OK. So I found the video I watched months ago. It's actually for a Voopoo pod system but the principle is 100% the same as the design is the same and the same problem exists - the rba has no way to be mounted to a 510.
Now this guy didn't have to saw a pod (I remembered incorrectly) because the pod is so shallow all he had to do is remove the glued top cap. But it gives an idea of what is needed to make a proper building base for similar such a pod systems whether you have to use a saw or now. No matter what, you'll always have to sacrifice a pod to turn it into an rba building base.

Lol like I said Macgyver solution. The reason it is a Macgyver solution because you have to take apart things to assemble something else. Plus like I said there is a way to attach the smok RPM RBA Coil to a 510 but you have to get this Omeka RBA to get the 510 adapter to use with the Smok RPM RBA Coil. This is the simple easy solution no hacksaw or other destructive tools required.
