STOP! Hammer time!
Although there have been many truly absurd and awesome weapons in Homestuck, the Pogo Hammer was the first we were introduced to. It's always been one of my favorites, and now I have a Pogo Hammer of my own! (It is not as potent in combat as John's, however.
Here it is as early parts. I made all of the parts out of a long 2x4 except Slimer, who I found a thicker piece of scrap for. The heads and rectangular center were made by gluing two square pieces together, then cutting the shape out. I traced the Slimer pattern onto the wood and cut it out with a band saw, then sanded any parts that weren't quite right. I bought the springs from a parts supplier online, they are die springs, super sturdy. I had to stand on them to get any compression.
Slimer is connected to the rectangular center by a dowel rod that goes into holes drilled in both parts. The handle used in the assembly turned out to be an odd size (a bit more then an inch) and I didn't have a drill bit the right size to put a hole in the rectangle. I tried sanding it, but in the end I just had to get a more reasonably sized dowel to work as the handle.
I started painting all the parts before assembling them. I used some spray paints for the black/white/grey parts. After I had painted the ring at the top of the handle, I used a drill to put some metal screws into it that I thought looked good. Painting Slimer was the most difficult part of the process. I printed out pictures of him to the scale I wanted, and cut them out with a craft knife to make a template. I used a spouncer (sponge-thingy on a stick) to paint him without leaving brush marks, first doing a full coat of green, then dabbing black on with the template to protect areas I had already painted green. After that, I did touchup work with some smaller brushes. When I put the parts together, I used wood glue for all the wood-to-wood connections, and Gorilla Glue Epoxy to connect the springs to the hammer heads and rectangular center piece.
After this was done, I got picky and tried to do some fixing on the paint after it was assembled, which usually made it worse then when it started. I managed to get everything together eventually though. Once that was done, I cut grooves in the base of the handle and drilled holes perpendicular to each other to hold the grip in place. I made the grip from a material called coolmorph (http://www.coolmorph.com/), which is a nifty thermoplastic that becomes moldable when you heat it up in hot water. I heated up some of it, wraped it around the handle, and scupted it into the shape I wanted for a grip. Then I painted the handle the same color I used for Slimer. Finally, after all of this was done, I put a few coats of a clear sealer to protect the finish.
So that's what I've been working on for a while. I'm excited to share it with you guys!
