Liner Lock Finally

Make sure thumbob passes corner of bolster.

Scribe parallel lines along the edge.

Grind about a 45 deg on the edge prior to HT.

I use an acid brush and a bottle. Saw it somewhere.

Drilling thumbob hole into blade with a #44, 2-56 clearance size.

This one's getting a SS thumbob from TKS. These come with a buttonhead screw (don't know why), so I replaced with a flathead, so I'l lhave to countersink the blade. Make sure you get the right side. At this point, your knife can be a right hander or a lefty. I'll show you how to dress up the thumbob later.

Countersink the thumbob hole(get the appropriate side!). The 2-56 gets the 82 degrees just like the 0-80 did.

Making sure the flathead is almost flush. I like to leave a little high so I have some to grind flush so I get a nice finish/polish on the screw.

Finish the inside of the spine out to 400g before HT.

Layout any filework.

Filework under way.

Just making sure everything is done before heat treat... filework, touchmark, thumbob hole, countersink, lead in grind...

... almost forgot. Set disk sander table to 10 degrees and grind lockup area. It's easy to get the right/left thing fouled up here. the old saying, "measure twice, cut once" should come to mind.

With everything done that needs to be done before HT, I coat the spine and blade with Turco and let it dry while I heat up the oven.

Blade and spine going in.



I quenched em and will continue to shoot pics as the knife progresses. later
