The PTB Pillow:
I haven't been having the best of luck with any of the mods I've tried on bigger carts, but an experiment this morning with my 701 e-cigar seems promising so I thought I'd put it out there for
testing/refinement and perhaps use on other/smaller carts.
For materials on a 701 this requires about a half a PTB, some stock polyfill (I used all the poly from a 501 cart) for this one, and a fat straw to keep the thing up (McDonalds-size).
I'll be using some needle-nose pliers to make life easier (isn't necessary perhaps), and a pair of crappy scissors. The scissors will be even crappier when I'm done
Step 1.
Clean the tea out that PTB, pull the string and tag off and give it a rinse.
Step 2.
Cut all the seams off the teabag, leaving a rectangular sheet.
Step 3.
Cut that sheet in half.
Step 4.
Take a wad of polyfil and form it into a loose ball.
(how much depends on the size of your cart - for a 701 cart I've used as much filler as a stock 501 holds - which is probably less than a third of the stock fill that came in the 701).
Step 5.
Put the balled polyfill inside that half sheet of of PTB, 'wrap' it and twist up one end (kind of like a tootsie-pop wrapper
Step 6.
Hold the twisted end with some pliers and start heating up the tips on some scissors. These are going to end up with some melted gunk on them when you're done - so don't use a good pair. (I think blunt may actually work better)
Step 7.
Make sure the scissor tips are good and hot - you want to 'melt' through the PTB - not really 'cut' it. Now scissor-melt the 'tail' off your wrapped poly.
If your scissors weren't hot enough you may not have sufficiently melted the PTB together to 'seal' the polyfil in it's new pillowcase. If they were, the twisted material should be melted/bonded together, and at this point you're left with what kinda looks like a garlic bulb.
Step 8.
Cut a straw to the right length to prop the pillow up to more or less the very top of the cart. Notch it away if you'd like, the straw is just there to keep the pillow up top.
Top of your cart with the straw in place, put the onion on top with the twist facing downwards (into the straw), and you're done.
The pillow seems to rinse easily for re-use and 'fluffing', the poly seems to breathe well enough to minimize vacuum locks while the PTB case keep errant fibers in place, and so far at least I'm not seeing any leaking issues.
