6100 Royal Scot..Progress 2010/2011/2012

Re: 6100 Royal Scot..Progress 2010.

I take on board some of your comments but if the enthusiast (the very same people, the HLF are trying to keep happy) are bickering at every twist and turn is it hardly going to encourage the HLF to support future projects.
Lets just be thankful that 6100 will soon be back in steam for us all to enjoy and hopefully support.

I take it Chris you are a member of a grant giving body then? If you are not then please do not speculate in such a manner.

 

Re: 6100 Royal Scot..Progress 2010.

Agreed - the thread is actually entitled 6100 Royal Scot..Progress 2010 and presumably 2011!

 

Re: 6100 Royal Scot..Progress 2010.

Even if the HLF havent become more wary of supporting big overhauls, i cant see it hurting if people thought they were and so made an extra effort to address the quality control and project management issues that have allegedly afflicted 6100.

Great at last we have some folk that see sense, lets keep it what is happening in 2011

Not progress really, but the left cylinder was still sans piston at Crewe yesterday.

Re: 6100 Royal Scot..Progress 2010.

must have been stored in the open as the paint seems to have gone orange!

 

Re: 6100 Royal Scot..Progress 2010.

It could just be the photo, or my eyes, but is there something dodgy about the surface of the bore towards the rear of that cylinder?

 

Re: 6100 Royal Scot..Progress 2010.

Could be some surface rust where there is no oil.

Re: 6100 Royal Scot..Progress 2010.

I would be concerned that this shows a scored liner.

 

Re: 6100 Royal Scot..Progress 2010.

I wouldn't call it dodgy. Only looks like surface rust but it could do with a wipe over with an oily rag to stop it getting worse.

 

Re: 6100 Royal Scot..Progress 2010.

without actually looking at it, its hard to tell if its surface rust or if its been damaged, could this be a side effect from running it when the wheelsets were out of true? but looking at the picture i would expect that the liner will probally need a rebore to clean the rust marks out as even small ridges left by rust could cause a ring to pick up and score the bore

 

Re: 6100 Royal Scot..Progress 2010.

It's just surface rust by the look of it. Nothing that a bit of emery cloth and an oily rag can't sort out.

 

Re: 6100 Royal Scot..Progress 2010.

Thanks for the picture Graham is the cylinderallways left exposed like that?

 

Re: 6100 Royal Scot..Progress 2010.

looks like rust to me too. same colour and texture as the stuff at the end of the cylinder. As people have said, just rub an oily rag down it a few times, or just let the piston do rub it off once its back in (if that's mechanically allowed)

 

Re: 6100 Royal Scot..Progress 2010.

Oil is no way of preventing rust as it absorbs water. A proper rust preventative should be used and one that will not run from the top of the liner and settle in the bottom thereby exposing the top of the liner. I have always been dismayed by the way a lot of railway relics are stored outdoors with little regard to the elements. A few pounds and time can save an awful lot of work and expense in the future.

 

Re: 6100 Royal Scot..Progress 2010.

When putting machined surfaces outside for store I have always used water pump grease spread (a Castrol product) over the surface and then covered with a tarpaulin sheet. Even after 5 years outside once cleaned off the surfaces have come back to their original condition. We did try a spray on type wax compund but it was a b.. to get off again and penetrated joints that then needed a total strip down. But this was on machine tools, presses and press tooling so maybe not relevant to locomotives.

 

Re: 6100 Royal Scot..Progress 2010.

If oil aborbs water then the lubricant industry has a big problem. Almost all crude oil and synthetically derived oils are hydrophobic and will not absorb water, they form the basis of most water shedding products like WD40 and various clones. Similarly they usually form the basis of most greases and corrosion protection compounds. With greases they are thickened variously with gelants such as bentonite type clays and filled out with inert materials such as fumed silica, china clay, lithapone etc. With anti-corrosive products the oils are modified with various hydrophoblic surfactants and in some case waxes if a non-greasey set film is required for easy handling.
Agreed oil on its own is often insufficient for long term corrosion protection, but is better than nothing and sometimes preferable in the short term. I am an industrial chemist by trade and have worked in lubricants as well as many other areas in my time. Hope this helps, thanks.
