[TC338]

Looking good!!!! I can't wait to see the finished product.

I spose I can probably skip ahead a little bit now, got a few new bits back - shortened barrel, DPT, fluted bolt and unnecessarily expensive trigger guard.
I ended up rushing the last bit of sanding on the epoxy, but I'm confident I can re-finish it pretty well.

I've already got a big long list of stuff I want to change for the 3rd prototype;
- re-design the comb for a bit more fatness, and the proper clearance for the bolt
- recess the trigger guard properly, and just buy a Remington aluminium one (or similar) rather than get one CNC'd in China :x_x:
- flatter forend for better sitting on a bag or harris-style bipod
- skinnier grip (particularly at the very bottom
- figure something out for grip... not super keen on going down the path of chequering, but I'll see.
- better channel forming around the barrel, and less ridiculous structure in the forend (sling stud reinforcing)
- design the swivel sling studs into the stock, rather than add them later

A whole bunch more stuff will no doubt shake out as I use it some more, but for now I'm very happy with how it handles

I forgot to note, total rifle (as seen above) comes in at 8lb on the dot.

Looks great so far. Very well done and documented. Can't wait to see the next prototype

Once again great job. I might have missed it but what's the little, white symbol on your stock grip? Thanks for sharing!

I started with modelling up the action I had, then converted this into a cutting volume - a digital plug I could subtract from any stock design to fit the howa metal:

This keeps the stock design separate from the action, and means I can tweak the action cutter throughout the prototyping without affecting the stock, and vice-versa. It also means I can theoretically make up another for a different action, and drop it into the same stock design.

This is the oldest concept I can find:

The important bit of this design was to split the stock in half. I originally looked at carbon fibre, but rapidly ruled it out due to it being a massive dick to work with, and difficult (and expensive) to make progressive changes.

Splitting the stock in half, has a couple of huge advantages:

1. The inletting can be machined in one hit from the inside
2. It can be hollowed out, and made significantly lighter

I dropped the idea of the carbon fibre foreend pretty quick, but the idea was that it could be a single cavity mold.

---------------- Any chance you could share those 3d models with me.(preferably if you have them in an stl format or something that i can make work of) Im looking at using a cnc to build a chassis from scratch, your inlet and cutting marks would be extremely helpful. My email is [email protected]
