John I have a couple of comments 1. The pump does not need to make the vacuum. That comes from the change in volume as steam condenses into water. It just...
Hi Paul, Well, it depends how you look at it...the condenser will start out full of air, the pump has to get rid of that. I suppose if you went though a drill...
The tradtional method of finding an air leak (vacuum leak) in a condenser is to "candle" the condenser. That is done by taking a lit candle and going over or...
Another old time Boston Yankee method of finding air leaks was to put a half pint of grog mixed with molasses in the feedwater. Then just wait and see where...

Hi Paul, Yes, I am well aware of collapsing tins in that way. On the other hand you can also collapse tins by connecting them to a good vacuum pump, and I have...
HI Chris, Yes, I think so long as the seal is good then it is not going to matter too much what is used. Although so far with mine the leather is best. (The...

Hi everyone, I'm wondering if anyone has a good solution to a little problem I have. The old single cylinder engine on Zeltic is a bit worn, and has developed...
Daniel, Trial and error is probably the best way. Use cigarette paper as a shim. It is about 0.001" in thickness. Once you have the required thickness change...
Hi Daniel, Bear in mind that it is a steam engine so will be reasonably tolerant of small errors. I don't think it is going to matter if the crank is ten or ...
Thanks John (and Paul for your earlier note).  I did try to bring the shaft down in the front bearing, removing a shim between the shells in the process....
Dear Daniel, When I set up my engine for the first time I used a large builder's square sitting on the lower half of the main bearings up against the piston...
Hi Daniel You might try plastiguage for your bearing measurements. It is available at most well stocked automotive stores. For a small engine somewhere between...
To make sure the crank is at right angles to the cylinders or frame see if you can use that therom we learned in high school geometery. That is a 3-4-5...
Thanks John and Chris for your ideas. What I did was to set a straight edge along the bearings, and then put a square on top of that, while checking the...
