Anyone here ever built a chain driven axle to turn car tires???
If so, how did you do it?

A high school auto shop class built a 3/4 size 30's roadster powered by a Honda 750 4-bang motorcycle engine & they used a long chain with a sprocket on a straight axle. Since bike motors don't have a reverse they used an electric motor to back up. Tried to find it online several times over the years but never could. It was pretty kool & I'd still like to build one someday (if I liv to be 100 I guess)!

You could use a rear axle right off the transmission with gears on the hubs. That would solve the problem of cornering... maybe. The wheels could be on independent suspensions.
Sam, no sure I understand what you're saying...
The topic made me think of this one... rear engine and chain drive
The third picture... I just thought that was awesome.. chain drive tandem axles
Last one looks like you basically have a rear axle that the chains are mounted too.. that would allow for the speed/rotational difference around corners.....? also very cool how the brakes are on the "upper" axle and not out at the wheels
Obviously the main issue is to have a differential or it's like driving a car with a spool. There are fancy chain or belt drive trike axles, all billet stuff and big bucks.
You could build one fairly cheaply using any type of rear diff that has a rear cover. Flip it over, remove and plug the pinion, toss the ring gear and mount a sprocket to the carrier. Of course, lubrication would be an issue since you'd have to run the chain out through a couple holes in the rear cover.... fill it with grease ??? [S
So how would you drive it from the transmission end ??
I don' know if this will help but I will trie to explain how I built the rear end for my wife's trike. I started with a mazda pickup axle. it has outer axle bearings that are captured to the axle so there are no clip in the carrier. I used the axle tubes cut off of the center section and welded them to two plates that I bolted 4 bolt flange bearings to that the carrier would spin in these are spaced apart the same distance as flanges of the bearings with spacer blocks and then wraped with a band of steel with openings for the belt to run in and out of. I enclosed the spider gears with a tin cover made from a center cap from a mag wheel it just happened to be the right size and installed a grease fitting to lube it. To drive it I removed the ring gear and machined the center out of an aluminium Harley rear pulley but you could do the same with a sprocket. I hope this helps.I'm sorry I don't have pictures.
You need to check out this group, they race these cars with the solid rear axles and chain drive.
