Thread: Mystery tool teaser

It looks like a swageing tool

Cheers
Michael

I'de go along with that , a cutter at the back and a swageing at the front

A battery Lead Cutter And Terminal Crimper (installer) for cars/trucks
Down the back cuts the lead.Up the front is the crimper.
Only basically does the one size.Otherwise it would have 2 or 3 sizes of crimper on it.
I suspect the Bronze bit you mentioned is to measure the amount of insulation to cut of.Not needed arter the first cut.

No one is correct as yet - please keep trying!

Did it have something to do with an old wood stove ???

Warrick

Rivet holder.

Looks like a detonator crimper

One of the "jaws" is for cutting the safety fuse, the other for crimping the fuse into the detonator.

added: oh, and one leg is designed for poking a hole in the stick of "gelly" so you can insert the detonator

Looks like an old version of an electrical wire cutters and crimp lug pliers, bit hard to tell from the pick or a lead bullet (projectile) trimer and crimper.

I recon Ians right as I found the following drawing for a Double-crimper for blasting caps

Hey there,

I believe Ian and Warrick are right, they look like my pop's old Powder Monkey pliers, the bronze bit stops any accidents while making the hole for the Det.

Ian was the first with a correct answer – it is a pair of Detonator Pliers.
(Called Blasting Cap Pliers in USA).
Well done! So quick! I thought it may take a bit longer.

It is meant to cut Safety Fuse cleanly with a scissor action to get a 90 degree face on the fuse end, and to crimp the aluminium (or copper in the very old days) detonator tubular casing onto the fuse cord.

The pliers also allow the user to easily make the correct size hole in a stick of gelignite type explosive, so that the fused detonator can be placed in the explosive.
Gelignite looks and feels like a cross between home-made white coconut ice and sugar slightly moistened with a small amount of light machine oil, then compressed and wrapped in greaseproof type tough paper.

Most small stick nitroglycerine based explosives in the old days were roll paper wrapped, and the Ahrems plier handle has a hollowed out bronze end to act as a combined hollow drill and reamer to make a neat hole in the stick.

Attached is another similar tool, an ICI Det Plier, which I purchased new in Brisbane in 1972 from Banks Hardware in South Brisbane.
This tool just has a tapered handle end to poke the det hole into a stick, but it worked well, making a “nice slice” fuse cut, and with a very well formed 360 degree crimp.
It looks “basic” but works.

In those days, I only had to have a Miner’s Right to purchase explosives and tools. Banks Hardware used to even store explosives in a mini magazine out the back of the store, almost in the middle of Brisbane!
They didn’t even bat an eyelid when a very young looking guy in jeans and T-shirt (me) asked for half a dozen sticks of ICI AN60, 30 dets, and a 50 foot roll of two feet a minute fuse.
A quarter stick of AN60 used to crack a two foot diameter rock quite nicely if the explosive was well placed. Very useful for clearing rocks for prospecting

Congratulations again to Ian, and to Warwick.


I might post a few other “mystery tools”, some even related to woodworking, as long as I don’t bore anyone.

Shucks, thought it was some sort of immasculator.

I do not know about them being detonator crimpers but it looks awfully like the pliers my dentist uses to pull out teeth .
