First off a huge thank you to
@BABIS1098 for setting off the idea

So here's my little process of fitting the Origen to the IPV.
I don't have access to a lathe anymore so I decided to give it a try without it and it turned out to be soooo easy...I actually had a chuckle at myself afterwards.
All I used was a electric drill, a hacksaw and sheets of different grades sandpaper to smooth things off.
I clamped the IPV ADA by the thread side in the drill and sawed it off to get the flange off the ADA. I then gripped the ADA flange by the thread side and smoothed it off on the sandpaper sheets.
Same with the Origen. Grip it by the 510 thread in the drill and saw it off while spinning the drill.
Sand the bottom of the threadless RDA on the sandpaper to smooth.
Now the ADA flange can be screwed into the RDA. A little bit needs to be taken off the head of the Origen squonk pin so it can fit into the little black isolating ring. Do that by clamping the squonk pin in the drill and feather it with sandpaper or a handfile
Now its easy to just fit the flange to the RDA
I built a. 2mm 0.3ohm SS coil and it vapes beautifully. Takes this IPV to a whole new level for sure. Don't know why but the temp control don't work as well as in the standard ADA. It does cut back the power but only after I get the dry hit. Don't bother me much though, as i'm still to much on a high for actually getting it working.
