Re: [RE-wrenches] Battery corrosion issue

2016-01-21 Thread dan 
Last summer I had to recast a post. A first for me. Some "Battery Expert" installed a bank of Trojans with UT posts using flat cable end terminals, then torqued the b Jesus out of them to try to get them to seat. what happened was they either cracked or totally broke off the terminal at the bolt hole. Borrowed a terminal mold from Babe down at Interstate, and use an old manual soldering iron (the kind you have to heat up with a torch or something) so i had plenty of ummph, but no open flame around the battery. Cleaned and tinned the busted terminal first and then set up the mold. It wasn't pretty, but it worked. dbDan BrownFoxfire Energy Corp.Renewable Energy Systems(802)-483-2564www.Foxfire-Energy.comNABCEP #092907-44

Re: [RE-wrenches] Battery corrosion issue

2016-01-21 Thread Luke Christy 
I would go with the puller idea. Grab a small gear puller at Napa or Autozone 
and use a large socket or something similar as a spacer on the back side so 
that the puller jaws don't dig into the soft lead.
The challenge may be finding a puller with a small enough bolt to push through 
the terminal hole.

I have also had luck driving out broken bolts with a pin punch. It can get a 
bit dicey though as you have to back up the terminal with something massive to 
absorb the force and keep it from bending and it really requires three hands to 
achieve.

I personally would try to soak the offending post in a solution of baking
soda or some other corrosion remover for a while and then gently tap the
bolt on both sides. Continuing to do this will eventually loosen the
bolt.This IS a thru bolt not something that is threaded. certainly one can
drill it out using the step approach  1/8 " then 3/16 then 1/4 till you  get
to 5/16. Gently tapping or drilling you should find this removal easier then
you thought. Tump

Re: [RE-wrenches] Battery corrosion issue

I wonder if by the rounded shape of the flag, Todd's idea might work 
fine with still a significant amount of contact area.

Re: [RE-wrenches] Battery corrosion issue

2016-01-21 Thread Tump 
I personally would try to soak the offending post in a solution of baking soda 
or some other corrosion remover for a while and then gently tap the bolt on 
both sides. Continuing to do this will eventually loosen the bolt.This IS a 
thru bolt not something that is threaded. certainly one can drill it out using 
the step approach  1/8 " then 3/16 then 1/4 till you  get to 5/16. Gently 
tapping or drilling you should find this removal easier then you thought. Tump

Re: [RE-wrenches] Battery corrosion issue

2016-01-20 Thread Ray Walters 
The EZ out is for unscrewing a threaded connection,  I've spent a bunch 
of time with those only to have the EZ out break off in there too.  Then 
you've got a real mess of hardened tool steel.


I would first drill several small 1/8" holes in the lead around the 
circumference of the bolt.  Then, I think tapping or pressing it out is 
the way.   The wheel puller would probably work.  You'll end up with an 
enlarged hole that you can either use a bigger bolt, or washers to deal 
with.


I agree some of the hardware that comes with cheaper L 16s, is 
inferior.  I've had plenty of those square heads come off with minimal 
torque.

Kristopher,
You might start with a smaller pilot hole and an easy-out or other
screw extractor. I have never seen this, so consider it just a
suggestion.

I'd try an EZ-out screw extractor bit. Handy to have a whole set in the
