finally finished the project of wheels on toolbag.
prototype #1 was a board with caster wheels seperate to the toobag. which was too top heavy. would tip over on any and every bump.
prototype #2 was a solid rear axle (wheels could spin freely) with a fancy steering system up front. that front part didnt work, when it theory it should have.
prototype #3 is actually working semi good. and is all bolted up to the toolbag has type #2's rear axle, and i can dump it right down if i bother drilling another hole or 2. with caster wheels up front. caster wheels are bothering me. wont go over much without locking up. still a work in progress.
so future plans.
put those proper wheels up front. with a nice steering system. (same as a car, but with a pull along set up)
or put those bigger wheels into a "caster wheel" set up. just so they go over everything.
