Burrell Traction Engine, Gears Part 5.... And finally the box.

 Gears Part 5.... And finally the Box.


Hello, if you have been following so far, thankyou. I must however apologise for my occasional bad English and grammar. It's easier to drill 80 holes than to talk about it. However we have made it thus far and a pinnacle stage has been reached. The horn plates and shaft tubes have been mated together (THE BOX) and also the bearing housings. This seems like a result because most of the other parts either fix onto this, or are associated with the horn plates.

There are some other holes perhaps required, like the 200 or so dummy rivets, but these are just visual and will be completed when necessary.

The coming weeks I will be considering - 
  • The large gear for the 2nd shaft, as the dividing plate is ready for cutting the teeth.
  • Bronze bearings to go into the bearing housings.
  • The crank shaft. (Or a length of silver steel for alignment). 
  • The eccentrics for mounting on the crank.
  • The steering gear brackets (Small bronze castings I have) + Steering wheel (Aluminium casting).



Also recently I have completed the last few holes on the dividing plate so this plate will do all the Burrell gears and there is no need to get the rotary table out again this year !!.

Also worth spending the extra pennies on decent 8% Cobalt drills, as the outer ring was done using just 1 drill the inner ring I broke a cheap drill, luckily the broken bit fell out. 



Hopefully and fingers crossed, the setup I used for the smaller 2nd shaft gear will also, at a push, just be acceptable to machine the teeth on the larger 2nd shaft gear. We will see, once the blank has been prepared to size in the lathe, and mounted onto the other gear. Otherwise I might have to make a kind of faceplate standoff ring or mini faceplate to hold the large gear.

Short and sweet update, as time is required to do these posts, and as holiday season is approaching progress normally slows a little during summer months.

For now stay safe ...  Make swarf ...  Have Fun.

Stephen.

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 ...
