Would you fly this one?

Hey Jim? What's your latest wood working project? I'm looking for a
cheap table for my router, any ideas?

Go to the library, and look through Fine Woodworking magazine, and a couple
of others, and find a home brewed router table you like the looks of. The
home built ones are usually superior to any reasonably priced store bought
ones - too flimsy.

There are a couple brands of router mountings that make a more precise,
easier adjusting, and easier access setup for changing bits, that are made
for home brew tables. they are not a requirement for most setups, but they
are nice for changes and precision.

I have never made one, since I have a big ole hunk of cast iron shaper at my
fingertips. (and yes, I still have all of them- knock on wood) I have
considered it at times, since they will do some jobs better than a shaper.

Key things to look for is ease of changing setups, and ease of repeatability
for precision. The fence should be micro adjustable, with some type of
threaded rod or bolt controlling the changes. The infeed and outfeed of the
fence should be adjustable independently, if at all possible. One good
thing about that kind of setup is that you can use it as a jointer, then.
Secondary, is ease of bit changes, and third, a good sawdust collection
system. It should also have grooves for guiding miter jigs or custom made
sliding beds.

Shoot, you probably can find that kind of stuff online, now.

Jump over to the woodworking groups. Some of them are pretty active, but
believe it or not, you will find some people over there to be more
opinionated and abusive, than here! Hard to believe, huh?

My latest project is coming to a close. (I hope) I gutted my kitchen, and
built all new cabinets, tiled the counter tops and floors, and also built
raised panel doors for all of them. It has been a monster, and I will be
glad to get it done. Sanding and finishing is next. Yuck!

What's the deal w/ the counter weight? Why not have two blades and use
that dead weight to generate lift?

Believe it or not, every additional blade means a loss of efficiency. One
blade should hover and fly on less HP than two blade. That says nothing for
smoothness, and I would think that setup would be totally unacceptable, for
that one.

I have seen propellers for a model airplane that had only one blade, with
a counter weight... has it ever been made for a full scale aircraft?

At least one motor-glider uses a prop like that.

I've never heard of a non-glider using one, but it wouldn't surprise me if
at least one person has tried it. There are people who feel that a
single-bladed prop is the most efficient, because the one blade moves
through the least-disturbed air possible.

!!!!!!!!!!!!!!!!

The picture about four slides later is not bad either!

How much efficiency would be sacrificed by putting a wireframe guard
around these things? I don't mean a tight mesh that you couldn't still
get a finger into - but at least something rigid enough to keep you
from slipping in up to your waist! Damn.

Holy Crap!

Is the pilot really as close to the blades as it appears?

Common enough for at least one sailplane manufacturer with self launch, or
sustain capability engine, to use a one blade prop. When shut down, the
engine lines up the prop a certain way, and the prop and engine fold back
into the fuselage, behind the cockpit.

I don't remember that much about it, but I read about it, one time, a while
back.

Anyone remember what I am thinking about?
