Burrell Bearings. Finally Something Different

 Burrell Bearings. Finally Something Different..


This month as by way for a change from some of the other long term parts, I have made a start on the bearing material. This was a slab of cast Bronze from the foundry, and I have started the preliminary squaring up and cutting in half, to make 2 smaller manageable but identical pieces. 

Following a study of the drawings, it also has meant the bearing housings have needed additional machining, as they were oversize for the bearings to fit.



Essentially some small corrections are expected, and making parts fit each other correctly is a double check on the drawing accuracy as I'm going along. When both the housings are complete to a width of 1 inch internal size then the bearing shell work can continue.

In other thinking - (and this is an odd side topic) - My Machines.
I have a number of machines, some easier to use, some more accurate and with less run out.  

When rectifying a part, if it could be machined by the Lathe or on a Milling Machine (for example), or  even by hand. The time required to build this engine is considerable, thought should be considered if the right approach is made. Parts can quickly be setup on a lathe, as compared to the more timely setup required for clamping work on the Mill especially if a small holding Jig was initially made.

Essentially I'm talking about parts production speed, machine running costs, risk if part becomes damaged or undersize and machining marks or finishing std when machining the castings.

In future I may pay more attention to this idea, up till now I have been following some of the photos from another web site:-

However by now I have made a good attempt on most of the part to reach the same stage as this fellow builder has, and so there are no more machine setup ideas I can gain from this site. It also appears as if something has happened to this builder, as no more updates have been made since the end of 2011!

But if your just starting like I was, this site is a must!

Also downloading as many photo's as possible is also a good resource, and for that I use the album's on Traction Talk as there are a number of these for this particular engine.

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

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...
