Yes, another Catamaran Build!

I used CA to tack them in place, and epoxy to secure them.

[Avanti]

can't wait to see what you have planned for your canopy

[ace028]

I was counting on you for that idea, lol jk. Well thats about all I can work on for a while, out of funds at the moment, so there is a lot more sanding and shaping that will take place. Any updates on yours?

[Avanti]

my boat is just sitting as I have too much going on for school right now

[ace028]

Well at least you have a good excuse lol jk. I want to go back to school. Not sure I want to be a mechanic for another 20 years. I think I want to be a engineer, computer, mechanical, electrical.

I don't have much progress to report. I did remove the tube that was for the steering linkage, and I reversed it so that the boot will be inside right next to the servo. I did this because I think it will make for a cleaner, nicer looking transome. I will post some pics when I get some more work done.

I have yet to start on the hatch shape. Its hard to make something symetrical. I will have to carfeully plan it out the best I can.

I also have a thought for my hatch, I was thinking of putting it on hinges, so that it will swing open, and have magnets to secure it closed in the front, and have some 1/18 rc car shocks on the hinges to keep it open, and when closed past a certin point actualy keep the hatch closed. I find that I am always droping my hatch and such. It would be removable from the hinges in case of more then battery changes.
*keep in mind that is will not be a substiute for hatch tape, merely a "cool" factor. If it gets too complicated, I will just scrap the idea, and keep it simple. Any thoughts on why or why not, or any about anything?

Here is some updated pics. I started on the hatch cockpit by making a symetrical cut out base template, then traced it onto a peice of styrofoam, then shaped it to where you see it now. I drew on a window and some ducts just to give it some character to see if it looks ok, let me know what you think of it, good or bad. It is only rough shaped, and not glued.

[Avanti]

Looking good that is exactly what I had in mind as well

[ace028]

Good, I didn't want to secure it if people thought it was funny looking, I think it looks pretty scale. I compared my boat to a racing cat in a mag that took 2 pages, the length was close to my cat so I measured the length of the cockpit to give me a ballpark size, so I didn't make it out of proportion.

I saved the template I made for it if you want it Avanti, pm me if so, I can send it no prob.

I have been really busy with the holidays, in fact still a little busy, but I have some updates to report, I don't have any pics now, but will update them later.

I have glued the cockpit to the hatch, and used some balsa filler to smooth it out the transition, it is only roughed in for now, the whole boat will get the final once over once everything is situated in place.

I got my 1/8 to .130 coupler from my other boat that is still waiting for paint repair from my dad when I visited for holidays, and I confirmed the actual shaft size for my motors which is 1/8 (3.17?) not 3mm. So now I can mock up my flex tubes, but I noticed my teflon liner is the wrong size for .130 cable, so more waiting till funds are appropiate.

In the mean time, my hatch had warped slightly once the glue dried on the cockpit, making the rear of it not sit flush with the deck, so I had to make some releif cuts in the hatch to make the ark match the rest of the boat, then filled in the cut with balsa scrap and then filled with balsa filler, and of course some sanding.

I will be soon faced with the largest hangup, which will be the stingers, I want them to be adjustable, so I'm not bending the tubes and risk breaking the glue in the event of a angle change.

[Avanti]

sounds great, I have not done a thing on mine mainly because parts have not come in so I have no real motivation to finish it.

[ace028]

After fiddling with the stuffing tube, I realize why avanti opted to put his motors further forward, I have found out that the availabe space is really short for my needed bends, so I may switch to .098 cable. My tube will have a "s" bend in it, If I would have thought further ahead, I would have angled the motors down slightly to reduce the angle. Oh well, no pics yet, kind of waiting to buy some tubes and teflon tubing to mess with it some more.

I think my next project will definatly be a fiberglass pre made hull, this project is turning out to be a lot of work.

[Avanti]

you can still angle your motors by putting washers on the bottom mounting screws to wedge it out

[ace028]

Ok, I was thinking of this for a strut, not exactly what I was wanting, but I think it will be the easiest way to do what I was wanting, and it will extend my cable lenght to hopefully reduce some of the angle.

Avanti, I was thinking the same thing, till I realized my motor screws are on horizontal, I'll have to add the other mounting screws as I only have 2 for now per motor, I may be able to use all 4 mounting screws with the washers per motor, but I am concerned that when I tightnen the screws since the motor will be at a angle, the screws will gouge into the carbon, what do you think? Once I get the correct teflon, and a tubing bender for the larger tubes, hopefully I can make some nice mandrel bends, or at least smooth bends, and see how much friction is there.

here are some pics, let me know what you think, good or bad.

[Avanti]

not sure about those struts, but you have to do what works.
you could make some cf wedges for the motor side, and wedged washers for the screw side.

The hull and hatch look AWESOME! that first pic with the side view is great looks like a big Skater.
