Keying really big bore




Here's nice job we did recently: Keying some 50" four blade bronze propellers with 5" bore. We broached 1-1/4" keyways in the props with our Mitts & Merrill keyseater. This big old beast started out life on a WWII aircraft carrier and will key just about anything we can get in the shop. We've done a lot of large couplings on it, too.




This is a job we did for another shop that wasn't able to handle it. We're seeing that more often--shops that have gotten away from custom hands-on maching in favor of CNC production type work.




We can do both. With a Milltronics CNC lathe, lots of manual machines, and a machinist who can operate them, we can do production work quickly, inexpensively and accurately, along with custom stuff that requires actually getting someone's hands dirty.




Can your prop shop boast that?
