We're done!
I'll bring the post up to date before posting finished images.
First, I wrapped the hammer/axe in plastic, and then attached it to the handle, along with the final handle piece. After glueing it all together, I applied some filler in the seams, sanded back, and then added a little XTC-3D to the seam, to help blend it back in. I then sanded it back a little more, and applied a little primer to the joint. It was now ready for painting.
Painting the handle wasn't too complicated, but involved a little trial and error.
I started with a base color, and then worked a mixture of washes and dry brushing, to get a good variation in color. I also used some lightly diluted paint, and rubbed it into certain areas, achieving a sort of stained effect. This helped to bring some of the highlight areas back up in color a little, to give yet more variation.
Once I was happy with the handle, I gave it a matt clear coat. Once dried, I could remove the plastic, and then do a few final touch ups on parts of the handle which were obstructed by the plastic.
After that, I done some light weathering on the Axe and Hammer, and that was it. Stormbreaker was finished!
