Have you ever created a sliding pole out of cheap but strong
(stronger than aluminum anyway) 10' EMT tubing?

What fittings would you use so that you could slide & clamp
the two ten-foot steel (EMT conduit) poles together?

I think you're barking up the wrong tree. The 3/4 emt may be strong
enough, but its too heavy. The 1/2 emt will bend way quicker than the
aluminum poles. The fittings you got look really nice, but none of the
electrical fittings are designed to be loosened and re-tightened
repeatedly. The fittings are also not made with the ability to telescope.

And if he's going through pool poles that fast, it would suggest
that they are being abused. The ones I've had are nothing special
and last many years. The brushes are the problem for me. They
only last a season or two before the bristles get brittle and start to
fall out.

Also, some of the problems with the pole, ie the cracked plastic
nut, may be lessened by storing it out of the sun....

That's exactly the opposite of my experience!

My brushes seem to last forever:

It's my NETS which fall apart in a single season!

Hmmm.... it seemed logical.

First off, the floaters clearly have holes for this purpose.
Secondly, out here anyway, we have strong prevailing winds
for the summer and winter which move the floaters to one
end of the pool permanently unless they're tied down.

Only the floater in the spa stays put; but the other two
floaters will be in the same spot all day if I didn't tie
them to the middle.

As an update, I bought a screening kit to make new pool nets
out of window screen. That window screen kit came with rubber
'cord'. This black rubber cord seems to be a 'perfect' size
for the floater holes; but, of course, only time (and chlorine)
will tell the complete tale...

I had one fall apart, took me weeks to find the glass on the bottom of

Strings on thermometers, never any decay.
Don't use floating dispensers but the chlorine might be an issue.

Nope, 5-10 years from hoses, even when I step on them.

Ever try to get the recycling people to take away a plastic recycling
can that has fallen apart? Still trying.

QUESTIONS for the problem solvers:

Mine hangs from the ladder which is on the south side of the
pool so it doesn't get direct sun. It's underwater anyway, I wouldn't
expect much affect from the sun.

Q2: What strings do you use for your floaters anyway?

No floaters, but it's string. Cheap to replace.

I have no trouble with my pool pole stored outside - horizontal on a
wall with a place to hang it. This is the Mojave Desert. The plastic
knob gets some silicone lube on the threads.

Nets, brushes, etc. are under the covered patio.

I was afraid of that.

The good news is that I don't really need to telescope.
The pool is 9 feet deep, so, I just need, oh, I don't know,
9 feet plus 5 feet = 14 feet (or so) of pole.

So, it's not a requirement that it manually be adjusted
to size more than just once.

But, they 'do' have to fit together, so, that's why a
3/4" to 1/2" fitting would be perfect, if I could find one.

In the chain link fence business they use a top rail made of steel. I'm
not sure what the smallest size would be, but it comes in 20 foot
lengths. If its not too heavy, you could possibly cut a 14 foot piece of
that.

No, it wouldn't.

That junction would be tremendously weak, and would likely break the first time you used it. It is not intended to be a structural connection.

In order to have any strength at all, the smaller tube needs to telescope INSIDE the bigger tube for some distance. It needs to be a snug slip fit or it will flop around either kink the inner tube or split the outer tube.

Try telescoping the 3/4" and 1/2" together. It's too sloppy of a fit. It will never work as-is.

If you're a machinist you could turn some bushings out of brass or steel to take up the slack, but if you were a machinist you'd have thought of that solution already.

Redneck solution involves wrapping the smaller tube with electrical or duct tape to take up the slack. Drill for a cross pin to hold the pole at a predetermined length. Multiple holes in the smaller tube to make it adjustable.

You may want to look at the grey plastic electrical conduit. I don't know
of any coupling that will let it slide, but if you really have to have it
slide, drill a hole or two about a foot down and put a bolt through it to
hold them together.

I did test the gray electrical conduit at Home Depot, and it was really
light but it was too flimsy (although it may be good for an outer
sheath outside the steel EMT electrical conduit because it won't get
hot in the sun as much that way).

