Tax included.

Secure Payments

When the cocobolo guitar neck started chattering under my $1,200 oscillating sander, the luthier’s eye twitched like a downed power line. Enter the JET JBOS-5 – this 72-pound beast eliminated 82% of vibration, rescuing the 200-hour build with curves smoother than river stones. For luthiers, sign artisans, and scroll saw heroes fighting tear-out, this isn’t a sander – it’s tranquility forged in cast iron.
