Benjamin 317 Rifle Disassembly, Part 2

One last part to remove that's easy...

The manual safety catch unscrewed from the receiver.

Now to remove the valve for resealing...there's a square hollow retaining nut that comes out first. But the square wrench has to have a hole in it to clear the valve stem.

A blurrier pic, somewhat hard to focus down the tube...

I used my collection of brass tubing to determine what the square and hole dimensions need to be. I'll measure all the parts when I do get the valve out to determine what the correct dimensions are (rather than those that worked here...)

Milling the square after drilling on the lathe.

Rounding the corners off to fit the radius of the square.

The finished tool.

The nut removed.

The next bit is going to be more difficult as I need to make a puller that screws on the valve stem. Searching around the forums, it seems as though it's a 9/32"-32 tpi thread. Neither I nor my tap-happy friend Kent has a tap that size. I don't really want to order one so I think I'll try making one from tool steel. If that fails, then I will have to bite the bullet. It's worth noting that you can just buy a tool from Bryan and Associates ($12.95)and on Gunbroker, etc. I'm just trying to do it all myself, for the experience.
