	Hi Stu. I just received 2 x 500mm lengths of 30mm OD carbon fibre tube from AliExpress yesterday for the same application, just under NZ$40 delivered. Smaller sizes also available and the quality is superb if you're interested. I purchased the 2mm wall thickness. https://vi.aliexpress.com/item/1005006390580191.html?spm=a2g0o.order_list.order_list_main.36.76341802ZRx2Zk&gatewayAdapt=glo2vnm

	Hi Kiwi Not worked with carbon fibre before but would be good to see how it machines. Are you using both lengths? I have an old bsa s10 carbine pcp with a large suppressor On it and I want to improve looks weight and noise if possible. Cheers Stu

	Hi Stu. Yes that'll be fine, I don't have an immediate use for the second length which you can have for $20 plus courier. PM me you details and I'll work out the freight cost. Cheers

	I will have a quick measure up in the morning just to see if it will be ok and then get back to you. Thanks. Stu

	Keen to hear how you go machining it. I use a hacksaw to cut it then mill the end to length and perpendicular. It get's fine burrs from the fibres, but a fine file or sandpaper works ok to remove them. I suspect it will work out better if it was supported maybe with a wooden dowel.

	How would a person go about making a compressor for an air rifle out of carbon fibre or aluminium? and would it make a lot of difference?

	Are you talking about a compressor tank or building the the actual compressor out of it?

	OOOps sorry ( predictive text?) I meant "suppressor" as in the topic above. I was curious how to build one and if they were practical and useful.

	They are good for making supressors, as the tube is true and lightweight. They do have a sharper tone, as the wall is quite thin though. I have made a few, and have just used flat washers as baffles with hair curlers supporting a felt like material. This works well enough for lower powered guns, but I don't think its efficient on higher powered guns. I would like to try a shaped baffle insert, but you end up using a lot of material just to cut the baffle shape out of a solid bar of alu, or delrin.

	Think to your barrel may help decide. I've had 2 of Pauly5 suppressors. Both carbon fiber, both went on crossman barrels, which were rather thin so the carbon fiber was great due to weight. Definitely for the 1322 as the barrel is longer. Read an artical or watched a video on a suppressor and the baffles were at 60" I think it was, that was because it was high power and apparently that angle took a lot of pressure away from the baffle as it wasn't flat.

	Yes, I had heard someone describe that the air hits the washers, but the angle did what you say Kruz. Definitely my next project when I get some more suitable material.

	Should have grabbed the air chief. Could have mucked around with Drilling holes along end of barrel and making a suppressor that went length of barrel. Its nicely wrapped up in plastic, sealed with tape and sitting in farm tip now. (I couldn't bring myself to just throw it over the bank as it was )
