Just thought that I need a alu frame for a gun, now it turned to guns and at least three frames, or four will be made.

One side done.

Mocking the part on Badger just to see if the overall dimensions are sound.
Not ment for this rifle but I think it could end up on it.

Interesting! I bet that made a bunch of chips.
Is it designed for ar furniture?
Dave
-
nice !!!!!!! lot of material removal.

Dave
Yes and no, only ar grip is used, I hate the imperial thread on the buffer tube systems. And to be honest, all the buffer tube furniture looks the same.
Some 35-50L of chips from two frames.
Marko
-
nice !!!!!!! lot of material removal.
Thanks,
A lot, and alot of time consuming to mill the contours with ball endmill. Roughing amd finishing about 4h per side. I need to optimize the code some if I'm making more of them.
Marko
-
That looks great... 8)
Watching to see what you have in mind for the finishing touches...
Jesse

Thanks,
Media blasting and cerakote or anodizing.
Marko

Is the top channeled for a tube? If so, what size?
Lots of possibilities with that frame….
Dave
-
Nice!
pics as they progress please

Top is still blank, they will be machined one for tube and one for my Anschutz 22LR when time permitting.
Marko

The picture service that I use to post is down, need to find something else to post pictures.
Frame is semi done, I inlet one B class frame that have machining defects for the Badger to test out the frame and components.
I'll post some pictures when the service is ok again or I'll find a better free photo service / host.
Any suggestions on that?
Marko
-
flikr.. its free with a yahoo email account , which is free also.
-
Or do like my lazy self does and just add as attachment here.
Dave
-
Do they need to be certain size? My pictures are 4-12mb
And how does it work, have never thought that one can attach pictures directly.
Marko
-
Lets try this service.

Furniture on loan from one Tikka frame.
Marko
-
4-12 may be a little big. I do all mine from my phone and it asks what size I want to use. I just pick from the options. My pictures are already on my phone so…
I can make file size smaller too by taking a picture farther away then cropping it. That’s the way I used to do it.
Dave
You posted while I was typing
My goodness Marko! That thing looks awesome!
-
very cool.. im trying to figure out how you made the buttstock.. I Know the design is 2 piece , or maybe its 3 piece ? still havent figure it out\.. looks like the stem section ( 27mm round ) is oxidized.. yet , the back end is not.. leads me to think its 2 well blended pieces.
-
Thanks guys,
Yea it's two parts, 30mm round with dovetail ish fitting secured with a center bolt.
Just about seamless fitting, you'll see it if you know it's two separate parts.

Stock without the Tikka stuff.
Marko
-
that looks stunning .. Love raw machined aluminum when its well executed/
-
Thank Rob,
Made a bag rider on the stock for bench rest shooting. Get a better tracking of the rifle through out the shot.

Marko

Sweet! 8)
Jesse

Thanks,
Well 7075 is not the most forgiving when anodizing and wanting to color it.
So black is this time something like Fifty Shades of Gunmetal.
(https://i.ibb.co/pzxNfKF/4-DA37-F8-D-1425-44-D3-9-F82-60-D5-C8-ABE4-BF.jpg) (https://ibb.co/wWR8SQm)
Can't win every time, bath heated up too much and I forgot the part for too long in the acid. One of the alu wires was already cut from being too long in.
So not enough current and oxide layer was too small.
But not so bad I kind of like it.
Marko
-
looks great !
-
Maybe not what you intended; but I personally think it looks better with that gunmetal finish-if it came out perfectly black, it'd be monotone-now it just pops between the action and grips...
Me likey! :D
Jesse
-
Wow! Looks really good. I was wondering why not 6061. Is it a strength issue or milling issue?
-
I really like the color you got there! On purpose or accidental, it really has a unique coolness to it.
And thanks for sharing it with us.
Dave

Thanks guys for your kind words.
7075 T6 is the go to material on what I usually make and that is what I have in stock. Customer work is mostly done out of this and it's just about the toughest alloy readily available so why not use it on gun parts too.
Marko
-
One more picture with better lighting

Looks better in natural light, I actually like the color now that I saw it outside.
Marko
-
Well it looked real nice in your first picture, but in natural light it's awesome!!! Congrats and keep up your cool work Marko :D.
BTW, that alu piece underneath the rear stock, is it a folding handle for BR/ prone shooting?
Francois
-
Thanks,
Well actually its a rear bag rider for bench and prone shooting.
Marko

Finally got back to finishing this build. Making butt plates so I can return the tikka stuff back to its frame.

