The zip ties are just holding it together whilst I stick on some hose clamps.
Fair enough, although I might just have used the QEV as the main valve. It might have been a little more reliable.
To comment on your soldering, the work around the 45 street elbows looks a little messy, other than that it's good.

First question: Are you using flux?
Second question: Have you cleaned the joint before soldering?
Third question: Did you get it hot enough.
If you answered no to any of those questions, then go and correct that, then try again.

Put a light coating of soldering flux on the inside of the fitting, (after cleaning with some steel wool pad), this will help draw in the solder. Put the heat on the middle of the fitting, or you will solder one side and melt the other out. Make sure your useing solder for plumbing, (copper), there are different kinds.
Check the wiki, there is probly tips on soldering, or links to them.

Yeah, I didn't use enough flux and the fitting oxodised while being heated.

Nice gun .....but you should solder everything together...or something????
MERGED
When I say solder things together, I ment the subassemblies not the fittings.......

This is somthing I would expect out of 5 Star General. Nice gun btw I do really like the look of it. I too would have used a QEV as your main valve just because I have no experience with pistons and I have read a lot that they are a pain in the rear to get to work properly.

Yup, this one certainly was a bitch to make work properly, its so very annoying because it would work, then it would stop working, then it would work, then stop working for no apparant reason. Fixed that problem, the washer was getting caught on the edge of the 22mm pipe inside the reducer tee. So yeah, works well now.
I cleaned up the solder joints, and gave it some wire wooling, looks the tits now..

It certainly dishes out some power, one question if i may.
At the start of the video i see text that says your ammo is lead with bb tips, when i look at the slugs in the still pic they look more like hot glue (unless the colour of lead has changed recently). Also if they were made from lead with a bb tip they would tumble in flight due to the heavier weight of the lead compared to the steel bb.
Hot glue (bb tipped) in this case would make far better (accurate) ammo, they would also have a higher velocity.
Now there is a question in there somewhere....

The outter casing is a thin layer of Cardboard, just to form the lead slugs in, and the BB tip was to concentrate the force into a small point.
Hot glue (bb tipped) in this case would make far better (accurate) ammo, they would also have a higher velocity.
But they wouldn't have the 'punch' that the 20g lead rounds have.

I would just loose the bb tips if you want to keep making the slugs out of lead, the bb's do a great job of concentrating force only if the slugs are flying true. By the look of the corrugated iron you were shooting at your rounds are hitting the target sideways, you need the ass end of the rounds to be lighter than the front.
Having said that-Whatever floats your boat!

We tried a couple even without BBs and they seemed to do the same job.
Ill see if they work
