Hello cpoc,
Maybe this will help,
If you go down to the atm and diy section of equipment and open it up there is a sticky about building your own mirrors. Might give you some idea of what's involved.
Rainwatcher also put up this link within that sticky. If you scroll down on this website you'll see a section about building your own reflector/newtonian scopes. Just have a browse around and you might find what you're looking for.

Good luck
