    I am a newbie on the splitboard.
    But the weight was the first thing I noticed when I set up my board the first time. The current binding interface could definitely need some improvements in that regard.

    Keep up the good work!

    If you are ready to make them I’d be ready to order.

    You know there’s a ton of interest here. Make them available and we will buy. I’m glad someone in our community is getting it done.

    That’s a sweet design.

    I was wondering about the bindings while in the board mode. From what I know of the Voile pucks, there would be a space between your bottom plate and the top of the board. How you thought of putting a peice of UHMW to fill in this gap, or shortening the voile pucks? I think that it would stiffen the binding even more and get rid more of the side to side roll that the Voile design has (and that the old Burton design didn’t have). Wider contact is more responsive right?

    You’re definitely close to having a final production design. Maybe a swiss cheese version to lighten them up even more?

    Sell me a pair!?

    That looks pretty sweet.

    The only thing I’m curious about is that it appears the pin is only held in place by UHMW PE. There is a screw in front of it but does it go all the way through the UHMW PE to the AL? I’m not sure how much abuse that would take in ski mode before the UHMW PE starts to deform and open up or crack. I’m aware this is a proto and as such is more proof of concept than final product so it’s very impressive even at this stage. Do you have any plans for reinforcing that area? Maybe an oil impregnated brass there or some other durable lighter self lubricating fiber reinforced thermoplastic like Vespel or Torlon. Although they may get brittle at low temps.

    Lookin good either way. Keep us posted.

    Looks like a pretty sweet design. Way to go!

    the front of the binding does look like it could binding up in skin mode. The front of the toe mashing up to the ski itself. Couldn’t really tell if this is an issue or not. Definitely an improvement. Let us know when these are available.

    It’s so simple, it’s genius. Looks real nice, a refined final piece would probably become the standard for splitters.

    hey, those look nice. I appreciate the simplicity and think your going the right track. A few questions: How would you incorporate forward and rearward positioning if desired? It is hard to have a “one size fits all design” on a splitboard. I just wonder about people with different sized feet…. I guess you could have S, M, and L bindings? Also, is snow clogging more of an issue than stock sliders? It looks like your design is fully closed off where voile uses open rails.

    Wow, you guys are rocking my world! Thanks for all the great feedback. Here are answers to your questions:

    P420: Will they be for sale?

    I’m hoping to start selling sets in the springtime after some modifications and giving them a really good beating. To sell these bindings I need to obtain a license from Voile, just like Never Summer, Prior and Venture. Let Voile know that they should let Spark R&D join the club!

    SRA: I was wondering about the bindings while in the board mode. From what I know of the Voile pucks, there would be a space between your bottom plate and the top of the board. Have you thought of putting a piece of UHMW to fill in this gap, or shortening the voile pucks?

    There is a small gap now which you can see here (http://www.sparkrandd.com/images/height_comparison.jpg) between the bottom plate of the binding and the top of the board. The binding will not roll very far before it contacts the board, making things much stiffer. I do need to maintain a clearance between the binding and the board so it can be assembled, but I will keep this to a minimum. Eliminating the roll is one of the things I set out to do, and in doing so the ride is much more responsive. Shorter pucks or some UHMW shims are both great ways of reducing this gap even further.

    Unruly Baker: The only thing I’m curious about is that it appears the pin is only held in place by UHMW PE. There is a screw in front of it but does it go all the way through the UHMW PE to the AL? I’m not sure how much abuse that would take in ski mode before the UHMW PE starts to deform and open up or crack. Do you have any plans for reinforcing that area?

    I do indeed have plans to beef up this area of the binding. That screw does go between the aluminum pieces. I’ve been really impressed by the UHMW, which handled tele turns with a 50 lb pack, but having some more structure there would put me at ease. I’m going to have the baseplate and lower plate join there to make sure the UHMW bearings are well supported.

    Killclimbz: The front of the binding does look like it could bind up in skin mode, the front of the toe mashing up to the ski itself.

    My toe does contact the board at a smaller angle than my standard setup. However, this makes tele turning easier as I can put more pressure on the inside ski. I will have to supply some spacers so people can raise the touring bracket off of the ski and have their toe contact the board just how they want it.

    Affix Snow: Is that the hot water music logo?

    Nope, here’s hot water’s and the spark logo next to each other.
    My logo comes from an industrial fire hazard sign.

    Affix Snow: Could you lose the bottom plate?

    The bottom plate is what engages the pucks, just like the bent under tabs on the slider track, so it’s pretty important. There’s nothing that says it couldn’t be shaped differently to save some more weight. I’m really more concerned with the binding being super bomber than I am making it super light.

    BCRider: What’s up with those cotter pins?

    That’s what I was able to whip up in the shop. I would like to use a pin like the Voile ones, I think they do a good job and are easier to use with gloves on than cotter pins. Pin manufacturers are happy to make custom models but they usually have minimum order amounts. This is one of the things I have to get figured out here in the near future along with sourcing straps and highbacks.

    Endo: How would you incorporate forward and rearward positioning if desired?

    The heelcup can be moved forward and backward to get your foot centered. I ride a size 9 boot, this model would accommodate a size or two above and below that. I do plan on developing a number of sizes so the munchkins and the sasquatches can have bindings that fit their boots.

    Endo: Is snow clogging more of an issue than stock sliders?

    There is a vent on the rear of the binding which can be seen here

    Also there are two thin blades of aluminum that contact the heelside puck shown here:

    These blades cut through snow and ice that might collect on the pucks, rather than the wide tab on the slider track which can trap snow against the puck.

    Keep the questions coming guys, I appreciate all of the suggestions. Powderjunkie, I don’t think I could ask for any better feedback!

    Toe cap straps would be a sweet matchup with binding but not necessary.

    Overall it’s a very cool design.

    Hopefully Voile won’t kill ya on the license. I know it’s pricey and rightfully so for other companies who are making splits. You are not making a splitboard but you are offering a modification that as far as I can tell Voile does not want to get into.

    Of course you want to be straight with them.

    Nice job, looking forward to seeing a market product.

    Wavy-

    We’re working on the split specific strap binding now. If all goes well we MAY have something for next fall, no sooner than that.

    Snowfun-

    We’re very open to any suggestions on improving the hardware and lightening the split. Many changes have been made over the years, and you can bet that improvements to the hardware will continue as well.

    Competition is good for consumers. Or maybe it’s a partnership waiting to happen. 💡

    Cool.

    I was just ribbin’ ya about the logo. 1st thing that came to mind was hotwater…. 😀

    What kind of Liscense do you need to get from Voile?

    No offense taken Affix.

    Voile has their board and interface system patented. Selling other stuff that is compatible with their system requires getting a license from them to use the patent. Without that selling the bindings would be patent infringement, and if they wanted to they could sue me for 2.5 times the money I made selling the infringing item.

    I’ve been in touch with Wally from Voile and he’s a very cool guy. He’s been checking out the design and thinking it over while on vacation. I don’t want people to think that I’ve been heckling them for a license and they won’t give me one, we’ve really just started talking. I am trying to gauge public interest and see if people want more players in the game producing equipment. Seems like you do.

    So, I have some questions for you. Who makes the best straps? The set I have on the proto right now are really comfy, but I don’t have any long term experience in terms of their durability.

    Also, if you had the option, how many people would like to be able to lock their heel down? I’m thinking of something that would add just a little weight to the system, but if you were a true free heeler you could take it off the board and have zero weight penalty.
