I'm looking for some advice from any custom folder makers. Specifically frame/liner locks. Ive successfully completed a handmade back lock and want to give a frame lock a shot just to see if I can make one with the tools I have. I currently only use a 2x72, spindle sander,, drill press, dremel, files, etc. I've got my template made and pices cut out of 3/16" cpm154. I know I can use the cpm154 as the spring tempered back to 45-48hrc. My question is with my original stock being so thick how thin and how long should the spring section be? Attached a pic of what I have so far if it shows up.
