Making of the SNX Hull

[Nate_D]

Since I was waiting on more gorilla glue to cure and I am waiting for the rain and humidity to subside to mold the hood liner, I rough trimmed the foothold setup.

Cams locked

Cams unlocked, footholds slide

Please excuse the dust everywhere, I haven't had time to clean.

I love the quick cam adjustment!

Very cool design, at first I was like those cams r gonna hurt the foot, but I now c hold is designed so it won't lol

Drilled a hole where the steering will go.

Traced out the steering and then back 8.5" to accommodate the steering cable holder.

Cut the tongue out and took the top 1" layer of XPS off. Need to make 2 bends in the XPS. First bend, rigged up an anchor to pull the tongue down over a 3" 6061 tube as the fulcrum. Very carefully applied heat and increased load until the bend I wanted was achieved.

Second bend. Same idea. Fulcrum, weights, relief cuts, and heat.

Couldn't have got any closer on the angles.

3" PVC pipe cut lengthwise down the middle. 40 grit PSA paper attached to the inside.

Here it is after some sanding with the PVC block. Starting to resemble a pole.

Now that the rough shape is in place, epoxy with different thickeners (cabosil, milled fiber, and chopped fiber) used in different areas. A couple of layer of 8oz tape went down under the tongue to reinforce it a bit.

The top is flat right now, but will get built up into a gentle curve. I debated sanding out a another piece of XPS to make the curve, but I only have 1" on hand and the curve won't be higher than maybe a half inch at the most, probably less. Decided it would be easier to do it with body filler than sand down a half inch or more of XPS. Hopefully I can get this to the Duratec stage tomorrow.

Awesome idea with those cams! They get tight enough to withstand a hard kick in?

 

[Nate_D]

They can generate a surprising amount of clamping force and have an adjustable plate to dial in the tension. Only some on the water testing will tell for sure, but they feel very very solid. They are also very pricey sadly.

Inspirational build man, I love seeing updates on this. Keep up the amazing work!

 

[Mud-Nut]

Those cam locks are a great idea! Very cool.

Loving the detailed step-by-step pics.... Keep them coming! You work at an incredible pace.

I have been lurking on this thread for a while. Exceptional work and as mud nut stated you are quite efficient at it as well! One thing that i wanted to bring up is a concern with the foothold. It looks to me like their is going to be a fairly high stress concentration at the 90 degree elbow right above the cams. Any concerns with this area of the carbon fiber cracking? I obviously can't judge its strength from looking at the pictures but thought I would being up it. Keep up the good work! Riding season is almost here atleast in the Midwest lol

 

[Nate_D]

Thanks Bonsy! And yes, if they crack it will be at that 90. The layup for those is 110oz of carbon and a 3mm soric XF core. They are pretty solid, but I won't know for sure until it gets some water testing. Hopefully someone can get it inverted at the Port A ride coming up...

I can always increase the layup, and/or bring the fabric down around the sides by a 1/4-1/2". That would significantly strengthen them, if they need to be.

In between waiting on body filler to cure, I patterned the engine bay and laid up the visual honeycomb.

That lucks so bad ass

This is basically where the pole is at for now. Made a little more progress after the pics. The underside was flat, but I didn't like the look so I added a gentle curve to it as well. The curve on the top flattens down towards the mounting bolt to flow into the rounded center part of the nose. The pole will also have a blue hybrid braided sleeve. The lines on the sleeve run horizontal, which is why I cut the nose visual piece at that angle to match up and tie in the pole. I'm pretty excited about how the pole is turning out so far. Almost exactly how I wanted the lines.

(The lifting body filler/resin has already been tacked back down. That wasn't part of the design...)

Well it looks like both of the options for pumps (Maxx and skat) won't be ready in time for the port A ride. Now I'm trying to figure out plan C. Looks like my OEM I'm using as a jig will have to get new bearings and seals. If anyone following this thread has a 155 setback skat or Maxx pump they want to sell, shoot me a PM.

Just use an OEM 155 for the time being. Cheap and Plentiful, and youll save yourself 2k and might never feel the need to buy a mag.

I have a video one my phone of someone doing 6 1-footed back flips in a row, on a carbon hull with an OEM 155 pump...youll be fine.

 

[iangdesign]

This guy has an OEM 155 pump for sale. @lamar311

This hull looks a little sweeter with every post!

 

[Nate_D]

Thanks! Yeah I have multiple 155 stators and wear rings. Only 1 driveshaft currently cut down to size and the bearings in that unit are dubious at best. I'll probably order new seals and bearings from JetManiac tonight and just run that for now unless a good deal comes my way.

Smart choice Nate.

So I know we are probably splitting hairs here, but... I found that one of my 155 stator sections was made by Solas. Its a little rough and I have know nothing about it. I took some measurements and it has the same size hug as the OEM, but the veins at the hub come up closer to the impeller.

Should I run this or the OEM? Anyone know anything about this Solas?

More progress on the pole. Down to sanding out the glazing putty and then shooting Duratec.
