How to make a liner lock folder - need guidance

Appreciate all the info, have read Bob’s book a few times, along with few other books, bought a few of the videos from Chris Crawford and taking a class with Rick Dunkerley next year but hope to attempt a few before I go. just need to get the supplies and the shop time. (Travel a lot for work so usually more time to learn while in hotels then actual shop time)

I understand the difficulty and expense to acquire Bob's book, but I'll still say it's still good advice. Understandable if you can't find a copy reasonably, but in case you ever get the opportunity...You def will benefit from some resource that discusses folder geometry, locking face angles, etc.

Also, I'd recommend ti because I think its easier to achieve good results than stainless. The lock is a spring, so I'm not sure how you'd heat treat 420 in a coal forge reliably - doesn't mean you can't, I just wouldn't put myself through that. I have also not had good luck with discount titanium for to warps or bends which invariably put pressure on the blade at the pivot and kicks the tip off center. I do have a buddy that uses whatever is cheapest, I just got frustrated with it.

Best of luck!!

Hey Tito, thanks for your input, I will at some point get the book, I may have sounded a bit anal about it but I do read a lot of literature on the things I like so it will at some point reach my reading list. Youre right about stainless im going with titanium!

So taking into account the input in this thread and finding some more instructubles and videos online I feel a little more confident with crafting a folder. Im a little confused still about certain things like the backspacer and detent ball. Can i use the same steel as the blade (same thickness) for the backspacer? This doesnt sound right as i write it down, im supposed to go larger right? Also realized from a few tutorials that i need to also thread the screw holes unless i go with hammered bronze rods. So i can only find 1mm thick titanium in stock, so im thinking of doing 1mm titanium with 2mm of g10 as well as a 4-6mm of o1. Now the tricky part for me is figuring out screw hole sizes and generally part sizes to put it together.
 
The backspacer thickness has to equal the blade plus the pivot washers. Your dimensions seem good after I convert metric to standard...eg, .04" liners for a .125-.156" blade. That should work. It's so late, hopefully someone else will come in....
