Hi,
I'm a newbie and have been lurking around in here for a while. I find the information very relevant and helpful in here.
I'm in the process of having a go at building Elmers Beam Engine No.24 and have a question about the cylinder ports. I suppose this relates to all cylinder construction.
In Elmers plan it calls for two #60 inlet/outlet steam ports and a couple of other holes which go through the steam chest and some also through into the cylinder. The #60 holes are then plugged on the outside edge of the steam chest.
In a cylinder construction should these holes be done before or after boring the cylinder and steam chest? I can see positives for each way. Doing it before is likely to cause the drill to wander. Doing it after it's likely to burr the bores, break drills and the posibility of solder weeping into the steam chest bore.
