Quicky question: how went the epoxy test?

[BrainEater]

I have not done the epoxy cold test.Since I don't need it anymore , it'll hafta wait till I get dry ice for something else.

Here's how I did the cut . The chopsaw normally looks like this :



I removed the fence and clamp , then bolted the fence into the clamp mount ;



The pipe then got clamped to the fence with a 'c-clamp'..

Found something in my mailbox when I got home from work :






Hehe , Wow ,when you mail something Jean , you don't mess around..24 hours !!

Thanks bud !

I will begin work on the interior glass tank immediately.

Must have been one heck of a cut, with the tubing held in place so far away from the cut section. Lots of bending?

Shipping was only $1.50 more for Express Shipping - it was scheduled to arrive tomorrow... so you can thank Canada Post for the speedy service. And I hope that's enough RTV for your application.

Yea I had to actually hold the blade on the pipe , till it caught.It was sketchy at best.Wrong tool.

I've done some steelwork.

Top marked : The bullseyes are the threadmounts from the tank top , the red bits on the edge are where I need to grind off material......



The secondary mitre cuts on the tank vent lines are done :



Setup for final marks , weld points :

Do I see Speedtape? Heck it is! That's Speedtape! Damn, you only use some of the best stuff...

[yycraven]

At first I did not think it was speed tape, but your right it is speed tape I have a few rolls of that..lol

[BrainEater]

Speedtape eh ?

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......

[3.0charlie]

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!

[BrainEater]

Cool !

I've never heard that before....hehe

--------

Did some work.

Here's the vent connections sized and welded ;



Rough finished (it'll probably stay this way)



----------

I'll probably spend several hours working tomorrow too , so I should have more pics right away.

By the way, a 2" wide x 60yd tape roll costs 50$... so use sparingly!

I used to love welding; unfortunately, I haven't touched any equipment in years. TIG weld?
