My 7-8n2 critter is getting a roof. More done.

At long last I have started on the roof of my 7/8n2 critter.

I have fabricated the framework in brass strip, rod and tubing soldered together with my regular pcb building iron.

Some of the joints were a bit tricky holding them in place whilst heat was applied to the pre-tinned parts.
My fingers don't like too much heat at the best of times.

I am tossing up whether to use strip wood covered with "tar paper" for the roof or find some suitable brass sheeting.
Any opinions on what to use?

*****************************************************************
August 8th.
Unfortunately the regular K&S brass sheet I was going to use is not wide enough for a one piece roof. So Gordon Watson very kindly cut and rolled some brass sheet for me to fit.
The roof was held in place by wooden clothes pegs whilst I soldered it to the frame one tack joint at a time using my regular fine point sodering iron. I don't have a gas torch. YET!

Once I have the brass thoroughly clean I will spray an etching primer before the top coat of Brown? to match the trucks and end beams.
Then I will fabricate an instrument panel with a clear styrene cover.
Soon I intend to redo the couplers and replace them with Kadees.
I have an idea for a servo driven wire pull for remote uncoupling Kadees.

Nice bit of soldering Tony

How about corrugated iron?

I can roll you some for Saturday if you like....

How about just a 'canvas' tarp. That way all that great structure would show through somewhat.

Why James me lad.
That is right neighbourly of you.

It does need to be fairly robust.

Hi Harvey.
Another good idea. Thank you.

Must look into what I can use.

BTW I took the sound out.
It drove me up the wall because it was not the correct sort.

Great job, Tony.
Just another example of your craftsmanship.
