A minor disaster this morning.....broken-off nipple in P-H rifle.

This is a now-rare, almost unfired, all original Parker-Hale from around the late 1970s' with a serial number in the low-400's, probably $1500 on your side of the Great Water.

Does it have a heptagon bore like the original Whitworth?

EZ outs in my estimation need to be tapped while turning and are extremely effective if not “easy” to use when extracting broken threaded stuff.

Right upto the point they snap!

Nossir. Just like the original Whitworth, it has a hexagonal - six-sided - bore, rather than a heptagonal - seven-sided - bore.

My experience using them also . I think my "success" ratio is about 20% with sizes under 1/4"

Wow

great pictures

in the USA it's probably only worth about $4500 because of the broken nipple

you are very fortunate to have one

love the bullet too

I often have to remove 2-56 screws that have sheared off under high g

The metal they are broken off in is stainless steel

I use a milling machine, number 50 carbide drill, flush the area with Tap Magic

With everything locked into drilling position, the drill is advanced 0.001" at a time with perhaps 200 rpm

as the drill advances cutting are blown clear with compressed air

this setup and method helps to keep the drill from sucking itself into the work and breaking

the pieces rescued with removal of the broken screw saves a minimum of $1500 and likely more in today's inflation on each one I rescue from scrap bin

We have EasyOuts in the US, mechanics use them almost daily for busted off old bolts and screws.

I honestly have this same fear with a used percussion revolver with frozen nipples I have. I'm afraid my ratcheting nipple wrench will bust the threads off

I'd drop that much in a heartbeat! for that

I certainly hope you mean mechanics all over the US periodically use, and not mechanics in your home town place of residence on a daily basis.

The real pro's have an electrical tap burner that eats the offending material using an electric arc without damage to the workpiece

For every easy out I have used to remove a broken bolt, I have a handful of easy outs I have broken, reground, and broken again. They are the last resort when at sea and the boat is sinking.

They may also be referred to as "cussed things".
