 Poster: A snowHead

I have just purchased a pair of Whitedot Preachers with a VIST 412 binding from a fellow snowhead ..... thanks.
Can someone tell me the maximum acceptable clearance between the skiboot heel and the binding heel piece. Or alternatively the distance of heel piece movement backwards when the boot is locked in.
I have wound the adjuster right in and whilst the boot seems to fits OK, I am worried it may be a little loose when I ski on it.
I currently have about 8mm of clearance with the boot resting in the heel cup and about 4mm of heel piece movement when locked in.
Any views ?

I'm sure spyderjon will answer your question properly but your referenece to an adjuster screw sounds like the forward pressure adjustment. You need both the binding to be mounted at the right length and the forward pressure set correctly for the binding to function properly. Slop is bad - no point having a performance ski and binding then bodging the fit.

Well, the person's real but it's just a made up name, see?

The adjustment screw should stand proud of the binding when the binding is "open"
when the boot is locked into place, the adjustment screw should be flush with the binding.

OK that sounds clear - I will check the flushness tonight !
I take fatbobs point - but the skis have been redrilled once and I would prefer not to do so again if I don't need to.
The adjuster screw I refer to moves the whole heel piece back and forwards - to accomodate different size boots - I guess that the forward pressure adjustment is a separate apparatus within the heel piece. If you set the adjustment right to get the screw flush, then the pressure will be correct.
The problem I have is that I would ideally have the heel piece a couple of mm further forward but can't because it is on the stops.
If the screw is still proud by say 2 or 3 mm with the boot locked in place ..... is that OK ....... not ideal I know ........ but worth redrilling ???

You'll need to Register first of course.

if the screw is still proud when the binding is closed, your heel piece is too tight and you need to move it back 2 or 3 mm - I think. Don't have my bindings in front of me to verify though

Yep, if the screw is proud (of the end of the hole in the back of the binding that it goes into) then the binding is too tight and you will not necessarily release at your DIN setting. If the screw is recessed into the hole your binding is too loose and you can get pre release. Be careful using the screw adjuster at the limits of its travel as a mate stripped one of mine trying to adjust a 325 mounted set up down to his 317 boot sole, the Vist jig goes 320-330 so he was trying to operate just outside its intended limit of adjustment.
Now I've actually written this I'm doubting myself, and it could be the other way round

PBJ, actually rereading your post above it sounds like nbt & I might be getting it back to front (or maybe when you check tonight the screw will be recessed) and you trying to get a smaller boot into a bigger set up (like we were this last season) if thats the case then the problem you would experience is the pre release, if you don't seem to be suffering then...............................
Careful not to strip it, and think on about the fact that you'll be moving the centre point of your boot forward of the intended mark on the ski by pushing the boot forward.

Hi midgetbiker, I think you are right. It actually works the other way round - the screw starts off proud of the housing by about 5mm and I think when the boot fits correctly ends up flush. With my boot, the screw is still proud by about 3mm - there is definitely some forward pressure on the boot as I can see the heel piece move back a few mm when the boot locks in. Question is will it be enough to prevent a prerelease.
Not too worried about the centre issue - the redrilling done on the skis so far has only moved the heel piece back so the boot could do with coming forward a little anyway.
I guess I will take it out next season and see how it goes.
Was considering new boots next season anyway - as mine are a bit of a tight racy fit and despite lots of work are still not that comfortable. I think a pair of new Garmonts will probably come out a little longer than my current boots ..... but its an expensive way to solve the problem !!

Thanks Jon - was hoping you would give the expert view.
Do I need to be concerned about having the heel piece remounted again - 3 sets of holes in the skis ?
How much do you charge for the job ?

PBJ, Any chance the previous mounting holes might suit your BSL?
|
|
|
|
|

They might - I am told they were originally drilled for 314mm sole and have been filled. Not sure how much adjustment there is - my current BSL is 326mm ..... the existing mounting is for 340mm.
I think spyderjon did the mountings ....... so will await his comment !
Am thinking more about new touring boots ..... so might wait until get those sorted before I make an unnecessary change.

You know it makes sense.

PBJ, when I looked at a pair of Garmonts in a comparable size to my Nordicas they were 18mm shorter in bsl.
Pretty sure the Vist jig is in 10mm increments, so it will be set 330-340 at the mo and hence your 326 leaving the screw about 3mm proud, that means the origonal set up will have been 310-320 so still no good for your 326

The lad who borrowed the HSFR from me last season was running the screw 3or4mm out, as I didn't want them redrilling for a loaner. He did report the odd pre release but could also land drops hard enough to start delaminating the front of the skis without stepping out, good job he bought them in the end (not sure they weren't the pair that spyderjon just about ripped the bottoms off at EOSB'08, so maybe just a 'weak' pair  ).
PBJ, it's got to be your choice, the yarn above is true, but so definately is spyderjon's assertion that you will get some pre release as your outside the working range.

PBJ, I mounted these skis previously & the Vist jig is infinately adjustable so it can be set to the exact BSL. A third set of holes will be ok & they'll fit nicely between the existing 314mm & 340mm mounts. A remount is £25.
