Boy, it's been a while.
I have some updates for the gun coming at some point. Until then though:
I wanted to wear the blower to a local con, but wanted to fix a couple things on it first. The biggest thing were the heat sinks for it. When I made my blower years ago, I didn't have many tools. As such I couldn't cut the bevel into the heat sinks to make them look more accurate. This week I spent a night with the band saw and cut the two extra fins off of each of my heat sinks, cut in the bevel, then mounted them back into the pump boxes with modified L-bar.
Here's the shot of one of my heat sinks before:
Here's what the L-bar looks like, which I used to mount the modified heat sinks with:
And here's where we're at now:
I am still planning on going through and redoing almost everything on the actual blower "pack" eventually. These heat sinks will be replaced with more accurate ones, along with the pump boxes, tanks, etc. This is just to get me by for this convention.
