Ah, that makes sense. Knowing me, something was not plugged in a micron far enough.

Wow, 10k views. Das a lot.
Anyway, today will be a CAD day. Since a few are going with it, I was "Inspired" (AKA jumping on the bandwagon) and going to attempt to make something in one of the Autodesk programs. Inventor, Solidworks, I don't really mind.
So, the first design [INSERT DESIGN HERE] A two wheeled speed 900'd (Clone, or something similar in power) steel bar'd pyramid of a robot.
Forgetr speed 900's. Those are getting so rare... You rather should invest in golddust.
The new BotBitz combo looks like a winner.
Yeah, I've seen how impossible to get the Speed 900s are. I'd rather go for a nice clone of the style of motor, something off of ebay. Wouldn't be nearly as powerful as the originals, but if it's stronger than drill motors.
Also, what is this BotBitz combo you speak of? The GM36 motors? Sorry if I've got the complete wrong thing, I tend to do that.
Mario is talking about this: http://www.robowars.org/forum/viewto...1642&start=540
nice find, I never saw any 42mm gearboxes appearing on ebay
They look pretty good. I'll keep an eye on them.
Anyway, does anyone have any idea what the cheapest I can go on a decent-ish pneumatic or hydraulic system? I wish to keep it under budget, but I can have a ram for Xmas, I guess XD
All I need is a simple lifter system (although I can't buy quite yet) or a simple crusher, hence the pneumatics. I'm not quite sure on how to set up hydraulics, as in the pump side, so I'm very willing to set that aside until I get some pneumatics set up.
So, basically, what sort of sizes of parts (Bores etc) and what pressures are good for lifting and potentially crushing? I've heard of pneumatic crushers, I'm fairly certain. I just need sizes and what kind of prices I'm looking at. Apologies for the wall-o'-text.
Pneumatic crushers. I think only the heavyweight Mitril comes close to being a real one. That uses a monster of a ram on full pressure. (140mm bore, 140mm stroke, 8.5 tons of force)
TAN has damaged other machines, but that was more a stroke of bad luck.
But in feathers, pneumatic crushers? I can't recall any succesfull one.
Hmm, a 100mm bore, 50mm stroke single acting ram... a tad heavy, but with 4 tons of force you could do some damage. No buffertank needed, speed will be fast enough to grab and splat.
Use a big servo to open and close the bottle as main valve, and another big servo to open a poppet valve to dump.
I don't think it's going to get any cheaper than that.
On hydraulics. You'll need big pockets for that.
The smallest, affordable gearpump I found was £85, that needs at least a Speed 900 or geared Astroflight to operate.
Maybe that a DeWalt can do the job -team Storm started on such a setup ages ago-
Hmm, I may be able to up the budget to accommodate some safer parts, such as a proper reg and a somewhat decent 3/2 Solenoid. Is it useful to have a QEV on a crusher, or just a plain slower dump valve? I'd assume a plain dump valve wouldn't hurt. Also, is a 100mm bore the absolute minimum for a crusher? Or could I get away with around 50-ish (And above, 63 etc)?
Thanks for the help.
Edit: Oh, and what's the best way of shortening a ram? I may have found one with a good bore, but it's too long.
Hmm, I've been thinking, and I've decided to stick with a plain old flipper/lifter/poppy thing. What'd be the best pressure to make something that can self right, and would a 63mm bore 300mm stroke cut it? I just need the ability to self right, but a bit better than an actuator. Unless I get a lifter/"Crusher" (More like grabber) combo, with a single linac. And two on the sides to self right (Since it has rather flat sides, and without pneumatics can't really move.)
