Small Tug ... Grows up?
« on: August 26, 2012, 10:14:17 pm »

Could not resist  %)

As per my original post http://www.modelboatmayhem.co.uk/forum/index.php?topic=34679.45 where I speculated whether or not this hull template could be used for other models.

Below card samples of my attempts to build a boat on the lines of a Macduff 12 Metre Work boat

http://www.macduffshipdesign.com/tugs/2.htm

I shall be building to a scale of 1/35 which means I have to stretch the original templates slightly. The bow is much rounder and the stern has no taper as can be seen on the deck of card model 2.

Seems like it might work although I may have to fudge a bit around the bow, not a problem I'm after a protypical hull and deck lay out. As per the original this is to be a fun build.

Next step - try it in plastic card.

Hmmm - interesting idea - what thickness of plasticard will you be using ?

Regards,

Ray.

Hull has gone together with ease apart from bow area as suspected.

Don't think its going to be much of a problem to fair (fudge) it in !


I'm using 1mm thick plastic card apart from deck (ran out of 1mm). Deck will two layers of 0.75mm.
The last pic hopefully shows the 1.2mm plastic rod I have clued into joints to give a larger contact area for glue.
You can also see the fudge material (plastic padding) in bow area to strengthen/fair in bow.

Rather than cutting frames my thoughts are to laminate ribs in place to stiffen the hull. I didn't do this on the first
one and I don't think its probably necessary.

Success !

Managed to find time to quickly smooth out the hull and I'm well pleased with the results.

Definitely on the lines I was looking for, what do you think ?

Away now until the weekend  :((

Right back home and back to work  ok2

I wanted to get the stern area of the hull to take on a concave line as per modern twin screw tugs.

Not sure how clearly the photos are going to show it but here goes.

Start

NASA plays a part ! Two spray cans pushing the hull up into required position.

Ribs laminated inside

Finished hull - well pleased with results.

Yes I did say twin props, not decided yet whether to go for fixed or steerable Kort nozzles. Anyone got any thoughts?

Been working on one of the steerable Kort Nozzles, pleased with the results.

I hope the pics will show the method of construction.

Finally managed to get some work done!!

I wanted a more modern stern, so I filled the stern quarters with 'Easy sand' and then cut and sanded until I got the shape shown below.

Ordered the running gear tonight from Cornwall Model Boats so I'm expecting it tomorrow morning  ;)
