Rope Swing Experiment, Challenge

In the hayday of my rustic constructions, this was one of Mom's swings.
https://www.flickr.com/photos/43836144@N04/23936573403/in/dateposted-public=

Cedar log corner posts, major bracing was attached with 1" brass rods runni=
ng through the posts & braces. Smaller bracing was cedar limbs stabbed th=
rough their attchment ponts. The "donuts" was suppose to be pulley-like, t=
o faclitate the rocking motion, on the (cross log) axle they are mounted on=
. Split log benches, between the side posts, are attached with 1" brass r=
ods, also.

It lasted about 2 years, before the joints started flexing more, becoming s=
omewhat loose, hence, I didn't trust the safety of the jointery. I eventu=
ally removed the "donuts" and just hung the swing on the cross log. For me=
, the set was still unsafe, so I disassembled it and made another, more tra=
ditional swing set.

The nylon ropes were not very good for this application.... *as was some of=
my other ideas for this construction. The thought was there, but not the=
greatest construction. If you don't try things, you'll never know if you=
can do it or if it will work out.

This was a fun project, a real hit-or-miss ordeal, rather than precise calc=
ulations for construction.

The nylon stretched and had to be adjusted, somewhat often. This was the =
least of the problems.

The whole swing set was the problem. Though the joint pins (brass rods and=
limb dowels) were tight inside their holes, the joints, themselves couldn'=
t be clamped tight, then held tight by the pins. The joints eventually bec=
ame too loose.

The donuts didn't spin or rock on the axle, they kinna stuck, because of re=
sistance, and would slip in one quick jerking motion, so the swinging was n=
ot always smooth. And each donut moved/jerked independant of the other. =
Most adults didn't swing, per se, but even a slight swinging motion would p=
roduce that jerking of the pendulum action, because the donuts "stuck".

Other than the swing, itself, those split log benches were salvaged. Some=
months ago, Jonas' son, Ian, saw them and wanted to install legs and put =
them at the camp. The half logs are heavy... I'd prefer to resaw them int=
o 2" slabs, for Ian's seating. I told him he'd have to make the legs usin=

Is that a swing? Or is this a frame for a catapult? Put a log across the
top of this thing and you can fling mom over to the next farm! That looks a
lot like a book I saw once on siege machines from awhile back.

Back then, lots of my projects were big and bulky.... too heavy It didn't take too long before I realized that style was inconvenient for almost everyone.

Yeah, it looked cool and functioned okay for a little while, but, for the long run, the whole concept had many problems.

That is very cool! I was immediately taken to a Flintstones type
setting. ;~) Lots to look at there.

If you look closely above the right side of the swing, itself, on the other=
side of the tree, you'll see a single swing... a board attached to two han=
ging chains.

All the limbs and stuff, sticking out in all directions, facilitated Mom's =
cache of pot plants. Her whole area, there, was her little plnt haven, tha=
t way. On warm days, we still go sit out there, though it's not as "pretty=
", now. Her deck is no longer there, either.

You'd think it would have been easier to just hang the swing from the 8" oa=
k limb, just above the swingset.

LOL. Yeah, at first glance, it does kinna look like a catapult.

In her younger days, Mom may have enjoyed that kind of fling. She liked roller coasters and many physical/sports activities. I can visualize her sailing over the fence and splashing down into the neighbor's pool.

The swing, itself, lasted longer, but not the Flintstone framing.

If it was because the nylon was too stretchy, dacron would work better. In
boating, nylon is preferred for mooring lines BECAUSE of the stretch; for
stuff like sheets and halyards, dacron is much better, little stretch.
Ultraviolet deteriorates both but it takes a while (years).

making mistakes is real important

i have stumbled upon things and new approaches by just trying things out
and failing but taking away a new approach that would not have occurred
to me otherwise

also in general most people are afraid to show their mistakes but it is
good to do
