Copper Corby Bolts?

Thanks Phil,
I have contacted several machinists, and will let you know what I find. I will make a good sized contract order and put them on the exchange if this pans out.
Sit tight folks, and I will post as I get info. I might even contact some folks in China and see what a big order would run, but I would rather get it done in the USA, even if it was a bit more.
 
Just to let you guys know,
The BossDog over on Knifedogs is making up a batch. He runs USA knifemakers . I will keep you chaps posted on the pricing and what comes up with my inquiries. Whatever will be the best price and simplest ordering would be the logical choice, so we may all end up getting them from him when he gets a batch made.
 
Great! I had asked Tracy about that a while ago. Glad to hear it's in mo. Thanks Stacy & Tracy!
 
Thanks Stacy and Tracy. Please go with an American or Canadian manufacturer.
 
Tracy has the order running. It will be available in 2-3 weeks on his web site. I'll post when I hear again from him that they are ready.

Thanks, Andy, I had forgotten about Jim at Pop's. I'll give him a call.

One problem with machining copper is it is the gummiest stuff to work. Many machinists hate it with a passion.
Dave, if Jim will make a special order in Copper and in Bronze, I would go in on a part of that run. In the 1/4" size could use 100 in bronze and 50 in copper.

If you want, I'll give Pop's a call tonight, and make a bulk order for us. Let me know what size you want and in what metal.

I'll see him at Harrisonburg in six weeks. If he can make us a batch by then, I could pick it up and pay for it all, and send you your part.

Yes we do....But Tracy is a sweet talking SOB....
 
I betchya a nice old Brown and Sharpe Screw Machine could knock em out slick as a whistle... Let me know the pricing on that as well please :)
 
Talked with Tracy and with Travis at Precision plus. Tracy has sweet talked Travis into this order, and we have combined the order into one, with Tracy handling it.

For those who haven't worked copper on a lathe or mill, it it very hard to do. Hardened stainless is a walk in the park compared to annealed copper. A screw machine would be fine if it is set up for an oil flood. The taps will have to be different,too. Believe it or not, copper is rough on carbide tooling.
 
Great to hear Stacy, THE 1 and only time I tried to mill the slot on a copper guard, I couldnt believe how gummy it was. it literally wasn't cutting (much) but rather moving out of the way, best way to describe it was a plow in the ground. same action!

It is a pill.

The taps will be thread forming taps.

There is nothing fun about machining copper, in general. But threading it is just special.
 
woudl part hardenign it help out in the long run. say hammmer rod one order of size smaller in a rolling mill and then cut it

like Al the harder it is the better is works
or am i all wrong
 
Are they doing some sizes up in silicon bronze too? I actually believe there would be more demand for that in the long run, or at least a steady buying base for it.
 
You're right Phil, several folks asked about silicon bronze...

I will work in some silicon bronze also. It will be the same set up, just a material change. It's simple to work in. We already have the G-code done.

Precision Plus, can you machine them so the threaded part doesn't extend deeper than the shoulder? Sometimes on thinner handles I have to grind off a bit of the threaded parts on each side to avoid grinding into them and leaving a divot showing. :mad:

Hey James,

I plan on making them to the same design as my current corby's. I could shorten the hole and threads in the female end of the corby but then the male side would not fully bottom out changing the grip range. If I shorten the hole up on the female side and shorten the male side the over all possible grip range would get shorter then people that need it longer would be screwed(no pun intended) I find it easier to remove material then add it on. What size do you have trouble with breaking threw to the hole?

Travis,
 
The 3/16x1/4" ones. It's only an issue on real thin tangs/handles or if I don't drill the hole in the scale deep enough for the shoulder. I see your point; I'll just work around it. It's definitely not a deal-breaker :)
 
Yes and I also understand were your coming from. It is hard to design something that will work for all custom makers and all designs so some modification is almost a must but if it is something that is consistently happening I have no problem making changes to the design. So I do appreciate the feed back and will make a note of it and see what I can do to keep everybody happy all of the time.:D

Thanks, Travis
 
Travis, I appreciate you taking the time to respond. As I said it's no biggie and modification is part of what makes handmade knives fun. Thanks also for responding to our requests for different materials even though it sounds like a PITA. Options are good to have!

I'm guessing but it seems you've been supplying Tracy; may I say the corby's I've bought from him have been a joy to work with. Keep up the good work :)
