It was 5 months ago since the previous build of Ma.K - SAFS A8R8 and I think I should slot in sometime for a touch on Ma.K between my Gunpla scratch build project, also as a tribute to Ma.K 30th Anniversary !!
Congratulation to Kow Yokahama Sensei and Ma.K Fans around the world !! ^^
This bizarre armored tractor was jointly designed by Alkett, Krupp and Mercedes-Benz with a silhouette truly worthy of a machine of science fiction.
The hull of the vehicle was covered in variable shielding between 10-40 mm, with a floor shielding of 40 mm designed to resist the explosion of multiple mines. The floor itself was reinforced by an additional shielding of 20 mm inside the machine for added protection.
The first prototype VsKfz was completed in 1942. The presence of manufacturing plates in the vehicle makes it possible to establish the following conclusions: The manufacturer was Alkett of Berlin and on a plate Nmr VsKfz 617 and Nmr 9537 is engraved. VsKfz 617 refers to a Pzkfw 1 tank and 9537 is the chassis number. That would imply that the turret is of an Ausf. A type but this one has the specific characteristics of an Ausf. B; in particular, the hooks of turret (Traghaken) are located on the top and not the side walls of an Ausf. A. The superstructure possesses a turret of the Pz.Kpfw I tank which is equipped with two 7.92mm MG-34 machine guns ensuring the close defense of the machine.
During these ground displacements, the changes of direction were accomplished by orientation of an aft wheel controlled by a system of chains actuated by a wheel. The mobility of the machine was ensured by two enormous discs on which heavy mobile shoes were fixed which were theoretically resistant to the explosions of all mines. These shoes have a form resembling those which equipped the wheels of heavy pieces of German PAK artillery. The principal role of the vehicle was the detonation of mines to obtain a cleared access path for German infantry and AFVs. This was to be achieved by the exercise of a very strong ground pressure using the nine shoes with permanent ground contact.
During the trial tests, it proved that this vehicle was unsuited to the operations of modern mechanized warfare. Its ponderous weight, slow speed, and its awkward size made the Minenräumer (minesweeper) a large target for opposing artillery and the project was thus abandoned.
In April 1945, during their advance, Soviet troops captured this vehicle in the center of the testing grounds of Kummersdorf. Stored a few times in Dresden, it was then dispatched to the USSR. In 1947, it underwent several evaluation tests. Unfortunately, the bad conditions of storage and the carriage had caused irrevocable damage with the mine clearance system so the tests were limited to a short evaluation of movements instead.
The Alkett VsKfz now resides in the Kubinka Museum outside Moscow.
A set of cut out 1mm plaplate . The small center piece will be the template /foundation of a protrude curvy profile.
Adding a pre-shape rib as guide for epoxy putty shaping and sanding .
Initial shape done.
For 2D round profile, measure the desire size and with the elastic characteristic of Polystyrene, just bend with hand to soften the plaplate and try to Over do the U bend , yes Over do . It's much easy to push it out later than outer force to hold it in position.
Have another plaplate with desired dimension & shape draw on it , as a guide for accuracy. Glued.
Same technique applied to another 2 pieces of U-bend plaplate on top of the first one.
Again , Putty added if it have to be a 3D curvature profile.
Again a pre-cut thunder shape plaplate as foundation then sculpt on epoxy putty . I will put extra 2~3mm thickness epoxy to the designed profile , so the following process i will only need to scrap off the extra but need no more topping.
Trimming should be done while the epoxy putty are half harden ( after 1~2 hours curing, depend on how much water you add on when mixing the epoxy putty) As it's strong enough to hold the shape and stay in place , but also soft enough to slice with cutter.
Sanding with file only can be done after it's totally harden (after 4~5hrs)
As usual, sanding with 400 sanding sponge on curvy profile , flat & sharp edges will need sand paper/sanding stick.
