 axleboxes,wheels and axles finished |
Wheels, axle boxes and axle's are finished and ready for quartering.
The axle boxes have been fitted with oil nipples which when piped up
will be fed from the cab, I have drilled oilways in the boxes so as to
ensure good lubrication. It's important to keep these boxes well
lubricated as on a previous Romulus build I had a seized box while
running at Hemsby some year's ago. |

I use steel pegs on the boxes for locating the springs and keeping them aligned with the upper spring locating pegs,I find that if you do not have some positive anchor points the springs can move out of position when running |

 Smokebox Sadle  |
While the smokebox door ring pattern is at the foundry and chimney base,both awaiting casting I thought I would fabricate the smokebox saddle. To make a pattern would be a simple matter, but for a change I thought I would build one up out of plate and bar, The whole lot was then brazed up with the Sievert torch, pickled in sulphuric acid then well cleaned up and a bit of car filler spread in the corners to simulate a casting which I think it does well, it will look better after painting. |

A lot of people shy away from patter making but it can be a a very interesting pastime and can save you pound's, The only trouble is, locating a local foundry which are prepared to cast one off casting's, jobbing foundries are getting scarce these day's, so it's a matter of looking around your area or looking in the yellow page's. The important thing to remember when making pattern's is to make sure your pattern has enough "draft" for the moulder to remove the pattern cleanly when moulding, what this means is that you need to leave a small amount of taper on the various edges of the pattern so it will leave the moulding sand clean without dragging the sides of the mould. Also if you require a bore to be cast in your pattern you must make a core print which is usually painted black, while the rest of the pattern is painted a red colour, so the moulder knows which is solid and which is hollow, very important.
