Freelance mill engine from Stuart castings.

I am now making the engine base plate ...it will be made with these strips of 1/8" strip plate and there will be these gusset flanges to get the correct angle to simulate a casting. Also i have found a series of articles by Muncaster that describes a mill engine using the Allen valve gear... however some of his dimensions are slightly different to mine. He also describes the benefits of this type of valve gear for the operator, and this might be of interest to Chris !! these articles are from theModel Engineer   Vol 25  1911.

That base is going to look great, nice way to make it.
The article is good, he has a nice writing style, easy to follow and with practical mixed with the theoretical. Thanks!

The base has now been made and the curved well for the flywheel is next...this needs to be deep enough so as the flywheel won't get clogged up with nuts bolts mugs oilcans etc etc. a cold day to day so stayed in the WKSP !!

I have now been making the raised parts to mount the components on. These plates will be undercut so that a JB weld fillet will attach more firmly... the 'studs' will be bolts screwed up from underneath and secured with nuts to get the correct height. The dynamo is actually on the centre line with the main bearing assy's,which is quite fortunate...

Went to Strumpshaw steam engine rally today and there were quite a few castings and engines The two ST 10's were £200 each , one with the box and paperwork. the 5A was £100 and the other DD one was also £100  There were also other castings that i did not recognise. !! Eye candy for some of us !!.............

£100 for a 5a sounds a bargain

 Is a double diagonal an offset quadruple  ??   I did wonder what DD was ?? nothing to do with the size of the pair !!!

I did wonder what DD was ??

One Lang Bridge Double diagonal and a model of it. Castings sometimes available from Brunel Engineering - it is advisory to collect the castings when you hand over any money

Jo

P.S. Surus has just checked his set of those castings are still safe

That Lang Bridge engine looks to be the one at Bolton steam museum, it's a great day out for anyone in the area.

I started making a very similar V twin last year, I ran into trouble making the cylinders so it is a project still to finish.
