Frame part 4 - rust paint

The pressure gauge is mounted to the top of the level gauge in the original which means that it has to be 'outside' the case. This is an expedient method but personally I find it a little too "steam engine" in an otherwise minimalist design. The advantage of exterior mounting it is that it is much easier to take off as the part that it mates with is fixed. With my mounting method, attaching the copper line directly to the gauge is more of a hassle. OTOH it isn't like you have to take the case off once a day...

I installed the SSR and slapped a coat of rust paint on the frame. This was also a case of expediency as the frame will be powdercoated. I just lost my patience with the rust. Amazing stuff that paint, you could almost put it on with a spoon and it will still level itself out...
