bending 200 resistors

[Johan Wagener]

I need to bend more than 200 resistor leads before I solder them to my
pcb. I can't seem to find one of those resistor lead bending tools.

Any hints on how to accurately bend them all so that they fit
perfectly?

If you're in a bind, make one yourself. Get a piece of hardwood or metal which
has a width greater than the distance between your PCB holes. Mill it down so
the width is one lead diameter less than the distance between your hole
centers. Mill a small groove across the width of the piece such that the leads
will fit securely. Then mill out a concavity in the center of the piece such
that the resistor body will fit inside without touching the piece. Then just
insert the resistors, and manually bend the leads down with your fingers. If
you need a hint, punch in the number at JAmeco.com and look at the picture.
Voilla.

This is one of those cheapie tools that wll last at least one lifetime. Gotta
buy one sometime.

Good luck

Heres a Fresh New Idea.

Do you have one of those spray cans that use the long plastic Spray tube to
get at hard to reach spots? Well, take that tube, cut part of it off at a
length that the resistor will bottom out at one side at the appropriate
length for your bend. Use your Finger on the end to make it bottom out. Bend
away !

I got a very similar jig free with an electronics mag donkey's years ago, be
nice to say it's still going strong but I lost the beggar.

Now I use a scrap of perfboard sawn through the holes.

Was it Practical Electronics? It was imported here to Canada,
and they often seemed to have interesting things. Fairly bulky things
taped to the magazine. I'm sure I bought the issue with the bending jig,
though I can't recall every using it. Salvaging resistors off circuit
boards means there isn't much lead to work with. And if I did indeed buy
that issue, I sure don't know where the bending jig is.

Johan Wagener:
Make your own bending jig by filing (or cutting with a hack saw) properly
spaced notches or grooves in a cheap plastic ruler.

wow, a lead bender hard to find......mouser, jameco, electronics
express, contact east, allied electronics..........they all carry them
from the cheap plastic forms to lever action bending tools.

I once had to bend a bunch of diodes for a high voltage generator and
this was before I had a commercial lead bender....I used a strip of
perfboard cut to where I had 2 half holes on each side thats width was
the same as the holes in the pcb. You could make a multiple size
bender this way too just cutting the board diagonally on each side of
a center line........but I would just buy a cheap bender. Hope I made
that clear enough.....

buy a plastic bender..... they are a cheap tool and worth the small
cost.

Could well have been, but I'm talking over 30 years ago...
