You did a great job, you should be proud of this. You REALLY nailed the "tube gun" look too.

i cant say anything .this is fantastic look and over kill performance

so the old table pool it's made wood ? and how thick is she ? 2cm maybe
and the piston what did you mean by fully rubber ? because i have problem with my piston seal face ,maybe i make one like yours
and what about the accuracy ?

and this pic i see a black line draw ,the nail in the middle, is this coincidence or accurate ?

Very nice gun what material did you make the piston off? :D

Should of read it :wink:
The piston is a solid rubber test tube stop sanded down and epoxied into a 3/4" piece of copper that slides in a nipple.

Thanks for all the comments guys :D

@far_cry: Lol no I was just marking each shot so i could tell the new ones haha. In that pic it was not a concrete nail so instead of penetrating it hit and bent the nail almost 90 degree's.

And the pool table would be about 1" thick but its not ply, its more like an MDF sort of material.

The piston is great, Its a rubber stopper like this that I sanded down and epoxied into a small piece of 3/4" copper. But because its a high density rubber and the piston isnt a perfect fit it needs a bit of pressure behind it to seal (I put my finger over the barrel when I start the pump).

Thanks again for all the comments guys

@Mitch: Sounds good mate :D

Impressive. Not exactly awed by the use of zip ties, but that's fixable.

I'd say the scope looked to be mounted uncomfortably low... how is it to actually use?

Lol pretty useless really, Its more effective to just ignore it. Zip ties will go. Thanks for the comment mate

I hope that galvanized steel is not electrical conduit, nice build!

What do you mean? You said it yourself, its galvanized steel, not electrical conduit. But thanks mate

Galv steel is occasionally used as a material for electrical conduit. It's still pretty strong of course, but not as strong as Galv steel that's intended for use under pressure.

Wow I had no idea. Well I got this from the plumbing section at my local hardware store so I am assuming it is the latter.

I'm glad the stopper is holding up to the pressure. Well done.

I'm working on a high pressure metal coax at the moment. Here is a sneak peek.

@Iwill - Lol im glad to have pleased you, thanks for the comment

@Tech - Thanks mate, I cant wait to see your QDV perform at some high pressures. What are you going to be taking it to?
