Spacer changes on a 707 sequel

Anyone tried to tinker with spacers on 707's? Has anyone successfully taken out the spacer on their benchmade and put in open spacers?
 
I haven't done it with a 707 but I (and lots of other people) have done it with 710s and 705s. It's just a question of finding the right spacer at one of the knife supply companies.
 
Technically "spacers" are unthreaded, "standoffs" are threaded. W/ single-screw attach either will work, two-screw needs threaded.

I've made standoffs for all but one of my BMs that came w/ a nylon backspacer, this a 525M4:

If I had a 707 I'd tell you what the gap is, I don't. If you're lucky there will be comm'l s'offs avail-- o'wise you'll have to make your own.

I have done standoffs on these models too. I believe the 707 is pretty much a 705 with a bigger blade, no?
I have found that the blade hits the standoff that is closest to the center of the knife because of this bigger blade.
It's not the height of the standoff in question here. It's the diameter.
I have even tried 1/8" pivot barrels; with no luck.
Blade hits.
He's looking for a "yea, I've done that and this is what I used"
 
Replaced the black spacer with G10.

(still need to countersink the screws just a bit more)

You'll need to know what the gap/b'spacer thickness is. Once known, check USA Knife Maker Supply, KnifeKits, and McMaster-Carr-- they all sell standoffs. If they're not avail at your exact size buy the next one wider, reduce.

ryxlyx I'm not sure but I don't think you read my post?

It works like this; I'm making some custom scales for his 707.
The customer would also like to have standoffs instead of a backspacer. (Who wouldn't)
So, I told him I would need the knife in order for me to do the standoffs.
Now, instead of having the added hassle of sending the knife out to me.
Which he really doesn't need to do to get the custom scales from me. (I have a 707)
He would prefer to purchase some himself and just put them in.
I too would like to know what that part/standoff is.
Because as far as I can see; a custom fitting is in order here.
Unless we have someone on here who has done this.
You know, just by changing out parts.
Well?...........Anyone?
 
Keyman is on his game. Although I am not a customer of his (technically). I am a supporter of his hobby.... :thumbup:
 
If you're hitting a 1/8" spacer-- less diameter it would seem than the depth of the backspacer-- that would suggest to me a blade dropping further than it's supposed to. I've found the same on some 525s.

I'm on my game too....
 
The blade's not hitting my custom backspacer. Which is slightly wider in diameter than the screw. But, anything bigger than that hits and that's on two totally different 707's.
Which is why I would not want to send a standoff out for installation by the end user. But, would prefer to do the fitting, in hand, myself.
Don't you agree Rick?
Do you have a 707 with standoffs?
I'm not doubting anyones skills here.
I'm just looking for some one who actually has standoffs on their 707.

I didn't mean for my post to give that image. I know you both are on your respective games. That is why I was asking the general public! I was just looking for some ideas/to see if anyone had done it.

This is what I was really trying to get across on my post. My lack of game in in the knife world blurred what I was trying to connote.

SO... is this a custom job? Or has anyone had luck with over the counter parts? Keyman what was the spacing measure you tried (if you wish to share)?
 
Sorry guys, sometimes my hackles are a bit premature-- we're cool....

Keyman if I understand this correctly we've got a blade that DOESN'T hit a custom b'spacer-- but would hit a 1/8" spacer/s'off.

I guess my question would be-- would the blade contact the factory b'spacer? Unfortunately I don't have a 707 to look at. If the blade WOULD contact a factory b'spacer, then it is dropping further than it should. Is it possible you have 2x707s, both of which fall too far? Yes. As I said I've got a couple 525s that do that-- one blade (minus the b'spacer) drops an add'l 3/16" at the tip after closing normally-- it'll likely contact the screws.

Would it be possible to slim the 1/8" sleeve further (sanding), so it won't hit? Problem tho is the visuals-- 1/8" on even a small knife pretty skinny.

I'll check back--
 
Just dawned on me what I'd do-- w/ a blade that WON'T fall so far so as to contact the frame screws, I'd buy/fashion a simple 3/16" THREADED s'off to the right width. Then I'd start flatsanding one side of it (sanding parallel w/ the hole)-- I'd sand till I literally broke thru to the internal threading (the drilled hole). Installed, the HIGHEST point, w/ the sanding faced into the blade edge, is now the threads-- which you're saying doesn't contact the blade. You don't need 360-degree base contact on these things, all you need is something that won't collapse under pressure. Shouldn't show, unless you looked for it between the liners.

A little extra time, but I'll guarantee it'll work.
 
The deeper belly on the 707 could well be an issue. On my 705s I used a .140 standoff. Benchmade says both have the same thickness bladestock, so assuming the washers are the same (which seems safe), that's the thickness you're looking for.
 
It was JNewell's treatise on 705 standoffs 2 years ago on the BM forum that got me interested in these things....

I would still measure tho, for 2 reasons. One, blade thicknesses are not always reported correctly. Warn 583-1 universally reported (every site you look at) as .134" blade thickness (I traced this back to BM last summer, but can't find the knife now on their site), Barrages at .121". Turns out the 583-1 thickness the same .121" as Barrages, which is why you can swap them w/o diff washers.

Secondly, while I also don't own a 705, I recall them being described as thicker than 707s. Quite possibly it's scale thickness diff, but also possible (tho I agree w/ JNewell, unlikely) that the washers are diff.
 
Thanks, ryxlyx & JNewell.
I knew you guys wouldn't leave me hangin'

I too think it has something to do with the bigger belly of the 707. That design change certainly make me suspicious. Especially given the location of the problem.

Nice, I will definitely use this.
Still, I think I would feel a lot more comfortable hand fitting this piece to the knife in question.
Verses making the part and sending it to the end user for installation.
