Moen Hardcore Knife Jig?

how do you adjust the angle? just by adjusting your work rest? Personally if I were dumping money into a jig it would be for Don Dentz's DD work rest and grinding jig.

Adjustable work rest is MUST , right ? If so , WHY I would need to build that complicated adjustable grinding jig too ??

Versus a couple hundred bucks for a water cooled platen? How is the air cooling more effective with regard to belt life and blade temperatures?

I have have done wet grinding & it can make a Fing mess! Lots of people don’t want/like it. And especially for carbon steel lovers. A lot less chance of rust problems

Try this ................. I used PC processor Al cooler on my two wheel grinder .In 2 x 72 grinder you can use two cooler like this . No need for forced air in cooler . And IF you manage to build heat / can t touch platen with hand / I will buy you that Moen :)

I grind everything after HT on a regular flat platten. I did a few cpm154 chefs knives today, leaning in as hard as I can on a 36 ceramic running 5600 sfm. I don't find dipping them in water as needed to be that much of a pain.
I like the idea of that platten for finishing, but not for what it costs. I've halfway considered making my own clone, but I'll probably just get a second platten faced with felt to do the finishing with jflex belts on.

Yes it is, however work rest tables are kind of a pain to adjust and only offer gross (large) adjustments. On the DD grinding jig it's super quick/easy with a slight twist of your finger for angle changes on a micro level. It's not good for every grind, but it's superb at some and lowers the mistakes =)
 
Just for clarification, I’m not talking about the platen assembly. While it seems pretty darned nice, it’s just not gonna happen. The grinding jig is what I was looking at. I’ve not really ever used a jig for grinding but from what I understand (and can definitely see) a problem can be found when having to take off the knife from the fixture and re-securing it. That can end up with not completely symmetrical grinds. The hardcore is certainly nice since it swivels and is therefore the same on both sides.

Natlek-
I couldn’t understand a word in that video, but the demonstration was certainly easy to understand :). It’s definitely a good, cheap possibility. I could see that being particularly helpful for the style of knife he’s grinding. I could see it more challenging to attach a variety of blades to it such as folders. If you can’t put a hole in the blade where it’s needed, that will make it a lot more difficult. That was one of the things that looked nice with the barcode-it looks like it clamps on to the blade wherever you want it.

Matlek,——————Looks like a great idea! I hope it doesn’t work though because my main idea for possibly buying the Moen Platen is after grinding knives etc for 22 years my hands are feeling it and at this rate, if I want to be able to wipe my own ass in another 10 years, I’m going to have to move to a good jig setup to lesson the wear & tear on my hands!:D:p

Yeah, I don't know man I'm just asking how or if it's better at cooling than a chilled platen. I'm not trying to shoot the thing down.

Didn’t say you were trying to shoot anything down.. I bought one of Nathan’s chillers for my KMG but I never really liked that machine, for other reasons, so I sold it. At the time that was the only machine he made them for. Just wondering if you or anyone else knows of someone that makes them for the Tag or Hardcore!!

what language is he speaking?? I didn’t catch one word, while I’m not a linguist by any stretch! I can usually pick up a word or two and at least have a idea what the language is..
OK, I don’t think anyone makes a chiller for a Hardcore or my Tag 101...??

I do not understand either, just a few words here and there :) language is Turkish .
 
I'll have to build my own chiller for the Bee, but its on my eventual list. It'll be a bit of an odd one to work around the design of the grinder and platten, but it'll do the job.

It’s air cooled from the back of the platen. The word revolutionary comes to mind. The craftsmanship is beautiful as well. It starts off as a massive chunk of aluminum before it’s machined.

it is also not riding directly on the platen and eliminates belt bump as well leaving a very nice finish. I watched Jerry do a finished grind in about 20 minutes and that was with him stopping to talk about what he was doing.He went to a mirror finish with three belts.
Really it’s a trick set up.

I am hoping someone has some experience with this jig? I’d been talking with Bing about it shortly before he passed away... He spoke highly of it when I mentioned frustrations with some of my bevel grinding. He actually said he wished he’d found the jig earlier on and I could see how he used it when I went down for the folder class. Sadly, that won’t happen and I thought I’d see if anyone here had used one?

From the few videos I’ve seen, it appears to work rather well, but I know things can have a down side. I can’t help but wonder about the post heat treat build up of heat and how one cools it down? With the blade in the fixture, you can’t just dunk it in the bucket... Anyway, figured I’d see if anyone had some thoughts to share. Thanks.

Not sure if you've seen this one or if it helps ya out at all, but I remembered seeing this video which shows Todd Begg grinding a blade from start to a mirror finish using that jig. It shows him just dunking the whole jig in water then drying it off with a quick blast of air from a compressor.

Tru Grit has the Moen Hardcore in their office, it is well made and very precision.
The moving rubber belt over the carbide platen with the fan keeps things cool for sure.

But, I find it interesting what lengths people will go to do a flat grind.

I use a TAG 101 and have the chiller set up on it But it would have required drilling and tapping new mounting holes in the c plate or buying a new one from Nathan .. I opted for the latter. I have a sweet settup now, with 3 chillers, 1 for each platen (36" radius, end radius, and regular flat)
