"JOHN" the Burrell Traction engine "JOHN" being my Dad's name, and the inspiration for the whole Model Engineer hobby. From an early age we often attended the Model Engineers show both in Birmingham (Bingley Hall) and Ally Pally London. Model boating was his passion, and scratch building 4 stroke petrol engines a key activity. This involves a lot of workshop equipment, so when Raleigh the bike people when finished in Birmingham my Dad purchased a good selection of the machines from the old tool room. As a tool maker, and draughtsman by trade he knew when a machines was fit for purpose, and if an improvement or rebuild was necessary. I have continued the tradition and of course use the same machines, and have made a few improvements to them myself. So its Fitting that the new engine bears his name, my previous engine a 1" Minnie called "NINA" after my wife which he did get to see running all be it on air, not steam. The plate just requ

I'm prepared to allow it to wear in (a bit) as I have been machining it by 0.1mm at a time, and have removed and test fitted it many time. The photo (right) is almost there, but not quite, and some scraping with a HSS tool in the corners has been done to achieve a dead square corner. Finally!!, Last night it fitted and revolved smooth, however after the application of some 3-in-1 Oil It did go a little tighter. I can only imagine the oil was sealing the parts together, as they are a really close fit, but after some more scraping in, and using a blue marker pen, to see the wear marks show its finally complete. It just remains to complete another 2 to the same standard, and hopefully it should be quicker this time. The main problem was the inability to measu
