Here we have about a 5.5" long chunk of 5/16" D2, HTd and flatground within .0002" of an inch. This is used to insure the liners are flat before you mill the tang relief. After the bolsters are soldered on you check it again before you put the handle material on. If the liners are nice and flat before you put it together, you will have a very fine working knife.

Oh yea, that's a knife I am working on for a forum friend that really likes yellow bone. :D It's a 4.5" Bose Backpocket pattern in D2.

Wow! You da man. I've not even contemplated trying a folder.
 
Those are really nice fotos of what's going to be another great folder, Kerry.

Yellow bone....reminds me of peering into those knife display cases in the hardware stores as a kid and being captivated by a yellow-handled knife where before they had all been in red and brown. Good choice!

Is that an old B&S micrometer? Regardless, I bet it has a neat history, what with those initials carved in it. A treasure. Someone else will have a treasure soon in yellow bone and steel.

Thanks for sharing. :)
 
Man I"m sorry I missed you. I was there when Tony opened them up...they are dead flat! Those will certainly come in handy. Oh...... the knife!.... it's nice too!

That's a beautiful grind:thumbup:on the blade! You have me intrigued:confused: What is the knife going to look like, when complete. Post a picture when you get it finished.

The mic is old an Starrett that belonged to my grandad. I needed a mic that had .0001" graduations so I asked my dad if he had one that I could use. He gave me this one, which was his dad's that he used when he worked at Douglas Aircraft in Los Angeles during the WWII years. "CAP" was my grandad's nickname.

Thanks Brent. Oh yea, you gotta have something flat as a standard if you want to make a slip joint that looks good and works well. Otherwise it's just a guess what the knife will be like when it is finished.

Thanks Fred for the nice comment about the grind. 'Em ain't easy! ;)

It's going to look like this one but with a thong tube and yellow peachseed jigged bone, and federal shield. Also, I milled a crescent pull in this blade where the other is straight. Uh....guess it won't look much like that one after all LOL.:D Well it's the same dang pattern anyway. :p

Well Kerry,
I 'd really like to receive that from you at the Blade Show next week if you have it done.....

The problem with that is I'm not the forum friend for whom you are making the knife!

See ya in Atlanta,
 
Tony told me I should take that with me to Atlanta so my friends can "chicken eye and coon finger it". :D I hope to have it and another one finished by then.

How do you use the bar?

Just use it as a reference to make sure the liners are flat. Lay a liner on the flat block and check between them for gaps. Straighten as needed till you don't see any gaps. Simple but effective and important if you want to make a good slip joint.
 
Kerry,
That folder looks great.
I know a few guys that just use a slab of granite for checking flats. I suppose what you have is a little more precise. Do you have a mill that machined that flat or did you aquire it from a machine shop?

There was a certain chain of events to get the ground block. We started with a bigger chunk of 5/16" D2. I cut off 2 pieces(we made two blocks) with my Jet band saw. Tony Bose cleaned those up, HT'd them and sent them to a friend that has a surface grinder.

A marble bench block will work but they are kinda hard to hold up to a light:) With this you can really chicken eye that dude.
 
Lookin good Kerry and you're right, flatness is most important for a good slip joint or any type of folder for that matter.
