Big end bearing part 3

The big end bearing has taken a while to reach this stage, but it’s finally starting to come together. The remaining tasks are fairly straightforward now—just making the taper wedge pin and shortening the con rod to its final length. It’s been a really satisfying piece to produce, and I’m very pleased with the results so far.

As mentioned earlier, the original bronze casting was huge compared to the finished part, so a significant amount of material had to be removed. In fact, entire sections were sawn off just to avoid generating excessive swarf. The bolting pins were made from 2mm silver steel, with threads added simple enough work.

Until next time, stay safe in the workshop, make plenty of swarf, and keep building!

Midlands Model Engineer Show 2024 - Warwick

Midlands Model Engineer Show 2024 - Warwick This year’s Model Engineers Show 2024 was a huge success! All four days of the show were fantastic with exhibitors and visitors alike enjoying plenty of opportunities to purchase items, learn and explore the very latest in machinery tools and model engineering. The 2 exhibition halls were abuzz with vibrancy, excitement and anticipation. I went with a usual shopping list, and a few parts that I had organised from suppliers to take to the show for me for collection and postage saving opportunity. I ordered an expansion Link and had it water jet cut this being the results after only minimal cleaning up required. I reamed the holes out and basically park this until the rods are done. Back to the show report. There were some fantastic models on display and also the gas turbine demonstrations running outside along with the traction engines and a few helicopters in the main carpark. Below the pictures I took on the day and a few videos of the ...

1" Minnie Traction Engine By Stephen Meredith Background Working Progress (Gears) Front End Parts Following the completion of a small marine steam engine "Trojan Engine", I decided to tackle a larger project. Having visited various shows and the model engineers Exhibition, I decided to buy the Construction book for building the popular 1" scale 'Minnie' traction engine. The initial workshop experience was limited but keen to learn, and research has enabled me to get it this far. A s can be seen, this is basically finished well almost, it steams, and runs well a few tweaks are needed but tweaks don’t make piles of swarf. The intention was to show the engine and run it, at rallies but what I really wanted was a capable engine that could pull an adult or (me) on a field. This engine was, therefore, a stepping stone to be able to tackle the engine I wanted. After research, I bought a set of drawings for the Plastow 3” Bur...
