AHHHH!!!!! Problem after de-assisting my 586!

Yeah go for it, what are the chances a knife company would look at a knife forum and look at a thread on their knife. and read the thread, I mean really !
 
And Edgesnarf, thanks for the tip. I think that's what happened because there's no other reason why the scales would have had so much space between them. So that explains the original problem with pivot tightness, but I'm certain the tight axis lock was from the liners themselves being too spread apart. It would have had to have something to do with the spring in the pivot, because when that was gone it solved the problem.
But as of right now, the knife works great other that the fact that it doesn't lock. Until I figure out what I'm gonna do about the springs, I'm kinda just going to wait. Maybe BM will miraculously change their policy on sending out springs one day.....:rolleyes:

Don't wait for BM, order some .025 music wire spring stock from McMaster Carr and make all the omega springs you will ever need. Start by forming wire around a mandrel of approx omega spring dia on the small side and then form the ends. Easy stuff!
 
Hey, does anyone know how long the omega springs are supposed to be when straightened out? Just to give me an idea of how long of a piece I should cut from the wire. I bought the wire in straight 1 foot sections
 
I've only sweated the possibility of not getting one folder back together on one knife, and it was my 943 (holy crap that one was hard). The Barrage is easy, but you just have to be patient and ensure that everything comes out in a way that allows for you to ensure it goes back in same place in the same way (mark a sheet of paper and set each screw in a place - if you're worried about parts rolling off, get an old egg carton).

I've taken a lot of different folders apart and put them back together. The key is preparation and patience (and never panic - if things start to go wrong, walk away and think about it for a bit before coming back to work on it).

Good luck next time, but Benchmade will take care of you this time.
 
Just start with a long enough length to form around a .5" dia shaft clamped in a vise and forming a u shape by pulling tension on the ends. Then bend the loop and right angle. The dia of the omega shaped spring needs to fit into the recess machined into the grips. That's the target dia minus wire section dim x 2. The .5" mandrel is my best guess so measure the grip feature and approximate actual omega spring I.D.. Using the longer piece of wire to form the shape then trim the ends
 
Awesome, thanks. I did it and the knife is now a manual folder.:thumbup: Unfortunately there's just something about it that's not quite right. Above all it's the sound, I think. The opening and closing sounds very different and weird. Also worth mentioning that while the diameter of spring stock I used did work, it might be a little stronger than necessary, causing the detent to be very strong and the knife to loose some of its smooth manual openability. But still, at least the knife is no longer assisted and is finally back together. :) It has now become more of a work knife since my 707 has permanently taken over as my edc. I foresee using the 586 when I am going somewhere for a while and need maximum edge retention and ergonomic comfort. Maybe it will become my all time favorite heavy duty box cutter
 
Once took apart an auto axis mini Rukus to see if i can make it a manual action. Big mistake. Was a lot more complicated than i thought and ended up finding out there was no possible way to take the auto feature out without messing it up. Was finally able to put it all back together though. That was a tough one.
 
Increase in spring rate could be wire dia which I think is .025" or the omega formed dia is on the small side. You should try and form the largest dia that would fit in the handle feature for best spring life which would also reduce spring rate.
 
Seems like a lot of hassle for little to no gain.


My 586 is amazing

Krissig12,

If you send your 586 back mostly intact we will take a look at it and try to get it functioning again. We will specify if you want to leave the spring out, leave it out when you send the knife to us with a note. Thank you!
 
Sunyata, I agree. It's good as is, but if you gave me the option of having it back the way it was, I would definitely choose that. Now I know why it comes assisted. It's just not built to a manual folder. With out the spring, locking it open sounds dull and closing it sounds hollow. Maybe with the stock springs still on it, it would have been better. Oh well, still an awesome knife
 
Thank you so much! You guys really are the best:thumbup:
That's what I call going above and beyond
 
The 581 and 586 are real precision pieces and some of my favorite EDC folders of all time. Should have NEVER taken it apart yourself or taken it apart at all. Spending a few bucks to pay someone else who has a good bit of experience de-assisting AO folders especially Barrages (they are indeed out there) would have likely been quite worth it. Taking apart a 581/586 without knowing the methods Benchmade used to screw them together so well and with some impressively tight tolerances is almost like trying to disassemble and reassemble a mechanical watch without ever having done so before and expecting it to work. Expensive mistake there with BMs reinforced pricing nowdays. Send it to Benchmade, yes they will be able to tell you took it apart. 50/50 chance weather they void your warranty or not. Don't be surprised if they wont honor the warranty anymore and you have to pay whatever amount out of pocket to get it put back together correctly they see fit. NO they will not leave out the AO. The knife isn't correctly assembled as designed without it. Why would you want to remove the best most kick ass AO in the industry anyways? Not sure if the 581/586 even have a detent since the coil spring that is the AO is under a LOT of spring tension so much so that the coil spring may negate the need for a detent? Guess I will email BM and ask them.

Do not feel bad if you have to send them the knife in pieces in a Ziploc bag they see that all the time. I believe you will most likely be charged money for reassembly but I am sure it will be a lot less than a new 586.

Good Luck, were all counting on you.
 
FWIW I did pretty much the same thing a couple of years ago w/my mini-Barrage and sent it back to BM with the blade only partially closed (it wouldn't close or fully open) and made terrible noises when attempting either. I called them them and told them I screwed up and they said to send it in and they probably wouldn't charge me anything...and they didn't! Came back good as new and it only cost me postage.

*And in regard to BM customer service in general, about a year ago I complained a little by email (was havin' a bad day) because they sent me the wrong (free) deep carry clip with no screws...and, I'm not making this up...responding, they sent me free: 2 X Blue Lube, 2 X Blue Lube Cleaner, 2 X BM coffee mugs, and 2 X Blue box torx kits...that's around $100 free swag at retail and I wasn't even buying anything?!! Ive been fortunate with every knife manufacturer in that I've always recvd' excellent customer service but BM takes the prize with that act of generosity...I've told many people since then about this incident and am still somewhat in shock that they went so over the top to address my petty bitching. What a magnanimous company!
