Little sprockets.....

Well time to try and make some 7T sprockets, I'm not spending a lot of time doing these to any great plan, just simple sprocket to (a) test the gearing and (b) see if the design works anyway, if all goes well, then I will spend some money on some good sprockets.


I know were not talking lots of money here, but when you have little money and a lot of free time, it makes sense to use that time to test an idea before putting money into it.


So, design printed on paper, holes drilled, sprocket rough cut with angle grinder, and then later to be smoothed with a file, well no, I stopped at the rough cut stage.....


Sprocket was welded to a nut, just large enough to slip over the stump of the motor, and a hole drilled and tapped in the side of it for a grub screw to tighten it to the key on the motor shaft.


a picture paints a thousand words, and shows what i mean by rough cut....









At this point I was going to mount the motors and size the chains, then I noticed the wheel I had removed from my trailer for the purpose, had gone missing....

Seems between it starting to rain in the afternoon for the entire day, and re-starting the thing this morning, someone has stolen the loose wheel....

As I cant have a one wheel trailer, I'm on hold while i decide to abandon or try and fit different wheels.

As the axles for the wheels were welded in, I'll have to cut them out if I change them, and I would need more wheels and to replace the stolen sprocket...

Bastards.
