Definitely his would be a little faster than the jig I use in my one ton arbor press. I found that the jig and press gave me a firmer and truer magnet installation compared to when I was trying to pound the Alinico's in with a brass headed fret hammer using a couple of spacers and an elastic band. I used to have them bend left and right on the way into being seated in to the bottom flatwork sometimes. Never quite got the hang of the hammer technique. I am definitely a fan of bobbin jigs.