Fits ok, now just need anodizing and colour.
Marko
-
All anodized and assembled, sorry for the mess in the background.

Turned alright and color match the rest of the rifle, despite material being 6082t6
Marko

All anodized and assembled,
Very nice complement to the build!
sorry for the mess in the background.
Quite familiar with this kind of environnement! ;D

Cheers!
-
Excellent stuff Marko. Glad to see you got some time to mess with this. Beautiful work.
Dave
-
Thanks guys!
Have been too involved in one project lately and there is much snow here. So not so much thinking about airguns. Had to anodize some other stuff so did these the same time.
A lot of plans for new stuff but have to see when there is time to machine.
Marko
-
And speaking about the new stuff, a little teaser of a new frame for the savage 45.
Want to get away from the tube guns and more stiffer upper.
(https://i.ibb.co/M7TFxwb/B7-D04602-4294-411-B-B563-D2-C2305-BD088.jpg) (https://ibb.co/yqTHcvD)
So all machined from 7075 T6 billet, picatiny rail and breach.
Marko
-
awesome marko.. question , what kind of probe or edge finder are you using ?
-
Thanks Rob,
I use Haimer 3D taster. Bit expensive but well worth the money. Once it's calibrated you can measure within 0.01mm at any direction. Good enough for any work I do.
Marko
-
thanks for the info ,. yes those are pricey , one of these days
-
As always, appreciate you sharing your work here!
Dave
-
Thanks Dave,
This is kind a hybrid project, fitting savage .457 upper on the old 20mm frame.
Had the barrel with and adapter on the frame some time ago and it was interesting.

Upper block ready.

Fits ok, now need to make some modifications to the barrel. Going to have locking lugs on the barrel and bolt.
Marko
-
very nice machine work.. especially the hollowing of the loading area.
-
Thanks Rob,
Got to test the rifle and shoots ok, 134mm 10 shot group at 200m from bipod and no back rest.
(https://i.ibb.co/vZ3Pgmy/530-D2775-7-FB5-420-F-B54-A-722-E4-F46-C053.jpg) (https://ibb.co/D59Cskc)
384gr soft point goes 276m/s at 220bar and 304m/s at 300bar so I'm ok with that.
Need to do something about the recoil, slightly too much bounce from the hammer.
Marko
-
Fantastic stuff! The craftsmanship looks outstanding as usual. That is a beast for sure but also looks cool.
Dave
-
Thanks Dave,
Finally got some time to do recoil management, and a barrel band.
(https://img.aijaa.com/m/00270/15143329.jpg) (https://aijaa.com/0P9wi5)
Made the rifle much pleasant to shoot. Also made a hammer spring catch so it wont bounce as much.
Marko
-
thats some serious power. whats the weight of the hammer ? (im assuming this is a spool valve or balanced conventional
-
Thanks Rob,
Hammer is around 80g
Balanced valve, just a bit on the large side.
Marko
-
Something new in the works.
(https://img.aijaa.com/m/00509/15151226.jpg) (https://aijaa.com/RHSjdK)
Just a teaser...
Marko
-
some kind of clamshell bullpup action ?
-
Well not exactly, just my take on the L2 frame.
Didn't like the low scope rail and have a bad neck. So need risers and medium rings.
Now can use just rings without the risers.
(https://img.aijaa.com/m/00803/15152965.jpg) (https://aijaa.com/2HCu0q)
Also adapted a Tikka front guard for longer barrel use.
Oh yeah trigger group is a 3D printed prototype for testing different trigger geometry to get a lighter trigger on higher plenum pressure.
Marko
-
awesome, looks factory
-
Thanks Rob,
Made a new trigger blade out of carbon, turned out ok.
(https://img.aijaa.com/m/00613/15155384.jpg) (https://aijaa.com/LzQXf4)
Have some other changes to the gun too.
(https://img.aijaa.com/m/00690/15155382.jpg) (https://aijaa.com/9kmxh3)
Returned the original rear to the leshiy 2 and needed something for this one.
So made some parts.
Valve is slightly modified, without restriction that the .22 leshy valves have. It's making 101J at 180bar now.
Marko

I like it , Good machine work is always a pleasure to see.
