For the VFD I went with a Teco-Westinghouse L510, $185 for the 115V single-phase input model.
A 230V single-phase model is $15 less but the cost to run that service, just in copper alone, would be greater. Since the 115V model can drive up to a 1HP motor and the 3-phase motor I'm running is 3/4HP, I decided to avoid the sheer joy of crawling around the attic on my knees
FWIW, I called Teco support with several programming questions, I was immediately transferred to an expert who got me squared away in minutes, that's good customer service.
Since none of the above is really going to happen, I'm on a quest for a more perfect, affordable drill press. After talking to a couple guys who have real jobs, working for real companies that make real things for the likes of the military, the net result distilled down to a 3-phase motor with a variable frequency drive, or VFD as it's generally known.
What in the heck does this have to do with guns? Hang in a bit, I'll connect my crazy dots in a bit.
What I'm learning is that just about everything has certain frequencies where they ring like a bell. It never occurred to me that a heavy machine like a drill press could vibrate to a degree that calls attention to itself or, more importantly, could trigger vibrations further down the food chain, as in X and Y axis instrumentation.
What I discovered once the VFD and 3-phase motor were in place is, I now could dial in motor speeds that avoid the resonant frequencies of the entire machine. I may be overstating the case but, all I really want is a silent, smooth, powerful drill chuck, not a vibratory disco dance floor
Which made me think about barrel tuners, something I know little to nothing about. One more thing to think about at 3:00 am
I miss living in the country .
That said, some of my favorite guns came from there; an unfired S&W 27-2 5" wheel gun, an unreplaceable Sig X5 9mm, and a Belgian Browning 20 ga Superposed scatter gun, saltwood yes, but not salty wood for the Browning aficionados.
Anyway, the proprietor was a disabled gentleman, wheelchair bound with a substantial speech impediment. He and I did not need special abilities to communicate; we both spoke gun. Whenever I walked into his place of business, both our faces lit up.
I spoke with his brother a couple weeks ago and learned that he'd passed. Even though we were all business, I got pretty choked up, I wanted to talk to him, one more time at least, but it was not to be. And so it is.
Don't even know why I brought this up, Grant's gun store visit made me think of it.
How much expansion do you shoot for?
