HI Masterlink,
Thanks for the offer....However, my current sprockets already come pre drilled for the standard ISO 6 bolt disc hub mounts (they are also drilled for the HD 8 MM 9 bolt mounts and the next batch will also be drilled to accept the standard 9 hole 6 MM pattern.... Soon all 3 mounting patterns will be on each sprocket).
For many people, disc mounting works fine but for some the sprocket (being further out from the spokes than the normal 9 hole mounting system would have placed the sprocket) may interfere with the rear frame stays or some cases the chainline will be too extreme (again this only affects some frame and wheel combos).
To see if it may affect your combo, you can cut a piece of cardboard about 1/4 inch thick and 6 inches in diameter (the approximate size of a 36T sprocket) and hold it against where the disc would mount and see if the cardboard "sprocket" hits anything....The smaller the sprocket the less likely the sprocket will hit the rear stays....
If you find problems, the remedy is to re-dish the wheel and/or re-space the wheel by moving the adjusting cones and using spacers as needed. Re-dishing is not an option with "mag" type wheels since they have no spokes to alter the wheel "dish".
While the above will solve the problems for most people, they are not necessarily the optimal solution....re-dishing weakens the wheel and re-spacing (and to a certain extent re-dishing) may induce slightly "weird" feel to the bike since the rear wheel will be out of line from the front wheel....this is not necessarily bad.....just different.....
I am currently working on an adapter to reposition the sprocket closer to the spokes using the 6 hole disc mount and 9 hole sprocket (with enlarged center hole)....version 2 of this adapter will move the sprocket AND (hopefully) allow the end user the option to still use the disc brake itself...(I'll post pics in the vendors section).

PS - While "overkill" I have toyed with the idea of making an adapter so that a person can run 2 discs for braking on each wheel (of course you would have to purchase another disc caliper and probably run a dual pull lever to actuate them)...Just a thought at this time tho....
