This is the World Famous TelemarkTalk / TelemarkTips / Telemark Francais Forum, by far the most dynamic telemark and backcountry skiing discussion board on the world wide web since 1998. East, West, North, South, Canada, US or Europe, Backcountry or not.

Here is the original:The earlier posters are correct--the skis are symmetrical and the bindings are asymmetrical (the wider side goes to the outsides of the skis).
How to mount 3-pin bindings:
Tools: #3 Posidrive (or Pozidriv) screwdriver (not Phillips), drill, centerpunch (or sharp nail),
9/64 inch drill bit, 4-hour (or longer) epoxy

BTW, the BD Binding Buddy has a posidrive bit

0. If you remove old bindings, there are small plastic plugs that you can put in the old holes. However you do it, plug and epoxy the old holes to keep water out of the ski core.
1. Put 2 inch masking tape on the mounting zone of the ski.
(To draw lines on.)
2. Draw ski centerline on tape.
3. To find (lengthwise) center of ski. I balance the ski over a
sharp edge="balance line". Other definitions of center: halfway
between tip and tail, halfway between ground contact points. (All
should yield similar results.) The balance line is probably best for
XC skis.
4. Average balance line from both skis and draw on tape.
5. Locate hole #1 on centerline 1 inch forward of balance line. (This
puts the pins on the balance line.)
6. Center-punch and drill hole #1 with 9/64 inch (3.6mm) bit.
Use tape on drill bit to limit depth. (It is best not to drill holes
through the base.. It can be fixed if you do...)
7. Dry mount (no glue) the binding with #1 screw only.
8. Put boot in binding. (Note left and right bindings and boots are
different. The skis are symmetrical.)
9. Center heel on ski. (I put a bit of tape on the back of the
heel, lay a straight edge from the center pin hole across the
center of the heel, and mark where the straight edge crosses the
back of the heel. When centering the heel on the ski, I simply
align this mark with the ski centerline.)
10. Remove boot without rotating binding.
11. Trace holes #2 and #3 from holes in binding.
12. Remove binding and drill holes #2 and #3.
13. Dry mount binding with all 3 screws.
14. Dry mount heel plate under center of boot heel with 1 screw. (#4)
(Don't install the plastic snap-in plate until final mount.)
15. Do other ski up to this point.
16. Remove bindings and heel plates. (Keep left bindings with left ski,
etc. The holes may not be symmetric.)
17. Mix epoxy and put in holes.
18. Mount bindings and wait for glue to harden. (I wait til the next day.)

Notes:
* In case you need to remove the bindings, 4-hour epoxy can be
softened by heat, faster epoxy cannot.
* It is worth reading http://www.telemarktips.com/BindingMount.html This describes how to mount similar Telemark bindings rather than XC ski bindings, but some of the tips are useful.

what are the skis? is this more XC, or ski area, etc?fisheater wrote:Skis are on the way, picking up some 3-pin cable bindings. I know how to find chord center and balance point, do the pins go on the balance point, or chord center? I have mounted quite a few alpine bindings, making my own paper templates, but there was always a line on the ski and a line on the boot. I am new to mounting pins, and would appreciate some help.
Thank you
