and then epoxy the pyroceram to platen assembly.

Thanks in advance,

i would recommend getting a metal platen that is closer to the length of the pyroceram one you have and epoxy the ceram to that. much less flex, epoxy should hold fine.

All I use is vinyl double sided tape, I got at wal mart. I have been useing the same piece of glass attached to my platen this way for about a year and it hasn't moved a bit.I wouldn't hesitate to use it again when I replace the glass.
I don't know if your glass is longer then your platen, but mine are both the same length and width.

Good luck

I used this silicon sealer....works like a charme

I have two platens for my Grizzly(thanks Chang and Grizzly), and one is slightly rounded, so the ends of the pyro ceram wouldn't contact it. I attached it to the flatter one instead. used contact cement myself. It shouldn't be too much work though to rig up a flat piece of steel that can bolt in place of your regular platen and have the pyroceram attached to that.

sorry to intrude on your thread, but speaking of mounting, how do you get the graphite mess off the stock grizzly platen? or do you guys just glue your new platen right onto it?

I'm with Bill and have mine mounted the same way.

mmm,
I was just able to pull the graphite tape off mine.
If you have to scrape it off, try soaking it with WD-40
first. It always makes taking gummed backings off easier for me.
IMO, unless you have a very flat original platen, it isn't worth the effort. You can build a better platen for the Grizzly quite easily and cheaply.
I made mine with a piece of hardwood,some precision flat stock, lag bolts/hardware and two sided tape.

Here is a pic of the front. The flat stock is mounted to the wood with the two sided tape(it's not going anywhere).

A back and side view, showing the lag bolts and mount.

I just mount the glass over the flat stock.

I put my pyroceram on with JB Weld and it's been on there for some time with no problem. I tried the graphite and didn't like it. It wears to easy.

I also used JB weld and it has worked well. I also have not had a problem with the static electricity shock that some users of the pyroceram platen have experienced. I have wondered if the JB weld helped to ground the pyroceram to the grinder which is also grounded. I live in the dry southwest where the conditions for static electricity are excellent, yet don't have a problem with it. Tom Lewis

I was wondering the same thing, as I have yet to see the shock yet either. i dunno, haven't used it a huge amount yet though

Thanks all for the enlightening tips. Yes, the steel that I attached
my platen to is 9 inches long as opposed to the pyroceram which is
6 inches. I will cut to the size of the p'ceram and probably try the
two-sided tape.

Thanks again,
