Was watching Ted's hold over and he had a pard scope which he had a 3d printed part that acted as a shade but more importantly to me had a little tab
Which rotated the ao with the shade.
Is there anyone who could print me one for my hawk scope.
I find front ao a pain to adjust while on target and think it would be a huge benifit to have the tab to aid rotation.

I could do that. Would need to know some measurements tho.

Heres the measurements Ive gotten.
Is it enough to work with.
They are as exact as I could get them, I should be able to sand out any mismeasurements by me.
Heres dimension for anyone who wants them.

your scope is way more complicated than the sample one in the photo that you want to copy.  I can probably do a straight tube with the tab you want and a thread so you can attach it with some grub screws to the outside of the scope. how long are you wanting the tube? my printer is limited to around  160mm

47mm would do. I'm more after the tab than the shade. Use it night slot too.
Whats the possibility of printing three blocks separate that I could sand down to fit between the ridges and I'll run the locking screws through them to the scope to help equalise the pressure exerted when I turn it. ( if that makes sence)

Actually that sounds like a hassel,
If you want to print me up the ring with tab and locking screws. That would be awsome and I'd appresiate it.
When it gets here I'll buy some plastic make wedges to fit between ridges, and then glue them into the inside of the ring in situ and that should work awsome and be a Taylor fit.

OK final design, sorry.
Lets go for just the tab.
If could print up a ring with tab @ 55.20mm inner circumference and a width of 17mm, locking screws
That would be awsome. Me and sand paper will fine tune the inner ring to ngsnug fit. I'll sort out gluing in some indevidualy made pieces to sit between ridges and glue them in and sand the whole thing to size of ring.
Leave design and thickness of tab and ring to you. 3mm be max thickness or ring before it touches cylinder.
That work for you?

Im off work for a few weeks, recovering form reconstructive surgery on my hand. Ill have a play with the printer and see what i can come up with. might be a little while as im right handed and its my right hand they cut up lol...finding out the hard way how difficult things are using one hand for everything ha ha

I hope your hand comes out OK.
Just as you do Nunga, if you can with a crook hand all good if not sweet as.

Not something I could do without popping a few brain cells.

Sweet let me know when it's done.
Let me know the price etc. Won't be able to pay for it till half way through next week as work been me around but I start tomorrow so should have a part wage through by then.
30 stitches that's a heap to have!
How big a cut did they make?

they did a zigzag cut from the top of the middle finger down to the wrist

So how much use of your hand do you have? That sounds like you won't have middle finger use, or be able to fold the palm of your hand. In fact I'd imagine only your thumb won't affect cut muscles

Hey Nunga you seem to be up on it with air gun building. I'm currently considering the idea of changing the the whole valve set up in the 1322 to a steel body (not piston). This would have to be machined of course.
My theory behind this is if I go to a steel body for the valve set up, along with all the other alterations you can do to increase volume and flow, I can actually have much thinner walls than ally hence increasing the amount of air in can compress into the valve.
So under the assumption your more into your metal work than me, is it feasible idea? Could the right metal decrease the wall thickness by a large enough margin ( I know from diving that the walls on ally tanks are way thicker than steel and steel tanks hold more air) if so, what would you recommend as a metal for this? I'm thinking a low corsive metal as if I use a anti rust primer I think I'll have issues with seals reacting.though I could coat it with moly on out side and the pelgun oil should keep the inside sweet.
As I say, just an idea at the moment.
Does it sound feasible?

yeah that could work, you might want to have a look at gas struts they have a thin steel wall, not sure on the size you are looking at but a gas strut and see if that might fit? they are designed to take very high pressures

Sweet idea. Cheers.
Ill do some research in that direction.

Date Posted: 03 Mar 2023 at 4:29pm
and i mean using the body of the strut rather than machining up something from scratch

I realise that. Still have to have a certain amount of machine work and bronzing done to it as they need a wall between the compressed air and channel that the valve sits in to release it into the chamber.
Though Im thinking once the divider wall is in, it would allow the channel that air flows from compressed air to barrel to be made as insert and slid into the end of the tube then wielded/bronzed shut. That in itself would make make customising the channels a very easy affair. At the moment the option for getting rid of the right angle turn is a dremel through where the brass port that goes between cylinder and barrel is. It's quite limiting on how much refinement you can do and pretty awkward from the looks of it. Probly wouldn't hurt to put a flat top piston in it too, so as to eleviate the need for a angled wall between compression chamber and piston.
As I say just tossing around an idea, so if you or anyone else has any ideas fire away with them. Even if they seem impractical... Could throw me into a new tangent that comes up with a better system.

Im doing the final print now. Im using ABS in the colour black. PM me your address and ill get it sent to you tomorrow, we will worry about payment and all that other stuff later when we know the item works like it should.

P.S its not going to cost much as ive used around 50c worth of plastic so far.
