Burrell Traction Engine, Box Part 1... and stuff

 Box Part 1... and stuff



The 2nd Shaft gear being machined with the mating finished gear for alignment. 


Following the back of the casting now being fully machined, I'm working to a true datum, the previous roughing cuts can be finally machined to size. Using the previous drilled and tapped holes to hold it onto the face plate from behind, this will enable me to machine the inside without fear of catching any bolts or fixings.

This part has been a tricky but well thought out machining process, mainly because of the size of it, and also the need to hold it in a chuck or face plate to make a start on it. 

  
I have also just ordered a Gear shaft Bracket , Part Number 81153 for the Burrell. This will be cast as they do not currently have one in stock but as its not needed right away I have time for it to arrive.






  << Left is the pattern that will be used for this casting, this is from the foundry and most of the parts, I ask for a photo of the bit before ordering, as mistakes sometimes occur when ordering from a part description.


I recently visited  a show and there was a very impressive Black 5 being readied for its turn on the track.  I took a photo, the smell from the coal and the work that had gone into making an engine of this size was very impressive. Occasional visits to shows helps to spur you on, and talking to one of the club members always ends up with an idea or two.






Just a small update on the Solar charge controller I bought to add to my setup for safety reasons.



The ultimate use of this is to charge the battery I use for the blower to raise steam,  similar blower to the one in the photo above but a lot smaller for a 1" Minnie.
   


The latest progress from this evenings in the workshop the 2nd shaft large gear blank is ready for gear cutting. All the detail has been completed on this including the recess for the brake blocks, and the 1/6" offset to allow the teeth clearance against each other.

The next post may be a while as the teeth cutting I know will take many weeks to complete, and then we will be onto the bearings, and hopefully the gear change bracket will be with us in the post.

Until then 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 Show Report 2025

 Welland Steam Show 2025 Report..... (Saturday)    FULL  Video    https://youtu.be/ayib_Q_EvKc Welland Steam Show (Upton-upon-Severn July 25th - 27th  2025). Ross-0n-Wye Steam Engine Society 59th Annual Rally. Hotel : Star Inn also responsible for the "Minge Lane" Music festival. (We attended 1 month earlier). 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 42 miniatures and 105 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 ...
