Eddie Gibbons has previously displayed his K3 and H4 chassis at Harrogate on the club stand.
Below is the start of construction of the two chassis in pictures.

Eddie’s Gresley Moguls – The continuing story of the GNR H4 and LNER K3
After the first year’s work on loco frames, I decided to start on the tenders. There’s nothing worse than getting a loco complete and ready to run, and then having to start on the tender – bitter experience!
Left The two loco frames were exhibited in May 2006 at Harrogate.
Right Work to overhaul one of my other locos delayed work on the new engines and in June the plates for the H4’s GNR Class B 3500 gallon tender, annealed, straightening and descaled, are seen, marked out, on the milling machine for being drilled
Shows the same plates from a different angle to show the many rivet holes Here the frames are seen after drilling and profiling.
Left The K3’s tender is the LNER Standard 4200 type and this illustrates the marking out of the plates prior to machining.
Right A few parts had been made earlier in the year and here are some frame stretchers for the GNR tender. The structural Ts are machined from the solid.
Left The frames for both tenders almost ready for assembly, now with fabricated horns, spring hanger brackets and top angles riveted in place.
Note the inner frames of the LNER tender and the fabricated frame stretchers and brake hanger supports .
The riveted rear drag box for the GHR tender is partly made.
Right A close up of the riveted drag box
A view of the LNER tender stretchers The front drag box of the GNR tender test assembled
The drag box stripped down for cleaning prior to final assembly and silver soldering
The two tender frames erected. The 4200 gallon tender frame close up
And a view from above The 3500 gallon tender frame.
Note the simple design compared with the later type
And a view highlighting the riveted dragbox, a difficult assembly. The loco and tender frames exhibited at Harrogate in 2007.
Note the progress on one of Jimmy’s two 9Fs in just a year.
The LNER tender with axleboxes And now with axles
Two dozen spring hangers part machined Part machined hangers on the drawing
Spring hangers almost complete Machining the backs of the hangers
All nearly finished A Spencer spring block top being machined
Spring blocks in various stages of manufacture Sets of six blocks in various stages of final hand finishing
Spring plates halfway through bending The plate roller made for the job
Plates bent, drilled and ends chamfered ready for assembly A top plate in the jig for soldering the retaining bars in place
The GNR frames with springs in place The LNER frames ditto and ready for the tank. April 2008
