If you can shoot a sinker over a 100 foot tree with a slingshot, I think you
get to marry Penelope :)
Be careful which direction you launch that sinker. The line can and does brak,
and it really travels far if it doesn't have to drag the fishinhg line along
behind it. A 1 ounce sinker falling from height could really injure someone...

you have used a tennis ball gun you don't know how easy and accurate you can be
putting lines over branches, inside a tower etc etc. Slingshots are like using
a TS520 vs the tennis ball gun being like a K3. They both get the job done. 73

Topband Message-ID: Content-Type: text/plain; charset="iso-8859-1"A
disadvantage of using a fishing reel to store the line is that there is no easy
way to limit the maximum travel of the projectile. Thus the line can end up in
a tree beyond the targeted one, or in any other undesired place. A better
approach is to estimate the distance to the target and lay out that much line
in a back and forth (multiple Ss) pattern on a plastic tarpaulin. I use a 12' x
20' tarpaulin, folded to quarter size to present a 6' x 10' surface. The
tarpaulin offers the line a friction-free surface. Line that is not laid out is
stored on a 9" diameter kite flyer's hoop spool. After a shot is made and the
laid-out line is in the air, the hoop spool jumps up, a turn or two of
additional line is dispatched, and the weight of the spool and stored line
gently brakes the projectile to limit its travel. I prefer a compound bow and
weighted arrow, for the considerable length-to-mass ratio of an arrow
facilitates its passage through leaves and twigs whereas a lead weight is
likely to ricochet wildly after striking any interfering object. 73, Charles,

charset=utf-8Hi Pete and all,First of all, use an egg sinker, (1 oz. or 1.5
oz.) with the hole through the long axis. Get a small length of insulation from
hookup wire. Thread the fishing line, (6#, 8#, 10#) through the "spaghetti"
insulation, which is used to keep the edge of the hole in the sinker from
cutting the line. The reason for the egg sinker is symmetry, many other types
of sinkers tumble and all the energy is lost in the tumble.You didn't forget to
push the button for free spooling, before you let fly, right?
Also, most slingshots use tan surgical tubing, which loses elasticity in less
than two years. Find the replacement tubing that is black, it will last much
longer, but requires a "heftier" pull, and it will go farther.The slingshot mus
be of the "wrist rocket" type with the wrist brace. Then I just bent a metal
coat hanger to attach to the brace. On another slingshot, I attached the reel
to the side of the brace using stainless hose clamps with a wood dowel to take
up space in the hose clamp.I've gotten as high as 75', not the 100' that some
claim, but usually only 50' or so. Still takes practice and sometimes lots of
tries.I'm still planning on a pneumatic launcher one of these days.73, Gerry,

sebdesn Message-ID: Content-Type: text/plain; charset=us-asciiI agree
slingshots are very difficult to get accuracy with because of how you have to
hold the weight AND they often lack power at steep angles or heights over 60
ft. But I don't know about using such an elaborate device when a decent bow and
arrow is so simple and effective. And you don't have to be Robin Hood for
accuracy as you have enough launch power to get high enough over an intended
branch wihtout hav
ing to be pinpoint accurate.. That said I have had times where i did need to
get in between a narrow crotch in a upper area and it's wasn't hard to do it
with an arrow which is slender.Sent from my iPadOn Oct 14, 2010, at 11:09, bob

charset=us-asciiYes but with a little practice and a keen eye you can manually
pull on the launched fishing line to prevent it from overshooting the target or
worse, go wild. HOWEVER, be careful it doesn't arc backward and into a downward
path where you are standing (did that , done that AND survived it -- thanks to
quick legs)Sent from my iPadOn Oct 14, 2010, at 16:23, Charles Moizeau wrote:>

charset="iso-8859-1"I made the original TX3A antenna with two fiber poles each
9 meter high.Due to the tension in the diagonal wires it was not easy to get
the antennaup easy.I have the po
ssibility to put up a 35 meter horizontal wire between my towerand the house,
about 6,5 meter high.With the same total length of wire I made two rectangular
loops instead ofthe triangels. (both 5 x 11 m, 1.5 m high)EZNEC shows the same
diagrams. Resistor should be somewhat lower in value(900 Ohms). However,
putting the antenna up was much easier.I must conclude that this antenna
outperforms my K9AY loops. It comes closertomy 160m beverage (on 160
meter)73,Kees ,
