One of the last things I try before I banish a Mother F*cker tank...
After checking o-rings, flip the glass 180, as sometimes it can seal better worse
at one end than the other - especially at base
Wick using the Scottish Roll method - which is a little more tedious at first
But found a simple method now...
Peel off a layer, pull out as usual blah blah blah...
Snip the stretched cotton in half & use one half for tank, save other for later/Ron
now the rolling bit is a bit fiddly, so have a look for some twin & earth cable...
using say a 5 inch strip of the bare copper earth in ya mains cable...
(I guess a wire coat hanger might do, but is about 2mm thick but I've used a bit of
lighting cable earth which is 1.4mm on 1.5mm 2+E or 1.78mm on 2.5mm 2+E)
Always found the rolling of wick a PITA, to get started & keep it mildly tight & even)
Lay out a clean sheet of paper or something clean, ensure wire is fairly straight
lay the cotton down, use the copper wire, lightly wet fingers, roll the bastard up in a second
slide out the earth wire, viola - a fairly snug, evenly rolled wick
stuff the wick in there and if that don't help then the tank should perhaps be launched down the garden
I've found that a layer, stretched out & cut in half, creates the perfect size once rolled
to stuff into a 2.5mm coil, sure it takes a minute or two extra to spread/pull the cotton
but next time, I have the other half which is simply rolled in seconds, so no fuss at all
(even quicker than cutting off another strip of cotton hopefully straight & even,
coz the spare half is nigh on ready to go)
It's quite snug, but will likely help if standard method doesn't seem to stuff the wells/channels allowing
tank to flood & gurgle on some tanks, still staying on std 2.5mm coil
The other alternative is to try a 3.0mm coil which requires more cotton & this "can" work better on some
tanks with wider channels/wells to prevent flood/gurgle
(I prefer to stick on 2.5mm coil, 27awg, 7 wraps 1.08 etc... so often use a stuffy Scottish Roll with my bit of wire)
Above all else, using the two halves from one strip/layer I'm getting a couple more wicks per sheet
but most of all I seem to be getting more consistency in this method, than too wide/tight, too thin/loose wicking
What put me off was trying to roll it by hand, but thin earth wire has made it all a piece of piss
& have been wicking like this for last 6 months or so - why I didn't do this sooner is beyond me
*** it will take more "priming" than conventional wicking, don't drown or go nuts flooding the coil,
but be more generous especially at bend/elbows & rest of wick down towards the juice ***
Need to dry-draw bit more & let it stand a little longer before chaining away on a fresh rolled wick
But, yeah, it kinda works a bit better for me & imho worth a tiny bit more prep time at first attempt
worth a go & yields good results I think
best of luck
