I try something that work for me and don't know if it's been done before, and wanted to let you know.
I ordered some replacement Ceramic platen liner material, I used 2-ton expoy to hold it on. And was wondreing how to remove it. I place the platen in a toster oven at 325 degrees for about 30 minutes, removed it and just touch the liner material with a small hammer and it fell right off, real easy to clean up.
 
I've have only used Devon to glue my handles, but I also use the screw rivets too. Never had any problems. What do you use?
 
I don't understand Stephan. Why don't you? What epoxy do you use, and what temp does it melt at?

Ricky, I'm curious whether if would have rehardened after heating. The Chem-E at my last job told me that epoxies would re-harden even after getting heated past their melting point once cooled. I've never tested this. But he was a pretty smart guy. I might have to give your test a try, then allow the parts to re-cool and see if it re-bonds.
 
I use 2 ton epoxy. I have had to remove handles that a guy wanted to change out and that taught me......its hard to remove a properly glued and pinned handle. I dont peen my non threaded pins either. How many guys peen mosaics??

directly prior to gluing up my handles I drill small angular holes on the inside of the slabs, rough the steel surface so no oxidation can be there, and I already have plenty of holes for the glue to pass between the tang.

I have never had a handle come off yet.........yet;):p:D


BUT I DID HAVE MY FIRST PLATEN COME OFF AND EXPLODE ON ME!!!!!
made me weld a small 1/8" rod to the bottom of my steel platen and I glued another ceramic platen on. Find out tomorrow if she blows or not :)

i just throw mine in a plastic bag smack it with a hammer,glass comes right off :) then i saok in acetone to remove any leftover epoxy.takes 3 minutes :thumbup:
 
I have used pops stuff as well and it worked just as the Devcon 2 ton for me. Maybe I have been lucky and havent had any issues with 2 ton of any type.

I havent used the slow cureing kind for fear of getting everything cleaned up and some still oosing out and making me angry later:D

I order from pops when I have abunch of belts I need :)

I order everything from pops and Tracy, love the service and would MUCH rather give my business and money to a supplier that I can pick up the phone and call for a reasonable useful answer, rather than a sales pitch

but tha'ts just me

I put my platen on with JB Weld and tapped a small hole into the bottom of the steel platen so that the bolt head just barely protrudes out to catch the bottom of the ceramic plate.
 
pops is the way to go. IF pops aint got it I go to Ann Sheffield. last place is a big box store. McMasterr Carr is decent for certain items.

Pops had me the first time he shipped my over $100 order without me even paying him for it first!!:D
 
I take it there's no way to get 'em off in one piece once you've put them on with JB Weld? Well, in my case it'd be 2 pieces. I'm considering changing mine since it's cracked. The crack is a bit less than 2 inches from the bottom of the platen and goes all the way across. I should probably just leave it alone since most of the time it doesn't seem to hurt anything. I put a P120 J-flex belt on backward the other day and ran it at low speed to smooth down the edge and make sure it won't try to grab at my belts' splices.
 
Mark, you might setting the platen on dry ice for a while then tapping with a hammer and/or working a chisel or screw driver along the edges. We did that to get embossing dies (Copper, magnesium or steel) that were epoxy or JB Welded to a backing plate (steel or aluminum) without messing up the metal components. Once the adhesive got good and cold it sheared easily.

I use a piece of hardened 1/4" O1 that is drilled and tapped to the platen. No explosions, no glue and fast to change out when it wears out. Cost's less then pyroceram to. The old one will be used as template for the replacement. Two years of heavy use and no wear at all.
 
Let get real people. How often is a finished knife subjected to 325°, for a 30 minute period of time, by any other means than on purpose? I would expect more damage than just to the epoxy bond. Most anything can be destroyed when pushed beyond It's practical, and reasonable limitations. Devcon 2 ton epoxy will hold up to any normal, reasonable expectation, very well.
 
Hay Fellows-i Have Not Been Introducted Yet But Have Made A Few Comments Last 2 Yrs--
I Am Useing A Peice Of 1/4 Cocobola With 2-ton And It Has Been Doing Good For 6 Mos

The only problem with Cocobolo is some people are allergic to it, and running a belt over it wiii produce dust!!
 
I use 3M 420 adhesive film to put my platten liner on. It never hardens, and if you pry at it you can get it to release. But it hasn't let the thing go for over a year now. It also never freezes and can stand a fair amount of heat. 420 adhesive is an investment up front. But I use it so much in the shop that its worth it.

Jigs, fixtures, temporary things. The little fixture I made to hang the baby gate on the wall has been there for over a year too. When I want it down I'll just pull it off and roll the glue up into a ball. It won't damage the drywall, and isn't greasy. You'll have to google it, and you'll have to really dig deep for a supplier though. This is an industrial product.

3M will send you a sample if you write to them.
 
I would be more concerned about what low end temp my glue quit at than high, I have never used a knife in temperatures over 300f and have never experience temps over 115f. I have used them below zero and have experienced -40 below. How many glues hold at -40?

Thanks Todd. But... won't the extreme cold also make the ceramic liner more prone to shattering? In the end I'll likely just wrap the platen in sack cloth and beat the snot out of it with a hammer, then grind off the JB Weld that remains.
