I am half way between Seattle and Portland. I am running the mill with factory controls on front panel. All Boss machines came with vari-speed. The v-ram Boss had conventional hand crank 2-J head for speed change. The rigid ram usually had a GAST air motor which operated vari-sheave drive. Replacing the vari-sheave with frequency drive and herringbone sprocket really makes sense only for high end surface finish job shop. Hobbist usually are better off with factory hardware. This includes me. I have 12 BP Boss machines in stock but I do not perform contract machining. I am a collector and occasional seller. The primary reason for frequency drive dedicated to one machine is to utilize single phase power. This avoids the annoying noise from roto-phase running all day. Saves on power consumption as well.
