Here is my PAL wholly of polycarbonate!
Why do so transparent?
to film in slow motion combustions

how did you make the tubing for the chamber?

when do you think you could get some videos with the barrel on?

[jackssmirkingrevenge]

Very nice, looking forward to some testing videos

[Petitlu]

Video is coming! it is being downloaded on youtube

the chamber is made from a cup to carry the ball paintball

EDIT : Thank !

You could frustrate viewers by using a transparent projectile hehehe

Fantastic I love how the flame goes orange when it's exposed to atmospheric oxygen

[Petitlu]

the hole between the barrel chamber is 16mm, I increases?

[jackssmirkingrevenge]

if the hole matches the barrel diameter you'll get better performance, though performance isn't really the goal with this one.

[Petitlu]

the barrel has a diameter of 40mm, I do not want too big a hole, 16mm seems to me much to start!

interesting behavior when all combustion takes place in the chamber:

I like it!

In the future, try putting a computer fan in the chamber. I don't think we have any videos showing how they affect combustion.

I would increase the hole size to 20 - 25mm when you do tests with projectiles.

Edit, I like how the gun only weighs a little more than the projectile, judging from the recoil in the first video. Was that playmobile was posted all the way from epoxyland?

[Petitlu]

the playmobil comes from my son's room!

the fan is a good idea to try ...

*gasp* to think I would share my few remaining playmobil figures with anyone!

are u satisfied with the camera so far ?

I've had my EX-FC100 for a couple of years now, it's similar to the one Petitlu has and no complaints whatsoever, it has its limitations of course but once you accept that and work within them they are great little devices.
