Never heard it called that....it's aluminum tape with 'peel-n-stick' adhesive.I know it as duct-tape.(the real kind).....hehe...learn something new everyday.
My pump should be here in 2-3 weeks.
I think I've figgered out the easiest way to start siliconing the interior glass.
I'm going to use 'string' to achieve the gap I need between the inner glass and the outer glass......Basically , I'll start by laying 2 pieces of string on the bottom of the tank , then 'tacking' the bottom piece of borosilicate on top of the string.Once the silicone cures , I yank out the string , voila , perfect gap between outer and inner tank.
The disadvantage to this method , is I have to do 1 piece at a time , but I've got nothin but time so......
Yes, Speedtape: 3M part number 425, actually (another name: 600mph tape). 0.002" Self-adhesive backing, 0.003" thick 2024-O aluminium. The names come from the fact that it's the only tape that can be bonded on an aircraft skin, and that is certified for Flight. Hence the Speedtape and 600mph tape monikers.
1 piece at a time for assembly, and a curing time of 24 hours? You have 2-3 weeks until the pump arrives... take your time!
