Not original and 2g heavier than Stu's but all my own work.



Works well with the Alpkit ti cup.

Nice work that. Is it from a couple of those aluminium beer bottles? I made a few similar ones - cut up the bottles and pressed them together with a car jack under the work bench, but I could never get the top to roll down as neatly as you've done there.

I used some aluminium bottles from "The Soap Kitchen" website.
The inner section is a little squint but it works. May try my vice to seat the two sections if i do another.
