new extractor how to convert to elec

[cdanderson]

I have a new 9 frame radial extractor - hand crank.

The motor upgrade would cost $400.

Is there a simple, safe way to add a motor myself and save some money or is it more trouble than its worth ?

Pictures or diagrams would be appreciated.

Thanks
charlotte