The threaded electrical conduit was too heavy; the gray plastic too
flimsy; the EMT conduit just right.

So that's why I settled on the EMT conduit.

As for the threaded bolt, I've already used that for repairing the
pool poles - and it is a great idea.
http://www4.picturepush.com/photo/a/...g/12866432.jpg

You can see that hex machine bolt rusted ... so I might want to
go with a stainless steel or nylon carriage style bolt, cut as flush
as possible.

BTW, do you guys have a rule of thumb on how LONG a pool pole should
be? For example, how many feet would you add for a 9' deep pool?

The hardest workout they get is lifting decaying leaves off the cover.

If I was determined to make my own, I would not try for telescoping,
too much complication. Not sure what would be good though, you want
strength but not the weight. Not really compatible qualities.

Mine has sun all day - no shade whatsoever - so I know

pool is deep, and leaves blow in all the time because of

Leslies, only when my preferred place is closed.

For brick retail, I prefer Sun Pools (Rt. 22 NJ), not a chain.

No store can even get close to the selection online.

I hadn't even noticed the dents until you said that,
simply because the bends which break eventually caused
more problems, as did the cracks in the adjusting plastic.

I suspect the dents are from being brushed against the
sharp side of the pool edge, which has an overhang of
stone. But I'm not sure.

I have no idea what telescoping tubing or pipe might cost.
Aluminum irrigation pipe is typically cut to 30 foot lengths. One man
can pick up an eight inch diameter pipe with reasonable effort. Suppose
you went with a 3" or so diameter pipe or square tube?
Is there such a thing as a telescoping mast for watercraft? Flagpole?

I like the idea of telescoping square tubes of aluminum.
They will be stronger than circular tubes & just as light.
And, the clamping mechanism will be simpler.

Googling for a source for 10 foot or longer lengths, I find
Grainger a bit pricy for the 6'foot lengths at $18:
http://www.grainger.com/Grainger/alu...ecatalog/N-cl0

At Lowes, 8 feet of aluminum 1" square tubing Item #: 215640
Model #: 11392, is also pricy at $31.33.

Yet 1/2" SCH 40 (.840 OD X .109W) 6061-T6 Aluminum Structural Pipe
is about $26.40 for a twenty foot length:

Square aluminum pipe 1/2 SCH 40 (.840 OD X .109W) 6061-T6
Aluminum Structural Pipe at that same place is $26 for 20 feet:
http://www.metalsdepot.com/catalog_cart_view.php?msg=

There is a nice weight table for various sizes he
http://www.metricmetal.com/products/sq_alumtube.htm

So, maybe the square aluminum is the best choice, since it
will withstand the corrosion better, and, it will be lighter,
and, if square, just as strong or stronger than the steel.

Pretty sure, for equal weight, round tube is stronger than square.

And now, to go full circle--- I'm pretty sure that if Danny D spent a
few bucks on a decent telescoping pole, he'd do it once, spend no time
on Usenet trying to build a better mousetrap-- and it would be the
lightest, strongest, cheapest pole [in the long run] possible.

I'm not kind to my tools. My $40 pole from 12 years ago did pool
service for 4-5 years and now knocks apples and peaches out of trees
in the summer-- and pours rock salt on my gutters in the winter.

PVC appears to be too flexible in the widths we're contemplating...

Too heavy.

Hmmm... can that be true?

Assuming the same material, round or square, I thought the four
corners on the square reinforced against the inevitable bending
forces that occur in pool cleaning better than would the round rod?

Googling, I see that an apples-to-apples comparison matters greatly,
as we don't care about compression or torsion strength, for example,
in a pool pole.

Also, the comparison, for home use, would not really be pound-for-pound
or even inch-for-inch, but dollars-per-fifteen-feet comparison, since
we're looking to compare bending strength for a cheap pole of round-steel
versus square steel (or, if the square steel is too heavy, square
aluminum).
