Forward - Reverse Chain Drive Concept Video

[Willie1]

I love interesting proof of concept videos of mechanical contraptions. Here's a 3rd worldish level of workmanship applied to proving the concept of a chain/sprocket based forward/reverse drive unit. Bonus points for stick welding sealed bearings into galvanized pipe LOL.
11 minute video - popcorn advised but optional.

The following stamps have been approved for this feature film: 1) 3rd Worldish, check. 2) Proving a Concept, check. 3) Welding directly onto races of bearings, check. I still have popcorn between my teeth, and I hate that.

That is a very complicated system that is very janky at best. I am putting together a electric reverse over the next couple days on my heavy 440 kart. I'm using a 50 RPM belt drive Makermotor which is reversable and puts out 4.4 ft lbs. It will be slow, but it will back the kart up when needed.
