I've read all the responses so far and I'm surprised that nobody
mentioned using core drills to reduce HP HP and pressure requirements.
Of course, I don't know the ups and downs of it, I just came to mind.
Fantastic point! Annular cutters or core drills are great! I could
perform the entire process with less stroke, etc. The only problem is
the "plug" of material that sometimes remains in the center of the
tooling regardless of how fancy of an ejection spring or system is used.
With a core drill, the customer would also have to stop the motor after
each "stroke" to check for the plugs. With standard tooling, they can
turn the motor on at 8 AM and off at lunch, then repeat at 1 PM until
closing time, etc.
The start-up loads sometimes cause companies to pay extra so many prefer
to simply run the machines constantly during a shift if it's a
production job.
I'll have to send you a pic of a "multi-drilling machine" we put
together to drill two screw pilot holes in a block. I took a small B&D
hobby drill press and bolted a Harbor Freight 3/8" $20 hand drill on the
side. Truly inspired!
Hey... If it worked for the job, then it's perfect, right?
I have a customer who has 12 Dewalt hand drills tie strapped to a bar of
some sort. They stroke it *manually* down into their wood part to create
a line of holes. He replaces at least one drill a week.
I could sell him a device to do it, but he doesn't have the volume to
justify a larger, bigger ticket purchase for that specific application.
It's not like a 12 spindle fixed pattern head with 7" spacing could be
re-used for much else...
