Cant drill the hole in the valve chest

106 forum posts 52 photos | Hi all. I'm a long way into my first build of a steam engine - an S-50 - and thoroughly enjoying it, but I've just hit my first issue making the valve chest and wondered if there was an easy solution. The plan calls for a 0.07" hole in the far end of the chest from the rod entry, for the end of the valve rod to ride in (this is incidentally wrongly dimensioned as 0.7" on the plans - I wonder if anyone ever tried that). So the problem - there no way that my 1.8mm drill is going to be long enough to reach through the chest and drill this hole. I could drill it bigger and fit a bush, but is there something simpler I'm missing? Thanks all. |

Gentle heat will get it back out again. A few other options in this article hidden in the depths of the ME site, changing the pdf number will give you all the parts of the article |

106 forum posts 52 photos | Thanks for the ideas and the link to the article. I'm not sure that I'm comfortable with that thin a drill over that distance so I may go with my initial idea of a bush. Thanks all. |
