U-Joint less dirve line

[Mechanicalbob]

After looking for a "new" type of drive line for a project, I came across a neat idea. I was at my local LHS (local hard ware store) and found some 1/4" flexible extensions. What I did to make them work was take a hex drive drill bit heated it up to remove the drill bit. With the hex part I welded it to one end of the flex drive. Where the drill bit was I drilled through the side to put in a set pin to hold on the tranny output. On the other end (Diff side) I used a 4mm socket drilled out to fit the pinion shaft Along with a set screw. I also welded the socket to the flexible extension. The cost of the flex drives was $5 the drill bit was $3 and the socket was $2. The ones I found range from 3" to 12", also there a a few shaft diameters to choose from. The thinner the diameter the more flexible they are. I would post pictures but I do not have a camera or a computer that I can upload pictures.

I keep seeing those and was wondering if it would be feasible (sp) to do that and would it flex out of line to badly under torque. for doing it let us know how it works.

thats a sweet idea....does it put any stress on the input on axle and output on tranny? i would really love to see some picks!!!!!find a camera and good comuter.lol very creative!!

great idea ! ! ! !

from what i read there is no slip on these ( male / female parts ) i wonder how they would work on the R2D while shifting the dig

for the front it sounds like a winner wish my 1:1 had flexible drivelines that would work .......................... aluma flex drive lines ? ? ? ?

That is what I had in mind was the R2D tranny. From bench testing with a drill and a vice they hold very well.
