When Bowman's go BangIn my collection I have a boxed EIOI, which for the last five years has steamed well with no problems. When I last steamed it the steam line on the cylinder end broke off so I asked my good friend if he could repair it. After fixing the problem he tried it on compressed air at a very low pressure to check if it worked. There was a loud pop and alot of yellow rust. On taking the boiler off we found a large hole and lots of rust, plus lumps of metal tubing. The only thing that could rust like this is steel.
Does anyone know if the centre thread that goes through the boiler on the E101 is made of steel?. We think that the steel could of reacted with the brass and weakend it, causing it to fail. I know some Bowman- Wormar engines had steel bottoms, which are found rusted through. My poor E101 is now in bits, awaiting restortaion

Thank god he tried it on compressed air first! Whilst compressed air can give a nasty suprise, and perhaps cause injury, steam can be fatal!
I hope you can get it fixed OK.

Its the rusted rod that goes through the boiler, you'll probably need to replace that!

That is a common fault with the 101.
I had to replace mine as well.
I just bought some stainless steel threaded rod and soldered two nuts on either side of the boiler.
A touch of solder on each end after screwing the rod through and the job's done.

rotten luck that is at least he tried it on compressed air otherwise somebody could have seriously hurt

As already mentioned, the stay rod that runs through the boiler's steel - best replaced with a brass one.
Are you saying the boiler's holed in the bottom? That's a whole different problem!

Yes, sadly when the boiler was tested it cracked and a large section of brass was blown out. The brass around the hole is very weak.
We have a plan however  . We plan to make a copper boiler of near the same size and put this inside the brass boiler. A small section of the old boiler will be cut in the firebox so that the flame heats the copper boiler. The threads for the boiler fittings wil be extended so that they pass through the old boiler to the new.
This should result in the old boiler being on view to keep it looking origanal, whilst the new is hidden

Sounds like a great project....is your 101 boiler of the kind that has a disc soldered in by way of a front endcap? In that case you could just slot your inside boiler in, and the repair should be pretty much invisible.....are you still using the SV and whistle bushes?

very clever

It looks like the end cap is a simple disk soldered in, I will have to clean up the rust first to have a closer look. I can't believe how much rust there is in the boiler, It was every where!!!!
It just show's you can play with steam engines and not know what is happening in the boiler!!
