Finally got the three depth turret stop figured out on my Onsrud. Also it has a switched outlet that turns on the shop vac with the router. Unfortunately that pulls too many amps and slows down the router causing the bits to dull quickly. Now I use a separate circuit for the vac and turn it on manually. BIG IMPROVEMENT. This is Jim's JAEbird II which will have ThunderBucker pickups. Since he owns a Lull I'm looking forward to seeing how they stack up against each other.
