Does anyone have a drawing for such an item suitable for a 5" Pansy. I believe they seal very well?

I have used loctite bearing retainer with great results. Its extremely viscuos and not too hard to undo. Its especially good for sealing around water gauge glass if the fit is less than perfect. Its yellow, smells sweet and tastes awful!

this is the end of Sunday - most plates roughly cut to size with the plasma disc. I even labelled them up! Will keep you posted if interested - any questuins, please ask.

almost finished these two - individually marked out and drilled and very close! 12 holes 7/16 and 4 @ 1/2. The two outermost were supposed to be 3/4 for superheaters but thats a bit ambitious me thinks! The right hand stay hole has now been redrilled and tapped to take a brass ferrule which has an internal thread of 1/4 x 40 tpi for the blast steam transfer.

all drawn to scale on Visio so I can take measurements from drawing, and separate cutting profile for each part drawn - cut out - spray glued to steel. Centres popped and cut around profile.

boiler tube cut away. You can just about see the finished smoke box on the far right (and my scrap items box on the left)

tapping holes for manifold, water gauge and pressure valve - had to turn tap with adjustables, told you it was hard as hell! Slightly overdrill size would have been a much better idea! Small spirit level to check nothing moves.

dome inner boss tigged in - 4mm undercut as prep. Bit rusty with the olde tig set but nice even heat as seen by blue colouration ring

cutter teeth no more!

dome hole cut - had to chain drill it astube steel too hard for cutter!

pics uploaded to album steel boiler I cant get them to insert into thread!

Im having all the welds professionally tested by a NDT company, quote for test and written report is £60. The whole job will take less than 5 minutes. I will take pix of the weld preps also. Preps are something which requires a lot more thought than you would imagine! All welds are to be full strength, full penetration. I had to submit a full weld profile diagram with the overall designs. Welding it up with the mig would have been very easy but I think tig looks much better.

Boiler now wellunderway - photos to follow. Drawings revised as per inspecter requirements, all materials purchased, TIG set serviced. All the time consuming parts are now cut, drilled, honed. Even welded the dome bush on! Im still undecided as to whether to expand the tubes or silver solder them. Just need a 1/2 x 32tpi tap for the wet header.

I note that the drawings i have for loco's which dont have superheaters dont have cylinder oil lubrication also - and i remember reading somewhere that saturated steam is ample lubrication for a loco cylinder etc. Any known facts about this? My upcoming project (with the steel boiler under £200 attempt) doesnt have superheaters.
