So I actually made it into the workshop this morning and it turned to be quite productive in as much as I refitted the desk console/floor unit in number 1 end, having first re-fixed the lighthouse LEDs and followed this up with fixing the cabs to the main body

 

which turned out not too bad (no worse than the first build), a bit of judicious filling should sort things out.

I then concentrated on the bringing down brightness of the LEDs, I had already put resistors onto the + blue leads but thought that they were still too bright, so I introduced 5k resistor to each line immediately before the wires went into the terminal block on the decoder.

I still think that they may be too bright, but the bigger concern in the overspill on the white lights, again, this may reduce if I put larger resistors in but I think that I may have to insert a sliver of blue-tac or the like to contain the light behind the disc without giving the appearance that the disc is 'solid'.

The next task is to get the filler in and get some weight into the body in the form of self adhesive wheel balance weights and then think about painting.

looks good, but a warm white LED is a better representation of in incandescent lamp

Hi 47606odin,

 

thanks for the tip, I shall have to bear that in mind for next time as there is no access to the LEDs now that the console bulkhead is glued in. I might try a dab of paint on the ends to quieten things down.

A productive morning in as much as I was able to bur down and clean up the filler that I applied the other day and also sort out the 'overspill' lighting problem associated with the white running lights.

My initial thoughts were to insert a plasticard wedge but that was soon discarded as I remembered that I had some 2mm id plastic tube and realised that as there was at least 1mm of the lighthouse protruding out of the front and that there was no way that I could get into the back to change the lighthouse if it failed, I hit on the idea to put the tube over the end and superglue it in place, having first cut it just overlong to be a snug fit behind the disc itself.

The single top light was tackled first and things were going too well as I soon discovered that when the disc was placed over the tube, some of the outside of the tube was showing beyond the disc. First try at remediation was to file down the opposite side of the tube but not having a very thick wall to begin with, the amount removed was insufficient to solve the problem, The lost wax casting of the disc has quite a large piece on the back for fixing purposes so I rigged up the drill with a slitting disc on the end of the flexible shaft and holding the disc firmly in a trusty pair of pliers I ran the slitting disc along the fixing pad effectively reducing the width by half and this together with the trimming of the tube brought the edge of the tube well inside the disc rim. I tidied up all surfaces applied superglue to the model and maneuvered the disc in place ensuring the the hole in the disc was directly over the end of the LED and that the representation of the hinge was vertical. Waited a few minutes for the glue to set and connected the body up to the chassis, applied power and was very satisfied with the result, The 'B' end was then tackled in the same way.

 

'A' end

'B' end

the body is only resting on the chassis hence the list. What looks like 'light overspill' is in fact where I filed the old superglue residue off and had to go down to the bare body to clean it off completely. The body will be re-primed immediately prior to painting.

Nearly there, just the makers plates to apply

 

 

 

 

and then another visit to the paintshop for the weathering, which will hopefully overcome the marks etc that have been picked up during masking operations - of which there were many!!

Warning flashes and logo now added as well.

I must say, that certainly looks as I remember them,(dirtier of course),and in later days, faded blue and yellow.

The camera always shows up the errors......................



somehow, the D has gone 'awol' between my den and the workshop, so that will be rectified when I return from the Club later this afternoon.

 

 

 

 

all in all, I am quite pleased with the outcome so I will keep the tools on the workbench, especially as I am waiting for the postie to deliver a small package from Skipton expected later today - more of this soon.

Now that's more like it...................

Well, another twist in the Class 22 saga, this time slightly more concerning than loosing a D prefix.

I took both 22s to the Club yesterday afternoon to give them both an outing, the blue one ran faultlessly and the green one siezed up!! I gave the green one twenty minutes on speed step 35 A cab leading then turned it round to Bcab leading and before I powered up, took these

 

 

 

 

and then again set the throttle at speed step 35 and after ten minutes the green one stopped dead and on inspection the powered bogie was siezed up. End of running session for D6320 and into its box. When I reached home, I stripped the bogie down, (thank heaven for the bolted together bogie chassis) and the first gear from the drive shaft worm had had most of the thickness of the tooth worn away. Needless to say that the errant motor is on its way back from whence it came. I now have re-assembled the bogie, minus motor and re-connected the pick up wires to the decoder so that I can at least have the sound on while it is coupled up as a 'calf' to D6326 and we shall see what occurs this evening at the Club. Thoughts are now straying to think what the MX699ks can be re-used to power?

New readers start here....................................................

And that photo, Gentlemen, is why I sold my Steve Beattie kit build version; I just did not get the look of the noses right at all....

Angle of the windscreens was wrong, which threw out the join to the nose, which also had something indefinably wrong about it - possibly not high enough?

I got stung with the failed LLCo proposed model, and had been hoping Dapol would do it in O, since their OO & N versions are well regarded - but after reading about running issues with the Dapol Bubblecars, I'm now thinking that might not be an ideal solution either!!

Maybe I should save really hard, and commission a certain  someone  to build one for me??!!
