Cheap Recovery Wadding Trick
BrickPrice
save me a little money (I am a student). The wadding needs to be
replaced and even though it's not real expensive, it adds up. I tired
using other materials and came upon the following: Makeup Remover Cloths
made by Premiere under the name of "Take Off". I got mine at Sav-Ons but
you can also buy very large quantities even cheaper at Beauty Supply
stores for clubs. Keep them moist before using. They are a perfect
size and come in a holder. They seem to be more heat resistant than the
real stuff.

This still must cost $$$ (for HPR you may need to fill a 4-8" dia tube at
least 1-2 diameters: that's a LOT of wadding). I'd also be concerned that
whatever is in them contains alcohol!
Most of us go to a building supply store, and get house insulation, either
fiberglass or celluloce (shreaded flame retardent newspaper). Others use
expired lettuce.

I think most events have banned fiberglass, as it is not biodegradable.

It doesn't need to be, as it never leaves the rocket. It acts like a furnace
filter, blocking the hot particles and passing the gas.

Just what I need. A rocket that passes gas. :)

Crepe paper works fine, but it's not cheaper than the cellulose insulation
which is about 50 cents per cubic foot (YMMV). The insulation is just as
bio-degradable, it's chopped-up, recycled newspaper, treated with a fire
retardant.

Yeah, but crepe paper cost about a buck for 5 100 foot rolls, wont gunk up
the insides of your rocket and you wont get "blow by" nearly as often.

2. I use fiberglass insulation for most all other applications and loose
it about 20% of the time.
3. Cellulose seems like my second choice at this time.
4. Centuri used to include crepe paper as wadding and it is indeed good as
an alternative to Estes wadding.
5. I think lettuce sucks

Nothing. I use it in smaller models all the time. In larger modles (4"),
you'd need an awful lot of the stuff. I do use a single 10" square sheet in
4" models, to wrap the chute as a final protection, especially with the
dog-barf (cellulose) wadding.

Your mileage may vary. Bob is right about the furnace filter effect. But
experience around here (Sheridan and Bend, OR and Monroe, WA hp launches)
is that the retention in the rocket does not occur more 50% of the time, not
the 80% retention in the rocket that Bob reports.
The Monroe field is a dairy farm and its associated pastures, and the
landowner, actually the WA state prison system, which operates the farm,
made it real clear that they don't want pink fiberglass laying around that
their cows will eat.
Cows, we were told, are real dumb and will eat anything. Cows are also
expensive to replace if you happen to kill one by filling its gut with
fiberglass insulation. So, no fiberglass at Monroe. Its not worth the risk
of losing the landowner permission or the risk of the cost of replacing a
cow if enough glass gets away and gets eaten by a cow.
Bend is also high desert pasture ( a misnomer if this transplanted easterner
ever heard one, pastures are supposed to be green and high desert is brown
and gray) for beef cattle. Also no fiberglass.
Both products work well as wadding and the gray stuff is CHEAP.
The bottom line is that you need to use your common sense and good judgement.
If you are likely to have livestock around, (and you are likely to have
everywhere in the west on land administered by the BLM) use the biodegradable
paper/cellulose insulation. If you do use the fibergalss, clean up after
yourself if some gets away from the rocket. Don't trash a site and thereby
lose it as an available site. Sites are too hard to come by.

A great suggestion that I picked up from this news group, which no one
else seems to have mentioned, is "Bread." The last couple of times
that I've flown, I've used stale bread for chute wadding. It worked great,
and results in a quantity of toast for any livestock in the area.
Fly responsibly,

Where do you find it for this price??
I've been buying the sheets and cutting them into squares.
The cellulose insulation is OK, but it does cause a mess in the house
if it gets loose..

With mold or without? Hmm.. sulfur-smelling toast - yum! @_@

If you have some sort of retention system. At LDRS XI I helped
clean up, I came back with a couple of armfulls of fibreglass
just sitting out there on the lake bed. I did see someone
flying with an old sock tied to their shock cord last year,
flameproof wool of course

don't worry about the recovery wadding too much, i find that pieces of
paper work just fine. The rocket is only thrusting for about 5 secs
anyway, not enought timw to ignite the paper.
cheap and easy

Ordinary TP (not Estes wadding) is NOT flame proof/resistant. As such it
would be definitely forbidden at our launches here in central Illinois. Our
grass isn't as dry as in some parts of the country, but we still have problems
with grass fires. At our last launch we had several small fires, all spotted
quickly and stamped out/doused with the water we had by the pads, but enough
to keep us on our toes. We had the pads set up on concrete sidewalks so none
of the fires started under the pads. In fact most were quite some distance
from the pads and were probably due to igniters or sparks being thrown by the
exhaust from the motors. We had lots of Silverstreaks flown and none of them
started fires directly, the fires usually occured away from the pad and weren't
noticed until a minute or so after the launch. With the drought we had during
the weeks prior to that launch I shudder to think what it would have been like
it anyone had been using TP for wadding. Our club provides a bucket of the
cellulose insulation for anyone to use, so people only have to bring rockets
and motors to our launches. We've been using this method for over 3 years with
around 20 launches each year (2 scheduled per month, but some cancelled due
to weather). We use about 1 bale of the insulation each year, though if our
attendance keeps increasing as it has been I can see us using 2 bales per year
soon. At less than $3.00 per bale this seems like a very reasonable price to
keep a whole club flying for a year. Would that motors were this reasonably
priced. :-)

it environment friendly, a good recovery wadding that works well, but if it
comes out of the rocket, rabbits (or whatever animals inhabit your launch site
that seem to make it a
safari to retrieve your reload casing(s)) can come along and eat it up. Don't
laugh until you've tried it. It may not be effective in a rocket under 2.6"
diameter, but in bigger airframes, it works quite well.

Wouldn't all that sulfur make the rabbits give off really nasty smelling

tht would ignite it if anything. You're right, the paper could work. However,
you seem to lack a little bit of knowledge as to what it is tht blows off the
nose cone or payload
section, if the case may be.

Uou are lucky only because the TP was fully ejected. If bits stayed
