Slowly casting up parts for a steam twin marine engine

Rob, its good to see you are human as well! :) :)

Dean, that IS the main issue and to cater for that I get the pour pretty hot, almost to the point where you can see the zinc start to burn off, (white-ish smoke and residue coming off the melt...), then you get it into the flask fast and have lots of risers cause at that temp you are likley to get sink back, which I did... a pic attached...





I was watching the big riser sink thinking "dont go all the way to the floor....dont..." ..( it didnt..)...

Today I used the flycutter to flatten and pretty the working surfaces... firstly the back of the plate....Johns boot and all...



And the mounting surface....



I added a little putty to a couple of spots.. those areas Ive already discussed as not pleasing me greatly....



and roughly how it will sit... boiler will be up so its top is just under the crank centre line.



No real inclusions to speak of, a good solid cast... machining them up is always the test.. they all look good until you cut open the voids etc..

Cheers all...

Can it really have been so long since I posted on this project???

Just a small update, the engine is still happening, Im just taking a break for a while, its been fairly intense for a long time and I needed to concentrate on other 'stuff' for a bit and also christmas got in the way..   :beer:

Work has been hectic and the office on the coast now requires me for 2 weeks out of every month, so I only have a small window of opportunity from now on. Other projects have gotten in the way as well such as I needed to frshen up the Duke, it was last restored over 10 years ago and the paint was getting a bit tired and I came across a TT style tank for her... a coupel of pics if you are interested....no.. hell this is Madmodder... lets start a thread....

CHeers all
