What do you mean the 510 wasn't tapped through?

So your reference mod read 0.004 with the copper rod?

With the ball of copper wire I got 0.010 but used 0.008.......mine is the black anodised reference mod (sent my original in for repair and they sent me back a black one!.....Yay!)


Where did you get the copper rod and is it solid I'm assuming?

Look at the pic on page 1 you can see it sat proud, I got a plug tap for 4.50GBP from eBay and ran it through and now it sit flush.  Yes it measured 0.004, I posted a pic on pg 3, and I didn't have to put as much pressure as with the VT and expect it is a frication lower res. I saw your black one, we are all jealous.

I got the copper rod from eBay a while age for another project, I have some a bit thicker that I need to put in the drill and file down so the M70.5 die I just got from China for <2GBP can make a solid copper one.

Do you mean the 510 wasn't screwed all 4th way down into the box?

Yes, the threads were not tapped through, it was tight, but not fully screw in, the top was 3-4 mm higher than it should have been. Quite a lot of aluminium came off when I tapped it fully through.

Yea my black reference mods 510 doesn't sit flush neither but my original raw aluminium one did.

So screwing that down further gave you less resistance?

You will have to get a 1/2"x20 (1/2" UNF) thread tap and a pin wrench, adjustable with 4 mm pins.

One very important thing is you have to either take the centre pin out buy removing the circlip or disconnect the positive out when trying to turn the Evolv 510 or you will twist that wire and could rip the positive wire off the board.

I got 0.004 for my Realeaux with the soldered carto above, I have set it to 0.0036 IIRC Wismec have 0.003 in their config file.

If you buy the 99.9% copp er plug as I did, I was advised to use the actual resulting resistance reading. In my case the Vaporshark DNA200 was ".05", or 005, don't remember after I plugged in the number. It was low!

I received the copper 510 tool today. It is very well machined and works great. If it helps anyone else my Wismec Reuleaux read mod resistance of 0.005 ohms.

Last year I bought the Fat Daddy Vapes 510 tool, about 1/4 way down on the page, right side --> http://www.fatdaddyvapes.com/shop.html Made of stainless, you get two of them for $5, I used them for checking my mods (as well as installing 510's), just take the jam nut off before checking the resistance to make sure you bottom out in the 510. FYI, I use a copper washer between the lock down/jam nut and a 510 when installing 510's so I don't mar up a 510. Also, they don't show in the pic, there is a hex machined in the top of the tool so you can use an allen wrench. I use them to install all my 510's including the Evolv's.

ETA: Here's some more pics of the tool.

I have built loads of dna devices and i measure the mod resistance with a solid copper threaded knob from signature mods. 
i always get mod resistance between 0.005-0.002 ohms

I have just done my first dna250 (massive with a turnigy 4000mah 3s2p graphene lipo) 
and it reads the resistance as i screw it on like normal but when it makes good contact it shows?

does this mean there is 0 resistance in the mod?

is this even possible?
