Has your hull the same depth as a standard Springer or have you made it slightly deeper? Some dimensions of the hull bottom would be helpful.

The hull was drawn using standard dimensions I just flattened the forward two sections of the curve, I wanted to see if it made any difference to the submarining tendencies, that I still don't know yet as it's only been in the domestic test tank, I must get her down to the lake.

Interesting as I have never quite believed the inverted aerofoil hull shape theory.

radiojoe · « **Reply #128 on:** September 12, 2018, 01:45:52 pm »

Well I'm convinced the inverted aerofoil shape produces a suction at a certain speed and I wondered if having flat areas may break up the flow under the hull when I get back from holiday I'll test her at speed at the lake.

Be interesting to see how tests go

Gardener · « **Reply #130 on:** September 29, 2018, 03:06:51 pm »

Have you tested her out yet ?

Gardener · « **Reply #131 on:** September 29, 2018, 03:16:12 pm »

What thickness ply is she made from Hull, sides etc ?
Thanks
Dave

radiojoe · « **Reply #132 on:** September 29, 2018, 08:07:21 pm »

Hull sides / forward and transom are 1/4"ply bottom and deck is 1/8" ply, superstructure is 2mm ply,, so far only tested in domestic test tank(bath) no leaks and controls well, almost turns in the width of the bath with the fish tail rudder, now I'm back from holiday I'll get around to taking her to the lake.

What did you make gunwales out of ?

Meant bulwarks

radiojoe · « **Reply #137 on:** January 28, 2019, 10:29:58 pm »

Hi Dave, they are made out of 1.5mm styrene sheet, the capping's are cut from .5mm styrene.

Made a start on the deck, and fitted the access upstands, I thought I'd have a small hatch over the tiller flat just big enough to get an allen key in just in case, next I'll make the forward rams and fit them before I start the superstructure.

Have you used pins to fasten the deck on while glue dries?

Started the wheelhouse, cutting out the windows and doorways was tiresome probably would have been easier in styrene but I like working with ply, ultimately I think it makes a stronger structure, fitting out the wheelhouse will be done using styrene.

Joe

Joe, how do you cut out your plywood, for example the thicker sides, and the thinner wheelhouse etc?

And then how to get them so accurate??

radiojoe · « **Reply #141 on:** January 06, 2020, 01:45:35 pm »

Hi Dave firstly no pins used on the deck it was just weighted down while glue set, cutting plywood depends on the thickness 5mm and over I use a electric scroll saw or a jigsaw, 2 or 3mm can normally be cut with a Stanley knife or similar, cutting out windows etc. I usually drill holes in the corners inside the marked lines then use trimming knife or scalpel to cut out it can then sanded to the line as I said a lot of widows to cut out is tiresome but if you take time over it it's very satisfying, hope this helps.

That’s fantastic Joe
Many thanks!!!

dave parker · « **Reply #143 on:** January 06, 2020, 03:48:38 pm »

When you prepped for paint, was it a few coats of sanding sealer sanding between coats, or did you use dope and cloth??
Thanks
Dave

radiojoe · « **Reply #144 on:** January 06, 2020, 07:30:12 pm »

Hi Dave nothing so grand as all of that, I just use Halfords spray cans the superstructure gets two or three coats of grey undercoat and the hull four coats of red oxide undercoat, the finish coats are Humbrol Acrylic paint, I never use clear varnish on any of my models for the amount of time they spend in the water it's never been a problem.

Finally got Gala Girl to the lake today her first time in water other than the bath, I went to pick up my meds this morning, as the pharmacy is close to Walpole Park I popped in to the car park next to the water and thought how ideal it was warm sunny and just the hint of a breeze, so strait home and a quick charge of batteries and down the the lake, she had already been trimmed so strait to the trials, I'd say from the off she performed as predicted and as a Springer should not too fast on full throttle and highly maneuverable, I didn't see any tendency to submarine with the modified Springer hull at her top speed, but then she is only 6 volt PB so if she was changed to 12 volt and a bit faster I can't say, to summarise I have no plans to increase her power as I think her performance was fit for purpose, she would get out to a broken down boat and push it back.

Great day for a maiden voyage Joe. She looks the business.

(I've sent you a PM by the way.)

looks good Joe
sailing at last !

ballastanksian · « **Reply #149 on:** June 25, 2020, 07:07:34 pm »

I remember your build of her Joe! I am so pleased you have finally got her bum wet and that she sails well.

I reckon you have the right power/speed, as if you wanted loads of speed you would have built a cruiser or speed boat
