Models for grinding HSS Lathe Tools

Thanks for all the help Mike! Great thread here. I'm going to need to download and print a new copy of the Book of Mike. :D

I also discovered that my honing is improved, I found a few shallow cuts on the thumb I used for testing the edge and cleaning the crud off so I can see the edge. Going to need to switch to a paper towel for cleaning. :) I knew I should, but I didn't expect it to be that sharp. My grandfather would slap me upside the head, he taught me sharpen knives safer than that.
 
Took a first pass. Not bad...

And my tool is apparently magnetic... :D

I almost always have small unintentional cuts somewhere after honing. My tools are pretty sharp when I'm done and I usually don't feel cuts; I just see blood on the tool. :(

CI induces a magnetic field when cut so yeah, the splinters will stick on like that. I use a demagnetizer when it gets to the point where it bugs me.

You need to play with the speeds and your tool's lead angle. There is a combination that will produce a really nice finish but still cuts well. Every tool is different so you need to mess with it.
 
You're not kidding about durability. I can see why you would like it on stainless. I can't tell any difference on the tool after the work. Not that it really did all that much work, just turning that center diameter down about 0.1". I did mess with speeds and angles and got a nice finish on the CI. The chuck is mounted on it now and running very well.

If people want to do the @mikey tool bit challenge, let's pick a material and I'll get some to practice on and grind the test bit. Would 4140 be a good choice?
 
4140 would be a very good choice. It is commonly used in a hobby shop.

1144 is also common; if you have not worked with 1144, you should try it.

Or you can go with O-1 tool steel or whatever.

T15 has a good amount of Tungsten in it so it can run at pretty high temperatures and is abrasion-resistant. The abrasion resistance is evident when you grind it, as you now know.
 
It took a few sessions tho the last 2 weeks, and quite a few re-readings, but I finally made it through this. Did missed the part 2 as it was info overload. What a fantastic thread!
Are we still putting pic up as it gets pass round?

Mikey you have don a really good thing on here.

If there any Aust on here I still lokking for some thing better then buy the HSS tools from https://www.ebay.com/itm/50pcs-3-8-...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

But the sipping is 2x the price so its a no go for me.

Thanks for the kind words, Tombstone, and yeah, we really want to see your tools! I hope they work as well for you as they do for me, and that they help you enjoy this great hobby.
