Continuing...
Using the template from the 1mm plastic card glue the vacform section and gun barrels to it using the GRP turret as a guide.
Cut out the rear turret floor and trim to fit the new GRP turret floor shape.
To get the floor and vacform section you will need to trim them and file some of the resin off the barrels, this is because the GRP turret is thicker than the original vacform item.
In the upgrade kit you also have three white metal sighting hoods and hatches per turret, a laser cut plastic turret roof cover (I believe Ron does an etched brass version too) and a 3pdr gun kit also made from white metal.
The final vacform item from the Majestic class kits is the turret barbette base which is a simple mark out and cut the excess plastic off job.
The upgrade kit also includes three different sized barbette rings for the turret to rotate on, I've gone for the smallest one for the turret to sit on.
More tomorrow!
