Keep the updates and testing coming.

There are times when adding weight increases energy but it is not often.

yup, even if nobody gives a fawkes I'll keep posting (so I can keep track of what I did and when).

it did on the stock plastic piston (0.2J iirc) but that's about it.
Also, took my time to "properly" measure the Maple Leaf head.
Nozzle is 7mm ID, chokes down to 4.8ish mm for the last 7/8mm at the muzzle end and it's a clear defined step, not a gradual taper, the piston side taper is 2mm deep and goes from 7mm to almost 10mm on the outside.
The current airbrake protrudes in the actual nozzle (past the taper) by just 8 millimetres, no wonder it doesn't do shit 😄 I'll knock up a quick CAD drawing tomorrow morning for Pavol so he can come up with something, in the meantime I applied another layer of heatshrink, now the brake fits snug in the nozzle (can still move freely but there is no side to side play)..

New spring will be here tomorrow morning, will update on the new energy levels.

It's slowly coming together, a few rookie mistakes could have been avoided but eh, everything is a learning curve 😄


EDIT:
Here's a quick sketch of my cylinder head
Measures in millimetres (sod off you imperial plebs)

M100 in.
0.94J on 0.2s
1.15J on 0.3s
1.25J on 0.4s
I'll leave it as it is, the spring is brand new and it'll lose some strength over time.

Noticed some inconsistencies with the hop, it could be because the silicone decepticon is brand spanking new, just to be sure I'll put the MR hop in (it has some 500/1000 rounds put through) and check again on Saturday.

Also, for a very brief moment I accidentally got the airbrake to work:
I had it wrapped in PTFE and heat shrink, during testing earlier the gun suddenly became whisper quiet and lost 0.1J, so I took the cylinder apart to see what was up.
Well, the heat shrink got stuck in the nozzle and the airbrake was actually plugging it, holy shit it was quiet!
I have removed the heat shrink and ptfe, the only thing left to do now is to wait for the new custom airbrake to be made and posted.
I reckon that once the spring wears in + functional airbrake the gun will be bang on 0.99J on 0.4s, at that point I can consider the build finished 🙂

The SCW dude just sent me this picture.

It's silly but it should work :D (should be here in 10 days or so)

That's insane, I'm really curious to see how it is

I honestly don't know what to say about this.
It kinda looks like a weird dremel bit I guess- the airbrake looks like the part that fits inside a dremel.

This is my rifle...
There are many like it...
But this one is by far the worst...

Now that I look closer, it seems to be a "regular" airbrake (but 24mm long instead of 15) with a sleeve on.
And yes it looks like a weird dremel bit :D

Doesn't matter though, as long as it does the job, I'm happy with it :)
