3" Burrell Traction Engine / Steering Stuff

 3" Burrell Traction Engine / Steering Stuff

     Cutting 3mm steering bracket in the miller.

I think I found a small problem on the Bridport / Plastow 3" Burrell drawings.


The dimension of the steering bearings ID is not right. The chain drum axle is 1/2", but the bearing states 5/8" bore?

However as I was going to make the bearing in mild steel, with a bronze bush pushed in.
Then boring it out 1mm bigger to 16.8mm this means I can have a bronze bush with a 2mm wall thickness and it all looks ok.

I think other people have done this, it seems a waste to swarf off a big bit of bronze for this part.
I found some spare bits of bronze from the front axle that I made wrong so its not going to waste.

Above the steering bracket being cut on the miller, someone commented it was a very versatile machine the Centec 2A, and Its true I do perform a number of different setup/machining operations on the machine.

Sensitive tapping off centre, between centres.

The next item that has been recently ordered is the steering worm and wheel, the price of this came as a bit of a shock at £179, in-fact the price is also due to increase in April. I'm hoping that this doesn't get lost in the post.

* Following day it didn't get lost, and arrived in the post the very next day !!. (bottom left) Yes there's some skill and equipment involved in making these parts.




For the all important Key Steel for the steering worm there is a listing on ebay for this part supplied in carbon steel ready to go.

Until next month stay safe; make swarf; have fun!

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...

Welland Steam Show 2024 Report..

  Welland Steam Show 2024 Report..... Welland Steam Show (Upton-upon-Severn July 26th - 28th  2024). Ross-0n-Wye Steam Engine Society 58th Annual Rally. Hotel : Star Inn also responsible for the "Minge" Music festival details below.  The show as usual was well attended. I'm happy to report the numbers looked fantastic and the weather was as good as needed. Maybe we have inspired the next generation of Model Engineers. It certainly looked like there was no shortage of money changing hands for tools.  The show boasted 37 miniatures and 94 full size engines, along with a huge number of commercials, cars, bikes, tanks and military vehicles and displays. This time again, like last year, there was the heavy haulage arena, which was fascinating to watch, as long as you could keep the coal ash out of your eyes :-) I can imagine the rising fuel costs to move large machines, but this has not stopped them from attending this year. Thank you to all the organisers and engine owne...

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 ...
