How to measure BSL on mounted binding

[wooley12]

Probably a dumb question (there are no dumb questions). Looking at a good deal on skis mounted with Griffon's. How do I measure to figure what BSL they were mounted for? What +/- would work?

[skimaxpower]

There are a variety of ways to figure this out. All of these methods assume that you are using a flat (non-system) binding.

1) Use a metric tape measure to measure the distance from the contact point on the binding toe piece (under the front of the binding) to the contact point on the heel piece (with the binding closed.) This will tell you approximately what BSL the binding is currently set for.

2) Crank the forward pressure adjustment forward as much as you can. Repeat step #1 This will tell you approximately the smallest BSL that will fit.

3) Crank the forward pressure adjustment back as much as you can. Repeat step #1 This will tell you approximately the largest BSL that will fit.

4) Most accurate, most work: remove the binding and align the screw holes with the appropriate minding mount jig. The jig should have a metric BSL indicator. This will tell you the exact BSL that the holes were drilled for.

Thankyouverymuch! That makes sense. I am of the school of "close enough" for binding mounts. Don't really sweat the .05 mm stuff. Maybe if I was a better skier......

They're your knees. Good luck.

I'm sure you are right, but .05mm? Learned alpine to ski on "non releasable" cable bindings and though I ski 40 times a year, the last time I fell was before you were born (I'm a woosie). But you did not know that. PM with your shop and I'll stop by, say hi and buy something. I really do appreciate your answer.

If your your boots fall between the two extremes of the binding adjustment range, you can safely and perfectly adjust them. I think Wooley12 means that he does not care exactly where on the ski he is mounted.

.05 mm is not going to make any substantive difference as to the binding's ability to release properly. That's .002 inches - basically nothing.

[farmer]

no, its 0.05 mm. y'all need to catch up with this metric stuff

[bfree]

Even 1-2 mm doesn't make a difference. I know we all like our wormscrews, but think of the tab adjust bindings that only adjust in ~2+ mm increments.

4) Most accurate, most work: remove the binding and align the screw holes with the appropriate minding mount jig. The jig should have a metric BSL indicator. This will tell you the exact BSL that the holes were drilled for.

Or just measure center/center on the binding screws without removing the bindings from the ski?

As others have said: If you´re in the ballpark, you´re golden.

I started a thread here a few years ago, asking folks to measure up their other bindings or mounting jigs to develop such a guide. No one really wanted to help.

SALOMON = PLUS 55mm

(meaning if you measure from the rearmost front binding mounting screw to the frontmost rear binding screw (not counting the 5th worm gear screw on a 916) and add 55mm, you have the BSL they were mounted for.)

I, like you, thought this would be helpful as a quick check of a used ski before purchasing.
Salomon is the only one I remember.

Hi thanks skimaxpowerfor sharing a ways to measure BSL on mounted binding

That's a good idea.

FKS 155 = 91 mm

PX 12/14 = 36 mm

Measured from screw center.

bsb is supposed to = bsl

BUT since for some people apl = bsl, the term bsb was "created" and now the lengths are 2 different growth goals...and that just doesn't make sense to me...if you're bsb you are bsl because technically THAT'S where your bra strap is supposed to sit - BELOW YOUR SHOULDER BLADE.

anyway. i use bsl as my growth goal label and bsb as my measurment...

Gee, I'm a second generation bra salesman and never heard of bsl used in the biz. What is the "L" mean in brassiere speak?

[wooley12]

Back to ski's. Could the correct answer to "what BSL" be obtained by measuring the distance between correlating front and rear screws on a mounted ski and then setting up a paper jug to the same distance, thereby giving the BSL?

Sounds reasonable to me.
