RM3 has 2 airholes?

[camerajunkie]

I've been starting to build dual coils on the RM3, always built a single 1.2 Ω. I've noticed the RM3 gets extremely hot at even a 0.6 ~ 0.8 Ω. Searching through here, I've been reading that a 3-post dual coil RM3 comes with 2 airholes, but the 2 I've owned only have ever had a single airhole.

I've widened the RM3 stock airhole to 1/16". Is it a good idea to drill another hole of the same size for the 2nd coil? The flavor is great right now, but the RM3 is getting quite hot.

From what others have said.......the rm 3 base is the same, but you can get a single air hole top cap, OR a dual airl hole top cap. Rob might could sell you a dual hole top cap

^^^ yup, this.

The cap is the only difference between the single and dual coil versions that Rob sells. I'd want two air holes for any dual setup.

I never saw the option when ordering, I guess I can put my rm3 top cap into a bench vise and drill a 1/16" in, will this mess anything up? I've done it before on other atty's but wondering how it'll effect the vortex etc.

You can drill your own hole - won't disturb the chamber funtion. A drill press would be indicated - they're tiny lil suckers, those atties. Alternatively, if you drill a starter hole (not all the way through and of smaller diameter), you can use a bead reamer or conical file to finish for more precise work.

You'd want to go ahead and drill the second hole 180 degrees from the first if you are going to run a dual coil in it.

The three post bases are confusing maybe when they are used for both the single and dual caps. But it does give the option of turning a single into a dual. My A6 single that is BF'd only has the normal two posts.

Yeah I marked it out, just need a drill press or like @Papa_Lazarou stated with a bead reamer or conical file. I was more concerned if in any of y'all's experience its detrimental in having another 1/16" hole.

Actually on the RM3 top cap, if you are going to drill a 2nd hole in it you can go through the one hole you have and it will act as a guide to go straight across the top cap to drill the 2nd hole. I have done this a while back on some Igo atties I had once.

I have 2 RM3's with two holes and traded my RM8 for another and it only had one hole. Think the person said it was an older model. Not fooled with it yet.

Both the single and doubles are available on the Reo website. The base is the same but one comes with 2 holes and the other with one hole. I don't know if Rob sells the tops separately in the event you want to go from 1 hole to 2....and of course, there is always the drill option

Thanks everyone for the tips, just ordered an 8-inch drill press.

Tracey, you traded your RM8 to me ^_^ it's got a 0.27 ohm twisted 2 strand dual 3mm coils on it right now.

I think in my circle of friends when we ordered our dual coil rm3's we got single air hole top caps.

I'm sure if you emailed or PM'd Rob, that he will set things right.

It's really ok, I ordered a drill press for other reasons of just making an air hole for a top cap.

Yes I broke 2 1/16th drill bits on the top caps, but I was able to exchange them and I'm learning about drilling small cylindrical items.

I just thought it was weird that a dual coil atty came stock with one airhole on every 3 post dual coil RM3 atty I've seen, which is 4 so far.

Also the dual airhole top cap isn't listed as an option on the site, it's either single coil or dual coil RM3, between myself and a co-worker, we've ordered 4 dual coil 3 post RM3s and they all came with single air holes.

I got a few RM3's a while back over the course of about 2 months. Always ordered the dual coil version. One order came with the single coil caps - one message to Rob and he made it all right. Mebbee reach out to him to check out your options (never hurts to have 'em).
