Hey Friends!
This project has outgrown my "Jakes Workshop" thread in Maintenance/Tintkering so here it is as a WIP.
After playing with design ideas for a while I finally found the motivation to spend a few days on the working skeleton of this flipper. Since this is a solo and 99% manual project I won't be able to take as many photos as I'd like but certainly enough to get the idea.
There are a few reasons I wanted to build this knife, mainly because I have some specific ideas I'd like to try out which differ from the norms of construction but also just for the sake of having something I made.
Here are the basics:
What I Wanted:
- Light duty, thin, large flipper
- Smoothest action possible
- Fun to play with
What's Happening
- Titanium framelock or linerlock flipper
- Wharncliffe blade shape in Sandvik (13c26)
- AKS captured ball bearing pivot with hardened 440c bearings
- AKS hardened proprietary .250 pivot
- Hoback HRD (Hoback Rolling Detent) system
p
First I played with design ideas in Autodesk Inventor. I'm not proficient so this was truly a first step exercise
Then, knowing the shape I wanted, I built a "working" model from construction paper
Got some materials together.
Rough cut shapes, then refined and started looking for issues with binding, etc
First moment of truth, drilling and reaming pivot hole. Fitment was excellent.
Started main grinds on blade. This is when I realized I will never get a perfect grind with my 1x30
Time to cut bearing pockets in the titanium frames
Measured final gap and turned spacers from some stainless bar I had laying around
Cut recesses for spacer and stop pin hardware, then ground hardware to fit flush. Stop pin is still under construction in this pic
Finally bit the bullet and cut the lock. No fun
Did a partial hardening of blade so I could flip and play with the action while I wait for HRD detent to arrive without rapid wear to lock face. Here's where it stands until I find more time to work on it. Everything works well and it feels abnormally smooth. Temporary rounded face screw detent works just fine, and the centering is DEAD ON.
