One of our members who recently downloaded and read my “6 Costly Mistakes…” report, is contemplating a change from electro-mechanical drive to hydraulic:
“I am just starting to work with hydraulics and so I’m trying NOT to make mistake #8 (not getting an education in hydraulics). We are a small manufacturing company that produces honey extracting equipment, and we are looking to make our machinery quieter.
We use several linear actuators on our equipment which consist of instant reverse or gear motors and acme threaded rods. They have a lot of bearings that have a habit of making a lot … continue reading »
In a previous blog post I discussed how being engaged and caring about what you’re doing often has a cost associated with it. The odd sleepless night and premature grayness come to mind.

To this the presenter replied: “How fast is fast?” And considering fast is a relative term, it needed clarification. Indeed, when it comes to … continue reading »
