Restricted Access Wire Snippers
 
3 Attachment(s)
I have recently been restoring a Philips 371A. Typical of these post war sets is the stacked layout of the passive components. The resistors and capacitors are soldered to paxolin "sprues" that emanate from the chassis making it difficult to access those components at the bottom of the stack. A google search revealed no available manufactured tool that would reach deep into the chassis and snip the component leads. The only course of action was to make my own tool.
Two shaped steel plates closely linked together by screws moving in slots slide over one another by squeezing the handles at the top. At the bottom end, two hardened cutting edges slide against each other thereby snipping the component leads.
Results are very good but for stouter leads a the jaws of water-pump pliers can be safely placed on the handles without risk of damage.

What a good And thoroughly useful idea!
Amazing nobody produces a ready made device.
Any plans for mass production? I’d certainly buy a pair.

Actually be a good topic for another thread.... what presently unmade (undiscovered?) tool would you like to see made?

They look very handy

I'll have a pair if you are getting a production line going! Happy to help with the manufacture if I can be of any use!

Thanks for all of your kind comments. You can probably tell from the shape that I made the cutters from a spare mortise lock striker plate, this reduces the amount of cutting required. These are quite time consuming to make accurately using hand tools. In a production environment they could be made much more rapidly using CNC machining systems and presetable repetitive punching jigs.
The only ready made tool that recognises this access difficulty is sold by Laser Tools, this is a double jointed side cutter whereby the operating levers take up a bit less space than the handles but this tool still does not allow one to cut sideways at depth.

A quote from someone, sometime, somewhere:
"A time-served, skilled and knowledgeable craftsman makes his own tools".
Your product: well done! :clap:

I have a pair of end cutters similar to these lost somewhere in the shed, they were military surplus so didn't cost as much as a new pair.
