Never heard of them! Send me a head down and I'll have a look! Pm me for my Addy but I'm not promising!!

Cheers, they are like a aspire coil

Want to have a look but reckon yes. The head would have to be drilled out and then microcoiled horizontally send me one, pm me for my Addy, if I can do them then you can send loads down. regards, Paul.

Cheers message sent, thanks Glen

Cool, i've a few need doing and will happily pay all costs

[prr]

Bluefish you very kindly sent me some Jacques le Mon, if these heads work my pleasure to do them for you. You wouldn't accept postage even, neither will I.

as im not sure what your drilling this may be wide off target for you But having had to drill a few SS pots n pans ive found its a lot easier to enlarge a puncture hole than it is to break through a stainless steel skin so if applicable a sharp punch and a good whack with a amma can make some jobs a LOT easier, Also battery drill drivers with speed control seem like a good idea to drill slowly without work hardening the SS But a mains powered drill pulsed on and off with the work surface /drill tip cooled with the odd squirt of wd40 is VERY effective even tho its a 3 handed job and allows the use of basic HSS jobber bits to be used for the job

Right, was getiing a little leakage and a bit of a thin vape using the long tails of cotton and wasn't that happy. Have now drilled the two holes out smaller and used silicone to seal the other two holes, guess what? This is working, will give it a few days to ensure it works properly.

Are there any potential issues using silicone, I know many atties use silicone Orings but maybe that's a bit different from having silicone quite so close to the coil. 
Im not saying it is an issue, just thinking aloud.

That concerned me at first Greg however tanks are sealed by silicone rings, protank coils have silicone grommets and these take the heat generated by the coil. The bvc heads have an inner sleeve hence the need to drill out, the silicone is merely sealing the very small hole. Think of the chimney caps on any of the protank, close to heat and in the liquid.
