My gun needs to be lighter Need material info

[archie370]

Hey guys ive made my functional part of my gun now i need to make it lighter ... any suggestions

i have copper tube for barrel, im thinking stainless and smaller than 1/4 '

i have galvanized steel chamber which holds are, it is to small and to heavy for what i want, also need input...

and fittings what are the strongest and lightest fitting for the job ?


one more question, where can i get high pressure hose for air ... ?

Carbon fibre all the way

What pressure are you running at? Reinforced soda bottles could be an option... http://www.spudfiles.com/forums/air-tan ... 23098.html

You can get high pressure hose at McmasterCarr.com

Your gun can be lighter

Aluminium 5754 alloy.

Get some muscles, try shooting a 12lb rifle off the shoulder accurately, then you'll stop complaining.

I don't know why my mate needs a bull barrel Tikka in .223 when he doesn't shoot past 250m. And a 6-18x56mm scope is way too big.

I'm liking they the aluminum idea... And as for the hose i will look into it thankyou ... Don't post stupid shit

Really, how much does it weigh? No estimates, weigh it.

[archie370]

5kg roughly ... btw i didn't need to because i listed the materials i used and i need more efficient materials in terms of weight ....

make the stock out of Aerogel

what pressure you running it at? under 150psi get high pressure pvc

[archie370]

Na buddy its all metal ... i dont want to use pvc because i made a spud launcher before and i droped it and it crack all through... so i want to avoid using pvc as much as possible ... may i ask what is aerogel ... (btw im running it at 120psi until i make a fridge compressor to a higher psi level

[archie370]

ok i looked up aerogel ... alright lets try and be realistic ... where the hell am i going to get that haha ... im just thinking about changing the copper barrel for something that is a little bit stronger and not really heavy .... and also an air supply tank which is sort of light that i can attach to my rifle .

[jackssmirkingrevenge]

I find it extremely hard to believe that this weighs 5 kg.



The above weighs 5kg empty.

This is perfectly normal weight for a shoulder fired launcher, rather than make it lighter I think you should be focusing on making it more comfortable to hold.

[archie370]

Stock ... plastic handle plastic , grip plastic ...

btw my bottom airtank is made out of galvanised steel ... so it is heavy ... heavy fittings ... and where my pilot valve is there are a few fittings that are heavy ... so yeah i would say it is 5 kg

The great thing about making spudguns is that it encourages a scientific approach. Here's something you can try at home, take a plastic bucket and put around 4 and a half litres of water in it, then compare the weight of that to your launcher
