Tsk, tsk. Poor show Andrew, you didn't repair the damage to the cover :lol:

A friend wanted me to drill it and put eye bolts in, until I pointed out that it had key slots and eye bolts would be a dreadful trip hazard!

And no, I didn't weld up the bite out of it - it's been bad enough welding that heavy galvanised box section with all the popping and spluttering and porosity that it gives without trying malleable iron !

How long does that bitumastic paint take to fully cure? Is there a risk it will just glue the cover into the frame?

It was touch dry in less than an hour. It has a reputation of being hard to brush, so I left it in a bowl of hot water for an hour before I opened the tin. In fact it was no problem as quite fluid but I suppose it probably can be a bitch in cold weather.

This morning I cut a 750 mm square 'bottom shelf' (with notches to accommodate the verticals) out of 6 mm plate on the CNC Plasma table.

Why as heavy as 6 mm :scratch: Two reasons - A/ I had a handy bit and B/ 6 mm is thick enough to drill and tap and not have to bother with nuts in hard to locate places.

This allowed me to do a 'dry fit' of the tank and pump, and (although not in the picture below) also the huge heat exchanger balanced on a plank on the middle rails. This was to better let me work out pipe runs and place yet another big plumbing bits order :bugeye:

The issue that I have now is that one side of the heat exchanger is male BSP, but the other is a 54 mm stainless steel socket intended for soldering in copper pipe. Now it is a massive heat load to solder, and I'm not sure what solder and flux you'd use with those metals - any suggestions welcome.

I rang the manufacturer of the heat exchanger for advice and I'm waiting for their technical people to get back to me but I expect that's not going to happen any time soon :(

I also asked what the price was of that model - £500 plus - glad I got them on ebay not off the shelf :clap:
