Glass linner for the platen

I was hopping to get some input on ceramic glass liners for one's platen. I'm thinking of adding to reduce heat build up.
 
Do it.
It can't hurt and it'll help keep flat stuff flat. Last year I started using ceramic tile (12 x 12) that I cut on my tile saw. I'm still on my first piece out 4. The whole tile was less than 4 bucks.

The pyro ceran or fireplace glass works very well. I have been using some since 1999. I found many glass shops will sell it very cheap if you buy more than just the one piece and have been given pieces when I had windshield replacement done. I just get it rough cut and clean it up on my belt grinder with a cork belt. If you get them to finish it tell them how to round out the edges or they may destroy them by doing too much. I'm thinking of trying a tile as Rudy has been doing. I now have a small tile cutting saw.Frank
 
Thanks' guys , gives me some solid idea's , looks like a trip to the tile shop is in order. I think the tile will be less likely to splinter if there's a problem.
 
The Ceramic glass works great, the tile works great and is very inexpensive if you have a tile saw. I've been using the double sided tape to put ether one on. With the glass the double sided tape will allow you to use both sides.
 
JB Weld is the only thing I would use to hold on the ceramic glass. Everything else I have heard used has failed with predictably bad results. We run 4 grinders with ceramic and have for years and only use JB Weld. It will take the higher temperatures better than most epoxies.
 
Should of clarified that Boss,I do use JB weld as the adhesive.I think I got that tip from you when I was looking for platen materials.
 
Went to Lowe's today and picked up some ceramic tile and to let you know that they were very glad to cut the tile to size , no charge. They were very interested in what we do.
 
I think I'm going to try that. I have noticed a distinctive shallow spot on my platen where I profile my blades. I have also noticed the platen gets warm after grinding a while.
 
IMG_3731.jpgIMG_3729.jpg Here are a few pix's of the platen , I will clean up the sides in the morning . Please note I added 2 8-32 allen head cap screws for safety in case the J B Weld lets go.
 
Mine's black smooth tile....it'll go faster.
:9:

Make sure you radius the bottom and top edges. If you don't the top edge will grab the taped joint on a belt and peel it back. The bottom will do it slower but still peel it.

Thanks' Rudy , radiuses on each end just hard to see , Sunday we take dinner to the in-laws but Monday I will be grinding and smiling.
 
I use JB weld to attach my glass as well but yes I use bumper lips top and bottom in case of a release!

Here is a tip.

I bumped my ceramic glass on my platen with the rest one day while readjusting it. I bumped the side edge of the glass. It took a chip out of the underside of the glass, a quite large chip but it didn't come through to the face of the glass. I mixed up some JB weld and over filled the hole/chip and once set up ground off the excess and she is as good as the day it was set in the JB weld! I have been using it like that for a couple of years now!
 
Wow guys, why didn't I think of this??? I've noticed all of the imperfections in my platen and also noticed what it can do to the grind lines and finishes on numerous occasions. This is a great idea! Funny, I've been cutting tile and glass for years as my regular job and never thought of it!! I guess sometime you can't see the forest for the trees in it, right!
 
1/2" Granite and JB Weld works very well.

I don't think there are many things that are more stable, ubiquitous and wear resistant than granite. Keep it simple.

Reground a kitchen Knife that I had a hard time getting flat , the ceramic platen seamed to make a strong difference . It also moved my line of sight out from the plane of the idler wheel and that helps with blade contact.
