Vulcan blade retaining tension

[walkin_mark]

Hi,

I've got several SOG knives. My experience with the SEI taught me as much as I know about torquing the screws in the handle around the pivot and arc-lock to get the knife to stay in the handle and not "shake out".

The blade on my new Vulcan is quite a bit heavier. It is breathtaking the way it sweeps from the thickness of the spine to the extended hollow grind, but even with all that weight removed, it is heavy for a SOG clip-on folder. It has more of a mind of its own about overcoming the arc-lock's retaining force. The blade is too easy to shake out of the handle for my taste, even sitting at the bench making microadjustments. Also there is one less screw to fool around with than on the SEI.

Is there a proper sequence of tightening, a thicker stickier lube, or some way of keeping the beautiful (you can't tell anything from the pictures - this thing is go to the moon slick and hypnotizingly interesting in its geometry - a knife nut's dream) blade tighter between the scales and still fairly easy to open and close?

Somebody wise me up. I'm certain that I'm doing something wrong.

...I wish I were able to shed some light on your query walkin_mark but I'm so new to SOG knives that I'm still walkin' around with my umbilical. I will say this about the Vulcan. When I recieved mine it too exhibited the condition you're speaking of...I tightened the pivot screw so little that it amounted to putting the T-wrench in it and "thinking" that I moved it slightly...it was that little an amount of movement to the screw. It was all it needed to keep it in the frame securely yet retaining the super slick deployment...Mine actually has a nice firm snap to it when it enters the frame. I know I've been of little help here but it's what I have experienced with the vulcan. I'm very sure I'll be asking for a lot of advice myself when it comes time to take apart my SOGs in the future...I see all kinds of fun when I have to replace springs and such in my Flash II's...LOL...

DarrylS,

Did you notice how even though I quietly made this post on the back page devoted to SOG, instead of airing it in a general forum, I received no responses from anyone at SOG. Do you think that no one in the company monitors this site daily? Hint: There may be no answer to my question.

They have a finger chopper problem here that is way over on the real side of marginal and by responding to a post like mine is to admit that the thing is less than perfect in case they end up in court some day. What do you expect! I wouldn't want to own a knife company looking for growth that was trying to market a good quality, but a litttle pricey, line of knives to what is left of the so called middle class. Loans come due and that is probably the reason the thing is out there on the market without some kind of tension change in the arc-lock.

I adjusted it as best I could, then sprayed the hell out of the action with Ballistol and left it overnight for the tight tolerance points to develop some vacuum surface tension and the Ballistol to lose some of its fluidity. It is better, but it would still be not considered safe by many a bold but sensible person - I mean there are a hell of a lot of good knives out there that would make a blade freak happy - why take a chance with a finger tendon with this one. Also, anything like this is typically going have to be monitored and adjusted. I hope not too often.

It sure is pretty though.

I could probably never go to court with a useless digit succcessfiully now after revealling (legally the term is publishing, I think) my understanding of the product. the defense counsel would ask: "If you knew it was a bad design, why did you put it in your pocket and reach around for it in the dark?" We laugh at people that stay in the scary house in a slasher flick!

My favorite quote is by that great Missouri boy:

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." - Robert A. Heinlein

















































I tensioned it sprayed the heck out of the action with Ballistol

There is no cover up here and sometimes I do not check or respond to posts everyday. I do not monitor this site daily and when I do it is usually only once a day. I resent the fact that you are insinuating that SOG has a problem with the knife and are purposely not discussing it in order to cover it up. Completely untrue!

Your comments were the first I have heard about anything like this with the Vulcan or any of our other knives. I have not responded yet because I do not have a good answer for you on how to adjust the tension on the Vulcan. I am talking with engineering about this and am trying to find an answer for you.
