Connoisseur N10 – More little details

The last couple of workbench sessions have been preparing items for fitting.

I had done the rear steps some time ago but I hadn’t curved the treads. I did the front ones and curves all the treads at the same time.

Then I dug out the buffers. I’m not sure where they came from but I had secreted a set of NER buffers in the box some years ago. They came as a Buffer stock with a separate washer to create the rims that is bolted to the buffer plank. So they need to be soldered together. I also need to drill them and fit the prominent fixings that are visible in most photos

I also made a start on making the cab window frames so that they would open. I was fortunate that I had a spare set of etches for the wind frames so I soldered two together and then soldered a short length of microbore tube to the top so that I can hinge them

Lastly I machined a replacement upper rear lamp iron from the end of an earth pin out of the 13 amp plug

There is still quite a bit of the plug pin left for making other parts with at some point.

The next job was to make up the footplate, solebar and buffer beam unit.

The idea of the design is such that if you get everything correct then the footplate just clips into place. I added the solebars and frame spacers to the lower frame at a show. A subsequent test fit of the footplate at home, showed that I had one solebar slightly out of alignment so I had to take it off and reposition it.

Whereas this snip from a photo shows a curved cut out and flat ends to the buffer beam. I have a copy really old NER photo of no2 showing the same.

This is what the kit provides.

I spent the entire day at Thirsk show just carefully folding up the fold around edges for the buffer beams

3D Designed Hand Crane – Final Fitting

At our arts and crafts group this week I added the final two stays to the 3D printed hand crane. It now needs a couple of bits of paint to touch up and the fitting of the chain/cord.

To that end while I was awaiting a visit from family today I knocked up a hook for the crane.

The images below are greatly magnified.

Connoisseur Models LNER N10 Tank Engine

I also managed to progress the N10 a little further this week.

The first job was to drill out the Westinghouse casting. I have a couple of really nice brass castings in the stash which I believe are Alan Gibson but I’m not 100% sure.
On the back of the mounting brackets there were a couple of spigots so I drilled a couple of corresponding holes in one side of a clothes peg and pressed the spigots into it giving me a secure grip when gripped in the drill press vice using another piece of clothes peg on the other side with a small parallel laid on it’s side to support them.

I drilled through the cast nuts on the right hand side then drilled a hole for the pipe that leads from the governor in the left hand side. While I ad the drill press out I also drilled the governor that I made for the last pipe and fitting.

lastly for now I assembled as much of it as I could prior ro fitting. In order to fit it to the etched mounting plate I cut and filed of the spigots on the mounting brackets and secured the casting to the bracket with 298 degree solder. Next I fitted the governor and the pipe that leads into the smokebox which is a little long at the minute and isn’t soldered in until I have it all mounted on the footplate.

MOK 8F 8425 – Smokebox Door Fitted

On Thursday before leaving for Guildex on Friday I stuck the smokebox door onto the 8F. I had planned to do it earlier in the week but realised that the handrail wasn’t parallel to the hinge straps. I removed the handrail and moved one of the holes slightly before resoldering the handrail knobs back in. I also took the opportunity to add a small turned washer to the back of the smoke box door locking handles. I had neglected this detail when I added the handles at some time in the past.

This is my rather Heath Robinson set up for holding the loco body vertically so that the epoxy didn’t allow it to slide out of position.

Those who dropped by the Technical stand on Sunday at Guildex were able to view both the 8F and the N10 in their current state, as I had them on the Sunday Display of members models.
