Should this be steel please, or can brass or copper or aluminium be used ?
Thank you
William

Greetings, because of corrosion, I opt for brass, in the larger gauges, rolled up from sheet, easier to work as well.
regards

Steel can be used - it's specified on the drawings of my loco. You get quite a soot/tar/oil build up inside, so it keeps corrosion at bay. Perhaps storage of the loco is relevant - a damp soot/tar/oil might do you no good at all.

There are underground water tubes made of stainless steel, I only became aware of this after receiving my tube from M-Machine metal. It was very bright and so I enquired as to its source.. IIRC my smokebox was machined from a stainless tube 6 1/2 OD with a 1/2 wall thickness. I've now had this for some years in a workshop that can get damp and there is zero sign of any rust forming, even the offcut which hasn't been touched in years is rust free.

I have smokeboxes in aluminium, brass and steel. The steel one hasn't been steamed very often so is no real guide, but at 1/4" thick, I am not too worried about corrosion. The aluminium one was machined out of a piece of very thick wall tubing to about 3/16" thickness. It is now about 40 years old, had many years of steaming and two decades of just sitting around with soot on the inside - and no trace of corrosion. The brass one is, as you would expect, fine.

I'm with Wilf. Steel is fine, provided it's not too thin. On my Stanier, I used steel tube about 1/4" thick, and turned a rim at the front to take the smokebox door ring.  I actually turned the ring and door all as one piece (again of steel) so that when it was open, there was no lip to hamper brushing out any debris. A ring of dummy rivets completed the look.  Just had to make sure it was upright before tightening the dart! |

I like the loco transporter. I've been thinking of something similar for shifting the Britannia from the workshop to the back of the car.

I've got a gravel drive, so the pram wheels were ideal for wheeling across it. Since that photo was taken, I have replaced them with wheel barrow wheels - they're even better. |
