I'm shopping for an electric brad nail gun and found only a few models
available. On many reviews I read, a commom complaint is underpower. These
nail guns all have the same design: a large electric magnet that is
energized by the trigger and pulls a hammer to drive the nail.

Does it have to be this way? Why not use an electric motor to wind up a
large spring to drive the nail, or spin up a flywheel and then use the
flywheel to drive the nail? The idea is to build up potential energy and
then release it in a hurry. You can make the nailer as powerful as any air
tool this way. The down side is the user have to wait a second or two
between each nail, but that is still better than having to get a hammer to
drive in the rest of the nail.

A compressor and air tool requires more storage space and is more cubersome
to setup. A compact solution, even if expensive, is still useful.

Saw a TV program about an electric powered (can't remember the brand) nailer
that repeatedly hammered the nails in, much like one would do with a manual
hammer. It would hammer quickly taking about a second to complete the job.
You had to hold it in position until it was finished. Possibly it never made
it to the market.

I have NEVER yet seen in my life an electric nailer of ANY size or electric
stapler that was worth a shit. Air is the only way to go, and the
inconvenience far outweigh the poor performance of electrics.

Bought a Porter Cabler 2.5" air nailer at a pawn shop the other day for $40
to do a bunch of baseboard and door casings. What a breeze! And with the
variety of lengths of nails, I have many projects to use it on.

The size and weight is going to be much greater that the present crappy
nailers. A pro is still going for the air and the speed and power and most
amateurs won't pay the price for a serious gun, if at all possible and
practical to build. .

OTOH, if you have a viable design, make on up and sell the idea to the big
companies and become rich.

I have a Passlode Impulse framing nailer that I love, and just bought a
finish nailer of the same design. They use a small gas (Mapp gas?)
cylinder and drive the nail with with a piston that is powered by an
explosion from a spark plug firing a gas charge. Check them out. I know
HD has them. I got mine from pawn shops though. Actually,I think HD
rents them too. Larry
