Dia. Mag. Alternator

Z looks good enough to give it a spin ....variable speed drill start slow and gradually increase......if you notice any rubbing or bad vibration just shut it down...........be a shame to do all that work and not at least do a trial run...........easy for me to say though .......is the play (sloppyness) where the bearings seat ,or between the shafts and the bearings themselves....or is it that the mags aren't perfectly balanced on thier shafts....that last one will be tough to do ....please keep us posted as you progress ....thanx ..shylo

is the play (sloppyness) where the bearings seat ,or between the shafts and the bearings themselves?

Everything mounted to the shaft is extremely tight.  The clearance issue is where the bearing seats in the mounting plates.  The holes there are a little larger that the outside diameter of the bearing.  The bearing plates are aluminum so they are easily adjusted with my Blacksmith Hammer and a punch.

About running the thing, I don't have any problem running it like it is.  Although only the center magnet is going to spin.  I had planned on testing it with only the center magnet first, then adding the peripheral magnets to see what the difference is.  If it acts like my small prototype then adding the peripheral magnets will double the voltage.

I ordered the gears and associated parts today, and it will take a few days for them to get here.  So, in the meantime, I will finish off the small things that still need to be done, and probably spin it up to get some idea of what the output will be like.

Hey Z so where the bearings insert ,..they're not tapered fit , so as compressed they tighten?.......you could try wrapping the outer dia. of the bearing with cellophane,...one layer at a time ...cone shaped ...so as it goes in gets tighter and tighter.....then just remove excess .....your bearing plates should keep it tight .....after awhile though due to friction the cellophane will break down.....maybe not worth trying ,but just trying to help.....it's up to you.......shylo

Its a sealed, press fit bearing...

You're suggesting that I fix it with tape?  Please...

This is industrial quality...

I fix it with my Blacksmithing skills...

Z not trying to be discouraging but,...using a hammer and a punch to get rid of the 2mil slack in the bearing seat is not going to work ...............it will never be centered let alone balanced.......with the cellophane ....if its not perfect ..easy to go back and try again.....once you punch it ...that dimples' there to stay..........shylo
