    Old tubes have been very carefully cut out with a tungsten carbide cutter as there is no room for a grinder.
    ( It takes about an hour to cut away just one end of a tube)
    Tube replacement and barrel replacement is been done in Two stages so dimensions can be kept under control.
    The boiler is currently with the pressure vessel welder.
    17 x 500mm long tubes
    9 mtrs of tube needs to be purchased of 4mm or better wall thickness.

    One picture shows wiles senior and wiles junior safety valves side by side.
    They are different sizes, but the boilers are the same size ???????
    The safety valves are to be sent away for testing and inspection to keep the boiler inspector happy.
    A new glass is currently being made for the pressure gauge.
    I Found a siphon for the gauge, but it is a bit wasted, so I am trying to find some suitable pipe to make a new one.( the original pipe used is not a drawn tube, but has a seam running down the side which is surprising to find on a boiler)
    In another photo I found in my stuff is a large brass operation plate which is only fitted to earlier Wiles senior cookers and all the stationary units.
    As built they didn't fit the plate to the juniors.
    There is nothing special about the steel in the boiler or tubes.....it is just mild steel.
    The housing the tubes are welded to is flat plate which has been pressed into shape and the side of the box welded up....all very simple using non strategic materials for a WW2 design.

    I have looked at the oven.
    The old rusted floor has been cut out.
    As usual the rust is worse than I thought.
    One side of the oven where it fits up against the boiler will have to be replaced and that was expected.
    What was not expected is the need to replace various angle iron supports and various sheet metal internal baffles......all a lot of work.
    The main aim currently is getting the boiler to steam as the oven can be bolted on later when repaired.
    I am still trying to get my head around how the hot air from the oven fire flows around the oven and how the oven fire draws fresh air.

    The address on the brass plate brings back memories Ron.


    The Refrigeration Co I worked for at Marleston used Wiles Manufacturing's Hot Galv Baths for our Galvanising needs. Mainly steel wire shelves from the Domestic Fridges we made.

    Like most of that type of factory, the Roof & Walls were eaten out due to the acidic atmosphere & you could see from one side to the other. When it rained..... Don't ask. Still it was Post War (circa 1950) & materials were still hard to come by.

    So, good progress on the Junior then?

    New tubes are in.( Eight hours TIG welding work.....that's going to hurt the hip pocket.)

    The second stage is to fit the new boiler barrel.
    New glass fitted to pressure gauge done and had a spare glass cut ,just in case for the future.
