On Saturday I started the construction of the rear superstructure which acts as the base support for various components but in particular the single 2pdr gun.
This shows how I have built the superstructure and used a servo to make a very simple semi rotation system all hidden nicely away inside the superstructure.
Superstructure/gun parts from the kit.
One spare servo.
3ba nut and bolt.
Spare hard wood for to screw servo too securely.
Pictures 1,2,3,4 simply show the construction of the superstructure as per the instructions.(However the instructions as most tend to go out of the window as I am building the items out of order to suit my needs)
Having taken care when gluing all the components together I left overnight to set in situ on the rear deck,as after modification this will be the only part of the ships hull that will be removable (more on that later).
Building the servo mechanism was simple really and that I find is the best way to keep it.The more problematical you try to make it the more difficult it is to maintain and repair.
If you follow the pictures you will see that I took the plastic base of the 2pdr and removed the plastic nipple point that fits into the gun mount deck.I replaced it with a 3ba screw and glued it in allowing to set.
Taking the aluminium tube I placed it in my lathe Chuck and then pressure fitted the nut into the tube and again glued and allowed to set.
You should see that this allows the gun base to screw into the tubing.
Having cut two lengths of hardwood I glued them to the inside of the superstructure and prepared to fit the servo upside down.
I was lucky that the aluminium tube is just the correct size for a push fit directly onto the servo motor stub 👍👍
Taking a carefull measurement of the length of the tubing having fitted the servo in place I cut to length and turned the end to ensure a-snug fit.
The tubing was then carefully slid onto the servo stub and the gun mounting dropped over the top and the gun base screwed on to the tubing.
This is all easily removable in the event of any breakages.
Gun deck then fitted.
Hey presto it all fits nicely thankfully 👍
The final media file shows the gun rotating nicely.
So a very simple but effective gun mount.
The same principle will be used for the forward 4inch Breech loading in due course.
Please note all the mechanical fitments are being done prior to the fiddly bits.
This also ensures that the basic all up weight is attained ready for the float out and adding of ballast.
Time taken 4hours.
Take care all and stay safe.
