you sure you haven't got a complete set of parts hiding under your bench Alan?? at this rate you'll be finished before me....  the bogie looks first class sir.....lovely piece of engineering Pete Well I did tell you lads that this has been a "Back-Burner" project covering so 20 years now and naturally I've accumulated quite a few items from one source or another ( eg-- the original cylinder castings were those destined for the ill-fated Castle group-build....Later, I could afford to buy all brand-new from Polly, and those are the ones part-machined by J D Engineering for me...I'll finish them when the Warco mill arrives in April 2015..)..........................................................The bogie was bought from one of the "Castle" group lads then stripped and fully re-engineered by myself...You'll notice that the axleboxes still have the masking tape on with their various sizes written down.....Similarly, the fit of each box into its' parent horns varied from a 5 thou interference to a 15 thou ( That's 1/64" ) clearance !!.....The lateral springing didn't work and the pivot pin was too tight..........And it was all covered in a brush-applied black enamel paint ---Ugh !!.......So I shot-blasted it ( care of HM Gov. "Tanks-R-Us" Ltd.)....then fully stripped, re-engineered the faults and it's now almost ready for re-building and re-spraying...This is almost like a Heritage Railway restoration, only in 5"gauge and it's just as damn hard work too........Identifying then repairing other peoples faults etc. plus upgrading the whole overall finish to GWR standards is no easy thing........Sometimes I'll opt to build a new item outright ( most of the Bear's tender is thus--) or scrap a bought-in item and copy its' dimensions within a new part if I can't get the drawings at that time, again, very much in line with full size restoration thinking.................... But I love doing it this way as it gives all my Engineering knowledge a good work-out PLUS}-- introduces me to new ones along the way..A very good and useful example being laser cutting, especially where it involves mass quantity and repetitive shaped items..The running board support brackets for instance.................oops, too much ratchet jawing again.......Alan R..PS}-- These days I don't build new boilers as such ( but will do minor repairs then Hydraulic test etc.).. The Bear's boiler is a joint design effort between Mr. John Ellis ( Ellis Boilers) and myself....I did all the initial research and design work ( this alone covered a 3 year period ) .. which I asked John to check for basic design compliance from time to time....This he did plus suggesting some design changes along the way ( The short combustion chamber)...........He also took the build contract and we anticipate it's completion some time during the Summer of 2015.......I've also asked him to keep a photographic record of its'construction so look forward to posting them on here.......Would you like that ?? |

Well, it's good to see the project coming back to life. I'm surprised the 'back burner' didn't run out of fuel.  |

It did !!------ the Divorce Courts and subsequent Maintenance Payments ( including those little "Upgrades" each time she was expecting one of his kids)..saw off any disposable income back in those days....That's why it took at least 20 years ( Just in case Daughter carried on with Further Education after age 19, when normal maintenance payments ceased ..).......Oh yes, running parallel at the time was the Mortgage Rate at 15%.........The Miners Strike...........Poll Tax riots......The £ falling against the $..........and Spitting Image !!.......Happy days indeed........but thanks for the smiley !!

Hi guys------- Just a little bit of de-painting on the Bear's chimney to-day..................... Can anyone spot what's wrong if I fit this once it's been painted ??.................  |

Very neat little parts, I have no idea what they're used for though.

Ah, that's what they're for. I'll probably machine something out of solid with a flat back.

What is wrong with the chimney then,dont say it was the only GWR loco to have a brass one........

I'll probably machine something out of solid with a flat back. ----I think most clubs now requite solid bar couplers between engine and passenger trucks...I'm not sure as to them being of a "Safety Compliant Rating" nature yet though...........Here's one of my 0-4-0T locos fitted with a more simple type of bracket ( found at HM Tanks-R-Us Ltd..).>>>>>>>>>>>>>>>>>>>>>>>>>>>>  |

Whilst obviously a necessity, they don't half spoil the look of the back of a loco!
I think I'll definitely need to come up with something that can be removed easily and won't damage paintwork.

My thoughts entirely. Maybe something that has a deep slot in it so that it goes under the buffer and uses fixings behind it to hold it in place? I'm not keen on drilling holes in the buffer unless it's absolutely necessary. |

Cheers Alan, and best of the season to you and yours ... Perhaps I'll raise a cyber glass of Old Peculiar to you on the day.

OK, I just thought I'd pop this one in.. Roger, it's those kit of laser-cut parts you saw earlier on >>>>>>>>>>>>  |

and while we're at it here's the chimney.... I need to dress-up the join line area...The trouble was that there isn't much by way of a good definition in the machining.. Maybe mount it on a mandrel in the lathe and a light skim over the lower part might improve things ?? >>>>>>>>>>>>>>>>  |
