So was I so I thought I'd try gluing two pieces together and cutting two liners out at once.
Worked great!
Didn't have any of the chatter and hardly any of the hot chunks flying off at me.
I used my trusty Daps Weldwood contact cement and after I glued the two pieces together I drilled all the holes. Then I used a couple drill bits to help keep the pieces lined up.
Once I had the liners cut out I cleaned them up on the grinder and took a freshly sharpened kitchen knife that I use in the shop and carefully separated them. The glue rubbed right off since I had sanded the ti down with 120 grit prior to gluing.
Just wanted to pass this along.
Take care folks!!

Hi Michael. Johnny Stout taught me that procedure using super glue, works great also. I seperate the two halves by heating the Ti with a propane torch, they pop apart. I'm no expert (that's for sure) but when I bandsaw Ti I use an old metal cutting blade, at high speed. I've heard it called friction cutting, but whatever name you use, it sure cuts it fast. It'll make the fillings in your teeth rattle though, and eye protection is an absolute must, but it works for me.
 
I was super gluing a couple of pieces together also but getting the old glue off was a pain. So I've started drilling and tapping two extra holes in the liners where they won't show on the finished knife and screwing the two pieces together to profile w/ band saw and grinder. Lots easier, at least for me.
 
I have been doing it farily similar.....I rough cut two plates at the same time to get it down in size ...I keep the two large plates clamped together with kant-twist clamps....then I drill the pivothole and ream...I do this with the pieces seperate...then I insert a pivotpin and drill one of the backspacer holes and tap one side....put a screw in it and drill and tap the rest of the holes....now I take it to the saw again "all screwed up" :D
 
Lol Jens!
I spoke with Kit in the chat room last night and he set me right on this one!
He does it similar to Bill and Jens.
He drills all the holes in both liners with the tap size bit then taps the pivot and back spacer holes of the lock liner, which he calls the split side. Then he drills the pivot and back spacer holes on the non lock liner with the thru bit and screws the two liners together.
He does this after cutting the liners out but I don't see why it couldn't be done prior to cutting to prevent the problems thin ti gives us on the bandsaw.
Thanks again Kit!!
I'm going to print up an extra copy of your tutorial for the shop.
Tips like this make so much difference in knife construction!
 
Some of you may already know this but I use 24 or 28 TPI bimetal blades on thin titanium, they cut very good, last a long time and don't rattle you brains out :D
