9MT - Underpinnings

Once the bunker was fixed in place the underside of the loco needed to be sorted. Main problem is that the main body fixing on the 9F is through the bottom of the chassis into a boss under the cab floor. A floor that is no longer there as we are using the 4MT cab.

 

After a lot of thought the following pic shows what I came up with

A section of 4MT floor under the cab area with the 9F boss turned down in height and bonded on, with extra sections from the other 4MT grafted on to take account of the bunker and tank extensions. The front section left solid and screwed to the 9F boiler lower. As the chassis now screws to both the boiler lower and the cab floor it all ends up being a solid unit. I'll use the under bunker screw fixings and the original 9F front slot arrangement to secure the body on.

 

The boiler lower needed to be filed down a bit as you can just see so that the section of 4MT floor fitted properly. Much cleaning up and a lick of paint needed, but that's one more engineering problem off the list. A representation of the rear frames above the rear bogie are needed too. Will probably be in plasticard bonded to the floor.

 

Time for an assembly and track test before moving on to the details and finish.

 

Do I butcher what's left of the 9F cab to get the backhead or just keep the smaller 4MT one, hmmmmmmmm

Maybe take a photo from "normal viewing angle" (whatever that is) and see if you notice the wrong backhead?

Thing is, I will know it's wrong. I've had to cut down the 4mt backhead as it does not slope rearwards and fouls the 9F motor mounts. Pretty sure the razor saw will be out soon ....
