Most knife makers don't make folders. I hope to change that a bit. This process uses hardened drill
template patterns to help in the fabrication of a liner lock. The goal is to make available the patterns, that
guys who are new to folder making, can use. There may be a blatant "buy this" from us kinda thing going on
here, but I'll try and keep that to a minimum.

Metal:
.125" or 1/8 CPMS35VN for the blade - this should be slightly oversize and you bring it to thickness
.070" Ti for the liners - I've done these in .070" up to .125" I'd suggest .070" for your first.

Parts list:
(2) 3/16" thick g10 or Micarta(tm) material for the scales
(1) 3/16" thick g10 material for the spacer bar.
(1) 3-hole Ti pocket clip
(2) 6-64 disc pivot heads
(1) barrel pivot threaded 6-64 ID and 3/16" OD"
(6) 1/2" 2-56 button head screws
(4) 3/8" 2-56 button head screws
(1) 1/8" stop pin
(1) 2mm ceramic detent ball
(2) .015" thick PB washers in 3/16" ID and 3/8" OD
(1) thumb shredder thumb stud
(1) 1/4" 2-56 button head screw for thumb stud

Tools required:
caliper or micrometer to measure your parts and metals
vice grips style pliers
surface plate or machinist parallels (or both) or something dead flat to check the metal
layout fluid
carbide scribe
drill press

#49 drill
#13 drill
3/16" drill
1/8" drill
1/8" reamer
3/16" reamer
#19 drill
#42 drill for through holes for the 2-56 screws

Dremel or other rotary tool with cut off wheels
grinder of your choice
disc grinder to debur is optional but darn nice, other wise sand paper on a flat surface
a half ton hand arbor press or a bench vice to straighten metal if need be. (There are other ways to straighten metal also.)
2-56 tap
tapping fluid
countersink to debur holes
