an aircylinder can solve all your problems

... even if your problem is an unsatisfied partner, if copulatingmachines.com is anything to go by

[Petitlu]

you're terrible!

[jackssmirkingrevenge]

Merci, je fais de mon mieux

[Petitlu]

I'm ready to shoot this afternoon!

[pneumaticcannons]

damn man, you really do work fast lol.

[Petitlu]

thank !

Holy shit!

2 hours in the sun to try to get a shot at MIX10! and NOTHING!

I tested everything, Air BP before, otherwise, ignition cylinder, direct and son by anything ...

I withdraw the chamber, I look if the piezo walk and it works good I ever did three tests and still nothing ....

I imagine it is not a piezo rabbit poop!

I buy from a flash kodac, chocolate and canada dry!

I really balls ...

Notice the order of mixing:

When I purgeais the chamber, the smell of butane was stronger when I put this one first ...

I knew you'd mention your favourite website.
you're predictable

damn man, you really do work fast lol

yeah

When I purged the chamber, the smell of butane was stronger when I put this one first

Did you include the volume of tubing in your calculations ?
Did you purge the tubing ?

Kids read this stuff.

[Petitlu]

yes and yes!
by cons, the flexible chamber is very narrow (flexible paintball), may be ensure mixing hurts when I put the air first, when pressure equalization ...

Oh noes... troubleshooting time.

- are you sure youre getting good spark even when it is set up (meaning there are no grounding problems)?

- is your spark gap 1mm or less? With a low energy piezo this is essential.

- are you sure the disk material you are using will burst at the pressure which the ignition will generate? I found it's very possible to have the mix ignite and the disks to remain intact if too strong.

- are you sure the chamber is 100% airtight? Even a slight leak (from the burst disk for example) can be enough to throw your mix off.

[Petitlu]

I removed the chamber and the spark was done but in my opinion not to MIX10 ...

my spacing is 1 mm

I tested the disc under 40bar! all sealed, and the manometer not drop. Whenever I have purged the chamber it was unburned gas.

I tested under 50bar chamber, it is waterproof

I think it comes from the BBQ too weak to MIX10

[jackssmirkingrevenge]

my spacing is 1 mm

Can you make it smaller? I usually make it less than 0.5mm, and with a cigarette lighter piezo I can ignite up to 16-17x, so if you're getting good spark I don't think this is your problem.

Did you calculate the volumes accurately? Propane and butane have a notoriously narrow ignition range in terms of percentage concetration so the correct mix is crucial.

[Petitlu]

I can not make it smaller ...
for volumes, many with a precision manometer very accurate.
I followed your advice, 3.5% propane / butane

I still think that the problem is the ignition BBQ
I'm doing a flash ignition ...

[jackssmirkingrevenge]

can you try a lower mix, like 2x?

[Petitlu]

2x:
Air: 1.13 bar
bp: 0.6 bar
manometer reading: 0.6-1

[jackssmirkingrevenge]

Right of course.

5x?
