Removing pins that arent broken?

[Rylorien]

Ok well, after having read most of the excellent sites of members here I have found oodles of info on what and how to use to repin bali's but yet to find anything on how to remove the existing ones to replace them with better pins. Any Ideas?

Oh man, I just went through this tonight. It's a bitch!

First I tried drilling them out. Not good. Drill slips a couple o' times and scars the handle. Well, half an hour and a 1/16" drill bit later (that's right I broke it, have a laugh) I decided to use the traditional approach. I taped the handle around the pin and started filing. Ten, fifteen minutes later I finally got the head off of the pin.

It's then that I realised the reason that this pin wasn't loosening like the first: It's bent. So I use my broken drill bit and a small hammer and tap, tap, tap, ah! It's out.

So, finally ready to re-pin. But, I've decided not to go with 6d finishing nails. Instead I'm gonna try to use a 1/8" Sex Bolt. Until I find one though, I've got nothing to flip. I think I'll probably buy another Jag for now.

I hope my rambling has helped in some way.

That is hard for me to imagine, sense I have hundreds of butterfly knives laying all over the place. I kinda like the bigger 6" Taiwan, that opens up to 11". It's differnt than all the rest of them, and more fun. Also it makes a neat clang' sound when you close it. Thanks, JohnR7 www.balisongknife.com

Good luck on finding a 1/8th inch sex bolt.

When I started making my balisong knives I went looking for a supplier for the small parts, basically I was going to use screws similar to the BM blade screws.

No Luck at all. A company in Ill. was willing to make some for me, but they would have cost me 0.98 cents each.

Doesn't seem like much, but I would have had to buy 1,000 at a time to get that price.

You do the math. So I made my own.

Most sex bolts that you will find are a min. of about 3/16 to 1/4 in size and made or either brass or aluminum. Never did find any made from any series stainless.

Even went to a company that supplies aircraft parts, again the same thing no luck.

I do wish you well though on your search.

BTW, the holes in the Jaguar have to be drilled out to 1/8 or larger. Use a solid carbide drill at about 1600 rpm with plenty of coolant and the blade clamped very tightly

USE A DRILL PRESS, DON'T TRY IT BY HAND

You can use 1/8th stainless welding rod and very very carefully peen the end over into heads which works well. Just don't get too carried away as the jag handles won't take much abuse.

As for removing the pins, try a cutoff wheel on a Dremal tool and very carefully grind the top off.

Best of Luck

Yeah, like Chuck G said, just take a dremel cutoff wheel and let at the head. Those cutoff wheels should cut through like butter in about 2 seconds.

Although it might be interesting to put stronger pins in, I think provided the trouble and time it takes, you'll be better off buying a better bali.

That would be expensive for one person to do, but why not somebody who sells Jags constantly? If you follow me. I seem to remember our gracious host, Mr. Turber, saying that he was looking for better pins...(hint, hint)

But seroiusly, if a large seller did this, I for one would pay an extra $5 or so to have better pins.

I can make your pins, but they won't be 1/8th inch. way too small for my tastes.

I can make a set of pins that will work with your Jag, have done it myself many times for my own.

What I do is drill out the handles after removing the blade to 3/16th of an inch, and then drill the blade out to match.

Regular drills will work on the handles, but you have to use carbide drills to drill the blade.

Required items to do the job, Drill press, drill press vise, spindle speed of about 1600 rpm, slow and light feed presure and plenty of coolant.

Pins are made of 416 series stainless with 6-32 socket head screws.

By using screws you can adjust the tightness of the handles.

I have been thinking about setting up a kit to do the job. What do you think?

Two complete sets of pins and a carbide drill for about $30.00.
That way you would have a set of replacements pins or you could do two knives.

Feed back welcome.

Regards to All

Actually, that's an interesting proposition. I may already have the 3/16" carbide bit though. I'll have to check. Get back to you...
