I felt like working on a challenge today. There are some unique features of the Speed Bump scales that I had to figure out. The torsion bar side requires a milled cutout for the bar to sit in. The clip side requires placement of the pivot and the clip. I haven't started working on the clip side yet.

I'm using lignum vitae because it is hard and stable, but was relatively cheap. I modified a forstner bit to work like a mill, and cut the recess for the torsion bar with a borrowed (crappy) drill press. The rest was simple drilling and sanding. Took about 6 hours.

I screwed up a few times on this piece, but it still looks pretty cool. The speed safe fires correctly and the stud lock still works (it contacts the steel not the wood). In a few hours the wood will start turning a freaky green that should look awesome.

Next up, the clip side.

When I complete these prototypes, I might make myself some nice ones out of cocobolo or blackwood or something. I'll wait until I'm back home so I can use my nice drill press, though.

NICE!!!!

You keep surprising me firebert. Very good work. The bump looks as good as ever with a wood scale.:thumbup:
 
Nice work. I just purchased the factory model today. It looks great the way you modified it.

I have to agree that you did beautful work on that handle and I like the flow - very pleasing to the eye.
 
great work again, i see you having a resident wood worker role here. two things, please post pics once it turns the "freaky green" and is the color of the steel a result of high polish and light or did you blue portions of it?
 
I like!

Yes, be sure and post pics as the color turns.


Trivia: The U.S.S. Constitution's belaying pins are made of lignum vitae, and seldom need replacement, even in a saltwater environment. Also, this wood does not float; it's denser than water. ;)

Click to expand...

so basically, if he were to be walking near a river and for some reason this knife fell in, he would be doubly screwed? :p :D :cool:

post pics! and alot of them! esspecially when you get the new wook scales done and when it turns that green!
 
Ken's handle designs are such a joy to sculpt. The curves just flow perfectly. About the blade. I'm a sucker for shiny things. I sanded the bead-blasted finish off.

It's funny, most of the wood I work with doesn't float. Cocobolo, blackwood, some ebony, snakewood, pernambucco, and others don't float in water.

You can see the color change in progress here. I'll let the handle bake in the sun the rest of the day and we'll see what happens.

The metamorphosis is nearly complete. Doesn't it look strange?

Anyone have ideas for drilling a hole for a hexagonal pivot?
