Hello fellow knife doggers!

I recent purchased a few of these newer Norax Ceramic U936 belts and would like to hear your comments on how you best utilize them for finishing?

I may have tried a few years back but I they were non-ceramic or these ceramic U936 belts.

I have the 100, 65, 45, 30 grits.

So? Light pressure? lots of pressure? Fast or slow speed? I just want to get a nice clean even bright satin finish.

Any hints from you other makers that have used these for a while?

Thanks.
 
I use them extensively as the stock-removal per dollar is excellent with them.

Using the medium speed on my grinder, I find heavy pressure is best - the 45x and 16x micron have a tendancy to glaze with light pressure. I go from 100x to 45x to 16x then a scotchbrite belt for a very nice satin finish.

They have limited utility elsewhere and perform best on blade steels, I've found. With so little flex even contouring bolsters is an application better served with other belts.
 
Most of my grinding is done prior to heat treatment - but due to the life of these I find that if I'm working extensively after heat treatment this particular belt grade works well.
 
Thanks Frank,
I grind and then finish of course Post HT.
So go from a 120 grit Ceramic belt to the Norax 100 to 45 to the 16 and then Scotch it.
Any one else have some experiences to share?
 
My use isn't a lot different, Lawrence. I grind all my blades after heat treat . They are folder blades and biggest go 4" in the bevel ,grinding area. I start with the 120, 65, 45, 16, 9,6, I have just yesterday done the 120, 45, 30, 16, 9,and 6 and will give it more tries. I am able to get the blades down to you can quickly use a black emery compound on a buff to clear the very fine scratches left, and then go to a green or white, or do just a bit of hand sanding with first a 600 and then 800 and then go to the white or green. Perhaps a little no scratch pink. I find these belts to be strictly for metal work. There is a 36 grit ceramic out there I get from Canadian Knife Maker supply who has all of the U936s. I don't know anyone else that does. I don't have a surface grinder so when I'm into thickness sizing that 36 is first up. It is saving me a ton of hours and does seem to be standing up extra well.

Hello Frank,
Are you referring to those Black Norton 36 grit belts? I had couple of samples in 36 & 60 and those sure did cut and last! My supplier here in the USA doesn't want to stock any because it would cut into his blaze belt sales.

Thanks.
 
Yes, Lawrence.
You wouldn't have any problems ordering out of Canada at Canadian Knifemaker Supply. The exchange on the dollar would give you back about 4cents on every dollar you spent and there wouldn't be any custom problems. As well Marlyn and Rob Ridley are very good people to deal with. Frank
 
Frank,
I may do that soon. Rob is a great guy. a couple of years back he sent a sample of another kind of belt to me to see what I thought of them.

Thanks for the props Frank, but I have to damper them I'm afraid. Our liability insurance won't allow us to sell outside Canada. We keep looking for something, but can't find it. A few weeks ago, a company quoted us based on 5% US sales. The premium went from $1600 a year to $6000 per year!!!!! We've seen better quotes, but nothing that would justify the huge premium jump.

Apparently the insurance companies live in fear of what they call "the most litigious society on the planet". Of course, that's an exaggeration, but we are in a position that we require liability insurance and the view to the South seems almost universal. :-(

Always open to suggestions. :)

Rob!
 
Rob,
Unfortunately there is one lawyer for about every 1000 men , women & children here in the USA. I have always thought that we should make lawyers our number one export to put other competing countries on a level playing field, but in my heart I know that is just to evil of a thing to do!:biggrin:
 
pricey belts, but worth every penny! i use them for post heat treat cleanup, work great, and are the lonest lasting belts i've ever used

As mentioned in this thread and several before it, I also use these heavy blue-back structured ceramic Norax U936 belts. I had to order a large quantity of the 3 grits I utilize from my local American Welding and Gas distributor who's the Norton guy around here. I've got 100x, 45x, and 16x micron grades available, the price to me is $14 and shipping for one coiled up in the 2" deep small flat rate box would be around $6 if anyone wants to give one a shot - this isn't a sales pitch I'm just wanting to let everyone who might be curious try these out.

Frank,
I got these Norax U936 belt from www.trugrit.com Ontario California for around $10.00 each. If you ordered a few you could save yourself a few dollars and maybe get some other belts?
 
That's a great price for them - My $14.00 from my particular supplier was due to the volume, I imagine Trugrit purchases them in much, much greater quantities hence the lower pricing. The cost difference is no matter to me as I have them immediately available during working hours, and no time spent ordering or shipping for replacement. Thanks for the other option!
