It seems a lot of we DIYers want to rebuild ni cad packs from 12v drills etc.
Spot welders seem to be the ideal method.

Q) anyone out there built / seen/ used a homebuilt version for this purpose.?

Normal spotwelders for heavier joins are basic mechanics and electrical parts.
Combining the knowledge of a group like this should get a basic design possible i reckon..

Any ideas out there. I can make gadgets in metal but have no idea re volts/ amps needed to make the spotwelder work..

RC modellers/ recycler fiends and DIYers would get a lot of use from such a machine in a community.

Jewellers use them but high cost. Surely the junk brigade can cover the problem?

Any ideas appreciated..
