Does anyone have a pic of a 25:1 flywheel? Here’s ours but it’s too wide.
Can’t you separate it into 2 parts? (imagine if you could cut the red beams in the middle) then turn the gear boxes 90 degrees and pull the axels closer together? You are powering the 2 sides separately already, right?
Let me know how it works out
Don’t have a pic but instead of using one long bar with the gear ratios on there. I would instead run two beams sideways so you could compact it more
