Title: Source For 2" Wide Felt Wheel?
Post by: darita on July 07, 2022, 09:45:12 PM
I believe some one here had a source for the 2" wide felt wheels that we use, however I can't seem to find it by searching.  Can someone please help?

I think this is what you're looking for: Duro-Felt Products

Check https://www.puruipolishing.com/product/10-inch-rock-hard-felt-wheel/

The wheel they offer seems to be the wheel Vadim (RIP) of Knife Grinders offered. Payment/shipment was absolutely not problematic.

Good luck

How much was that wheel, if you don't mind my asking?

It's interesting that they classify .65g/cm3 as rock hard, while Durofelt describes that as in between medium and hard.  Durofelt classifies rock hard as .80g/cm3.

I purchased a felt wheel from the first batch sold by Knife Grinders. Vadim sent me an apology, explaining that the first batch was not satisfactory. I noticed that the width on my wheel was changed from 50 to 45mm. I had noticed on KG's original video that the 50mm width did not allow adequate thread protrusion to properly secure the nut. By all means, investigate the felt hardness; however, start with a 45mm thick wheel.

That's it!  Durofelt.  Thank you.  Is the 2" thickness ok?

Based on Ken's post, unless it's designed for the Tormek (with an indent like the grinding wheels), or you can cut one?, then probably not.

The dimenion of the felt wheel is 250 mm dia. x 45 mm with arbor hole 12 mm. The unit price was US$ 75 / pc and 25 US$ for shipping.

The sales manager is Alan Chang (sales@puruipolishing.com).

Hello darita, a felt wheel of 2" width is too thick.

So this wheel is .65 density.  I that like the KG felt wheel or should it be .80 density?

Drilon, I appologize for having 2 threads going.  I watched the YT and see that .60 to .80 is the range.  Is there any way of knowing what KG used for his felt density?  From the Purui site, it seems possible to request your desired density.

One of the useful "Tormek helpers" I have found is a three pack of metric fender washers from my local hardware store. They are listed with two dimensions. The first is "12" indicating the size of the bore (the hole). I don't recall the exact number of the outer diameter number. Thirty three or thirty eight comes to mind. This dimension is not critical.

With a two inch wheel, remove the spacer washer on the shaft. In its place, use as many fender washers as needed to provide clearance for the felt wheel from the Tormek frame. The felt wheel is used dry, so having stainless steel is not required.

Incidentally, if you happen to have both a larger Tormek and a T4, these felt wheels will fit on the T4. While the T4 frame is smaller, the water trough is not needed with felt wheels.The area of the shaft used to hold the wheel is almost identical for the 250mm and 200mm models.

So reading your post, it looks like I can use the 2" felt wheels from DuroFelt, using fender washers?  What has been the consensus on these wheels?

darita,

the weight of my unused felt wheel form Purui Polishing Products C. is 1496 grams. The weight of the felt wheel from Knife Grinders after about 300 knives is 1472 grams. Colour, the "feeling" and the stamp "rock hard" are identical.  For me both wheels are the same product.

If Knife Grinders still would offer this product I for sure would not publish this information!

Drilon

Thank you.  Were Wootz still here, I wouldn't be looking around for another supplier.  Unfortunately, I became truly involved with my Tormek just after KG Wootz passed, but I'm still learning from his YT vids.

darita,
since I follow the sharpening protocol of Vadim:  CBN wheels > leather wheel PA70 > felt wheel 1µm diamond > leather wheel with chromium oxide I constantly get results better 100 BESS with all the usual kitchen knife steels. And this is just the prove that I removed the burr and I get long lasting sharpness.

Keep on studying!

I don't know, as I do not have a two inch wheel. The space occupied by the wheel is the total of the wheel and the spacer. Using a thinner spacer should allow more thread to project. Fender washers are inexpensive. Watch the KG felt wheel video. It shows the original two inch wheel in use. There is not much three showing, however, it worked, even if not up to Vadim's standards. Swapping a fender washer or two should solve the constraint.

Yes!  I'm trying the do the same.  I'm looking for the video on how to mix and load the Chromium Oxide.

Thanks to all.  I'm in the process of ordering a few felt wheels from Purui.  We're trading emails, as it's not possible to order directly from the site.  Thanks again.
