What work did you just do?

[crossliner]

The ss washer is this type of bumper bolt because the ATI cheekpiece has a square hole. I chose one that would fit the hole "squarely", lol!

I had the bumper bolt refaced, cut then drilled.

Inspired once again by plasticclassic's stock for sale and the AA TRD I made this stock. Still needs some refinement, but closer......

Nice Rich - thickwall tubing or solid aluminum bar?

This one is solid as I had it on hand. I also used and re-drilled/tapped the brass PA that I had drilled/tapped with 10-32 instead of the 8-32 that is needed. That needs replacing with SS.


Last night I shot it and discovered that the cheek riser won't work so I am going to remove it and add a delrin tube in its place. Also, need to cut down the butt pad and reverse the top bend.


On the next one, I'm going to try to find a shop with a bender. I think a 1 to 1-1/2" drop would allow for the adjustable riser to be used. I like the idea of having that option (plus, I think it looks cool). Will go with SS on the riser legs next time too. I have a bunch of AL shorts left over from Arky-pod legs that fit the bill for this prototype. May do something more AR style with the butt as well. I have more ideas right now than time   
Will update in a few years

I had the same issue with my LW66 build - power adjuster and straight stock in line with the compression tube did not give good cheek rest positioning.

That's why I went to the modified 1399 stock. Raising the sights helped too.

I am using relatively thick-wall 7/8" aluminum tubing.

Finally got a picture of the 1740 I made earlier this week:



A close observation might reveal that the elevation scope cap is still in my garage

I like the stock arkmaker. Is it something that may be available?

Nice work on the rigs fellas, keep it up!!

Looks nice, have you got a chance to shoot it yet ?

Very nice. I have a similar rig (1750) that is my go to gun. Share the numbers you get with yours?

I hope it's not under that woodpile.   

[rangerfredbob]

Lol, no, it's in the garage where I sighted it in

When I get a chance to shoot it more I'll try to pull the crony out and see what it does

[o-townFLA]

Well it started out by making a pivot pin. As you can see the brass was a little weak after (2) 10 pump trails. I then made one out of a worn out 3/16 drill bit. That didn't work out either. Found a piece of stainless steel stock round and it seems to be working for the moment...



I also tapped my FTP for some off-setting set screws... I was pretty sketched as I didn't wanna ruin the Alchemy Airwerks FTP...




I then made my own brass safety and went to town polishing.
