Looks great!


If I understand correctly, the hotwell would have some level of water that the exhaust steam goes into, to be condensed and pumped out? Was this so the water could be recycled back into the boiler?

Hi, the Hotwell name is a bit of misnomer as the water in it is cold, usually from a river /stream and it actually is squirted into the condenser, hence the name jet condenser. this water mixes with the steam fr m the cylinders and is pumped by the air pump into the `boiler feed pump container and any excess is returned to the river/ stream  This engine is quite crude as there seems to be no provision for cylinder lubrication with an oil supply or any water /oil separator ?? perhaps the low pressure  unsuperheated steam was used as the "lubricant" !!

An air pump pumps the condensate out of a condenser into a hotwell.  From there it may be pumped into the boiler. The main reason for having a condenser is to provide a vacuum (except at sea, where fresh water for the boiler is more important).

Yes ,also ,they only used jet condensers where they had unlimited supplies of fresh water from a river so they would not have to pay vast sums of money to the local water board. There are lots of different configurations for these air pumps, hotwells, condensers ,et al and at this time there was still lots of experimentation going on. Also the water in the air pump tank does become warm and this goes to make the boiler feed water less cold so more efficient  as regards fuel consumption.

I have now finished the codeser/air pump housing and connected it up to the base plate. there is hardly any room inside their box to work on any of the inside components, so the jet condenser valve and water level and drain cocks may be for show only.  The boiler feed pump is the next part to make...

 Yes you are right, but, most of it is rusty, dusty, very wet and relatively incomprehensibly !! here are some pics of the sister/brother engine at the Ramm brewery that is quite moist !! ;D ;D also next to the hotwell is the foot well and also a mention of the hotwell as in steam boats....

That one curved pipe looks like there was an "uh-oh, now what" moment as they were assembling it!


And now you need to model the feet in that footwell!
