Another MOK 8F !

Hi Dave,

My kit has the smokebox door, one thing I did check after seeing that some kits came with cast brass ones rather than whitemetal

It used to be whitemetal in the old days.
I believe Dave told me he could buy them in a lot lower quantities in brass as he now only stocks the bits in smaller quantities if at all.
He must have found someone to do the fireboxes in smaller quantities to as he used to have to buy large amounts of them to.

As this build is for a Horwich built engine, I've had to modify the cab side sheets:


Have removed the vertical row of rivets down the centre of each cab sheet.

Hi Ian,
Can you save the spare rivets for me

John,
I'll have to glue them back together first !

I've moved on to looking at modifications to the firebox and boiler.

Firstly the firebox, which does have differences compared to the casting from 20 years ago ! However, I decided that the cast mounting plate for the safety valves needed to go, to be replaced with brass sheet of the correct shape:


You can see the differences here, with the brass replacement being fashioned on that from a view above 48305's boiler/firebox in the Wild Swan book on the 8F's.


The replacement part in position awaiting soldering, after which I'll drill into the firebox and fit some 0.5mm rivets.

Whilst at the East Anglian Model Railway Show I purchased this little lot. Thanks JohnK !

Although progress has been slow, work and that damned turntable, at last the safety valves are now in place atop the new mounting plate:



The current job is filing away the cast firebox wrapper bands as these will be replaced with etched items, slightly modified.

After filing, measuring and drilling.....





Plus a little lathe work.....



It's getting there, slowly !

Having ordered some nickel silver strip from Metalsmith (LankyTank) so as to make the coupling rods a more prototype width, and shape, I carried out some work on one of the connecting rods today.

As can be seen, the three etches in the kit produce a rod that is overall too narrow. The prototype is 5 inches wide and 6 inches wide across the boss.


Some 1 x 1.5mm brass strip was used to deepen the fluting as it is too shallow. As I had two sets of connecting rod etches, I have used the bosses off two pieces to widen the boss width.


At the crosshead end I'll build the boss up once I know how the connecting rod lines up.
