Well, I feel silly. Forgot the TOZ-34 and TP-82 use 12.5x70 mm shotgun rounds. I ended up building a 12 gauge TOZ-34. For future reference, here's a handy chart of shotgun ammunition sizes for making future casings.
I need to find myself some 2.08mm diameter rods to convert to 1:6 scale 12.5x70 mm rounds. Closest thing is the straw to a compressed air can, which is slightly oversized by 10 thousandths. Gundam runners are now only applicable for 12 gauge.
On that note, I finished painting the TOZ-34. Built twelve 12 gauge shotgun shells to go with my re-chambered shotgun. Was debating rebuilding the Pancor from a while back. If I do, I now have shells for it. At least that uses 12 gauge.
I properly painted the shells this time and added some depth to the gold paint application to account for the metal casing that Dragon conveniently leaves just to the rim. Now I'm dead set on not buying 1:6 shotgun shells since now I have to deal with bore sizes.
There's a couple items in development right now. I should organize the completed, pending and queued projects in a post so there's actually some organization to this mess of a blog. One of the items I'm attempting is another flower out of Magic: the Gathering cards. The rose turned out well. I figured it's time to try another type of flower. Bad idea.
If you're wondering "Why a lotus?", you haven't been playing Magic. I figured that I should attempt to build one of the iconic artifacts from the game, and something that also doesn't look out of place by itself. Flowers, I can easily pitch away to people. Chairs and golems don't work that well. I also received a generous donation of lots chaff that included 19x Vampire's Bites that I thought would look OK if all mashed together into one lotus.
