working on a dust cover

[Nicholas Farrey]

Simple design i started with. Cut it out with angle grinder took about 5 mins.
Bent it by hand with some vice grips and some hunks of metal the get the straight bend line.
Then used metal hanger to create my own hinge system with the three pivot points. All in all about 30 mins of work




Its the that weird blue color just cause i primed it. So it wouldn't rust and i could see the rub points i would have to fix
Made it to just slip underneath the plastic skins and is just held in place by friction.
The three parts on top are bent to it the same shape the rifle chassis is under the skin.



What it looks like closed



And this is where i am stuck now. As you can see the dust cover crashes with the part of the bolt that has been milled out to show the calibers. I am wanting a solution that involves no modification to the bolt. I am trying to make it so that i can just put on the dust cover without having to modify the gun itself in anyway.



Just stuck at this point once i figure this out or someone else has any input to get past this then i already have a plan for the springs to have it auto close when the bolt is closed.

any input is appreciated.

Pitty there are no good high res photos of the dust cover from the PSR, as I doubt they would have changed the bolts for the rifle, so they must have overcome it

i do know they use like a little bar that the bolt rides on once the cover is opened.

that also in turn helps with when the bolt is thrown back forward to not crash with the rounded corner on the dust cover when its closing again.

Wow that's pretty cool I'm keen to see how it turns out its a pretty good idea especially for the dense aussie scrub I just got back from a pig cull and my rifle got full of tea tree about 4 times so it would have been very welcome

[Nicholas Farrey]

yeah i have just been working on it off and on its kind of been put onto the back burner. but i have come up with a couple ideas i am going to try soon and see how it works

[ShadowPeo]

Only thing I have come up with is flaring the area that sits over the bolt out, and up at which point the bolt should lift it out of the way, but it would change the entire athsetic of it and make it look ugly

you could make a pice that petruded out like a little tag at the point where the bolt meets the cover so that ot contacted the bolt earler and just adjust the angle untill it lifted smoothly or add a rolled section like what retains the pin to the area directly above the bolt
