hi all,
i'm bought myself a little 3 pole bendini magnet motor just as a little garage project to help me learn the basics but unfortunately i put one of my magnets in round the wrong way using super glue.
can anyone advise me the best way to get it out?
i tried acetone but i think the hole is too tight for the acetone to get down there.
many thanks
zac
Heat up the aliminium with a butane torch so the hole expands. Probably the glue will go away too. Then you kan shake out the magnet or use another magnet to pull it out.

a ha, butane torch , yes i didnt think of that. thanks. i already thought of the magnet trick. i have rare earth magnets that should do the trick but i'll have to go a buy a butane torch from the local WICKES.
many thanks.

One notice: heating will unavoidable heat the magnet too and normal Neo magnets normally allowed to heat up 80°C, beyond that they gradually loose their strength. Of course this is a smaller price than making another hub...
You're welcome :)
Put a heatsink (another neodymium) on the magnet so it wont heat up as much so the magnet doesn't expand too.

ahh, now that might be tricky as i dont have another.
i feel an ebay search coming on.....
yey! all done.
bought myself a mini butane torch from WICKES. i took a good 15 minutes to prize it out but it worked!
thanks again
zac
Good to see that you didn't hold that flywheel with your fingers ;D
Good luck with your project!
