Carbide platen...?

I don't think so ..........Tungsten carbide is far away with hardness from Rex 121 ....Rockwell C 89+ .......on Mohs hardness scale is 8.5 to 9.5 (diamond being 10.0) ;)

WRONG! Your thinking of a Carbide end mill bit. Sure, it may be...but the plate I'm able to find is C-2 material. It is no where NEAR 89+:confused:

Do some more searching before calling someone out. K sport?

Well now you are wanting to make an improvement on one of the very few things I presented on the Knife Forums way back in 2000 or so. I too have wondered about a change on the glass to something that might be better, but in fact have always come back to the glass because of the ease of installation and cost.I haven't given much to the Blade Forums except a lot of interest and perhaps confusion but I am actually proud I wrote this up. I haven't tried the ceramic tile yet even though a friend cut some for me and says they work well. Many times I've had some glass replaced in a door or car window I've got the same co. to cut me a half dozen pieces or so. The prices have been very good when I did it this way.

I don't understand your post. What are you taking credit for? Because I'm sure pretty much everyone here came to this conclusion on their own. What is the "THIS" you wrote up? Because you didn't write up THIS thread. Sorry, your post is just confusing, and seems a little out in left field.
 
The other thing, DUH! Tungsten carbide is measured on the Rockwell HRA scale w/ 60kg load. Not the HRC scale w/ 150kg load that most of us are familiar with. Look at the conversion of the A to C scale and get back to us.
 
As for static electricity, I took a beeded chain, like a dog tag chain, and connected one end to my grinder and I think the other end into my beltline. If it gets caught in the grinder some how, it just pulls out from your pants. It works great on micron belts.
 
There's absolutely no reason for this becoming adversarial, guys. Really appreciate it if you could throttle the hostility back and just discuss the topic. No need for vitriol.

Here's my reason for wanting carbide, and it's just this easy...

I use a carbide file guide for cutting in shoulders.

Using ceramic belts.

They don't touch the carbide.

Simple premise, no? Seems like if the front of the belt isn't touching it, I'll go out on a limb and bet that the back of it won't, either. ;)

I believe he is the first one to have used glass for a platten way back when
 
I've only gotten zapped by my glass platen a very small number of times, so I haven't really felt the need to search out a solution, but for all the guys suggesting grounding and lanyards and what not, I've heard several makers praise just a simple anti-static spray like you'd find for laundry and what not. Couple of spurts on each belt change seems to do the trick as far as I understand.

Ah!! Well that is pretty cool if that is the case! Deffinately a history to be proud of! :)

Right on!:) I was just confused by his post. But that isn't too difficult since my accident. (A little brain damage tends to confuse ya easier!:confused:)

I tip my hat to the person who spawned the practice of using a glass platen. If it was you Frank, THANK YOU sir!

I m not calling anyone out , just pure facts . I m not wrong David . Rex 121 have about 40% carbide volume and tungsten carbide plate have 95% carbide volume .Even plate with 80% tungsten carbide have twice more carbide then Rex , and that s why this two material is not even comparable . You can grind Rex121 and you can make knive from that steel , but be my guest and try that with cheapest carbide plate you can find:thumbsup:

Okay, thank you . I presented the glass platen back about the year 200 in the
 
Okay, sorry about this. I'm taking credit for posting the first thread on the glass platen on the Knifenetwork.com back about the year 2000 and that I also have been "looking around" for something better.Frank

Cumbersome and dangerous... I move around a lot when I'm grinding, and the idea of a shotload of wheels spinning around at 55mph with a lanyard attached to my wrist sounds less than appealing...

Agreed on making contact with the machine - eliminates the shock completely. BUT, when I'm working on a long piece, sometimes I can't keep contact with the machine, and then the ticking begins...

Using a work rest would all but eliminate this, I'll bet. Too bad I can do that. :p

If you can find a can of that clothes antic static spray give the moving belt a spray of a count 1 to 4 It will last quite awhile. Frank
 
Has anyone tried TiN (or probably more preferably TiCN or AlTiN) coated steel? TiCN is 3000 HV (87 RC) and AlTiN is 4500 HV (90 RC). It might actually be relatively inexpensive to do, especially if some makers got together to send in a "group buy" of platens to be coated.
 
It will not work kuraki . I have made some knives from HSS steel coated with TiN .It is very ,very thin layer and easy to scratch ...........

Did you ever try to grind Talonite ? It was only 42-49 HRC ?
