Hello all,
This is what I did. A bit extreme, and not for everyone. Please don't
attempt unless you have the proper tools and skill. There's a lot that
can go wrong.
Those are [1]1.25" Kreg pocket hole screws, though any "slim" wood
screw .75 - 1.25" length should be okay. You must drill a proper size
pilot hole first, and use a "regular" screwdriver, not a power tool, to
insert the screw. Just barely snug, don't over-tighten! Careful you
don't drill through the wall. Good luck this year!

Nari, I understand your rationale. But just realize that the zip-line
is something to work around too. Just a word of caution in opting not
to put up your zip-line that your robot doesn’t hit the line during the
tournaments. Unless there is a rule about taking it down that I’m not
aware of.

This is not a direct answer. Or perhaps it is :-)
From a coaching perspective, putting the zipline up is a waste of time
- an "attractive nuisance" to use a legal phrase. If you move the
lever, you pretty much get the blue line or yellow line points. A team
member pointed this out to me per the Robot Game Updates.
Of course this adult rationality doean't fit well with some of the
kinesthetic learners on our teams, who need to physically move the
pet/truck/whatever to whereever while discussing how to motion plan the
item. Every time. For weeks.
There are kids who note that the Tsunami waves roll in the direction of
the evacuation sign, and hope to get both mission points with just one
lever push, forgetting that it will probably take a Molotov cocktail to
make that happen. The fact that the laws of physics are against them
on an ordinary Robot Field does not stop them from hoping, and praying.
For those who are not into the humor of it all, I should point out
that Molotov cocktails are not permitted under Rule 4, except possibly
in the Gulag Archipelago.
The key question is how to effectively move kids from (often incorrect)
instinct to (unsatisfying) rationality. I use humor a lot, though it
is often tempting to use those 2x4s from the Table Building Instuctions
for other purposes.
Enjoy the ziplining .. it is a great way to waste three weeks. And
give others a chance to get ahead :-)
For my teams, I am not putting that thing up until they show me some
good stuff. One should save the dessert for last.
Best,
Nari

Subject: [VADCFLL-L] Problem getting the zip line tower to stay put
Fellow coaches,
Our zip line tower keeps coming undone. The little Velcro thingies
whose name I'm blanking on right now keep detaching from each other and
the tower leans in from the tension in the zip line, even though we're
trying to keep the arm horizontal for proper tension.
I have gone through two sets of the Velcro things and tried taping the
outside to the wall with packing tape.
I'm wondering if anyone is running into the same problem and whether
you have any suggestions. Would duct tape work better? Can I try
drilling a couple of screw through the beams that are supposed to be
stuck to the wall without running the risk of having them disintegrate?
Thank you,
Haydee
