OMG...

Did you FINISH SOMETHING!???! :eek: ???

lol

Nice work - as ever - however your youtube work doesn\'t work (From clicking)
For those wondering why- all you have to do is copy the URL and paste it into the address bar, but if you\'re too lazy, here it is:

Originally posted by jamsessionein that motor was extremely picky about operating, and spun the SAG bit at insane speeds.

If you try to operate a motor made for AC on a DC power source it will not always operate. The rotor must be in a certain position for it to start rotating.

Did you try putting a variable resistor (potentiometer, or \"pot\" for short) in line with the motor to slow it down? Using a pot you can slow it down to the speed you want, then use a multimeter to measure the resistance across the pot. Then you can purchase a smaller, fixed resistor of that value.
 
I think this is about right. :)

It\'s a rumble motor from a broken Gamecube controller with a resistor there to slow it down a touch. It\'s whirling at around 120 RPM, if I had to guess - I am pretty happy with this speed, visually, since it\'s not going to try and take off and fly across the table. The motor\'s admittedly a bit large, but I can manage it. I\'ll get to work detailing it when I get time, though tomorrow morning is dedicated to trying to get some stupid Night Goblin Fanatics for my Warphead project. :p

One of the things I did on a bit of scenery was affix a wire to the motor and the other end to the bit I wanted to spin.

Once both pieces were firmly mounted the motor could be set apart from the spinning bit and at an angle.

You might be able to locate the motor in another part of the mini with a flexible wire as the shaft if you wanted.
 
So here\'s a silly thing I need help with.

I\'ve been digging through my Bitz box for useful Shokk Attack Gun parts for Booma. I\'ve found a couple that I think are good from an assortment of different figures, but the problem I\'m having right now is conceptualizing how to mash them all together into a transdimensional gun.

I\'m pretty sure I\'ve mentioned it before, but I want Booma\'s SAG to fire squigs, not grots. I figure it\'d have about the same effect - grots and snotlings go mad in the warp and come out frenzied on the other side because of the things they saw. Squigs would come out frenzied, regardless of whether or not they understood anything they saw. :p

Anyway, to get back to the problem at hand, I\'m basically not sure how to render Booma\'s SAG properly. I started doing scale drawings just to get a feel for what might be possible, and this is what came out:

This is just a very rough idea. I have a couple general criteria for what I think the gun requires (see below) but the finer details are not coming through when I imagine this thing, so there\'s a couple big blank areas on the gun and room for a ton of rearranging.

Here\'s a couple thoughts on the general design of what I think I might like in the final product:

I figure a Shokk Attack Gun would have to be bigger in order to fire something the mass of a squig through the warp, so I was going to make it extra-large compared to the standard shoulder-mounted job.

I also figure that despite being extra-large, big meks are still able to move about on the board with the SAG (though it\'s a terrible idea, since it\'s a heavy weapon and can\'t shoot on the move). Because of that, I figured something that looked tripod-mounted or planted into the ground wouldn\'t make sense - rather, something on wheels that could be relocated if necessary made a lot more sense. I have very suitable wheel bits that I was saving, and this seems like a good project to use them on.

I want the squigs to be \'lured\' into the machine somehow. The initial idea I had was just to have grots feeding squigs into the machine, but then I thought about it some more and realized grots would have a heck of a time trying to force a chomping, angry squig into a hole. Rather, I imagine something a bit more comical - like a grot standing atop the machine with a piece of meat on a stick dangling over the funnel into the machine, trying to get a squig to jump at it and over the opening and get sucked in. Alternatively, it could just be a grot taunting a squig from across a big funnel built into the side of the machine, trying to get it to run across the path of the opening and get hosed up into the machine. Coincidentally, if a grot or two gets sucked in and fired, I don\'t think they\'d be missed.

One of my buddies suggested an accordion-ish bit on the SAG for comic effect (like the squig is getting compressed for firing), hence it\'s presence on the gun (the angular looking thing right behind the motor). I actually have a bit that would work fairly well for it.

Booma has to fit on the base with it. I have a roughly 60mm round base I\'m going to try and cram this all into, and booma\'s got a 25mm round footprint on that, meaning the machine has to be off on one side. The spinny bits can overhang the edge of the base, but the rest of it should probably be on there.

Now, with all that said... I\'m a little stuck, and I need help through the creative process here. The bits with red arrows pointing to them are all ones I have actual parts for already - the SAG spinny bit, the motor, the accordion looking thing, the two wheels and the base. I would prefer to use these if at all possible to make my life easier, though I\'m open to pretty much any ideas - I just need help figuring out the form of this thing, because when I picture it in my mind\'s eye I can\'t quite pin down a proper look for it yet. Help me with my designer\'s block, guys?

You could use the accordion bit on the side and a funnel bit near the ground. Sort of like the accordion bit is used to create a vacuum effect to suck up squigs instead of luring them in. EDIT: On the back you could put a tiny switch (Suck \\ Blow)

Then there\'s a pressure chamber with a little gague sticking off to one side. On the side of that is an aiming bit. If you use the motor it will fit in here.

On the other side of the pressure chamber is a set of successively smaller and smaller pipes at odd angles around a central straight pipe all leading to the spinning bit on front. Inside the central pipe you can use a shaft to transfer the motion.

At this point you could even use gears to slow the motion. The gears could be visible and part of the look you\'re going for.

I\'ll draw a pic...
EDIT: Here ya go.
