What's that I smell? PROGRESS MUTHA TRUCKA'S!
Well I got through the July doldrums which I seem to fall victim to every year...
I decided tonight that I will start caring less about what's under the fiberglass - and more about laying the fiberglass!
The tubbie's have long been a burden on me because they were seemingly a large job. Even with my shotty hot wire foam cutter I knew it was going to be a challenge. And... it sorta was?
Basically I started with making a paper template on the side of the ski to represent the basic footprint of the tubbie. From there I used this template to cut out 2 1.5" foam blanks which I sandwiched together and sanded until they were relatively the same - this was done because the later steps would use 1 set of templates so that I could essentially "mirror" from left to right - and without them being nearly perfectly similar - it wouldn't line up.
So with the blanks cut out - I needed to design a double miter'd profile for the tubbie. I decided to opt for a simple Tubbie 1 like design (knowing that I could always carve an extra "chine" into it after it's in place)
To test out the compound profile mitering setup on my hot wire cutter I need to be confident it would work first - Here is my first attempt.
It worked! Hell yea! I've been sweating this step for a month now and I'm glad I just pulled the trigger on it.
Onto the real thing now!
My miter guide rails are in place (top and bottom plane) to achieve a compound profile for the tubbie.
And after some slow hot wire cutting and inhaling lots of fumes that most likely contain bath salts I came up with this:
America -
yea!
So I got the lower profile carved out - the upper profile would seemingly be simpler to set up. It basically follows as such:
The upper inward edge will be the "cut to" edge, so I set up a guide rail parallel to it the entire length.
The lower edge will determine the "girth" of the tubbie from front to rear. I decided to have about 8-10 inches of full girth at the "belly" of the hull per say. From there it would taper to Zero girth at the front, and .5" girth at the rear to achieve a nice body line and hopefully perform street magic and make for a good handling hull!
Laying out the "Girth profile"
Okay, here's where things got sketchy.... Mr. Hot wire decided to be a baby back bitch and snap on me during every attempt to cut this. So it was not the cleanest cut. But at this point - I must reiterate what I said in the second sentence, I really don't give to many
s about whats under the glass now.
You can see the wavyness which was a combination of wire snaps and my poor technique. This was worse - I sanded it down to achieve a desirable surface over 75% of it. the low point will be addressed later on and I'm actually pretty happy with it.
I just wanna mention how I put it on the ski now - I found this stuff called "Carpet tape" which is essentially like the Area 51 of double sided tapes because I had never heard of it before, but damn this stuff is awesome! It's a single layer of fiberglass with super monkey nuts adhesive on it that is ridiculously strong! I will now opt to use this for all "laminated foam" layups I don't have to do from here on out. It attached the tubbies to he hull in such a way that in order to remove it - I will have to destroy them!

Putting it on the ski instantly made it look a lot better!
Like I said - the wavyness looks a lot worse than it actually is! it will only take about an hour of finish work to get it smooth a silk again. I have the ability to shape this however I want - but given that I will have to lay fiberglass over it, and don't yet have a vacuum bag setup to help with concave layup's, I'm going to opt for no concave "chines" like the Tubbie2's have. Lets not forget what else is going on this yet:
Widened Matrix/Rickter/Superfreak Bond rail AND
Lengthened Skags/Deepened Chines
So Either way - I'm not going to need to depend purely on the Tubster's for handling, hopefully I'll help alleviate some "chine walk" by not adding another chine too.
I could have just bought the MIII's or #Zero's tubbies but with my rocker nose mod - I'm glad I made my own at this point!
I'm gonna use the Japanese Samurai saw to cut the right side since my patience is gone with the hot wire cutter - it did the part it needed to (the lower profile) pretty damn well though!
Glad to be back in action here! Gonna try and make some huge progress now! :Banane35:
