As soon as I saw the picture I thought, "Isn't that shield on the wrong side"I realized that I inlayed the shield on the wrong freaking side!
Technically, yes I could and just make it a left handed knife. But this is all just for practice so I can learn. That knife will be funny to look at one day down the road to remember my learning experience. Honestly, losing the knife into the buffing wheel was equally disheartening Total rookie move!Eager to see the next part of this tutorial Darren!
The rehandled RR looks great. Can you cut a new nail nick on the shield side?
Thanks Ed. I can see that and have had to consider the thickness of the handle material w.r.t. the thickness of the shield. I could potentially inlay the shield such that it is only partially in there...then grind off the extra if needed. I think for harder or thinner materials I might take that approach...simply to avoid having to route out more materialYou know Darren, back in the day not all knife makers/manufactures completely set the shield into jigged bone or stag covers. They would lightly router the shield cavity and actually set the shield partially on top of the covers. It's hard for me to give a clear explanation but if you ask some builders they can explain the procedure completely. I have several knives with shields that are proud or partially proud of the covers.
Nice work so far.
NOT a "ROOKIE MOVE" - having something get away from you on the buffer. All too common. Yes - the rookies are more likely to get bit but even pros can, and do, get caught off guard. The buffer and edge tools (in particular - but also nearly everything else) are potentially lethal combinations. Any operation on a fast turning buffer requires complete attention to the task and situational awareness - no phones, no tourists, no loose clothing or other danglers or gloves but certainly wearing safety shields.
Darren, waverave - you know all this. I'm just talking out loud for others who might not appreciate the risks associated with buffing wheels - whether grinder motor types or even the dremel types. Those little guys can wrap around the wrong side of a blade and in a second your knife is airborne. You are lucky if you only drop the knife.
Anyway - your work is inspiring. You are a good teacher and your modesty is endearing
Take care.

Nooooooooo! Do everything you can to get the right sized pins or go the next size up and file down the pins. If you drill the holes bigger you can end up changing the tension on the spring and weakening the pulls. I tried to drill out a spring to corespond to the size I drilled the liner but it heated up the spring until the metals color changed which I’m sure messed with the heat treat on the spring (I was waiting for it to break every time I used it) the bit broke off in the spring and wasn’t easy to get out and it barely made a dent in the spring. They sell drill bits on amazon that are in .05 mm increments (you have to buy 12 but they aren’t that expensive) I got 2.15mm ones for gec 15s and they seem pretty close 2.2mm might be right on the money. In my experience everything just works better if the pins are as close to original as you can get.Go ahead and drill out the holes at this point and make sure all your pins fit properly. You may need to drill them a slightly different size depending on what you have available. In this case, I had to drill out the pivot pin a little, same with the center pin and then I had to drill out the hollow pin hole as well. Keep in mind, that by doing so I also had to drill out the pivot hole in the main blade and the center hole in the spring (both hardened steel).
but another lesson learned for me when working with bone...it is BRITTLE! Aside from that and the smell though, it is very easy to work with
...to be continued...
Message received I didnt consider grinding down the pin but not sure how that would turn out. It was basically a micron bigger hole I had to drill and it didn't take long or heat up much.Nooooooooo!

I put the swayback project on pause until I get more router bits...so I filled the time with another project I've been wanting to try. I'm a big fan of the Peanut...but just don't use the secondary blade and I always find myself wishing for more variety in configuration. So I am converting one to a single blade bare end with a hollow pin (for a small lanyard...fit right it will provide additional leverage when grabbing and holding the knife). It has proven to be a bit more involved than I anticipated but not bad at all...every work-around I tried has worked (so far).
Taking a Peanut apart is relatively easy. Now that I've done a few it is much easier, in fact. I am almost at a point where I can take a knife apart and reuse the material if I want.
Standard springs, liners, etc. on this one...as you'd expect.
The first thing I had to do, however, was modify the spring to fit the hollow pin I am planning to use.
This is what it looked like originally...

...and this is what I had to change....

Interestingly enough, it was the RR swayback project that gave me the idea because that is how the spring on that one is already shaped (roughly)...designed to simply rest against the hollow pin and not necessarily wrap all the way around it. With the main blade in place and the spring under tension, it sits firmly against the pin.
I decided to try bone for this project so I could get a feel (and apparently smell...whew!!!) of it. Seriously though, if you've ever had your teeth drilled at the dentist and know that smell...that is exactly what is smells like to work with bone.
Here you want to cut the piece rough but get the fit against the bolster snug...then glue to the liners.

At this point you can rough shape the edges to the liner and start sanding things down. Once the thickness of the scale is correct, you are really just rounding off the corners and making sure the fit at the bolster is smooth.

Got one side done and feelin' pretty good...with appropriate battle wounds for this hobby...

The very first thing I noticed when I took this knife apart was how easy the bone scales cracked...it should have been a warning! I ended up cracking the other side. It was just one or two tiny little whacks too many apparently. Luckily, I have more of this material (discount undyed bone) and it won't take long to redo it...but another lesson learned for me when working with bone...it is BRITTLE! Aside from that and the smell though, it is very easy to work with

Id like to find other size pin stock to match some of the oddball sizes I am coming across.
Ahhhhh...that seems like the way to do it.I use a hand drill and a file to do it at this point...
