Spur Gear Drive Train. Has anyone tried these Ebay parts?

Hi, I stumbled upon these gears: image https://www.ebay.com/itm/1-Module-Motor-Metal-Spur-Gear-50-20T-Width-10-Set-Kit-Ratio-5-2-Wheelbase-35mm/262682640209?hash=item3d291aff51:m:mn-FUMHpAVN6NDV3TbS-pVA

Wanted to ask, has anyone ever tried them? Looks like decent solution to make a gear drive… Cover would be perfect, to minimize sound, perhaps and keep it lubed up…

@darkkevind since I think u messed with drive train, u know anyone who have used them before?

Drive ratio seems to be possible in 2:1, 2.5:1, 3:1 and 4:1 increments… just needs to check for correct bore size, so it is not too small.


Sorry, I’ve not tried something like this I’m afraid.

@MoeStooge is your man :+1:

Looked like a lot of extra material and machining. Probably be the last set of gears you would ever have to buy. A flywheel effect for sure.
