True center?

Is it more accurate to measure center by going from the tip and holding the tape along the topsheet to the middle and then from the tail along the topsheet to the middle

Or

From the tip straight across in a sort of triangle to the middle and then from the tail in a triangle straight across to the same spot in the middle not accounting for the shape of the skis topsheet

Is it different for symetrical and non symetrical skis?

Does it make any difference at all?

Only answers from people who actually know what they're talking about please

 
Main difference between mounting for symmetrical and unsymmetrical.. Unsymmetrical you would not want to go true center rather core center.

For symmetrical you can normally find true center by balancing the ski. It's not mm perfect but you normally get pretty close just hold a screwdriver up and balance the ski on the end until you find it balances perfect. mark the spot with a marker then measure it from the tail to get the same length on your other ski.
 
Many unsymetrical skis can still be mounted true center... If you are skiing park you want true center no matter what!! If you have skis that really dont work for true center u need to step back, rethink your life, and then go buy a pair that can be mounted true center
 
Hears what I do to measure true center:

Place your skis on a flat surface (floor or table) with the tips pushed up against a solid surface (wall), then measure the full length of the ski (it doesn't matter if you include the curve of the tip/tail as long as you're consistent with both skis and both measurements. Then take whatever number you have and divide it by 2. Keep the tape measure in the same place on the ski and use a small t-square (if you have one, if not a ruler can work you just have to try and get it perfectly vertical) and have the "top" of the T going forward and backwards on the ski (so length wise, not width wise) and put one of the edges at your halfway point (the measurement of the ski divided by 2), that is your mid-point. Put a piece of masking tape in roughly that spot (you can do this earlier too), then remeasure and mark the masking tape with dot, then make the dot a line. Repeat for ski number 2. Then to check your results if you flip one ski around (so tail up against the wall now) the lines should be in roughly the same spot (so they should connect).
 
when I measure out the full length of my skis holding the tape measure straight across from tip to tail it is about 175cm but when I measure from the tip to centre and then tail to centre I get 88 and 88 which added together is 176? is the measurement of tip to centre and tail to centre added suss posed to be slightly larger than the actual ski?
 
It shouldn't, the laws of math and physics don't really allow that...it's probably cause when you measure to the center the tape isn't staying level adding another cm, that's why I keep the tape going from tip to tail while measure, so it stays level. But it sounds like you already have a mark you're going off, in which case you should be fine because as long as you're doing the exact same thing on either side, if they're equal you're at center.
 
am I supposed to bring the tape down to the ski when I check for centre? as in diagonally from the tip going down to the middle and vice versa for the tail?

something like this

I don't, in fact I don't even move the tape once I've measured the full length of the ski, that leaves more room for error.
 
But that isn't how most people do it is it? Like the normal method of measuring center is the way I did it correct?
 
No the way he means is much more logical,

Take the tape.. measure full length of ski

divide by 2... make a mark.. then measure full length on the other... mark in same spot... then measure mark to tail on both to make sure they are both in same spot..

No messing around with the position of the tape then.
 
It's a more logical method sure but seems less practical

most shop techs measure by bringing the tape down to center diagonally making a kind of triangle I believe
 
Not the ones I know and trust to mount my skis...

And if you know this, why are you asking the question...it seems like you just want to do it your way, if so do it that way and don't bother asking the question...I'm really just confused now.
 
- Measuring straight across tip to tip, or whats commonly referred to as true center. (Yes, since the tips are raised, you do sorta make the tape into a slight triangle when you measure down to the near center of the ski, but your mark will be a fraction of a mm off at most)
