BryanKrueger Posted March 13, 2019 Report Share Posted March 13, 2019 I have been working on this for the past few months. This is my attempt at the KV ZIK-20 SPG. A concept that only got as far as a wooden model. The design came out of the same program that ultimately lead to the KV-14/SU-152. The development history can be found here:ZIK-20: Assault Alternative The goal was to mount a 152mm gun into the hull of a KV-7 since that design path was a failure. It's a questionable design. Most of the ammo was stored in the floor which made it uncomfortable for the crew and the fuel tanks were mounted in the in the front corners of the casemate which would make things unfortunate for the crew. It has a crew of 6 with four crammed into the slab sided fighting compartment. I created the 3D CAD drawings in SolidWorks based on the few drawings of the ZIK-20 that are available. Most of them don't match up to one another so I had to adjust some of the features to line up. As far as I know, there is no top down drawing of the roof plate. The locations for the top hatch, vent, and rotating periscope, and fuel caps are interpreted from cross-sections. I added the periscope sketches where possible, added a second crew hatch and rear loading hatch to make life easier for the crew. Link to comment Share on other sites More sharing options...
BryanKrueger Posted March 13, 2019 Author Report Share Posted March 13, 2019 I sent some of the parts to be 3D printed These are printed on the Form2 3D printer using a "dental" resin which can print finer details. The downside is it's more brittle and more prone to warp from UV. I'm kept them stored in a box in the closet until I got primer applied. I was super excited the barrel rifling printed. There is suppose to be a small gap around the recoil mechanism cover but it filled in on the print. I will need to carefully scribe this detail.

BryanKrueger Posted March 13, 2019 Author Report Share Posted March 13, 2019 There was mention that there was some confusion at the factory over which KV hull they were suppose to use. Production of the KV-1S hulls were just starting but this design bureau didn't get the memo. I decided to base this ZIK-20 on a KV-1 with flat rear hull - it was what I had in the stash. The KV went together quickly even with all the clean up required.The roof was also 3D printed but had a slight bow from the build. Hot water did not straighten the part out so I glued it to a piece of 1/8" acrylic. Link to comment Share on other sites More sharing options...
BryanKrueger Posted March 13, 2019 Author Report Share Posted March 13, 2019 Progress with the casemate assembled and some welds applied. Tracks are just place holders. Model has been detailed with an Eduard PE set. Welds are Miliput epoxy putty. Link to comment Share on other sites More sharing options...
BryanKrueger Posted March 13, 2019 Author Report Share Posted March 13, 2019 And here is my current progress. I added MasterClub Tracks and lots of MC rivets. I used the Royal Model fender set but it was a bit simplified. I had to add the missing angle iron sections from Albion Metals extrusion. Nothing like buying aftermarket for your aftermarket set. The tow shackles are from Aber. Eduard PE was used for the basics like vents screens and hatch details. Other bits are scratch built. I still need to add some additional details but getting close.

WildBill50 Posted March 14, 2019 Report Share Posted March 14, 2019 Fantastic! That mantlet looks huge. It looks like iw would weigh more than the gun. Keep it going. Nice work! Bill Link to comment Share on other sites More sharing options...
BryanKrueger Posted March 15, 2019 Author Report Share Posted March 15, 2019 Thanks Bill. I've added a few small items like light, horn, and grab rails for infantry. The figure is from MasterClub. it's a nice natural pose that fits well with the tank. Link to comment Share on other sites More sharing options...
