Re: VFD Selection

Hi Dave. I had a "chewed up" DA series extension that I reground the
od to fit some metric bearings I had. Made up a steel tube housing,
and a housing to stuff it in and it works quite well. I also made
from scratch, a DA series to go directly on a 25,000 rpm motor. That
one didn't work out due to the bearings not being "sturdy" enough.
Check out the photos page, Rick-o-matic folder. I have also
entertained the thought of using a new (import)DA extension and taper
roller bearings. Don't have time right now, getting ready for the
NAMES show 24th/25th. I have more pics at cnczone. Good luck! Rick
