RARE DOLL 378/1 BACK TO STEAM... ADDED ENDURANCE TEST VIDEO
By: therat05 Date: September 17, 2019, 4:09 pm
---------------------------------------------------------
Recently i had the good fortune to be given this rather sad and
rare 110 year old Doll 378/1 engine covered in its thick Black
paint overcoat , who can do this to an engine.
I had a picture of a Doll of the same type and could see the
attractive colour it should be.
So began the long job of refurbishment, the whole boiler looked
as if it had been in a cricket match... as the ball, the end
caps both leaked water and steam so had to be removed, the water
filler bush and the steam pipe bush and pipe all were loose and
leaking so removed....next was the boiler which has to be
unsoldered from the fire box as it is attached by lugs.
The boiler was patched and repaired the bushes resoldered the
end caps cleaned and re soldered back onto the boiler, then the
boiler resoldered back onto the firebox taking care not to melt
the endcaps solder....this was followed by many hours of solder
removal and polishing.
The base had so much Black paint on it that it took 3 coats of
paint remover to get it off back to bare metal, it was then
degreased and 2 coats of Hycote spray primer applied followed by
3 coats of Hycote Red gloss , this model had a lined edge to the
base this was in Bright Yellow gloss .... i did this free hand
using Humbrol enamel paint.
The last job was to solder the very thin steam pipe back on... a
tricky job but luckily i have done many steam pipe soldering
jobs so it was completed first time, after a test on air the
engine was steamed .....
Here is the video of it in steam followed by some pictures of
the journey....Steve

ENDURANCE TEST
IF YOU CANT SLEEP THIS IS THE VIDEO FOR YOU 😂
I REDUCED THE AMOUNT OF WATER IN THE BOILER AND THIS SOLVED THE
PROBLEM OF CUTTING OUT AFTER 30 SECONDS ON START UP.... HERE IS
8 MINUTES OF PERFECT CONTINUOUS RUNNING FROM THIS 110 YEAR OLD
DOLL 378/1

Thank you Bruce a happy ending for the engine the outcome was in
doubt until it was completed mainly through boiler
concerns...Steve

I have been thinking about the fast short run and water from the
piston at the beginning of the run may have been due to over
filling the water in the boiler leaving not enough room for
steam, it ran perfect in the 2nd half of the video when the
water level decreased....the engine has had more perfect runs
since the video with less water so my fault to much water ::)
...thats my theory anyway...Steve
