Pin removal tools - lose less wire

Don't know if this has been said yet.....I looked/searched for this tip
but didn't find it..........but first I must say that.........

I'm a novice (only fly a HZ Super Cub). Knew I was having troubles
with battery/plane connections.....could hear motor cutting out. Changing
out connectors without being able to remove the pins from the original
connectors meant losing more wire than I wanted to...it would be better
to get the pin out. Trouble is, I didn't want to pay big $$ for a pin-pusher
type removal too. I also didn't want to go through the hassle of
cutting the original connector apart....

So......

I had an old rabbit-ears TV antennae. Each section of it looked like a good
'pin-remover' tool to me. I clamped a Dremel tool in a vise with a cut-off disc
on it, and turned the antennae shaft against it. You have to cut off the
bottom 1" of the lowest section, as well as the tip-top. Then push all the
sections out thru the bottom one. I wound up with 6 different
'pin-removal' tools....thin-walled, strong, and they do the job for me.
Just push them into the end and experiment with the different sizes.
Note: Each tube has actually 2 different sizes - the crimped and non-crimped end.
I swaged out all the crimped ends just a little so they wouldn't tend
to "hook" the 'keeper tabs' on the pins you are trying to remove.

These thin-walled tubes make great pin removers, allowing you to
waste the least amount of original wire. I lost only about 1/8" of each
wire. I think there are lots of antennaes out there on junked boom-boxes,
radios, etc. just waiting to be used.

Just a thought - hope it helps somebody.

PS - I switched over to computer power-supply connectors, not being
flush with money right now...plus I had oodles of them from scrapping
out PCs. For my low-current plane they work fine. For you advanced
flyers they are probably a little light. Yeah, I know about Deans.....

Thanks for the idea. I have "fought" those blasted pins for years. Hope I can find an old rabbit-ears antenna like you did.

These must be the Tamiya type battery connectors, I can't think of another battery connector that can use that type of removal tool. Ball point pen ink tubes could be used to make those tools too, another source of material was the brass tubing from the rack of various sizes of telescoping brass tubing at the LHS.

I don't use very many of them but one battery connector that I have never been able to get the contacts out of without destroying the housing is the small red JST connector used on some real small batteries and in some of transmitters.
