Thought I might as well set up a thread detailing the builds of my upcoming beetleweight machines, got 3 (technically 2) on the go at the minute, and I'll keep this updated with progress of the lot! Will probably edit this too when I have pictures of them all in progress.
The first one I'm building is a 4WD lifter with possibly the biggest drive motors you've ever seen in your life. May or may not be an exaggeration. I'm calling it 'Unmitigated Disaster' and it should be... well, an unmitigated disaster. Should be nice to drive about though. 20mm HDPE around the sides for armour, 2mm hdpe base and maybe doubling up for the lid. 3S/4S battery, standard 10a escs and some kind of servo on the lifter. Probably will be pushing it for weight, but I'll cross that bridge when I get to it!

Second is a horizontal bar spinner, Abandon, which will be an aluminium bar on aluminium bulkheads, aiming for about 10,000rpm on a 180mm bar, 400-500g monster. Should cause some pretty nice dents! Got a vague list of plans for components, but the only constant throughout them are the ebay gearmotors, looking at some sub-1000rpm ones to keep speed low as I won't need lots.
The third one, 'Tell It To The Cleaning Lady On Monday' (hopefully someone gets that reference), is actually technically still the second one since I'm just doubling up on bulkheads and basic structure, though it will have a single tooth bar, still at 400-ish grams as well as hopefully somewhere in the region of 15000+ rpm if my calculations work out right on the motor I've gone for, and 1200 RPM gearmotors. It will be utterly ludicrous and wholly hilarious for the three seconds it stays together for before ricocheting off into the distance, never to be seen again. Probably.
Getting started on the first of these tomorrow, so will post results - might have a go at CAD-ing up the other two from the sketches I have, but will definitely try and get those designs up in some form soon!
