08:41 PM aandrew: that offset weight must be hell on that motor shaft
08:42 PM rue_mohr: no

08:58 PM rue_mohr: maybe you can cause its forward, how did that go...
08:58 PM rue_mohr: yea, rings are ok with this
08:58 PM rue_mohr: cause there is no storage in the core
08:59 PM rue_mohr: its used to conduct
09:00 PM rue_bed2: I think its a cool converter and everyone should build one
