Topic: Dread's 2nd model,a quasi-type 24 frigate (Read 14355 times)

I've decided to try building a semi-scale Type 24 frigate,based on GG's plan called the Paladin from MB Oct 2005. I've made some adjustments to the hull shape as follows:- The base of the hull is still the same at 3" wide,but I've used 9mm balsa for the hull base instead of just 6mm,and the deck level will be 3.25"wide in order to impart an outward lean to the hull sides. I've also lengthened the stempiece at the upper level,in order to increase the prow angle of the bow. The other adjustment that I've made to the plan,involves the stern of the boat,whereas GG used a simple sloped section from the hull base up towards the deck level,I've gone for CH's stepped rear hull shape. The reason for this is that it allows you to fit a stock rudder with no problems at all,provided that you reinforce the balsa with light ply first.
The reason for doing this is quite simple,having seen the astern response of my corvette,I'm going with what works for me. I'll post up pics of the build as it progresses.

this was the first plan build that I made. It was built the same year as the plan came out, and was builtas standard at the St Albans show in one weekend! This boat became the nightmere boat on the lake, zooming round, leaning right over. Great fun. Even in reverse it was fun!! It had a standard servo and a zebra 40 mhz radio as set up with a jr 400 size motor. On more that one occasion she was sunk by being rammed amidships, and even went up against a Happy Hunter, with dire results!!! The best one was by mistake, when running parallel with the Happy Hunter, I turned in to her stern and was drawn in to her wake wave, Paladin became totally submerged running underwater!! as soon as the Hunter manoveured away she popped up and carried on sailing.we done thi several times before she became waterlogged and stopped working!!! really good little runner though!

Go for it Dreadstar - I loved what you did with the Vosper, & I'll be watching with great anticipation.

Ok,as promised here are the first pics of the build. In the second pic,you can see the kick up that i was referring to.

The next three pics are just of my motor line up,waiting for the epoxy to set. I'm going for a 380 motor running on 7.2V with a 30mm Graupner prop on this boat.

I had to go and buy more balsa today,because I'd forgotten the allow for the increased size of the bulkheads....DOH.

The foredeck has been fitted,and the reinforcing ply plates for the rudder have been done. The motor mounting block has been glue in place,along with the servo cage. The rear deck,which can be seen below the hull has been cut out,along with a recess to allow me access the the rudder mount. In the third pic,you can see the amount of flare that there will be on the hull sides. Hopefully this will help to push the water away from the sides of the hull,and aid efficiency.I've dug out another ESC and 2.4 GHz receiver for her. I think that I may need to build a wee shelf,to keep the receiver as high as poss in the hull.

Coffee time I think,then carry on with some more of the build.

Rudder fitted;coming fitted around opening in deck;rudder linkage installed and top deck now glue in place.

That's all that I'm going to be able to do for now,until the glue sets.

Another deviation from the GG plan,is that I'll be plating the hull with full sheets of balsa,rather than the patchwork quilt way of doing it. The wee Vosper has had several heavy hits to her flank whilst playing tag,and she's come away with no damage whatsoever,including a full speed strike from my Veron RBR.(Never let youngsters play with high speed boats,especially when they've never sailed before

). For the prow of the boat,I'll again be reinforcing it with brass angle iron,as I have on all my boats,it really does save the bows from damage, especially when the sides of your pond are slopes instead of vertical edges.

And don't forget to cover the hull sides with Dope and Tissue paper, stiffens the structure and gives a good surface for painting.

Regards Ian.

Daft question I know,but would yacht varnish and tissue work just as well? I don't have the luxury of an outdoor shed or a garden for that matter,so everything has to be done indoors. The varnish is virtually odour free,though the paint isn't,so just how strong a smell is dope?

Circlip · « **Reply #9 on:** July 02, 2010, 06:06:43 pm »

Dope tightens the tissue up and gives a surface that will grip cellulose spray cans colours. Yacht Varnish is a finishing coat.

I sanded mine down, sprayed varnish, sanded varnish sanded then sprayed with halfords primer and the green top deck handpainted with snot green from citadel......comes up a treat!

Dreadstar · « **Reply #11 on:** July 03, 2010, 09:00:03 am »

In the case of the Vosper klunk,she ended up with a total of 6 layers of varnish and two of paint,(hand brushed varnish,not spray).

First hull side fitted,view showing the hull shear and transom fitted and sanded.I was at a wedding yesterday,so I couldn't get very much done to her.

Klunk · « **Reply #12 on:** July 03, 2010, 02:03:40 pm »

right think I might do one of these again, original is in drydock for overhaul!

Dreadstar · « **Reply #13 on:** July 04, 2010, 08:56:22 am »

2nd side fitted and taped up whilst the glue dries.

Tape removed and hull sides rubbed down,and keel edges rounded off.

Cool stuff ..................... will be fascinated watching this!

Dreadstar · « **Reply #15 on:** July 04, 2010, 12:35:15 pm »

Please excuse the fact that the superstructure will be very much a dead eye reckoning guestimate of the type 24. I'm trying to keep this as simple as possible,though closer to the drawings than GG got. On the Paladin,the anti-ship missiles are on the foredeck,rather than abaft the funnel,which sits amidships,rather that bolted onto the hanger.

Does anyone have an idea as to what the structure forward of the funnel is supposed to be?

Netleyned · « **Reply #16 on:** July 04, 2010, 01:27:45 pm »

The structure with the radar dish on the front is the director for the gun
On my last ship I had the dubious pleasure of being harnessed to the top
of one with a 35mm movie camera with a 1000mm lens to photograph
the shell bursts around the aerial target.
The director tracks the target for the gun and the movement can get quite
violent. It's also rather noisy!

Yours Aye

H ya there, By you are getting on quick and really well with this

Looking good!!!!

If you are referring to the structure which has a cross on the side, that (I believe) are air intakes for the gas turbines - these are much similar to those which the Type 21 frigate had when she was first designed - owld hen coupes - as my dear old dad used to call them

Whoops another one of those days
Read the question as forward of the mast
John is correct air intakes.

Thanks for the reply's lads. I'm working on her superstructure just now,it won't be overly accurate,but should be a good approximation of her when it's done.
How thing are looking just now.
