We have begun to spec some yellow zinc plate on some mild steel components.
We have had a few batches of parts looking less yellow than others, and there was some report of some "white corrosion" from our finished inventory recently.
Looking at what I should be expecting from the...

I've got a 1/4-20 fastener into a .188 thick wall in square tubing.
I normally like to run with thread depth = diameter x 1 but in this case, there's nothing much I can do. I have 6 fasteners total holding on a stout trailer fender on an equipment trailer I'm designing.

OK, have a pretty simple hydraulic system. I would...

I'm making some modifications to an existing mast/boom design.
We want to lower the pivot of the mast so that in the retracted or stowed position, the overall height is closer to the ground. I have accomplished this by lowering the pivot about a foot, give or take...

Long time lurker here, first time poster.
I've spent many years in silicon valley working as a design engineer on process/testing equipment for semiconductor industry.
Recent change in career (that I love) has me dusting cobwebs off parts of my brain that I haven't used in a few...
