LINERLOCK - WIP

I am keen to get comfortable making framelock folders so thought that sharing some WIP would both help me to document my process but also allow comment tips and critique so please let me know your thoughts as this goes on. It won’t be quick as I will need to get a few blades ready for HT as I will be send them out and cost is same for 1 as it is for 5 blades. So it will be a couple of months I think before I get to finishing stage but I figure that speed is not the name of the game here and time in the shed is limited both by the weather (heat) and life!

So I started out with paper and French curves to work out my design, using a pin for pivot point and making various changes until I think I have a design that will both work and is in a style I like.

Next up using my templates I stuck them to the titanium for the frame and I’m using some RWL34 for the blade.

I cut the backspacer from the same blade steel to give me a spacer with same thickness as the blade for initial design and then will use this as a template for a final backspacer most likely G10.

Blade is drilled with #14 and the reamed to 3/16 777409E3-79C7-4F57-9AEF-1A1456A77B96.jpeg

I’ve been having trouble sizing and posting pics so please bear with me.

Anyway, All cut out and starting to get the idea of how this may look. The idea is for this to be a front flip opening knife so you can see that there is some protrusion of the blade tang at the front of the scales. Screws are 2-56 tapped in the Ti - no broken taps this time as I have my technique sorted and moved away from hand tapping and using a cordless drill which seems counterintuitive but works great.

Next up is working on the notch for blad to close when stop pin is installed and to open to desired height.

And open position

Now it’s time to cut the lock bar. Set my drill press to highest speed it can go and using a metal cutting disc I was able to cut a decent slot with the liner held in drill press vice. These are much better than the dremel version I used previously - I could cut a couple of locks with one disc I think.

I have also drilled hole for the 2mm ceramic detent ball to sit in by the time I took the photo.

Bending the lock bar using a piece of wood with slot cut into it. I used this method to try and get a more gradual bend along the lock bar rather than applying heat to the back end and bending in one spot. I am really not sure which is the best way to do this so if anyone has some advice I would love to hear it.

And the result

I’ve just change the title of this thread - I had it as a framelock but it is a liner lock - sorry if I caused any confusion.

Looking good, IanF! I'll be following along with you. You asked about bending the lock bar. I do it the exact same way that you do.

Looks good so far Ian. you might want to make bending the lock as one of your last steps though, I know when I build them I end up putting it together and taking it apart countless times. it makes those steps easier if the lockbar isn't under tension, at least I found that true for me.

Thank you for the comments Brandant and Steve.

Steve I bend the lock now to grind the face of the locking surface on the tang, I.e to set the lock up. I probably should get my scales all mounted etc before this step but I guess I feel that if I can get to the stage of the blade opening and closing to correct position and the lock engaging as I want it then I am well on my way. In other words these are critical steps that I am most likely to mess up!
