It's going good thanks, I just added you on MSN but yeah, the robot is progressing nicely, main thing which still needs finishing is the drum which is still being machined... it's all done in 304 stainless with tool steel teeth. Couple of big brushless motors to spin it, thick (and I mean thick) titanium armour, and a couple of motors to move it around... pretty simpleminded machine really, but hopefully effective!
