Hi just thought i'd share a new build of mine, it's a 1800mm x 560mm x 200mm deep offshore cat, at the moment just working on the plug, but hoping to create a mold then fitout with some RCMK 520's, made the dimensions so you can either put a twin in the middle twins in the sponsons or single cylinders.
will get some photo's of the underside once the putty sets on the deck.
This will be a long build but hey it's worth it.
Yes i will be selling these once i have proven it all, and looking about the $450 AUD mark ???
Comments are always welcome

Patience is something you have to have when building a Plug-Mold, it is so easy to get too keen and mess a step up.
Gee Roddo what took you so long???? i've been here for a whole day!

I am anticipating to have the plug ready for molding within the next couple of weeks, this cold weather has not been helping with the curing of the epoxy.

I was going to put about a 30mm wide ride pad on the bottom, what is everyone's thoughts on this ??? should i go a little wider or narrower ??? I know the RCMK Hydrolift is about the 30mm mark, but it is also 50mm shallower in total height, and 25mm shallower in the tunnel. Anyone got an input.

Thanks for adding in.

Hi Mick.

No that's a <font size="2">CAT! That hull must be for big oval racing...?  We race short sprint racing "M", but wish we had big water to run those big scale off-shore set-ups!!

If i may ask, what is the core/base, and what is the putty to smooth things off?

Iv'e always wanted to build my own hull......

Hi George, yeah i know it's a cat, i use a variety of mediums to build up a plug, anything from plywood ( this is cheap) MDF ( really dense manufactured wood) and surfboard foam, it is really up to your imagination what you use, it is easier to use plywood to get the main shape then fill in the blanks with the rest.
For filling you may use a epoxy filler, or car body filler, plasterboard filler, basically anything but you have to be careful here so it doesn't react with the fiberglass.
If you were going to build just one i would just use plywood and use that for a hull,
Making a mold i would have to say isn't the cheapest way to go, i just really enjoy the build and the satisfaction of constructing something myself.


Have done a little more , got the bottom trued up so now will start on the ride pads and lifting strakes, i have so much dust from sanding on the shed floor it looks like i have had a snow storm in there.

Hi just thought i'd update some progress, lifting strakes are on aswell as the ride pad, got some more sanding and filling to go but getting there. Hoping to get back to the top within the next week or so then get onto the molding stuff,
Mick

Hey Mick, looks great. I could just imagine all the sanding that goes into making a plug, oh and time. And $450 for 1800mm boat, cheap as chips.
As for hard ware like drives, are you going to make your own or would could you use for example mhz drives etc?.
Ill be watching this one very closely.

RE: 72
 
Hi Mate, i was thinking on using the RCMK Drives, but was also playing with the prospect of making my own, just not sure i'm that good enough on the mill / lathe.
Still trying to figure out how i'm going to create the flange for the upper / lower halves of the mold??? i'm thinking on using Alluminium and plasticine ??
Thanks for the coments
Mick

Contact DreaminHemi he did a whole thread about molding a cat and how the best way is to do it. Was very clever.

Hi Dont suppose you have a link to his thread do you? Think i may have it figured out but we will see when it comes to practice.

Cheers all

RE: 72
 
great project!
I have been following your posts. I noticed on the last set of photos you have cut out the pieces of wood that follow down from the end of the sponsons to the rear. Giving you grief sanding?
Keep the good build up.

Thanks heaps Cobus, lots of really good info there, certainly made me rethink how i am going to mold this one.Mick

Hi, bottom is done! man i hate sanding, will have some pictures up within the next day or so, now it is back onto the top and cowl.
Sorry for the long waits but this is a little bigger project than i'm used to.

RE: 72
 
HI Micki,
Finally found it. Now I can keep up with the build. What is the deepest part of the sponson in relation to the inside floor (1,2,3,4")?
What is the cowling size? Will a S520 fit down in it without cutting on the hull sides?

Thanks,
Pat
