Project HPR 233

[mudl]

Hi Guys

This is a bulding Report of my Bigboat Project for 2015.

Boat is a HPR 233 with electric setup.

First step is showing the Hull.

The Hull is one oft the first 233 which was made by Hans Peter Rotschi.
I think it is about 10 years old.
But the hull is nearly new.
Only some motormounts are installed and some holes are made in the top of the boat.
Material of the hull is GFK with some sandwich material in the front.
I will make the boat inside complete new and make is stronger.
i will show you my work on this boat step by step.

i hope you enjoy the building report


so here some pictures of the hull.

in the next days it goes on with the building

bye

All your toys are awesome. Everything is extra large scale. So, does this mean you'll have a pair of 233 cats?

[mudl]

Hello

no i have only one HPR 233

Before the 233 i built a MHZ Mystic 240 (Monster Mystic)

Very cool project Mudl, those LMT look very promising

hello mudi
wow what a great looking build you have here! i will be watching with great interest.

[mudl]

Hello

so here are the first works on the Hull.

I took out the old Motormounts and the sandwich material in front of the boat.
After this i closed the gaps in the rear end of the boat inside,betwenn the tunnel an the left and right side.
For closing i used a lightweigt putty.
I closed the gaps so that i can lay the fabric over easier in the rear end.
After this work the commplete hull was grind and cleaned inside that later the fabric makes a good connection with the hull.

so here some pictures

The great thing about working on your hull is there's ample room inside. The bad is there's so much sanding to do. Keep up the progress! Any thoughts on color/paint scheme?

[mudl]

Here the next working steps

After cleaning the hull i streghen the seam with a carbon ribbon.
The Ribbon runs complete from the front to the rear end of the boat.
After this i glue 2mm Sandwich material on the tunnel and 3mm sandwich in the upper Deck.

Looks great! How did you reach all the way to the end with that cf ribbon? What tool did you use to stick it to the hull inside of the tips? I'm guessing the hull is so big it's easy to reach, I wonder what I could use for small hulls to do the same thing...

[mudl]

It is not so easy to make such a work.
My hull is very large.There is many place inside.
But my arms are not long enough
For such a work i use very long paintbrushs or a teflon roller

[Fella1340]

I'm really looking forward to see this come together. I've never seen these motors before, all the more exciting! What type of sandwich material was used on the deck and tunnel?

[keithbradley]

Very cool mudl. It will be interesting to see how the Torqstar motors perform in the 233.
Where did you get the collets? These are 12mm shaft, correct?

[nata2run]

I was thinking the same thing Keith. The collets do look like the LMT ones though. Maybe they were modified or the 7025 were supplied with 10mm output shaft?
