Just a little update.
The nuts n bolts have all had a coat of oil blackening and the burner box has been constructed.
I had not realised how much work was in this little firebox.
The top and bottom plates ? not sure what to call them were made by spinning and then adding the extra detail by silver soldering rings into and onto the plates
Just the burner to spin up next then onto the counter shaft.
pic 1 the formers
pic 2 and 3 the toy as is.
Thanks for looking
best wishes

The burner housing and chimney are a work of art!

Someday I would like to give metal spinning a try; do you make your own tools? Would also like to know how you did the joint on the main section of the housing?

A very fine project Frazer.
I really enjoy seeing engines doing something...and this idea is really cool.

Frazer, I can't get the third photo to load, my mobile connection, not your fault. I even drove down the valley to be near the tower, but no luck. I must have tried thirty times.  The spinning is better than an industrial job, but that's one of your fortes. The fire box...what can I say? I guess you just rolled up a tube (a tinsmiths joint?), then milled the slots as per the wooden bolster.

I must say, it worked well!


Cheers, Hugh. All the best for 2015.

Nicolas, you're a gentleman. Many thanks, an important view in my book. The Black Caps did well today! Good on them.

Cheers, Hugh.

Managed to spin up the burner so just 3 screw holes to drill then onto the counter shaft assy :headscratch:

The joint over here as Hugh mentioned is known as a tinsmiths . A handy book is this one

Last post, Iv decided to put it to one side for a while thats once the base is finished
Iv some boats to build and to finish and a Stirling car along the lines of the Lotus 7 wont be as quick but should be fun.
Time for a steam fix
Many thanks for the interest shown
kind regards
