Delph - Cosmetic chairs on first point


Dave Holt

462 views

After what feels like a lifetime of back-aching effort, leaning over the board to focus my magnifying head set thingey, I have now completed fitting the cosmetic chairs to the point on the current board. Not only did thids involve cutting each chair in half to fit round the rivet, but also reguired lots of grinding of the rivet heads either side of the rails to enable a snug fit for the chair halves. On some, I didn't quite achive this, but the overall result is quite satisfying. I did consider only fitting chairs to the visible side of the rails, which would have halved the effort, but in the end I decided to fit both sides - must have too much time on my hands!!

 

I've also experienced some problem getting the point blades to throw over fully, especially on the diverging road. This was causing derailment of the loco front pony truck when travelling in the facing direction. This seems to have been solved by increasng the Tortoise throw to near maximum and an adjustment to the operating link to the TOU.

Photos show the completed point with BR Standard Cl2 tank being used to test the throw of the point. Also a close-up of the loco in its part completed condition.

Next to do on the track on this board is represent the rail joints by cutting through the rail head at the appropriate locations to represent 30 foot and 60 foot rail lengths. Intending to use a slitting disc on a flexible shaft drive for this. Then it's cosmetic fish plates.

 

Cheers for now,

Hi Dave,

 

The track laying is looking good... I have to add cosmetic chairs - is it easier to grind the rivets or file out a groove in the back of the halved chairs with a round needle file? I have used the latter method before but admit I had not considered the former.

 

What size slitting disc do you intend using for the rail joints?

 

Cheers,

 

Robin

This is going to be one superb layout Dave, as it's looking so good now. I understand the small niggling difficulties of things like point blades not throwing over properly, but fitting individual half chairs on every sleeper is something else, and only for the absolutely dedicated. biggrin.gif In an endevour to eliminate Bachmann couplings, I've been messing about on some reverse curve 32" rad track on the workbench, and that's bad enough.wink.gif

Robin,

 

The slitting disc is 0.6 mm thick - rather wider than a scale rail gap, I think, but much easier to use than a razor saw. I tried a saw but found problems with the teeth spacing being too big, even though the saw was the finest I could find; and I found it hard to make a clean single cut and not to mark the adjacent rail head. Actually, I cut the dummy gaps this morning, so I'll have to obtain the fishplates now - etched brass mainly, with Exactoscale plastic at the crossing where it needs electrical isolation.

I haven't tried filing out a groove under the chairs, which might be easier. I did try opening up the moulded hole with a hand held drill bit, but this just resulted in destruction of the chair. I'm using Exactoscale and they are very fine but the moulded hole does not seem large enough diameter or deep enough to fit over a brass rivet head. I notice the moulded location pips on their plastic sleepers are quite shallow, so I suppose the chairs are made to suit. Perhaps C & L might have been easier, although they don't do such a wide range.

Standard 2 looks like DJH.

 

Larry,

 

Quite right. The BR standard tank is based on a DJH kit. Unfortunately, the kit results in the loco being 2 mm too short (all in the cab/bunker section), so I have stretched it by widening the cab door opening to give the correct length. This is not strictly accurate but is better than nothing. The chassis is Comet with added details. The pony trucks are Brassmasters with the rear one modified to represent the swing-link side control. The injector pipe work was fun!

 

Thanks also for the kind comments on the layout. Just hope I can live up to expectations!

 

Cheers,

 

Dave.
