Custom/Hybrid NuSplyne Driveshafts

[Tyler Zane]

My buddy, Una Panuna Banks, has created a new shaft design and I have been given one to test in my superjet.

This originally came about because there are a ton of blaster 1 guys in my area and they are tired of stripping splines. So far it has been successful in blasters and I do not expect anything but the same in other applications.

The Driveshafts are tooled from oem shafts and the midshafts are made from scratch.

This one is going in a sn with a 148 mag and full 62t 701. Soon I'm swaping in a 5 mil able.

Contact info, Eric (850) 625-6833

Current production is superjet/blaster midshafts, gp800 midshafts, and driveshafts that can be made to any length.

With core $475

Without core $550

28 Years of working in maintenance, and my brain tells me that the surface are you are losing when compared to splines should make this design much weaker, but if it works thats great. Glad to see all the new parts for old skis.

I 100% agree and have had this conversation with him and others. It's definitely a topic and i knew it would get brought up.

If it will last in a blaster 1, I'm sold. There are a couple of these in blasters on big motors getting beat to hell. I know the standup community doesn't have the spline issue like blasters but Im putting one in my ski to support him.

I have stripped my fair of WB1 shafts and they have all been perfectly aligned. It seems to be caused from constant jumping and loading and unloading the drivetrain. Although I have no proof.

I attribute it to weak hulls. I think if the bulkheads where stronger they wouldn't strip them. All the surf blasters around here crack right in front of the bulkheads and after that you can't keep a shaft in it...

I go through 1 or so a year in my tigercraft viper and it always fails on landing a jump. Gonna have two spares made from sit down shafts this spring for spares.

Una has a viper with a tpe in it. He says he didn't even align it just to make a point. I think it's been 2 years since he put them in.

Philip Clemmons has a nuSplyne shaft in a DVX with TPE 1105.

We shall see. I hope they hold up for the sake of the sport.

What portion of the design principle makes this better than splines? (Surface area, contact area, engagement diameter, torque diameter, length of engagement, what..?) Everyone says its better but why? Asking because I've been riding for 10+ years and haven't striped a spline including the early years when I didn't even know how to align a pump properly. I've even owned blaster 1's with 701's to 1200's that went to the surf. no issues. I guess I just don't understand the problem well enough nor how this helps the apparent problem? It looks neat though

Outside of the box thinking Zane,

So I take it he can turn a stripped shaft into the hex and provide you a revised mideshaft and your good ?

Do have pricing yet ?

Looks nice thanks

I get it, I really do. I don't know the logic behind it, but I will get you an answer. I also have never stripped splines... Some of it may be the riders fault. I just know none of these have failed yet.

I'm not saying these are better or the best. I was just hooked up with one and am going to give it hell. I know he doesn't frequent here so I decided to post it.

It's different, and something to talk about. I think the overlap of the hex may be greater than the splines overlap, dispite less contact area. I'll gladly pull some measurements off it if you would like to do the math. I'll see how much engagement it has also.

At least he is trying...

Definitely thinking outside the box, I thought it was interesting enough to share with y'all.

Yes, the idea is to use your stripped shaft as a core. Which I think is brilliant. The midshafts are made from scratch, and are a work of art. This isn't a garage job. I wish I had a better camera.

I'll update the original post with his contact info. He said to just text him. I think he is still working on final prices.

All right, so here is the run down I just got from Una. I'll say now that I gain nothing from his sales and production.

Dude that makes them has been making nuclear submarine parts for 40 years. He decided on this geometry dispite Una requesting splines that where deeper with more engagement (they did make one, tooling was double the cost). He took the entire driveline into consideration and advises the use of oem couplers (cast aluminum) because the billet couplers may make the crank the breaking point, if they are made right and it come to something absolutely breaking. This design has more engaged surface area due to the shallow splines on our oem shafts.

Current production is superjet/blaster midshafts, gp800 midshafts, and driveshafts that can be made to any length.

everybody has spline issues ........but it is mostly an alignment issue, or bent components...

nevertheless great idea and craftsmanship...lets see how it works out !!!

especially like the fact that u can utilize old parts ...

Thanks for the positive vibes, I'll pass them along! He is a great guy, super likeable and has good intentions. That's why I made this post for him.

More pics, up close as I could get focused.

Looks great Zane

Rock Crawlers and other offroad trucks have been using square driveshaft setups forever (in place of splined shafts), same basic idea, just increase the length of the engaged material a bit to retain the strength.

I have stripped splines from motor being out of line, engine cradles or motormounts had moved and I did not know it. Stripped first at 2005 Riot Ride/Lanier Ride. 2 weeks later I installed new short shaft and drive shaft and guess what, got 30 minutes and stripped again.

I met Una at the sebastian ride back in november. he is just one of those people that you meet and instantly like. Supper nice guy all around.

I'll let him know you said that.

u got issues....lol

Great craftsmanship.wonder what tooling he’s using .
Misalignment on this setup will result in more vibrations so possibly more wear but also earlier indication of this.
Is the engagement longer than oem?
