I don't believe the thickness of the 12" steel rotor disks offered is listed on the alternator parts available. I am interested in possibly purchasing 2 and also wondered if any other sizes could be ordered and if so without any holes pre-drilled ? Thank you for your reply.  Dave B.

Hi Dave!

The magnet rotor disks are 1/4 inch thick steel. They are CAD-cut, including the holes,  so we'd have to do a custom run for you to make them with no holes. Email us directly for a quote. You might also consider having a local metal shop cut them for you, it might be cheaper since it would be simple and they could do it with a simple circle-cutting jig on a plasma cutter.

you can get 1/4" thick disks here with no holes.

Thank you for the information. I may use 3/4" thick magnets and figure I better go with 1/2" steel especially if I go with greater than 12" diameter besides. I've been spinning a 12' 3 blade single phase with laminants pre-heating water and plan to go with a dual rotor and probably an 18' 3 blade. This should be a better match for pre-heating water as the 12' has been more of an experiment to get the bugs out and test the application. The 85' tilt tower (shown) was more of a project than the alternator. Thanks again,  Dave B.
