Stock Sprocket, drill holes for use with Manic Mechanic Adaptor?

[MysterySandwich]

Well... pretty much as the title says -- is it possible to take a stock sprocket and drill some holes or do whatever so it could fit on a MM adaptor?

I'm sure it would be possible to drill one but getting it lined up enough to use it i'm not sure

I've done it.
Measure it real good, so you get it centered good, so it will not wobble/hop.
I'll try to get a picture of it tonight.

it's possible. just make sure you get the holes centered properly. i drilled and countersunk a steel, 30t moped sprocket to fit one.

i also modified a MM sprocket to fit a moped hub that's got 6 mounting holes cast into it.

i had to bore out the center hole of the sprocket and use some forgotten high school geometry to center all the holes but it works fine.

Ah cool thanks guys, now I have that option if it comes down to it...
Just worried, I've never done precision drilling before.
