General Airgun Discussion / Re: Dive Tanks. Failures
« on: January 31, 2019, 07:30:10 AM »
All good Mike, thanks for the loan of them.
I have knocked my collection right back to just what I use on a regular basis.
Some of the lathe tooling has been getting replace and a general overhaul and I have fine tuned it to have zero chuck to tail stock runout due to doing quite a few rifle chamberings recently.
I been making more use of the big cenerfires again and and doing more long range shooting... even putting a bit of venison in the freezer.

I can see this ending in tears...
They will not last the distance.
Those little compressors do fine filling the 500cc bottles which takes about 5 mins and with casual use and regular oring and high pressure piston ring replacement they last ok.
Now add two more 500cc "filters" to the system and fill you nail gun which has 1000cc and you have just put three times the running time on your compressor.
The 500cc "air filters" take another 5 mins each to fill up and the 1000cc airbow cylinder will take another 10mins. Thats 20 minutes of run time per fill which is the same time it took me to top up my dive bottle from 180bar to 240bar.
You all saw how long mine lasted even with the best German synthetic compressor oil, upgraded high quality o rings and regular piston ring changes ... kaboom..

Now imagine this thing on a building site with lets say 5 nail guns working....
I hope they have a full time compressor maintainance/warranty  guy employed..

Those compressors cost less than half that on aliexpress but unless you are just filling a pcp directly  with casual use, dont even go there.
If you use a lot of air buy a Bauer compressor..

They dont last long around my place.. they are top of my hit list.. Ive watched them bullying Tui's in my trees out the front of my house while stripping my kihikatea trees of berries, so yes they also fight for food with the natives  and thats all the reason I need.
Ive dont a lot of pest control around farm sheds, airfields and hangers and they are target number one. Ive removed thousands of them from this planet and will continue to do so

Controlling larger numbers of any pest is best done with a little "pre-site prep" and a single shot from a safe distance...

Once again.. the law states it is illegal to have a loaded FIREARM in a vehicle.. no mention of airguns so totally legal practice  regardless of personal opinion. Well done Hidayat..

Great to have another member in the build. If you need anything just ask we will try to help.

Not a lot of workshop time happening for me..  I did knock up a quick brass transfer tube and cut the  counter bores in the breech and valve to seal the O rings on.

« on: August 02, 2018, 06:15:37 AM »
While the yield and tensile strength is ok the wall thickness is too thick. Material of that dia only needs 3mm walls.
Dont forget that safety factors dramatically dive with plug designs.. threading or pinning plugs will always be the weaker part of the build due to the way the pressures act in a cylinder.
At any given pressure the load on the end plugs is twice that of the load trying to split out the side of the tube.

Ulrich Aluminium  sell 31mm x 3mm, 32mm x 3mm and a 32.2 x 3.2mm in from memory 6360 T5 (Call them to confirm) and is a suitable tube.

Wakefield metals also do an imported 6061 T6  1"ID with 1/8" walls that is suitable.

Aviation suppliers can get you the 7075 T6 in that same size but its not cheap or you can get Titanium off aliexpress which is made by Snow peak in China, the second largest Titanium supplier besides India. Most of the Ti available in usa comes from China or India.

ahhh. the central north island wallaby!

But that's possibly as much my eyes deteriorating

Im convinced it is... those central north wallabies are although large, are common maize eating hares

I totally agree Akzle, I have tried LEDs in the past and find they dont have the same success rate as my trusty ol 100w 12v halogen spotty. I think in some cases the brighter white light of leds have the critters looking away or spook quicker.. I run a small gun mounted LED Ultrafire torch for close or finishing shots but all my spotting is done with the trusty old halogen now.

HSS and a bench grinder. white wheel. toolmaking is an art in itself, but if you run old gear (i know you have some new flash CNC aircraft grade stuff) it's invaluable, and there isn't much you cant form up.

I still run a lot of HSS too and make plenty of tools with it for oddball jobs etc

No you are right, not a lot of machines needed but I have a massive amount of tooling, taps dies, milling cutters, chambering tools, std and long series drill bits, center drills, countersink bits, throat cutters, hole cutters, dovetail cutters, end mill cutters, ball nose cutters, knurling tools, cut off tools, turning cutters etc etc.. they all add up and you always seem to need a size or type you don't currently have.. Id say the tooling I currently have adds up to way more than what the machines that run them arte worth.

Anyway the little pistola tube passed its 24 hour 4500psi leak down test and is now doing another 24hour low pressure leak down test at 1500psi because they are more likely to leak at low pressure than the higher pressures due to less force on the poppet valve and rubber O rings seating them tightly.
No bubbles in 6 hours so Im quietly confident.
