Keep em tight

[super_X_drifter]

Just a reminder to check post screw tightness on your RBAs from time to time and as a first line defense against anemic vape.

You would think as .... as I am I would never have loose screws. Early yesterday morning I took the rba off my .21 voltage drop freshly rebuilt grand to take a picture for another thread. So I hadn't vaped it yet ( I have several others sitting around to vape )

When I put the rba back on and vaped it, it was good but it didn't seem to be packing the punch I remembered from Saturday.

I unscrewed it and put it back on and it was a little better. As the day went on I got more curious and looked at my coil. I noticed that it was a little more slanted than usual so I went to adjust it and it was loose on one side.

Tightened it up and now it's sizzling and churning like crazy. Checked VD this morning and with a 4.20 battery it's 4.01 VD. Less than .2 volts lost. That's amazing.

So check your screw tightness more often - you could be missing out on the full potential of your setup

Good reminder, Supe. Usually I just flick the coil to see if it wiggles when swapping wicks.

Been there too. Was getting a very weak vape which won't improve after cleaning my positive pin. Decided to clean the coil by dry burning it with no wick and saw some arcing on the poles. Turned out one of the screws on my RM2 was loose.

That happens CONSTANTLY with mi igo-W.

After installing a new build and test-firing, the negative post screws seem to loosen themselves. I'm sure it has something to do with the coil legs heating and expanding/contracting. I almost always have to snug the negative screws.

On some atomizers, there seems to be a fine line between snug and the point where the wire snaps.

Hear here Super.

It's nice having the phillips screws, but one trade off is they tend to not snag down wires as tight as the hollow hex ones do, especially if your rockin 28g or thicker, they can easily "bump" themselves a bit loose.

Investing in a sharp quality precision screwdriver goes a long way here too so you can get those screws tight without stripping them. The more solid the mechanical connection, the harder she hits!

Cheers

Since this happened to me I now check my post screws almost daily... Just in case!!!

a screw upgrade and a nice hex driver has all but eliminated this issue for me.

the atties i have all came with screws with bad tolerances on the threads. they move easily due to the tolerances.

i use these on my atties... McMaster-Carr

they require a 1.5mm hex driver. this one should do fine... Turnigy 1.5mm Hex Screwdriver (USA warehouse)

the RM2 would do fine with 3mm long screws, but 4mm fit fine and will work with more atties such as the igo-w and igo-l.

i'm sure you guys have seen this before, but here goes...

if you really want quality drivers (which you won't really need for an atty), these are the ones i use for my RC's...

i use them because hex grabs better, slips less, strips less and allows you to apply more torque due to 6 points to spread the pressure without stripping the screws. tiny stripped screws in a thousand dollar, plus investment sucks...

So all this time it boils down to, if yer vape sucks you have a screw loose?!?

Essentially, one way or the other.

yea. its a must to check this, I find after a fresh build and after a few good vapes, I check the screws or allen set screws are
still tight.. after that I'm pretty much set.

be a happy vaper and check for tight screws
