Mike... I'm really interested to see how yours plays out.
Ryan... I'm really interested to see how many entries you have for this build-off when all is said and done.
I've been plodding along here. I have a couple of photos from this morning.
This first photos shows the way things looked when I went to the shop at 8:30.
Some of the key items I completed since my last posting:
- Soaked heat-treated blade in vinegar over night to remove any vestiges of scale and give a VERY rough preview of hamon.
- Lapped the blade pivot holes to a snug fit with the pivot bushings. The fit that I look for is one where the bushing can be pressed in easily with my fingers with just a bit of resistance. After some lubing and a flipping, I find that this gives me a smooth action and minimizes the final blade play.
- Lapped the end of the pivot bushings to be slightly proud of the blade ricasso. "Slightly" is achieved by lapping, assembling the handle/pivot, checking pivot tightness and blade play, then repeating the process until everything fits together. You can see the Knifedogs Pivot Lap that I use for the bushings on the left side of the photo. You can also see one of my new HF torx drivers. I lost my old one and decided to buy a few more... just for fun.
- [Bite handle only] Drilled and tapped a piece of 0.15" titanium for a spacer. (That's the large chunk of Ti with the two holes in it.)
The next photo shows where I left off after the hour that I was down there this morning.
You'll noticed that the spacer and the stop pin have both been rough-fit into the bite handle. You can also see the safe handle bushing in the pivot hole. I have temporarily pinned the safe handle sides together for some additional grinding around the pivot area. At the bottom of this photo, you can also see my home-made pivot grinding/lapping plate. It has reamed holes in 1/8", 3/16" & 1/4" for grinding pivots/pins/bushings/screws/etc. to length and makes sure that they are kept square.
My next steps are to make sure that both handles get installed and operate cleanly. This means:
- Additional profile grinding to both handles.
- A spacer for the safe handle.
- A latch-pivot/spacer for the safe handle.
- A stop pin for the safe handle.
- Fine adjusting to the blade pivot stops for open and closed positions.
After the handle operates smoothly, I'll:
- Build a pocket clip and mill a receiving area for it in the bite handle.
- Clean up, polish and etch the blade.
- Rough contour the handles and begin finish sanding.
- Install inlays (maybe).
- Complete finish sanding on the handles AND
- Fit and install spring latch.
It sounds easier than it is.
I hope to spend some more time in the shop in the next couple days.
