tasty progress - 30 minutes in the lathe produces this.
new visceral is just a basic horizontal bar spinner.
drill drives x 2, scorpion controller, 6x a123 cells. blue inrunner weapon. etc. i wont divulge too much of the construction at this stage as its totally subject to change without reason but needless to say the weapon wont be too crazy. just something that works.

Amazing! You can make brushless motors on your lathe _________________ They say that he crossed the fine line, from insanity to genius.

well couldnt be assed finding a decent weapon bar so i just hacked up phailbots steel bar down to 400mm.
bolted an Old Vpulley on with 4x m8s and lathed down some shaft to 25mm to fit in the two bearings i have thus completing the weapon now i have to work out how to mount the bearings to the frame.. which will be interesting

some progress.
Quick cad without the pocket bike tyre armour. itll bolt onto the extended pieces at the front and maybe some other bits. wonder what robot this looks like
the frame pieces un-welded. top and bottom halves
bottom half sort of welded.
one of orbits old disks getting used, solid shaft etc. 6 cells of a123. should be pretty tough. very very small robot as well. a tiny bit smaller then cobra in all the dimensions. just taller.
beware of the disk owning the pully on the motor _________________ Mechanical engineers build weapons, civil engineers build targets

hehe the pulley is carefully placed over the rim not the teeth worst case
i havent cadded it up yet but know how it goes in my head, but the motor mount wont let the motor drop down unless half the thing disentegrates, so im doubtful it will come back to haunt me _________________ www.demon50s.com - Minimoto parts

its not the motor dropping, its the disk rising ;-> _________________ Mechanical engineers build weapons, civil engineers build targets

I can see some ivertability problems there, but it looks very tough! _________________ Australian 2015 Featherweight champion

bit more progress. tops and bottoms are done. will be cutting off most of the extension on the front bit so the tyre can fit on
next job is to weld on the motor mount plates to the top then weld the verticals in to make the frame.
then a few more bracing bits + motor mount on the weekend and some battery mounts also and should be pretty close to done!
motor mount will be a bit of thick L bracket welded to a cross beam with a slot in it for the motor to but up against with some hose clamps x 3 holding the motor on. i think clamping it will be better then bolting it in solid for shock purposes.
im expecting my new a123s to show up soon so i can make up the MEC packs and have some 6 cell packs done.
looking pretty good progress wise. should have it done with time to spare. SHOULD LOL.

not in the mood for robot building but none the less some more done - uprights welded in and the motor mount + drive mounts mocked up. also cut down the huge extensions at the front.
tommorow ill mount the drives, weapon motor and finish up the weapon mount. will have to think of some mcguyver way to remove the motors also. that could be an interesting operation lol.

*hint* for way to remove motors use the paper clip _________________ A journey of a million miles begins with a single step followed by a hell of a lot of other steps so get walking

Yes, plan B with wheel guards; nice work! If the design pan out, It would be worth going to a plasma cut top & bottom, like Angus's latest design. It would save much welding and would be stronger if done right. _________________ Australian 2015 Featherweight champion
