What if any comercial castings are 7F builders using? If comercial who supplies?

Paul1979 pointed me in the right direction for a few basic castings; wheels, cylinders etc from Nigel Gresley 2-8-0 [Reeves] Abby of this forum cast main horns for me. The big central stretcher in the first pic in this thread was chewed out of a solid bit of brass I had lying around and everything else will be or has been fabricated or machined from bar stock. Tender is easier as there are a few Fowler tenders in 5" gauge, Don Young's Horwich Crab etc. Haven't thought about the chimney or dome yet. Any ideas for that from anyone will be gratefully received !
Ian.

Good point, Paul1979 has a cast dome and chimney bottom on his 7F in one of the pictures, i wonder what he used? Horns say to me silver solder fab in mild steel or mill from the solid steel bar with a ball nose slot drill.

Not very interesting but this is all I've done in recent months.

If you look at the Martin Evans drawings(forget the errors) and the only loco that they apply to is 53807. Small boiler, LH drive & small smokebox saddle. All the original small boilers were RH drive and the other reboilered engines had a packer between the smokebox and saddle.

I am puzzled by Reply 33. There were two batches, 80 to 85, small boiler, RH drive, built at Derby, and 86 to 90, large boiler, LH drive, built by Robert Stephenson and Co. The large boilers were removed over a period of time, but 53807 definitely carried a large boiler in 1951. At that time, there were also two others.
There were a variety of packing pieces used.
NB - this very much the short answer!!

G'day all
A question.
Why did they go to a smaller boiler?
Was it weight = route availability or steaming or other?
Regards Ian

Re reply 35, the real question should be why were the second batch built with larger boilers. As they were built by a contractor, one can assume that they were told to do so. One theory I have heard, but not seen anywhere in print, is that the first batch did not run too well (possibly because of the very short travel valves), so they specified bigger (non standard) boilers on them. As these boilers came to the end of their life, they were replaced by the smaller (standard) one.
Food for thought.

The big boiler was a non standard shortened version of the boiler on Big Bertha the 0-10-0 lickey banker, the small boiler was the std G9AS boiler which IIRC was the same as on the MR compounds. The comment i made earlier about 53807, is that when 87 was reboilered in 1954 the smokebox saddle was in very poor condition and was replaced with a new 1914 pattern saddle so needed no spacer.

A wee bit of progress, just started the tender axleboxes,done the axles and one wheel, that'll be the next thing, progress is still sporadic & deliberate. Spent a few days at Pickering last week and discovered 53809 was running, also discovered that I'd left the digi camera at home so I bought one of those throwaway cameras and took about 39 detail pics of the loco as it stood at Grosmont. Probably handier anyway as I'll actually have them all in print form. Ian. C:\Documents and Settings\Ian\My Documents\Fowler tender.jpg[/img] Attachments:

I had a job finding my own thread about this project, I seemed to have wasted the winter as regards the 7f but I did fit the compensating beams today and made one spring [only another 7 to go] I've cut all the tufnol and spring steel ready for when I've made the other 7 spring buckles with their square holes. My one achievement with this is that I seem to have taken Slow and Deliberate to another level. Ian Attachments:

I did machine the wheels of the tender at some time in the last 6 months, all the springs and brake gear to look forward to on that as well Attachments:

Lovely work.
There's that piano again - how many steam locos is the average piano designed to support? ;D

The tender looks great,very nice work... Springs and brakes... Er yes very time consuming, I've spent most of today just making a jig to hold the brake shoes for machining and still not finished... lol. I need to tackle the springs soon as well, I haven't enough bar stock for the spring hangers to machine from solid so will probably make in two sections and braze together. I notice a nice LNER tender in the background, I'm curious as to gauge and type?.. Pete

This should explain your query Pete.[more pics of the piano too, the 7f just fits on!] modeleng.proboards.com/index.cgi?board=Images&action=display&thread=5274Your own work on the brake gear is encouraging me to get started on it. I did the brake gear for a GWR Hall in 3-1/2" gauge a year or two ago and found it very tedious but as ever very rewarding. I've probably got a pic or 2 somewhere that I'll post. Ian

Thanks for sharing that Ian, she's a beautiful loco and your paintwork looks first class, if I can get my paint looking like that I'll be a very happy man...
