Guns & cupolaOn the tankís bow I wanted to make the sponson mounted 75mm gun able to pivot and elevate. The kit was designed to have this part static and the rotor was molded into the hull casting. I had to first remove the molded in rotor and a replacement was fabricated out of a large diameter PVC pipe. The gunís elevation rotor was fabricated out of a turned resin disk. On the interior, an extension spring was added which prevented the gun barrel from drooping downward. I down a barrel out of PVC and fitted it to the unit. The new unit was installed to the hull via a single counter sunk bolt to the hullís roof. This bolt would be covered up with the top rotor drum detailing, and a lock nut was added on the interior portion to keep everything in its proper place. The rotor overhanging roof accompanied by body work and cast texture was applied to the sponson completing this portion of the model. Once the sponson gun was completed I was then off to finish off the front detailing. Parts like the bow dual M1919 MG mounts, front visor, corner visor, 75mm counter weight, and early head lights were all tooled up in resin. Other details like the M1919 tripod holders, front fenders, and brush guards were all fabricated out of sheet metal. The front fenders have their rigidity bulges pressed into them, and along with their interior details all of the visors were made to be fully functional.Once the rivets were completed, all that was left to focus on the modelís turret. The modelís turret was a single rotomold casting that was the correct size and shape. The kit supplies you with a resin commanderís mini turret copula, and 37mm gun mantlet. On the turret itself I fabricated the missing turret molded in details. These would include the lift eyelet mounts, and the right hand side blister. Rough cast texture along with casting numbers completed the turretís body. The turret mounts to the turret via a single bolt and nut which allows the turret to spin freely, but allows the turret to stay affixed to the model. For the tankís 37mm gun, the kit supplied gun mount and mantlet had adequate molded in casting marks, cast numbers and was in scale with the proper proportions. The mantlets gun rotor drum was casted as one solid piece into the gun mount. I wanted to make this part functional so to make the part functional I needed to carefully remove the molded in mantlet along with the optic bar. A new mantlet and optic bar were fabricated and were mounted to gun mount with a custom made bearing system which allows the 37mm gun and optic bar to elevate in unison. The one part of the model that I was looking forward to working on was the commanderís mini turret cupola. The kit supplied cupola turret was a single casting which was not designed to rotate, had the M1919 mount molded in, no interior detailing, and whoís hatches more or less designed to be glued In the open or closed locations. For my build I wanted to have the mini turret be fully functional with interior detailing. The copulaís interior was all scratch built out of styrene PVC, and resin. The cupolaís 1919 molded-in mount was carefully amputated and a newly designed and better detailed gun mount / rotor were developed. The cupolaís 1919 was not only designed to elevate but was also designed to be able to pivot from left to right. These functions were built into the model. For the M1919, I used the dragon 1/6th scale M1919A4 plastic kit. For the hatches I deleted the molded in static hinges and replaced them and the other molded in details with new functional versions. In addition to all of the new additional functions I was also able to make the mini turret fully rotate on the main turret. Retaining locks were added to the copulaís ring which lock the copula to the turret in the same fashion as are found on 1/35th scale tank turrets.
