Easy mod to Octopus RDA

[Xobeloot]

So as many have said, the Octopus is a great little dripper, but if you have anything other than a desk job, you run the risk of the cap popping off (rather easily).

I had a few extra SS set screws (sorry, dont know the exact size). I opened up the stock airhole enough to allow me to tap it using the screw.

Drill a new air hole and call it a day. My octopus can now take a beating without opening on its own!

nice gonna have to look into doing this to mine!!!

GREAT! This would apply to lots of RBAs with loose o-ring caps. Instead of drilling a new air hole, tho; one would just drill a set screw hole.

Just as additional info, the screw does actually tap about 1/8 inch into the inner base.

I'll add pictures of that in an edit later. Unfortunately, I stripped out the only hex key I had that fit this screw while threading the hole.

Trip to harbor freight this afternoon!

Yeah, I figured, since it was originally an airhole passing through the base. So, with an rba with side air hole, it would depend on the thickness of the cap. If the cap had some body to it, the set screw could just press against the base. If the cap were wimpy, one could dimple the base with the drill as well.

 

[Xobeloot]

Yeah. I'm looking to swap out the o-rings for a slightly thicker gauge as well.

Yeah. I'm looking to swap out the o-rings for a slightly thicker gauge as well.

Exactly what I did on all mine, caps are very tight now.

I wrapped some plumber tape around my octopus and put the o rings back on over the tape and it holds really well now

I wound up wrapping a couple wraps of dental floss under each ring. Eliminated the mild leaking i'd get if I got a bit too generous with the juice.

my octo's stock o-rings are tight as hell. i can pick up my octo by the shell while attached to my provari, shake vigorously (not that i would actually do that, but still) and the top cap wont budge. it actually takes quite a working with your fingernail to pry the top cap off. its strange how identical devices arnt so identical afterall.

 

[RelativeBewt]

great idea! i just drilled a new air hole on mine so i think im gonna give this a try

 

[Xobeloot]

Yeah Kemo. With as inexpensive as they are, I am not shocked by the broad tolerances.

All seem to be easy tweaks though.
