    Thanks for the history lesson! I was considering repainting it, but I think that would take away from this particular drill and it's background. I can't find a manual for it anywhere.

    I have yet to research VFDs. First off, what size VFD would I need for a 440V two speed motor that draws 2.8A on the high speed?

    Yes, I have noticed some of the green showing through. Here are a few pics. The only thing 'missing' were some of the handles for raising lowering the head and drill surface/table. Thanks for taking...

    Thanks Huleo! It seems reasonable enough to me, but I wanted to make sure I did not tear a hole in the space-time continuum when I turned it on.
  12. Looking for more information on a drill press I purchased

    I ran across an old Solberga SE725 on Craigslist a few weeks back. The seller had picked up a dozen drills at some surplus auction and was having trouble getting rid of this one, mainly because it...
  13. Using a larger kVA transformer with a smaller kVA RPC

    Is it 'ok'/will it work if a rotary phase converter is connected to a transformer which has a larger kVA rating? ie: Could one hook up a 5kVA RPC to a 15kVA transformer so long as the load put on the...

    Ok, so what size rotary phase converter would I need? We have a 15Kva transformer made to step 480 to 240. Does the RPC have to match kva with the transformer?

    Thanks!

    What is/are the preferred method(s) of getting three phase 480V from a single phase 120/240 service? The 480 load is roughly 3A.
