Mind if I draw some sprockets for fun?
You can use any ideas that take your fancy.

Got a note that something was waiting for me at the post office this morning!
Look what I got!

Here it is next to a 42 tooth bmx:

A little filing to give the teeth a slight leading taper and it is ready to go! Also in the package were some other items I asked him to make for a new project, keeping them a secret for the moment though! :wink:
If anyone is considering getting Barnbikes to make something, go for it! He is great to work with, his prices are good and it came so well packaged nothing could have damaged it!

Thanks Jon!

Luke.

How close is that going to be to the chainstay :? ?

:lol: I think it would end up half way through an unmodified chainstay, I will do my usual trick and get out the grinder and welder... :wink:

Beautiful chainring @LukeTheJoker
And i thought a 65T chainring was big.....

It is beautiful, but it is not my work, Barnbikes Jon is the man! 8)
The beauty of the 70 tooth is that if I wanted to every second tooth could go bye-bye and I would have the most awesome skiptooth sprocket! :mrgreen:

why not make a 2piece sprocket like modern bikes but for 1piece cranks ? a star shape that can fit many sprocket ring

I actually drew one up on saturday. My biggest concern is keeping the sprockets in line. .125" would probably not make a big deal.

I believe Porkchop actually makes one like that...

Now just have to figure out the screw sizes. Counter sink the hub and tap the ring?

I would just use standard chainring screws/bolts whatever they call them. The outer has a sleeve with a groove on it and the inner fits inside with a hex/allen head... Available in black, polished or anodized in any color you want, would look awesome with a black chainring and gold anodized bolts!

Either that or stainless acorn nuts, but they may stick out too far, look awesome though!

Cool idea but the thickness of the 2 plates are .200"

Ok, so apparently coming up with cool ideas for sprockets that actually look good on the page is way harder than I thought it would be.
Here's a couple that I did, but I'm not really that impressed with how they turned out.
If I come up with anything awesome, I'll post it.

Actually these are the ones I meant:

They tighten down to 4.4mm, so your .200 (5.06mm) will be fine.
