Machining a Stuart 10V Steam Engine.  Harold Hall

Workshop Projects

Having noticed a viewer had arrived at my web site by searching  for “Stuart 10V”, I went to the Google page to see where I was in the ranking.  Whilst there, I visited a metalworking forum that was listed and found the subject being raised was making a Stuart 10V in a workshop having just a lathe.  


The brief articles that had appeared in the Model Engineer at that time to illustrate machining processes,  using some parts from a Stuart engine, were though using both a lathe and a milling machine. This being the catalyst for the comment on the forum, a comment that a number of others agreed with. The train of thought was that an article for the lathe only workshop would be a good idea and if produced should be at a level to suit the novice metalworker.


Having around 15 years previously made a 10V using just a Hobbymat MD65 lathe  and a small drilling machine I suggested to the editor that I could possibly satisfy the forum members wishes, and no doubt others, by producing a series to cover the subject in that way. It was agreed that I do this and that it should have sufficient detail for those with limited workshop experience, I expect though that the more experienced will find some of the processes different to those that they would use and therefore these pages are worth studying for them also.


Lathe with milling machine

Whilst these pages are based on a machine shop without a milling machine very much of what is suggested is also applicable even if a milling machine is available.

I consider that the viewer having a milling machine will have little problem with transferring a small number of the operations from the lathe to the milling machine. Even with that done much of what is suggested for the part if machined on the lathe will still be applicable on the milling machine. The workshop owner having a milling machine should not therefore assume that this is not for him, or her.


Lathe without milling machine.

Photograph 1 shows both engines that I made using the method, with the 10V shown individually in Photograph 2 and the 10H Photograph 3. The initial pages are though based on the 10V but then concludes by showing how to machine the few components that are different in the case of the 10H.  Stuart have kept the part names and numbers the same for the two engines so those I use will be applicable to both.

If you are experienced in the use of the lathe then you can bypass these early pages and go straight to “Construction Commences”, page 4, where the photographs start.


Others may also like to do that and then come back to the earlier pages later.


PAGE NUMBERS. Being a long feature it is unlikely you will read it at one sitting. Note the page number at which you stop and next time use the links above  to start where you left off.
