  • Some Tikka T3 short action AICS/Viperskin chassis finished!

    I had some material arrive last week and made a start on some chassis yesterday. I'm making 10 in this batch, I did 8 right hand and 2 left hand. Below is the first operation cutting the outside shape from a piece of 40mm 6061 plate:

















    I'll post up some more photos as I get further along with the process.

    P.S. That's a Howa one sitting on top in the last couple of photos.

    Cool. Do these fir the T3 actions?

    And given that the T3s are all the same length with the LA using a different bolt stop and magazine does that mean the medium action (say my 7-0 will also fit?

      Yep, any round that fits in a short action AICS magazine will fit.

    Fully fitted out with skins, a picatinny spigot and a Limbsaver pad will be around a grand. Time-wise around a month hopefully, I need to get a rifle to check how everything fits up. I don't want to make any promises yet but it won't be too far away.

    Awesome work gregt, pretty sure yours will be better than any other clone chassis of this style. You know I'm interested. LH for me.

      They look like they will be mighty fine, I'm interested.

    I got the other side of the action blocks and the front and rear spigots sorted today. The 2 on the right hand side with the longer bolt cutout lugs are going to be Savage ones. I took some video of some machining today, I'll edit it down and post it up to youtube at some stage.





    The next couple are with the front and rear tubes and rear butt piece sitting in place:

      Looking great Greg!!! Will they be anodized?

      Mate just wondering if you could make the SAKO TRG bipod fit your stocks thanks.

  • #6
    Yep, anodising is looking like the go. I normally cerakote them but this is a lot to cerakote. Spraying inside the tubes is a prick to do as well so it'll solve that problem.

      Sounds good will provide a better finish too

      Good excuse to buy another T3 Tikka.

      308 Win 600mm Barrel in Stainless is my next planned purchase.

      Bling it up with a Nightforce scope, Lumley bolt handle and shroud,AICS mag....

      Any other suggestions............

        I'll have a few more photos tonight, just finishing off the spigot adapters for the front tube at the moment.

        What would people prefer on the front of the stock, a spigot adapter to clip accessories into like an AICS or a short picatinny rail in the same position that was permanently mounted?

          Front spigot and rear butt spike are my preferred options.

          A spigot given the Viperskins can take rails

        Here's a bit of progress, all the fiddly little bits like the tubes, spigots etc are finished now. I drew up the sling loops and they're getting laser cut from steel. I'm also going to do some to suit flush cups if anyone's interested.

        Here's both bipod adapters I'm making, one is a straight Picatinny rail that replaces the front spigot, it'll also be hollowed out on top and have 2 flush cup holes in the sides above the middle rail slot. The other takes all the regular spigot accessories.




        These little spigot adapters are fiddly suckers to make, there's a lot of operations for such a little part but they came out well The lever is spring loaded and pivots on a hardened steel pin. The regular sling loop that hangs out the bottom of the stock pivots off a pin in the bigger hole at the back.




        Here's both types with a rail mounted and a spigot mounted bipod attached.






        A few of the front and rear tubes. The rear tubes will have stainless thread inserts (nutserts) in those counterbored holes for the cheekpad adjuster screws.


        Here's a bunch of the front tubes, they have the Anchutz type rail slot on the bottom as well to mount other accessories. The hole closest to the front is where the sling stud hangs through.

          Great work Greg, I wonder if there would be enough width in the insert block to inlet for a sako trg bipod. When I'm in melb next week ill take some measurements

        I tried a few different bedding methods and a V-block came out on top, the action locks in there beautifully. I got it all drawn up on Tuesday and made a plastic prototype just to make sure everything will fit, it actually all fits in really well. I've machined a pocket to take the Sterk hardened recoil lugs, it's not worth me making them myself given the work that John has put into getting them right and the price he sells them for is excellent.



        Here's a few machining pics from today..

        Setting the blocks up square within +/-.01mm end to end:





        The relief holes at the corners of the magwell centre drilled:



        Then drilled:



        Roughing out the V-block. It's cut in 1mm steps:



        Then the top half of the magwell whichl will be finished from the bottom side, it's still got .5mm to come out. :



        With the roughing out finished, before finishing the V with a chamfering tool:





        Then a run around with a 45 degree cutter to finish the V:





        The V-block finished:





        A few with the top just about done, ready to machine the action screw holes, trigger pocket and recoil lug slot (there's also a left hand Tikka & Remington one in there )



        Some more photos to come tomorrow.

          Greg

          Looking good, real good.

          Just trying decide on calibre. Thinking of 300 Win Mag so that I can get out past 600m.

          Specs so far:
          T3 Vartmint Blued barrel and action
          300 WIN Mag
          620mm Barrel
          Grey Viper skins,
          Sterk swept bolt handle
          Sterk recoil lug
          Titanium bolt shroud
          Muzzle Break?
          3-12x56 PM2 Scope
          Sphur 20moa mount.
          Atlas bipod

          Any thoughts, input will be appreciated.

        Hey Digger, these ones are short action but there is enough room by the look of it to do a long action in the long action skins. I've got an AI 300WM magazine here at the moment, I'll do a bit of measuring up tomorrow and just make sure it'll fit within the skins with room for the release lever. The rest of it is pretty much all the same given Tikka uses the same action for both short and long action.

        These chassis need the long action bolt stop because the mag sits further back than the original Tikka one. I'm going to make a bunch of the little bolt stop levers to suit, if I leave the rear of the mag in the same spot as the short action it shouldn't be a worry. Those 10 round long action mags are absolutely huge though! I'll post up some photos of what it looks like tomorrow.

        Edit: photo added.

          Terrific work, I love threads like this with plenty of machining photo's.
          and btw what's the gizmo in the background (something to workout the z-axis offset for individual tools?)

            Thanks Brian, I agree, machine porn is great. I'm more interested in seeing how something is made than seeing the finished product.

            Yep, the gizmo is a tool setter, you just bring the tool down until it does a turn of the dial back to zero and then set the tool length offset in the machine. Set the longest tool at zero and program the offsets on other tools to make up for the difference They sell an electronic one for this machine that you can just click the mouse and it will touch off and set the offsets but I don't do a lot of production stuff so the dial one does me. It's only a $100 Chinese one but it does the job really well. I also tried out that shiny 3 flute high helix cutter for the first time today, it buzzes through 6061, I think I might have to invest in some more.

              Looking very good Greg, although i'm surprised you didn't get yourself a leftie Tikka!
              Thanks for the machining pictures too - love seeing how it's made

            Love seeing quality work man ship . Between you and sterk your threads are sweet . Can you post a pic of what the finished product will look like ? Im not familiar with these stocks . Currently in the market for a stock for my 300wm . Cheers
