680/2000 gives 140kts at 15USgph.
700/2100 gives 147kts at 17USgph (equivalent to M14 7/70).

Realized by accident (duh) when I was chasing a slow leakdown, nitrogen ref
ills of the service tank are a low tech version of a supplemental air dryer
.=C2- Not sure of the cost effectiveness of regular nitrogen refills vs t
he coalescing filter solution, though.=C2-
...and my box stock 285 CJ doesn't seem to have any more issues engine star

My notes and files are buried somewhere on a thumb drive but the SS filter
housing was 1200 PSI rated, and it was drain-able, but not while under full
pressure. Media consisted of fine SS mesh and ceramic filter matrix.
Stainless "deposit" bottles are also an option for replacing the stock snot
valves. I got so busy trying to keep up with everyday (senior) life
emergencies that all my projects dropped off in a box somewhere. Hope to
pick up and re-start again.

I am planning to replace the canopy on my CJ with a Malcolm Hood, and I am looking
for best practices so that I can avoid cracking and minimize frustrations.
I have read somewhere that the fastener holes need to be larger than the fastener,
but not how much.
Do you drill pilot holes first, then final holes?
I know that I should be in a warm environment to drill, but what is the recommended
temperature range?
Do you start at the top, then work to the sides? What about front to back?
Any special drill bits?
Trimming the plexiglass ... cutoff wheel?
Any other hard won words of wisdom?
Many thanks!

I got my copy of Red Star yesterday, and I still have questions:
1. What is the situation on engines? Are more being manufactured? Will we be able
to get some?
2. How many new CJs are being built? I have heard/seen that these are really more
assembly from spares versus new construction
Thank you!

About the stainless steel desiccant filter:
I recommend that when a new filter is installed that you fly it for 6-8
hours and check the color of the desiccant. Bright orange means that it is
still dry, while grey green means that it is wet. If it is grey green you
will know that your change interval is somewhat LESS than 6-8 hours, if
bright orange it is MORE than 6-8 hours. The change interval is different
for each area depending on your humidity. Walt is correct, FL may be
considerably less than 6-8 hours while Warren's AZ change interval may in
fact only be once a year. The desiccant kits are 100% reuseable, just dry
the desiccant in a electric oven @200F overnight, wash and dry the filters
and screens and your good to go again. Most guys buy a second desiccant
kit to use while the other one is being cleaned. Bottom line is that if
you live/fly in an area of even moderate humidity and your only servicing
the desiccant filter once a year, your kidding yourself.
A new filter:
We have been testing a "final filter" to combat trash (air tank rust, grit,
ect.,) in the air system, grit is one of the two main killers of the gear
and flap valves, the other of course being moisture. The prototype final
filters were made out of old check valves and it appears from all reports
to be doing the job, but because they are aluminum and not stainless they
may, in time corrode and actually cause the problem we are trying to
prevent. To solve the problem once and for all time we are now producing a
stainless steel filter based on the check valve design, they will be
available in about 2 weeks. These filters are NOT for moisture protection
and contain only felt filter pads to contain the grit, they should require
service only at annual conditional inspection time.
Last note, several of you were waiting for new canopy rails, they are in
stock now if needed.
Best to all,
Doug
