Mamod MM1 burner repair

The meths burner on my Mamod MM1 had a leak, on the tube between the reservoir and the wick tube. This joining tube had a split along its top, allowing meths to leak out and burn, messing up the paint on the baseplate.

The first step was to clean up the tube, and stuff the reservoir and wick tube with wet toilet tissue to act as a heatsink;

Then, using a small chef's/jewellery size blowtorch, Powerflow flux and soft solder I repaired the seam; 

It took me a few attempts to get the solder to flow as I wanted it to, and the result isn't at all pretty, but the job is done. To test for leaks I filled it with meths and left it on some kitchen roll, the paper stayed dry showing that the repair is good. So, I filled the boiler and tested it out properly;

Note the blowtorch in the background.

Here it is again with my little S.E.L. saw;

And with some Wilesco lineshafting;

And finally, driving a rather neat and fun Wilesco power hacksaw;

This type of repair work is new to me, I've never used soft solder before or soldered with a blowtorch. The burner now needs a fresh coat of paint, and I'll repaint the firebox and baseplate as well, but not until the weather warms up again.
