Small Boiler

The differential has taken some time to get to even operate. However, after making some shims to space the crown wheels correctly I have something that operates.

I might still re-make this, but for now I know I can get something that works as a differential. In practice it will not actually see that much work and so it is probably ok.

I thought this little differential warranted a bit more of a video around it's assembly, the shims and me "running it in" at a stupid speed....

Just machined a solid phosphor bronze rear axle for the Burrell. OK, this isn’t a solid rear axle like a 1960’s muscle car. This is an actual solid round phosphor bronze bar that supports both rear wheels to rotate independently and then the differential sits on a separate layshaft.



and then just so that you get an idea of the scale

Wow! impressive work!

Just been silver soldering the parts for the rear hub caps and thought I would share the process of using easy flo paste, very easy to get great results on small parts

I've had a bit of a break from building this, however, in the last few days I've sorted the rear axle and the rear hub caps. Now I think it is taking shape. On my latest status page of the Burrell Traction Engine there are even more images.

Finally the Burrell is back on the workbench and I've made the connecting rod from 3 parts

Here with the phosphor bronze big end in place. Hopefully the matchstick gives you an idea of scale.


The conrod was assembled from 3 parts

Spent a few hours making the eccentric pushrods and then testing them on a drill:



The two eccentrics gives the ability to run the steam engine in forward and reverse. I need to make up the slider, crank and handle etc

They need a bit more fettling and finishing of the eccentric pushrods, but I'm happy for now.

The differential sits on the layshaft and this takes a bit of thinking about. Hopefully the following image helps.



The drive and neutral is achieved by sliding the crankshaft gear out of mesh.

Lots more to do, but gradually getting closer to completion.
