Finding telemark boot center without pin holes

[6CA7x4]

Trying to nail down some dimensions to order some B&D shift plates. I see telemark boot center defined as half the distance from the back of the boot to the center hole (for 3-pin bindings). But my boots don't have pin holes and I don't have any 3-pin boots around for reference. If I measure boot back to front of "duckbill", how much should I subtract to account for the pin holes? I can guess it's around 1.5-2.0 centimeters, but really need to nail it down precisely.

Mine measured straight up 9/16" front of duckbill to center of pinhole, which is under 1.5 cm(1.42875 cm to be exact). If your boots don't have a pinline or pinholes I would suspect that your shell already has a centermark molded onto it

Thanks. Crispi XP. Stared at them plenty; no center or pinline mark unless I'm really missing something obvious.

Just mount them so that when you face plant, the tip of your ski hits you just above your eyes. That's how I did it in the 90's.

I usually manage to end up on all fours riding the skis backwards down the hill. It's fun to learn new things.

I thot you would measure boot center on a tele boot front of shell to rear of shell ignoring the parts of the sole that stick out ?

just for yucks I quickly measured my garmont AT boot and the mid sole line on the shell is NOT the mid point of the sole

I'm just going by this:

http://www.newtelemarkguide.com/wiki...rk_Boot_Center

"Boot center, in this case telemark boot center specifically, is the midpoint between end of the heel and the 3-pin line on a telemark ski boot.

It is commonly used to align the skier's foot to a mounting reference point along the longitudinal axis of the ski. In contrast to using the 3-pin line of the boot, the boot center convention abstracts the boot size from the alignment. Boot center reference for a small foot is the same as for a large foot.

NTN boots have a molded boot center mark like an alpine boot. Most 75mm boots do not, and the mark must be measured and marked manually."

I wouldn't think there'd be much difference between "shell midpoint" and telemark midpoint by this definition, and it should be a lot easier to measure accurately. This is not the same thing as sole midpoint, since the "duckbill" will throw everything off.

it used to be so complicated, with ball of foot, center of boot, pin line, etc.

For years most of us mounted further forward, splitting the diff between ball of foot and boot center, figuring that helped pressure the rear ski when the rear heel was lifted.

Lately, everything is just centered like an alpine boot and it still works good.

dont overthink it. Either just split the boot in half, or use the suggested pin line deduction. 1.5 cm to pin line from end of boot seems like a lot, but it could be right. Maybe its only 1cm.
Even if you did 2cm, that just moves you forward a bit more, which aint bad on tele. We all used to move forward.

Another idea is to download a template for your binding. That will show pinline and boot center for your BSL

(overall length - 1.5 cm)/2

Pin line is a standard 14mm from tip of the boot.

^^^correct, pinline is 14mm behind boot toe. Measure entire length including duckbill and subtract 14mm, divide by two.
