Don't mind the clutter.... I always forget to straighten up a little before I take a pic or two


What's the point?   Cleanup is "wasted effort" and so: over-rated . . . .

Besides, as soon as the pics are taken, it's back to the "goat explosion"  anyway.

Looking good Bob.

 cheers  and Happy Holidaze . . . .

No pics today, but played in the shop most of the day.  Made some brackets, but then figured out that I need new rubber grommets for the water tank mounts, and that will actually change the top mount. Grommets show up Wednesday at Graingers.

Thinking about the parachute tube... did a little ciphering
Old tube- 5 inch x .063 x 26 = 484.3 ci

New tube 5.562 x .109 x 26 = 583.17 ci 
or
New tube 5.562 x .109 x 25 = 560.7 ci

So I pulled the chute out of the box, and packed it in the new tube after temp plugging the end... it packed in 24 inches and had a little room to spare... that math ended with 538 cubic inches.  Lots of room  in the tube so I guess there will be plenty of room to store duct tape if I need to.  grin

In life you can never have too much duct tape - there is always something.

In the UK there is a popular brand at DIY stores called Duck Tape and that seems to have become eponymous here. Interestingly I have neither seen a duck using said tape nor indeed repaired by it.

Recently the Gorilla brand (US I think) has become popular but I think trying to pull that off a large primates fur could go wrong quite quickly.

Seriously though - thank you Stainless for the tube volume calculations. That helps put the tube requirments in perspective for me.

I may be using incorrect terms but the bridle line (that attaches to the vehicle) will presumably lie along the bottom of the tube and the chute packed on top of it filling the tube from the rear - is there any reason why a tapered channel at the bottom of the tube is a bad idea for that line or just simply unnecessary?

LM There are two systems one has it's pilot chute in another 3" tube with a spring or cyl. launcher or a pilot chute that packs in the same tube.

When I used a pilot chute that had a spring that attached to it I tied m y chute tether to the frame and it flew inside the tube

I now use a system that has a spring that is inside of a 3" alum tube for a small non ridged pilot chute and I use two different size chutes and pilots and two different length tethers 60' launched first and 45' second.  I can swap tubes so the big one is first at El mirage and the small is first on the long tether at b'ville.

LM, the tether could  lay in a channel, but it would have to be a very smooth channel transition... We have always had it just laying on the bottom, all the others folded on top of it, the chute folded in and a spring loaded pilot.  If you don't have enough tube, it gets really hard to pack the chute and tether into the tube and get the pilot in there as well.  Before you pick a tube, pick a pilot... Then talk to the chute manufacturer to understand how much volume you need for your chute. Diest did all that for us 40 years ago... then the chute grew, and pilots grew and it got hard to pack....  That is why Stan suggested you can't have too much room in the chute tube.
Our liner had chute tubes that were larger in the front than the rear... thought about the same type for this car but that is just one more thing to build. 
Incidentally, I found 5 inch schedule 5 304 Stainless at Pittsburgh Steel Products, they have a $150 minimum, but they had a 7 ft drop, so I now have some extra tube coming...  Yes I spent more than I wanted but I will have plenty of extra for the new liner, and maybe some for someone else... I have enough for 3.

LM... there are no hijacks of build threads... there is just discussion that might wander as questions and answers arrive...  rolleyes
You will see this in all the builds on this site... and one thing leads to another.... although my favorite distractions head toward food and beer.... which reminds me... if anyone ends on the big island Hawaii, Big Island Brewhaus in Waimea has the best beer on the island.... Yes, better than Kona.... drank my last bottle (with friends) of Black Whole... a barrel aged stout... thick and rich... yummmmm
See  cool  cheers
