In an effort to try to get an answer to the vacuum tank removal date question, I posted enquires on RMWeb and the LNER forum. So far I haven’t had any replies, so me next plan is to fit it. Working on the theory that it will be easier to remove later than to leave it off and then try to fit it should it be needed.
In the meantime I moved on to the front bogie (the plan is to try to get a running chassis to take along to Leigh show for a run on Saturday).
There are two options for building the bogie in the instructions, one uses L type spacers and the other incorporates side control.
I opted to go for the side control method. All went well until I got to fitting the bearings. The instructions say to leave them loose until all is square etc. and then solder them in. What it doesn’t say (but admittedly the photo further on in the instructions shows) is that the bearings need to be fitted with the flange to the inside of the frames. I didn’t notice this and having soldered them in with the flange to the outside I realised that I had a lot!!! of side play. There isn’t any mention of when/where to fit the lovely hornblock/spring castings either.
My newly bought Yeadon volume gave me a couple of reasonably clear photos of the hornblock/spring on the outside of the frames. To achieve this I had to cut away the section of the axle bush that protruded through the frames, cutting back flush with the frames. Once the hornblock/spring castings are soldered on there is just a little side play.
*Note to David if he’s looking. It would be worth adding something to the instructions at some point on which way round to fit the bearings
The photos also show quite a prominent bar/frame stretcher across the front of the bogie so I added one at each end from scrap etch.
I haven’t soldered the bars that hold the side control yet just in case I need to shorten the springs once I test it.
