NEAT! There is another factor you didn't mention. Life span of the cutting tool. With the Wimberly being basically touched up like a pencil being sharpened you get a very long life out of a small piece of tool steel. The other styles of grinds for the straight and traditional tool can certainly be touched up a number of times. But at some point a fair amount of stock must be ground back to start over. Not so with the Wimberly. Interestingly enough I made an AXA style holder that holds a piece of HSS angled similarly to the Wimberley for proper back and side rake angles. But mine sits along the leading face of a trapezoid shaped holder with its own dovetail that fits directly to the AXA post. It's the same idea in that I only have to grind the leading and end faces. For lighter feed rates I get the same curly strings. And for heavy cuts similarly straighter strings to the Wimberly. So there's more than one road to Rome apparently. My goals were ease of grinding and longevity of the length of HSS stock. And I got that on both counts. While I have some insert tooling I keep it for tougher alloys. The lion's share is done with my double angled face and end ground only HSS holder.
@@brucematthews6417 thank you Bruce. Those are some very good key points. Your custom tool holder sounds very interesting. I wouldn’t mind having a look at it, others probably as well. For me, grinding tool bits is kind of like doing painting you dread the thought of having to do it but once you get started, it’s not too bad. Thanks for the great information and have a merry Christmas 🎄👍
Interesting tests Dean. I’ve been using my shop made diamond tool recently, and getting great results. The Wimberly tool looks good. Going to check if they are available in the UK, but I guess would be expensive here. Have a great Christmas and a happy New Year. Cheers Nobby
@@GoCreatehms It was like a shiny object I had to have…Lol It actually seems like a pretty good tool Thanks for viewing and commenting. Have a merry Christmas. …
Interesting, I had no idea they made a lathe tool holder. Their photography related equipment is outstanding! May help to add a chip breaking feature into the top grind of the tool.
The shear tool bit is also called a skiver. It isn't something you see very often. I learned about them mid 70's but didn't hear about them again until 90's then your video . Seems they pop up every ~20 years or so 😁
@@hilltopmachineworks2131 Thanks Tom, i’ll check KBC Baldor wants insane prices for theirs other places have been out of stock. Merry Christmas and happy new year
I have considered making a wheel for my Chinese knock off tool bit grinder, but since there is potential danger if it fails I've put mine in temporary retirement until I resolve the issue.
@@CandidZulu I found a few affordable ones on the web, but of course they’re out of stock. So far the ones that are available are priced higher than what I paid for the whole grinder 😬
An interesting design but I'm not sure I see much improvement or benefit in use over the 'Diamond Tool holder' Tangential lathe tool.....certainly more grinding involved in sharpening the Wimberley tool.
Yeah, I made my own tangential tool holder. Simply hold the angled end of the bit pointing up to the grinding wheel face centerline to grind it and your done.

I'd love to see a picture of such a thing
If you use a bit of rubbing alcohol on cutting aluminum it increases the surface finish quite a bit. I tried it and it was eye opening for sure.
I keep meaning to try that...thanks for the reminder 👍
Happy Holidays !
Nice testing Dean. Merry Christmas. I use WMNG on my big lathe the majority of the time.
@@RRINTHESHOP Thanks Randy, it was a fun test.
Merry Christmas 🎄
Looks like the Wimberley is the answer to the question no one asked.
Young Dean your work shop skills and a equipment are coming a long in leaps and bounds , keep up the good work. Merry Christmas.

@@christophercullen1236 Thanks Kit, merry Christmas to you and yours..
Hopefully no major heat wave for the holidays
Cheers….
I think I got my aluminum oxide wheel for my tool bit grinder from Grainger several years ago.
I'll take a look , Thanks !

That's a very interesting test. It would also be nice to know how it preforms on the shaper.
I was thinking that too..
Maybe next Monday
Thanks Michael, Happy Holidays !
Very interesting, I quite like the look of that Wimberley tool if only because it's a little unusual.

Happy Holidays from merry old England Dean mate, have a great one 👍
@@RalfyCustoms Thank you Ralfy, happy holidays to you and yours 🎄🎉
Stumbled on your channel. Title sounded interesting, though half an hour felt a bit long for my breakfast. Found it worth the time.
Thanks.
Thanks Mike, It's always difficult to keep'um short.
Happy Holidays !
Happy Holidays Dean, you are a Tangent'Lman!
@@AWDJRforUA-cam thanks Al and you have a wonderful Christmas and happy new year as well…

Great video. Very interesting. Nice work mister

I have only used my shear tool a few times but it does produce a nice finish. And yes a very light cut at around a thou. depth.
The shear tool bit is also called a skiver.
It isn't something you see very often.
I learned about them mid 70's but didn't hear about them again until 90's then your video .

The shear tool is more commonly used as a surface finishing tool on the shaper.
@1crazypj yeah I first learned about them from Mr. Pete.
Thanks for commenting. Have a merry Christmas.
The lighting on the lathe is excellent. Ron W4BIN
Thanks !
On the diamond it used to be known as 1200 mesh but now it is referred to as grit. Industry refers to it in microns. Confusing yes.
I got wheels from KBC for my grinder.

This is somewhat similar to the “Diamond tool holder sold in OZ.
Used to stay in a student hall in Dundee called Wimberly the name must mean something to Dundonians!
@@pcka12 interesting it’s a name I’ve never heard of before.

Agreed, I do like the ability to regrind the tool without removing it from the holder.
Thanks for viewing and commenting.
Happy Holidays !
Yeah, I made my own tangential tool holder. Simply hold the angled end of the
bit pointing up to the grinding wheel face centerline to grind it and your done.
