Lexan platen liner

[dbalfa]

Has anyone here used one of the Lexan/Corel/ceramic platen liners? If so, what did you do to attach it to the platen? How long did it last?

Hey Bubba,

In another life, I used the platen liners that were supposedly made from the same thing mama cooks caseroles in, and epoxied them to the platen.

I also took the extra step to "tack" weld a little 1/4" piece of cold-roll to the platen (under the liner) to support it. (You know how epoxy can become "snotty" if over-heated"). This was just an extra precaution in case the liner decided to "slip" down a bit.

Of course, that was on a "Grizz" that was running twice-the-speed-of-light .

Lexan is a plastic. Where did you see any platen liner made of Lexan? That's a new one on me. The only platen liner I have seen mentioned in about 1000 threads on the subject is always pyroceram (or similar high impact high temp glass) or sometimes a piece of hardened tool steel.

With glass, about the safest way I know to mount it is to attach a small piece of metal across the bottom of your platen so that the glass has a foot to rest on. After that, I use double sided carpet tape to hold the glass but some others prefer epoxy. Under no circumstances should you use a glass platen without the metal foot. If the tape or epoxy lets go - and I don't care how perfect your epoxy is - that glass will go into your wheels and shatter, it will become a glass grenade! I was lucky enough to survive that unscathed and there is at least one other maker with a similar story so words to the wise...

I'm not sure I would even think about try lexan for a platen face. I can't image it would hold up for more than a few minutes to the heat/friction. Even glass platen faces can get too hot to touch, and after a while they will even become somewhat grooved from the belt traveling over them.....so I can't image lexan holding up much at all.

"Lexan" was simply my "reaching" for the term....I should have said Pyrex. I think that is actually what it is made of, or something like that.....

Thanks fellas, I will get the welder out!

I just put a glass platen on my Grizz. Since I don't have a welder I came up with a different solution for my foot. I just tapped two holes under where the base of the palten would rest and threaded a couple of bolts in from the back - double nutted and thread locked of course. The platen is attached w/ high temp JB Weld and rests on the bolts. So far, so good!

My pyrex platten is attached with double sided automotive tape, it's been going strong for 2 years so far. Also have a "stop" welded at the bottom of the glass.
