Fin Settings Obrien Endo 68

[chyna1966]

would anyone have the stock fin settings for a Obrien endo 68 inch 2013 model? Cheers andy

[jayski]

Try 2.511 depth

6.732 length w/jaws

.7205 DFT

9 deg wing

29.5 bindings

@jayski

are you sure those are right for the 68? kind of wacky settings

[Horton]

wait.... jaws? really?

[jayski]

@Horton, what's 'wacky' about them? and yes jaws, Mr.Ross provides measurements with jaws...

[SkiJay]

@jayski I'm sure you know, but for the uninitiated, jaw measurements only work for number sharing if both people have the exact same make and model of calipers.

[DanE]

Even with the same make and model jaw measurements cannot be shared, why?-

the surface used when making jaw measurements were never intended to be used for measuring purposes, therefore the manufacturer of the caliper never precision machines that area of the caliper.

There seems to be a misconception that if you buy an expensive caliper it would work but since the jaw area is not for measurement, it won´t.

Now, the later versions of slot calipers are ment to resolve that by actually have that area of the caliper precision machined but several posters on here claims even these calipers differs grossly on jaw measurements due to different dimensions of overall shape of caliper head.

Want to share LOF? tip measurement is the only way unless you want to ship your own caliper along with the numbers.

[jayski]

@SkiJay well the two of us have different calipers and get the same #'s with them...you know his old dial caliper and mine is a Mitutoyo digital...not like tips is accurate either, that has a variance based on the operators...I get that the perception is tips is best, just like everyone gets the same DFT tail measurement...

[A_B]

Tips is best when laying the caliper on the ski bottom and making sure it is not further past the tip on either end of the fin. I agree about the jaws variance though. Have seen .011 difference between two calipers that I owned.

I like the numbers posted by @jayski, but the length can be tips of 6.845... also, 68 can bump forward a bit, especially depending on binding location.

[Horton]

well it makes sense when @Drew says it

 

Sorry I to not speak "jaws"

 

[jayski]

...goes along with your grammer

[jwr]

Well how about for a 67?

[jayski]

@jwr sent u a PM

[jwr]

@scotchipman Drew Ross gave me

28.75

6.845

.715

2.510

9 degrees

[rfa]

trying out a 65.5 Endo...O'Brien website has the following #'s:L=6.725; D=2.505; DFT=0.720; Boots 28.75'...would anyone confirm if these are correct? I cannot even get to the L=6.730 (using tips) unless I modify the fin...it bumps up against the holding screws. Any suggestions or different numbers? Thank you

[Horton]

68 settings 30" 6.940, 2.450, .760

 

 

[Chef23]

@rfa where did you get an Endo.

[Horton]

@rfa‌ those numbers seem wrong

[jayski]

@rfa length is with jaws and DFT try .715

 

@Horton Drew give you those #'s?

[rfa]

Thank you @Horton! This is helpful as it shows a significant change from the factory #s. Anyone with 65.6 #s?

@chef23 a friend of mine letting me try one.

[Horton]

@jayski‌ those are Yoda numbers. He is very strong with the force. Those settings are money.

[Horton]

@rfa‌ need to find old elite settings for reference

[rfa]

Thanks again @Horton...the Elite #'s on the O'Brien site are exactly the same as the Endo's...not much help there.

[Horton]

I have good settings some where. Gimmie 24 hrs

[rfa]

Thank you so much! take your time... when it's convenient for you is good enough

[rfa]

@jayski sorry i missed your post with your advice...thank you! I changed the L today to 6.850 (tips) and it made a definite difference for the better

[Horton]

@rfa try 29 / 6.840 /2.495 / .765

 

 

[rfa]

@Horton ...I am pretty close except for the DFT where i was at 0.720...will try your #. Thanks again!
