This is the basic Stormlord Heavy Tank with the Vulcan Mega-Bolter. Normally I like to replace these types of barrels with brass tube, but the molding on these are just excellent.
The Banehammer Super Heavy Tank. This short barrel is a Tremor Cannon. With this weapon, the casement can be at the front or rear.
I realized I didn't show you how the barrels were made interchangeable. The base barrel had a large brass tube glued inside. I had to take care that the tube followed the axis of the barrel, otherwise the other barrels would be crooked.
Part 3 will be the sponsons, and any other details I may have forgotten to snap. After that, it's just painting, though I may make a video of all the configurations before doing that. I think all the conversion work will show up better in its natural state.
I'm open to suggestions for a paint scheme. Don
