I used a cheap 550 brushed motor from a RC car and am currently using a 4 blade nylon 50mm propellor with a 4mm to 3mm reducer to fit the 3mm prop shaft.
Just curious, but what is/was the wheelbase for this powered truck frame in the video?. I ask, because I'm looking to power up some HO scale MU coaches and maybe a couple of Box cab electrics.
Hi there, the motor is a '12V 030 Micro Motor DC, 1.5mm shaft'. There is a complete list of parts required on the Thingiverse link in the video description.
Hi there! I have had good success with just coating the outside in epoxy, however coating both inside and outside may help with longevity, especially if you do get a bit of water inside.
Maybe you can use gear motor instead of normal motor for a more sweet, gradually decreasing speed stop like the real locomotives. it would look super realistic. Hope you try that out! gday
@@warebuilt8007 ah, thanks. So, are you using a worm and straight spur gear? Shouldn't it be a specific worm gear instead of a spur gear so that it mates with the worm correctly?
@@osmanpasha_diy Both the worm gear and the spur gears selected have the same gear pitch, so they mesh correctly, the only major difference is the shaft diameter, the motor is 1.5mm and the wheel axle is 2mm.
@@warebuilt8007 what I mean is that teeth of the worm are skewed, and so teeth of the gear must be angled as well. Them being straight might account for the noise
The real challenge is to do this for 3-rail O-Gauge. I'm already capable of scratchbuilding carbodies, and I'd like to try my hand at powered units (such as electric MU trains) but finding a means to power them has been a show-stopper--the only ones out there in 'O' are 2-rail, and even those are hard to come by. I've seen photos of one hobbyist's project that mounted can motors axle-hung style (like the prototype) on G gauge wheelsets using strips of brass, but nobody's been able to do it in 'O' since some outfit called 'Methodology' marketed a line of slot-car motors geared to O-gauge wheelsets back in the 1990's.
Interesting concept, I have a few ideas, but lacking access to 3 rail track means I have no way of testing. From memory, I went through 9 revisions of the original design to gain a workable prototype. I would imagine a brushed slot-car style pickup or two could be used for the centre rail, larger dual shaft can motor, bronze bearings & gear to match the axles would be a good starting point. With the larger size, further development to incorporate secondary gears/shafts would give better performance.
wow... ive spend hours designing my own... and then you come up with this! great job! i feel like i've designed a special ballpointpen and you've shown me a pencil :) oh, and thanx for sharing it as well!
Good question! The chassis could potentially be modified to fit a brushless motor if a suitably small/micro brushless in-runner motor could be sourced.
You did an awesome job on the locomotive and even more awesome that it runs I scratch build trains out of soda cans and I just subscribe to you and have an awesome day my name is Nathan
