A problem I have with my "old" Michael Engineering pump...a machine
purchased 20 years ago amid the Q-2 craize (which, by the way, brings up a
lot of unpleasant memories of a not-ready-for-prime-time, fly-by-night,
under-financed, company which over-sold a marginally-designed kitplane (but
that's a too long, dreary tale)...back to the problem with the pump...it
might be wonderful if we were using resin/hardener mix ratio of 45:100 parts
by volume.
As for recalibrating the moment arms for a 25:100 ratio or modifying the
pump in my shop or at the factory, my seemingly straight forward email
request for info from Michael Eng. has gone unanswered which fits the
pattern of previous postings which characterized the company as
non-responsive and un-helpful.
