The Making of a battery holder

All started with one saturday afternoon drawing with some compasses. There is no return from there onwards, All the tools brought into action. Didn't know that its that difficult to make this battery holder, A lot of thinking and planning, alignment , measure two times then make a cut. Soldering the copper rod was a PITA. Next time I will get a lathe to make things round. Tonight I assemble the whole unit and it works!. Need to find a copper dome for the positive pole. Enjoy! Thanks for viewing.

Nicely done! Thanks for the photos.

WOW! That's awesome. :goodjob:

:wow: You gave that poor Dremel quite a workout making this battery holder, eh? oo: Very nice job and thanks for sharing! :thumbsup:

Yeah, you should consider making some to sell...plus if you could make some to work in parallel connection, that would be unique because no one seems to make a parallel battery in that configuration.

there are two "plugs" with coinslots on the Dremel, remove them, they are the "brushes" for the rotor. You can buy cheap plug and play replacements at any dremel dealer. They dont last that long under sustained use, and are designed for field replacement.

nice batt holder!

Snip - very nice job. let us know how it holds up.

Bush ... err Bushman - thanks for that tip on the Dremel fix.

Do you need 100 pcs of these battery holder or you are asking me to make them for sale at CPF?

I made them during my free time, didnt really time myself.

Thanks for all the comments!

Its not the carbon brushes, I know about the blue color coinslots. Be careful about the orientation after you remove them to check. Putting it back incorrectly will need to run in the carbon brushes again. I cleaned up the armature and the sound was gone. Thanks for the advice

off topic, sorry, but what did you use to clean the armature, contact cleaner or fine steel wool?

light polish like brasso, a bit of it will do.
