Correct.

CTL Seal tell me that the pipe in the April 1 photo was for a piling job. Another company had made up the pipes, CTL Seal's job was to weld them together

Don't forget the Open Day next Saturday!

Back onto Roller bearings here a snippet from from Impossible dream Part 2 ( Duke of Gloucester) Unfortunately the OCR software has translated it into 'Northern Irish'
"...preporotion for exomining the roller beorings put
in hond. Initiolly o representative somple of the wheelsets wos dropped
ot the request of Poul Eoson, ServiceEngineer for British Timken -- two of
the solid connonbox beoring type onthe locomotive ond one outside beor-

ing type on the tender. The work wos hord ond time-consuming, but the
newly-commissioned wheeldrop ot Didcot did its job perfectly in the skilled
honds of GWS engineers. All of the beorings on the three
wheelsets were found to be in perfect condition, but Poul Eoson took somples
of greose from oll the other beorings, for loboratory exominotion ond
subsequently osked for the dropping of the troiling truck wheelset of the
engine. Inspection in this cose reveoled corrosion pitting in the toper rollers,
probobly coused by ingress of woter through defective reor seols, ond Poul
directed thot they be chonged. British Timken supplied o portoble pump to
pull off the old beorings ond Poul personolly fltted the new ones."

 

What’s the date of this work plse?

 

It would appear to be around 1989. I thought you might prefer a more readable copy!

The result was that the boiler was not ready for hydraulic test until the beginning of October, and all hopes of having The Duke in traffic for at least part of the 1989 season had come to nothing. While waiting for the tubes, the mechanical parts and valve gear had been re-assembled and preparation for examining the roller bearings put in hand. Initially a representative sample of the wheelsets was dropped at the request of Paul Eason, Service Engineer for British Timken -two of the solid cannonbox bearing type on the locomotive and one outside bearing type on the tender. The work was hard and time consuming but the newly commissioned wheeldrop at Didcot did its job perfectly in the skilled hands of GWS engineers.

All of the bearings on the three wheelsets were found to be in perfect condition, but Paul Eason took samples of grease from all the other bearings, for laboratory examination and subsequently asked for the dropping of the trailing truck wheelset of the engine. Inspection in this case revealed corrosion pitting in the taper rollers, probably caused by ingress of water through defective rear seals, and Paul directed that they be changed. British Timken supplied a portable pump to pull off the old bearings and Paul personally fitted the new ones.

This makes me thonk of Officer Crabtree... "Good Moaning". .

Good to see the progress of this exciting project.

 

Yes, things are starting to happen. The frames should be lifted onto the stretchers today. CTL Seal now have a time lapse camera operating so I aim to get some pictures off it on 20 May. Geoff, Keith and I are going to visit our cylinder pattern maker in Scotland next week. He's taking us on a visit to the foundry in Bo'ness to have a discussion on the Tuesday. We should be able to come up with a timetable - the intention is that the cylinders will be cast next year.

 

More progress!

We are aiming to get some better quality photos on Monday

Absoloutely itching to get at the exhaust steam ports with a mini grinder/polisher !

 

Ha ha. Last time I did that was on my Moggy Minor c. 1972

 

Exhaust steam on a Moggy? That's brought a memory to the surface as I once had to perform a heater bypass operation on Clapham Common on my MG Midget, during a Friday evening rush hour. Great fun .... not!

..... but seriously ..... assembling frames is such a very significant milestone and it's great to see so much solid progress on 72010, which I'd reckon pushes perception of the project from an 'if' to a firm 'when'.

 

I dunno, it's definitely been a 'when' in my mind for a long time now.

Noel

 

Well she used to blow head gaskets pretty regularly until I had the head skimmed

 

In my mind too Noel. P'rhaps I should clarify .... what I meant (and failed!) to convey was how the project is perceived by anyone who hasn't been following the remarkable progress since the new team took charge. The question of when any newbuild crosses that hard to define line and comes to be regarded as 'meaning business' is one I've banged on about before, but, in anyone's books, assembling frames certainly has to be seen as highly significant.

Been there too! Always preferred Leyland models to Ford .... 'cos you could get at the big ends without taking the whole engine block out .... other than the Mini, at any rate. S'pose most folks would prefer sommat not knackered enough to need such TLC in the first place. My old MG was the last major engine rebuild I did (the heater incident convinced me I couldn't put it off any longer) ..... with modern IC cars, I wouldn't know where to start .... anyhoo .... I'm far too clapped out to roll around between axle stands these days!

 

Chris has been into CTL Seal today and has taken some better pictures. Here's another one for you. Geoff, Keith and I are in Scotland this week talking to Tony Dance about the cylinder pattern. Once the motion and valve cylinder patterns have been made Tony will need to start on the complicated bits to produce the "cores" that create the holes in the casting and the "prints" that will hold them in the right place. Keith will need to prepare drawings from the 3D CAD model to help Tony. So this is a good time for them to get their heads together so Keith knows exactly what Tony needs. Tomorrow we're off on a visit to the foundry so we can discuss the pattern with them.

 

The frames look very impressive when compared with a couple of people alongside them. Here's Geoff and Tom alongside. The smokebox saddle will have to come out for a bit of machining. The shoulder that sits on top of the frame plates is not quite at the right angle (the saddle like the cylinders sits at a slight angle to the vertical) which should be fairly simple to rectify. Everything else is lining up well and CTL Seal are going to make up some more dowels to locate parts. The frames are currently shimmed so they are 6mm too far apart. This will allow CTL Seal to drop in 3 of the 4 flanged horizontal frame stretchers. The front one will only go in after hornguide machining

 

Excellent Ian. At what point do the rear frame extensions get added please?

 

Basically with the frame extensions in place, the assembly is too long for the machining station where the hornguides and frame keeps will be machined. So we still have to fit the trailing feet for the rearmost frame keep attachment point prior to machining. Geoff has had a couple of plates made up, slightly over thick, which will be bolted between the trailing feet and the frame plates, as spacer plates in lieu of the frame extensions. After machining we'll remove these temporary plates and fit the frame extensions. The assembly will have to be rotated through 90 degrees after machining so it faces down the shop as it will block the assembly shop otherwise!
