making the backbar

today's final picture

and a little video, the knife already works quite fine, needs just grind on the blade, scales, and open-state lock, finishing, and should be done....####, that's quite a lot of work

Question, how big of a spring did you use for the button? The ones I've got in the shop seem to be too long to hide in a reasonable sized bolster. Thanks for any help. Ryan Minchew

mine are 1/8" in diameter, and about 1/4" long-the button has a drilled hole from the underside, and the spring gets hidden there.

Anyone started on their folder yet?

I'm going to pass on this one, Papi.

I don't like the idea of having a counterbore in the blade pivot area.

I've enjoyed your WIP and am looking forward to seeing your finished folder.

Thank you.

You don't have to

if you feel uncomfortable doing the counterbore, just do the same thing as with the bolster. I didn't do it like that, because my blade is very thick on this one, so it wasn't necessary. But you can create a channel around the blade pivot hole, making room for the spring, and leaving enough material to contact your pivot pin at the same time

Papi could you send me the scale design of the knife where I can Get started on it as soon as I get finished and can after my shoulder surgery. I will need to get the spring, button, and some other materials necessary.
Thanks in advance,

Sure thing, i'll try, but i need someone to draw is for me, cause i'm useless with computer

But i'll post it here ASAP

Thank you Papi. I joined in too late to follow step by step but I find the design interresting. I will try it some time.

To answer the question, I haven't started yet. I plan to soon, very soon. I have a specific plan for this knife. My son is currently going through the Ohio State Highway Patrol Academy "boot camp", a 6-month very intense training session for new troopers. When he finishes, I want to present him with this knife. It'll be my first auto. Actually I think I'll do all the machining but let him put in the spring if he so chooses.

That is a great idea, i'm sure he'll appreciate that

I hope you'll be succesfull, I have to get my ass to the shop and finish the knife, but it's been so hot here last few days that all i'm able to do is lay next to pool and bath in my own sweat

really not a good weather for work...

yeah i know what you mean, i have never liked hot weather,but after the bypass it just stomps a mudhole in my butt. so i wind up working 20 min. and go inside.

papi · #45 06-16-2009, 04:47 PM

Yeah, too hot is never good

But i promise i'll get the knife finished by the end of this week
