Nice work. Very creative.
I’ve just invested in the Dynafit beast 14 for my uphill setup. I’m not as concerned about the weight on the uphill as the pins on the downhill. Is there anyway you could do this with a beast binding?
I’m imagining that you have any toe piece, have it mounted behind the pin insert like he does, (but you can remove it), and then somehow being able to move the heel piece? Or maybe just leaving the heel piece in place and having a second set of risers?
With a standard alpine toepiece the Beast 14 will have undefined release. You might not even be able to stay in that monstrosity. You’re on your own there.Quote:

This is for people who want a low-weight uphill mode but alpine downhill.
Oh simmer down I’m just posing the question.Quote:

Lol... and I'd say he gave you your answer.Quote:

Any update on how these are working for people? Still very intrigued by the idea
This looks fucking brilliant! Would it work with OG Attack demos? Has anyone tried that or know which differences between Attack demo and Attack2 demo might pose challenges?
Gen 1 would work too depending on boots. The benefit of gen 2 is the brake comes off with the heel, and the toe accepts AT boots.
This is tempting. Finding toe pieces might be slightly annoying
The brake arms on the orig attack are attached to the track, not the heel-piece - so it won't really work. [I guess you could wire the arms up for the climb and reverse it on the down - but that's even more fiddly.Quote:

Have you played around with this project yet?Quote:

I am in Austria. But i am super keen on some tech toe slide on adapter plate.
Could wire money if needed.
I'm no expert on 3D printing, but the adapter would have to be pretty stout given the twisting load when sidehilling.Quote:

Or you could grind a notch into the edge of the baseplate somewhere and locate the set screw there, so the adapter can't move forward or back. Drill and tap the top for the tech binding.
Sorry, unfortunately I've put this project on hold, just don't have time for it right now and just sold the three pair of Attack2 bindings I bought for it.Quote:

Timely bump... I was just thinking about this setup this morning. Going to start looking for Attack AT demo bindings. Thanks for the original inspiration.
Not sure where you are located, but there is a pair for sale on Facebook in salt lake. I can send you the link if you want it.Quote:

Definitely not as stout sounding as what you described, but the whole thing took me about an hour to do and I've got 5ish days on them with no slop.
The stack height is up there and they're heavier than all hell, but I'm stoked to have the tech toe piece to unlock a broad quiver for slack use.
Are you using them only for the up & swapping proper toes for the down? If so, what's that transition like in real conditions w/snow/ice crammed into the tracks?Quote:

I didn't have any issues with icing, but I only used them at our closed down ski hill (well traveled skin track), and very short tours from sled bumps. You can slide the toe piece on/off from either direction, so I guess if the track ices up on one end you've got a shot on the other.
For a climbing helper I just use the heel piece. I engage it, slide it all the way forward, and get a good amount of lift out of it. Adjusting them from flat to climb on the fly is a real bitch, but I'm not too worried about it.
I have Tectons on a ski I love for a DD touring rig, so these won't see much use. For me, it's a great option to have as a back up, for guests to borrow, and to throw on some giant powder skis I have with Attack2s.
Pictures? I’ve gathered all the parts to build these frankenbindings and am going to start playing around with assembly soon. Interested in your slide on/off tech toes. ThanksQuote:

Thanks and praises to Lindahl!
Mounted my FrankenCAST setup this afternoon. All went as planned given his directions and some measure twice/cut or drill once protocol. I did wimp out and buy Voile splitboard heel risers instead of manufacturing my own.
gorgeous.Quote:

Here are the heel risers that I used. I cut off the forward adjustment tongue, butted it in place against the cut off demo track, and secured it with a new single screw. It comes with machine screws for inserts which I didn’t use. Spendy, but cheaper than my hourly rate to make some or a trip to the ER with a sliced finger. Easy button.

I got an extra pair of Attack2 demos (NIB) if anyone needs 'em.
Anyone have an idea of the weight of the tracks + heel risers? Curious how this would compare to shift in the touring layout

I'll weigh today & post.Quote:

So if the toe track is cut by 20%, we have 130g toe track + 100g heel track + maybe 90g heel risers, super light tech toe would be about 80g. So around 400g per side for the touring config?
Sounds pretty great to me. What’s the minimum distance between toe pin line in the alpine toe vs the tech toe?
Out of curiosity, how many people would be interested in a slide on plate for the toe track for tech toes? Like Jondrums mentioned. It’s be pretty easy to design in CAD for me, a company called Protolabs can machine them out of aluminum easily. Cost is expensive unless you get many made (probably 7-10+ pairs)

I would definitely be in for a pair.Quote:

I’d be interested.
Did a preliminary CAD for a dynafit toe adapter plate that uses the standard 30x39mm mount pattern. Preliminary weight would be around 50-70g in 7075 Aluminum. submitted a request for quote assuming we can get 10 people to order. I still need to do final CAD work for an accurate weight, don't have a toe track with me right now.
I was also looking around and saw these bindings on Voile. 125g for the toe pieces alone, brakes are another 82g each (prior to cutting anything down). Not bad, and the mounting pattern is extremely small. Cost is good too.
Could be a good candidate for either mounting directly to the ski, or on an adapter plate (weight the plate weight would be cut down to maybe 30g. I know most who would do this mod probably already have toe pieces they'd want to use.
Touring weight I'd get would be:
Toe Track: 115g (I think it can be cut down more)
Heel Track: 100g
Voile Brakes: 75g
Adapter Plate: 60g
= 350g + Toe Piece of Your choice. 80g fro Low Tech Race or Superlite 2.0
430g on the up for the performance on the down would be pretty stellar. Could even get some boot center point adjust ability on both the up and the down too.
The adapter plate may be tricky though, not sure if they'll be able to manufacture it the way I want it designed.
Have you looked at the various plates avail from Tyrolia?
Not sure how that would help. The tricky part is in the way the track "captures" the toe piece/adapter plate.
3D Printing Probably makes a lot more sense.
After shipping, the plates would be around $75/pair in this material: https://www.protolabs.com/media/1019...12-black-f.pdf
I would think plastic should be strong enough for this purpose, there aren't too severe of forces on them skinning up. I would not ski down on them. If they ever break they'd be cheap to replace (cheap enough maybe to have a spare in your pack).
Some other plastics too I was looking at for around $100/pair.
~Ceramic material (not too brittle though) for $125/pair.
There's a metal plated material that's much stronger, waiting to see on the cost for that. Likely more like $150/pair
