And no offence, but "some ranks in Chemistry" is not enough if you want to cook explosives 
Disposable Drones are the way to go for me.
Yeah, silly me, I bought some Chemistry partly because I thought I'd need it if I ever wanted to cook my own plastique, but now I look again at the rules you just use Demolitions. Oh well, still happy to have Chem to round out Al's array of tech skills.
Anyway, if it's Demo to cook explosives, then I've got a base pool of 12 dice - reckon with a shop and materials Al can cook anything up on less than a day.
But if you want to do the robot thing, more time sitting and drinking beer for Al.
I've also got a few kilos of low-grade plastique back at my place, if we're going topside anyway...though not as much as I'd like...
Most importantly, where are we going to get the gear slots to bring this stuff?
(Unless I don't need to use up slots for my lighter and cigarettes....Aria?)
Anyway, Jack, let me know which way you want to go on the bomb-making. If you do want Al to help, I'll spring for the shop (or hell, why not a facility?), since I'll be happy to add it to my new place anyway. No robots allowed there, though!
Robots are almost as bad as hippies!
