The Mid-America balancer is all aluminum and not adjustable, but fits:
- 50mm and shorter axles
- Long-can uncut, Armatures
BTW – a pointed axle looks cool and I am sure with $1mm lab equipment probably can be measured as “focusing” the magnetic field, BUT is NOT critical to actually do the balancing process. It basically allows the end touching the plastic cover (over one magnet) to have minimal friction and minimize any effect of a Not perfectly Flat axle end (e.g. from a bad cut when they cut off the drill blank).
Bottom Line – If your tool does not come with a pointed axle, with a few minutes (and patience) with a Dremel you can round or point one of your spares.
