Replacement plate to fill this gap was having weld bevel applied today.

Any idea what the condition of the boiler was? I take it like the rest of the engine, t'was in need of a thorough overhaul.

How many 43106 threads do we need? This is at least the 3rd one...

The boiler was in a similar state to the rest of the engine. I think that you could safely say the it's having the mother of all boiler repairs - including a complete new section of boiler barrel. Boldford may be able to help with the full list of surgery.

Adrian.

I thought 5110 had the mother of all boiler repairs, or has 43106ís surpassed that accolade now. Shocked

Sorry Ade. I'll be the scapegoat and take the blame for starting a new thread unnecessarily. Embarassed

Right: Here goes; with appologies if I've missed anything.

New front boiler ring. (As reported by Adrian).
New smokebox tubeplate.
New outer doorplate.
New outer wrapper half sides.
New lower portion of throatplate. (Just visible in the picture above).
Several new copper laps to the inner firebox.
Welding up studs holes on Cu tubeplate to allow rivets to be fitted.
Plus the usual humdrum stuff like stays, repairs to cracks in the foundation ring. etc. etc.
On this occasion no welding required to remove grooving just above the foundation ring. (Because its all new material).

All in all, some serious money!

P.S. Before anyone moans this isn't contract work and the information did not come from the WMNL.

This is probably a silly question, but would a new boiler cost more than the repairs stated above, taking into account the cost of the labour involved? I know that the whole point is to PRESERVE the locomotive, but at what point does a repair become uneconomic, over replacement? (boiler only, not the whole locomotive)

A comment on the 82045 website was that they'd [some time ago] been indicated £300,000 for a new untubed boiler. Steel prices have risen.

I know that the Germans [can't spell Meningheim or whatever it is] are reputed to be putting out feelers for a batch or batches of similar boilers, using the experience they've gained on Tornado.

All from memory

The original axe but on its 3rd head and 4th handle. Laughing

Not a silly question at all. Whilst this is a pretty big repair, even by our standards, you must consider all of the parts that have been replaced would have had to been made and assembled for a new one; plus many many other parts. If you get a chance to see the boiler whilst its under repair think not so much about how much has been replaced but more how much has been retained. Think about the cost of a new inner firebox. A big chunk of Cu! Just think how little, in percentage terms, of that big chunk is still in good shape and will see out most of the posters here.

I'd be inclined to wait a while to see how the all steel welded boiler performs under heritage operating conditions.

Presumably you mean heating and cooling cycles, mick?

That surely is down to the care taken with warming up and cooling down, should take a couple of days? Rather than a few hours.

I am sure the boilermakers will have told the A1 people how to manage their new boiler.

...Well one hopes so.

I'm concerned about a couple of matters.
There isn't a great deal of experience of all welded boilers in the UK.
Will the A1 people heed the advice given?

Reading the engine notes in the last mag regarding availability of copper, I guess that steel will become more common?

Thinks, aren't the Bulleid pacifics' boilers all welded steel?

Only part welded I think you'll find. http://en.wikipedia.org/wiki/Oliver_Bulleid
