3" Burrell motion work Work started a few weeks ago on the weigh-shaft bracket, a tricky casting to deal with. I made a start by centre drilling both ends for the shaft and then made up a difficult setup in the milling machine to try to hold it square for drilling horizontally. This worked to a certain degree, basically the length means any miss alignment is amplified massively but within a reasonable tolerance I completed it. I was then able to turn one end a bit, to stop it looking like an egg. I'm reasonably happy with it, certainly there are probably more out there that look like mine, and maybe some in the bin. I guess if a complete disaster happened it would not be too much trouble to cut the casting up and machine a truly round centre tube and silver solder it back onto the original, to save the day as it not a cheap casting to mess up. The alignment process prior to drilling Often I believe the setup's are as important as the r...
Some non Burrell messing a-bout's In an older time, model glow engines use to career around a pond near me, and lots of fun was to be had running model power boats, on the purpose built lake. In this day and age, all has been spoilt by the noise police, and the impact on the Canadian goose, so they are now free to mess the pool up! As a throw back to the good old days, here is one of my cheapest engines purchased at a car boot sale for £1.50; and successfully ran in a small boat mostly on Sundays. These were taken after some freeing up of the piston, and a quick test run confirms its a animal 20,000 + rpm using old sport 40 fuel. So why? Well one of the reasons why I started to make the traction engine was because I had come to the end of messing about with petrol engines, and the fact that IC engines were also banned. An alternative plan was decided upon, making use of the skills and machines I have. It was just a small distraction in (January 2025) to run one or two ...
