New Blade Questions.

[wpotere]

Hey all,

I just bought a new Uhlmann FIE BF blade. I got it pre-wired for ease of install. Here is my dilema...

I have never owned an FIE blade. So, when I went to put the nut on, I noticed that it was loose. What I mean by this is that there is a play between the threads and the nut causing it to pop and then loosen when you try to tighten it. Is there a standard thread size on the tang? If so, what is it? If not, do I have the wrong nuts? (funny how that sounds...)

Any help is appreciated. To me, it sounds like I will be needing to get a replacement. Glad I bought it from a trust worthy vendor.

You may have a personal problem i.e. the wrong nuts!

No...really! The threads on the blade are probably 6mm...you may be using an American Standard nut (12x24 I think), and it won't tighten.

It has nothing to do with the blade being an FIE...that has to do with the metal content of the blade, not the thread size.

See if one of your sallemates has a metric pommel (either inside hex or outside hex, depending on how short they cut the tang) and see if that tightens down.

it could also be that you have the right sized nuts (and all us guys know how important THOSE are ), but the one you;re using is stripped.

Either way...sounds like you need new nuts!!

(man....those were just TOO easy!!)

yeah, some stuff is threaded differently, just ask the vendor what kind of nut you need, and get one. It's like 2 bucks or something. . . Better yet, ask your coach. Coaches usually have nuts hanging ou. . . I mean around!

And somehow I feel I will never be clean again...

Thanks for all the nutty replies!

Couldn't resist.

Actually, I have 6mm nuts that I am using from my old broken blade and they aren't stripped (yet). When I looked on the site The Fencing Post, the only option was inside or outside nuts. Both were 6mm, but that is not the thread size but rather the hex size. So, maybe the inside and outside are threaded differnetly?

Anyway, I have a call in to the vendor to see what I need. Thanks for the quick replies and if anyone else has a clue I would appreciate the help.

I've found that just because a nut doesn't look like the threading is worn, it doesn't mean that it's not worn. I get a lot of use out of my 6 mm x 1 tap-- whenever a nut seems to not want to go on just right, I'll use the tap to "freshen-up" the threading and it'll fix things.

One other thing to consider is that, if the threading on the tangs of your old blades was cut with worn dies (which happens most frequently with Russian & Ukranian blades), that can deform the threading of the nut when you tighten it down so that it'll fit snug with that blade, but not on a blade that was threaded with a good die.

So, are the tang and nut threading 6mm? Cause I am willing to hit Home Depot tomorrow.

Unfortunatly not a Home Despot item: a standard 6 x1 metric nut will not fit into the bore of your grip. There was a thread a while back on this: Mergs stands by the use of 12x24 tpi electrical standoffs (possibly a Home Despot item ) on a 6x1mm tang.

I think the size I use on the 6,, nuts I sell and use if a 5/15th coupling nut redrilled as a 6mm.

[wpotere]

Actually what I was trying to say was...

What size metric tap do you use?

What size metric die do you use?

I have wanted to add these tools to my kit as I really have no local armorer around, so this information will truly help. My preference is Uhlmann, so it will be metric from here on out. Thanks for the information everyone, it really has helped.

6mm x 1 is correct size for tang / pommel die / tap

[wpotere]

Thanks, heading to the store now.

Well, it seems that whoever cut and re-threaded this blade either used an extreamly dull die or the wrong size. At this point, it looks like I am going to have to send it back as this just won't work. Even the die, when threaded on the blade, was loose. Thanks for eveyones help.

Apparently your nuts are broken and you need some new ones, or your blade isnt properly connected to your nuts, and therefore, is not funtioning.

If for some reason you can't return it and get stuck, I can repair it for you - though there'd be shipping to Philadephia

[wpotere]

Thanks for the offer. I'm sure that they will swap it out since they were the ones that cut the tang and threaded it. They may be able to repair the old blade and sell it for a price cut.

You never know what you're going to get!! Take it to a hardware store and find out what works. Look at it under magnification. Fit something to it or get someone to make it for you. A 6mm die is cheap, even at Sears, dress those threads....

The problem is that I did purchase a 6mm die and when I ran in on the threads, it was even loose. I called the company and I have to send it back so that they can look at it and replace it.

You misunderstand. The standoffs are not 12-24, which is about a .216" (almost 7/32") major diameter vice about a .238" major diameter for the 6mm thread, they are 10-24 internal threads or about 3/16". But because they are aluminum or pot-metal, they can be threaded without any preparation fairly easily. Or as I've said before, you can drill it out with a 5mm drill bit which will probably result in a hole .2006" in diameter or a #9 drill, which is nominally .196", but wil probably give a hole around .1998". Either drill size will give you hole that will result about 70 - 71% of the thread you are looking for.

And yes, you can get them at Home DeSpot (nice play, Artisan!)
