Drill Bit Diameter for Atomic Slim Daddy Skis

post #1 of 14
Thread Starter 
Want to mount a pair of Tyrolia LD10 Railflex I bindings on a new pair of 2006-7 Atomic Slim Daddy skis. It does not indicate on the top or side sheet what drill bit to use. Anyone know if it would be 4.1 or 3.6?

Also, is it safe to assume that the base bevel is 1 degree, side 3?

The safe thing to do in 97% of situations like this is to drill one hole with the 3.6, look for metal shavings, if spotted redrill that one hole with the 4.1

It is a very safe thing for me to assume.

I have been reading and it seems a lot of people mount their own bindings. Is it that hard ?

Simple on a pre-drilled plate, not so simple directly on a ski!

No offence..but it is one of those things that generally..if people ask other than the finer points about it..for the sake of $20 something..they should leave this to pro's on newer or more difficult skis to mount OR ask/learn/practice on some junk skis. Pick up some out of the garbage,Craigslist,Ebay,Goodwill etc. Another member close to you may have old skis.

High satisfaction for doing it yourself!

Having said that. No it is not hard to do..or learn. A drill,the right bits, the right screwdriver,a tap if needed for the screws,and a ruler,tape measure,some sort of marker.

There is all the information you need right at this site to do it. Plus expert advice.

Have fun!

Comprex - Thanks for the suggestion. Makes sense.

As for mounting your own bindings, I have only done Tyrolia Railflex bindings. The mounting plate acts like a jig, making it easy to center on the ski and mark the drill holes. There are a few fine points to be careful about, but it's not hard provided you are comfortable working with basic tools.

As others have said, there is a lot of information here on EpicSki and it's a great place to ask questions. Always best to make your mistakes on cheap, old skis before doing ones you care about.

No ofense taken. I would prorably have a better piece of mind if a pro installed them I have like 6 old pairs to practice on.

And unfortunately for some of us, a "pro" is not readily available. The young kids at my local shop definately wouldn't give me any peace of mind.

I've also only done Railflex plates, pretty easy if you are comfortable with a drill, a ruler, and have the right drill bit.

I know what your saying. I really don't trust anyone either. Thats why I do most of the work on my truck. I think I am going to do some practice on my older skis. If all works out then I can save some coin on the future mountings. I am pretty good with my hands so I just have to get the feel and all should be good. Thats until I take my first run and rip my rear off :

A few tidbits of info./help/

It is not hard. You can learn to do it and then mount up a nice pair!

if you practice on an old pair or two..and ask about here for any help.. if you need it..you are good to go bro!

If you know how to do it AND a pro messes it up..you simply will not believe how you can "melt down" over that.

If you mount/drill enough skis..sooner or later..you're gonna drill right through one. 'Bout the only way you can prevent it is with a drill bit stop. Or special bits. Without one what can happen..and there is NO real way of preventing it other than a drill bit stop..is that you are drilling away ever so carefully...and crap in the ski grabs the bit and pulls it through. Oops. "Those who have mounted enough skis have either done it or are lying". Not my words. Not such a big deal anyway.
You don't have to have a jig.(You can make them easy enough) There are practically NO super narrrow top sheet skis or race plates left anyways that are so narrow you pretty much have to have a jig.
If you hit metal..it is best to tap them. Some thin/softer metal.. if you have access to a set of machinist bits you can sometimes squeak by with a larger hole and no tap. I didn't say that.
Some metal in skis is so ridiculouslly hard..thick. That a super hard coated bit is not the way to go. Go with a plain very high quality steel bit that is very aggressive. Consider them throw aways. I like Makita's for that kind of stuff.

Practice a bit..Mount up a real nice pair of skis.
You'll feel pretty good!

You aren't suggesting using a standard drill bit to drill your skis are you?: Skis are generally marked for the correct size & "Depth" bit to use. You can't drill through the ski using one. Like these (Scroll down to binding drill bits)

Sure..like I said..the proper ski binding screw bit is best. Thanks! for linking it. I did drill through one ski though. Crap in the core grabbed the bit. My ski.Beat up ski. Easy fix. About 10 years ago.
However..I have mounted/still do...oh..drill..30 pairs/more per winter.. skis,plates..as well as the plates I make, repairs/strips/tear outs,wrecked skis,re-doing bad mounts etc.etc That's about right..I do my ski stuff Saturdays during the season..I drill/mount 2 pair or more..every Sat..4 Sat's per month/4 month ski season.
For..the last 10 years. Prior to that..about 10 pair per winter..for the previous..oh..35 years.
I have NEVER had a tear out..even on a re-mount/repair/custom plate. On mine or anyone elses skis.

Yes..I do have..somewhere?? haha..some of those special bits..as well as some stops,a drill press,jigs, etc..but to be honest..I simply cannot remember when I last used one of those bits..or a stop???..certainlly not within the last 10 years.

Yes..I personally just use standard bits..albeit..I have a wide range..machinists..hard coated ones etc Into my hand drill they go

You're right..for the average person..get the right bit. Or if you are banging them out fast. I don't have to do enough that fast..I can take my time..

Stops are a good idea to be better safe than sorry. A drill press with a stop gauge works also.

We also carry screws to go with our drill bits & taps.

I have been reading lots about doing it but doing it is another story. I have some new Line Blends and a set of Look PX12 that have been staring me in the face since the end of the season. I don't think I trust myself enough yet to attempt them. I am still trying to figure out where to mount the bindings. They will be an everyday ski so I have to take that into consideration. I am by no means a park skier but had tons of fun in the park last season.
