working perendev magnet motor

Body

Hi all
 Here is youtube video of someome who seems to have built a working perendev motor....he changed the size of magnets to be 3/4"  log instead of 1" size, also used grade 42 magnets instead of grade,, and also changed the angle of the magnets too to  50 degrees instead 25 degrees...anyways looks to me he got it to work pretty good - kind of touchy for it to go,  but got it to spin by itself on just magnets...rotor looks bit wobbly takes a few tries to get it going too which to me makes me think this is legitimate....
 eventually he says it does wear down, but does 
sustain itself so that is good...Maybe with better precision to built, and grade 52 magnets it would work better maybe grade 42 is one reason it does work good....anyways  could be a project for some of you out there its just MDF board, wood, magnets and aluminum shaft and fittings....
