Thread: Post your mystery tool.

This little bloke mostly gets used around home as a marlin spike but have a guess at what it really is for,

looks like a centering tool to me.

Its a chamber wear gauge for a .303 Lee-Enfeild rifle. The more you shoot the more the chamber wears out, so when this gauge fits completely into the rifles chamber the chamber is worn out and the whole rifle barrel gets replaced.

Bit of a long-winded way to do it, it'd be a lot easier to just buy the fittings from wherever you bought the 1/4" schrader to adapt, wouldn't it?


Dave, other than Hitachi even old school refrigeration use schrader valves. If one's not fitted, like on a domestic fridge maybe, you'd use piercing pliers or a line tap valve to gain access.

In addition, the screws don't look long enough to ensure a good seal - if the part that fits under the plate is a male flare, then it'd need to be a pretty shallow fitting for the screws to hold, I think. It may fit a Hitachi valve, but the screws are on the wrong side for easy manipulation in that case.

If I'm wrong I'd love to see photos of it in operation.

This looks like it may be some sort of testing / comissioning rig, with the 1/4" conection for attatching a Nitrogen regulator to set up some form of switch or other pressure device prior to installation?

thats why I thought it was for vacing down. put an olive in the male flare, connect it up and then secure the flare under the keyway and vac away.

once youve vacced down close the service valve and your done.

spose on the other side of the bore tool its got .303 on the same line as the LB

I found that in an antique shop in Henty for $2 as a kid. Have been using it for rope splicing ever since. Its was at the Sheperton gun show when I found out what it was for.

I had leaking transmission cooling lines on my Disco. The hydraulics bloke sold me some rubber hose and the fittings to weld to the steel part of the line. When I installed them one of them leaked from my weld.

As they are a bit of a bugger of a job to remove them, I made this tool to pressure test them before refitting. I seal off the other end of the hose and then fit the opposite end into the tool. I can then use my fridge gauges to pressurize the hose and check for leaks.

In my next photo it is obvious what it is. The question is, what was it made from? My father had this made about 50 years ago.
