There is at least one drawback I can see straight away, (apart from the problems of aligning and securing the 5 into a composite whole). The thin walls of the cylinder bore block could easily distort the bore as one approaches finished size.Perhaps a 3 piece assembly by Incorporating the link blocks into the cylinder block.HTHRegardsBob
Chris,Do you have any experience with Sherlines horizontal mill conversion: http://www.sherline.com/6100pg.htmWould that be of any benefit for this project you're thinking about?I've been looking at it for a project I have in mind.Jim
ChrisGlad to see you taking an interest in a Corliss model. I have a couple of ideas about how the cylinder and valve blocks could be created out of 3 blocks of something. If you are working at the limit of machine capacity, doesn't stainless add an unnecessary degree of difficulty? Would you consider cast iron as substitute? I am certainly no expert with silver solder but I think that you could create a multi-part block within the capacity of your machines. I have given thought to a multi part block for other reasons, mostly to enable the drilling of steam passages without the need to go back and fill the access holes. I realized early on that the ability to knit the pieces together would require the ability to silver solder.I have not drawn it up in 3D yet but I can nock something up pretty quickly if you are interested.Jerry
You could scale it down (Jerry Kieffer style) so that it would fit on your mill. http://www.craftsmanshipmuseum.com/Kieffer3.htmDave
ChrisThis is a quick and dirty assembly of 5 pieces. Remember, all those rectangular block Corliss engines are sheet steel covers over a lot insulation. The underlying core looks more like this.Jerry
Can't it be bored with a between centres boring bar then you don't need to worry about a bit lump of metal spinning round.
