Why did I do this? Because I don't like the look of normal thunder hammers. Their heads are way too long and too spindly. Your mileage may vary, but they really don't work for my taste.
So I designed my own! The dimensions of the block are 8mm long, 4mm wide, and 5mm tall. That makes it have very similar profile to a normal thunder hammer, but it's not as elongated. It's also not as goofy and I hope that it will communicate heft really well.
The hole in the bottom is 1.25mm wide, matching the diameter of Privateer Press brass rods I like to use for pinning. They're thin enough to drill into the haft of an existing thunder hammer.
Here's my best attempt of a true-to-scale attempt at what the hammer should look like:
As before, I ordered these from Shapeways in frosted detail plastic. A set of 12 cost me just over $20 with shipping. That's not too bad. 12 is more than I'll ever use, including putting them on Termie characters.
And of course, credit where credit is due, here's the inspiration:
So much for now, thanks for taking a look!
