Copper 3.7v Mod

COPPER TUBE MOD:
The one of best material to build a MOD is Copper. Copper is an excellent conductor of electricity. Technically it is better than thin walled tin, alloy, cast or aluminum which are not great conductors.
A "NO SOLDER" PV can lead to poor connections and amperage loss if not properly aligned to the adjoining parts. I have experienced this with a mod I bought.

I have just built a thick walled copper tube mod. More like copper pipe. I soldered the atty base to the copper cap and the atty positive directly to the switch. The switch is a 3amp switch. The other end of the switch is soldered to the positive copper head screw, filed flat to fit flush against the head of the battery post with the entire diameter of the screw covering the entire battery post.

All wire used is 20 gauged for less loss. I opted not to use thin 24-26 gauge telephone wire. The negative spring is a thick diameter gauged chrome plated steel. I would have used copper but the copper springs that I have seen are thin diameter and loose there spring tension. I'm sure there are good copper ones but I could not find any. UP DATE: Installed a Copper Hot Spring made for the Silver Bullet.

My view on the plunger is that the contact point would have to fit squarely flush for best contact. If there is any side to side play/movement full contact may not be achieved. So I went with the 3 amp switch instead.

It looks really good, how much did it cost to make?

3 feet of 3/4" copper tube was about $8 bucks which I only used 5inches of. Can make 7 out of the 3' of tube
$1 for two pipe caps
atty base was $1.99
5 or 6 bucks for a good 3amp PB switch
Had the bat spring but it's about $2
Not including the battery.

To a non-techie your copper mod looks beautiful, BT

Do you think it could withstand a hot-flushy sweaty mitt without going green (the mod and/or the hand )? I wonder if it could be anodised or summat to prevent reaction with skin acids. Or won't it need to be?

(I did say "to a non-techie" )

Really nice bit of modding. The VV model looks great too. This may be a stupid question but how do the caps attach to the body?

I'd get it polished up to a high shine then put a lovely tough varnish on it I think to stop any green incidents.

I await developments eagerly!

Check out the link I posted a couple of times, for details. It will show you how to make the caps.

About once a week, I run some #0000 steelwool over it and in 3 seconds time it's gleaming new. Yeah, that's the only draw back with copper, turning like that. Wear white gloves while vaping

Good suggestion verey, it should hold up for a long time but not forever. I had some varnish coated chrome like that. The finish should outlast the mod, hopefully.
