Hi guys - as a first model building a 'whaleback' using a set of plans - being built with my father-in-law.

Its a RAF HSL/ASR - with a 'flat bottom' - thought this plan best for my basic skills in 1/24th scale - any hints or tips please?

We are scrath building hull and superstructure from balsa with added details from 3d printed parts from ebay etc. BUT need some help sourcing 1/24th scale gun turrets x2 anyone able to help - happy to pay a fair price for them. Not happy with just shaping them out of wood and painting them white!

Help appreciated for this newbie

Hello Phillip and welcome to the forum.

I struggled with this one too. My boat is just 16" overall and, I couldn't find any commercial parts for the turret. In the end, I made one out of a car rear light bulb (which seemed to be the right size and shape).

The 'gunner' came from a 1/48 German aircrew set (Revell, I think). I had to do a bit of 'surgery' to get him inside the bulb once the base was removed ("ship-in-a-bottle" style !). I wrecked a few bulbs though in the process... The guns are also scratch built in balsa /dowel etc. The turret rotates, but, the gun barrels don't articulate. I have a long-term plan to use an "Arduino Uno" to rotate the turret in a randomly selected fashion...

Hope this helps - photo(s) below,

What I call "fun scale" (and, started by my son and a friend when they were very young...)

Philip. I seem to remember other people struggling to find turret glass for this, as they are an awkward shape. The light bulbs are great only as far as if they are the right size!

Clear acrylic domes can be purchased on e-bay, which, if mated to some tube (same size) may make a reasonable substitute?

You might find this an interesting read. Not exactly the same as yours but the scratch building of the turret might just give you some ideas:,9758.0.html

The gent who built this also posts on here so he should see any questions you might have.

Hi Phillip,

Is your model going to be static for show or radio controlled if so the flat bottoms not a great idea, at around 35" long at 1/24th scale I don't think fittings would be that hard to find?

Regards Ray

thanks for tips guys - I'll be sure to feedback how this goes. Nice tip about the bulb - can I ask what bulb you used - looks good on the pictures @Dave Cooper 6

@Ray Wood the model is for radio control - but only thinking of powering the motors - not turrets etc

You could have a walk around the supermarket. There might be a vac forming a convenient shape or top that could be used.

Tim beat me to it. When I built a similar model, I went round our local cheapo shop looking at packaging. I used the plastic from small bottles, they were only 1 mm out, quite ok for me.

Hi there

The method I used to create these gun turrets is fully explained on Mayhem on the build I did on there of the 63ft Whaleback launch - but here are a couple of pics to give you the idea. It was done in an oven to warm the clear plastic up and then I pushed the mould into the soft plastic to create the shape of the gun turret. It took one or two attempts but in my opinion it looks far superior than a lightbulb painted.

Going to put the pictures in my album and then I will put them on here.
