Practice Makes Perfect (Hopefully!)

Well, the last couple of weeks have thrown up a few problems.

 

The 02 is currently on the 'naughty step' pending the arrival of some replacement bits from the 2mm loco shop. Having checked the mesh of the gears earlier and not found any problems, I was fairly confident that adding the wheels would be fairly straightforward - how wrong can you be!? :angry:

 

When I tried to fit the axle gear (having checked that all the other gears ran freely), the whole drivetrain was very reluctant to move at all. I tried replacing the 21t axle gear with an 18t gear I had handy, and this meshed very loosely, so an order was dispatched to shop for a 20t gear (this being the intermediate size available). I suspect the error was in my marking out of the frames - hopefully the replacement gear will solve the problem, but if it doesn't, new sideframes may be the order of the day... Still, it's all good practice! :rolleyes:

 

Then I managed to snag a couple of rails on the layout when I dropped a pile of ironing on it! I have spent this evening replacing the rails and re-threading the chairs. I hope to solder-up two replacement crossing vees for the ones I wasn't happy with, then I need to sort out the point blades and tie bar (and figure out a way to make it all work).

At least my enthusiasm levels are good, even if I have the anti-midas touch at the moment! :D

Should you be using the baseboard for ironing ? Shame about the gears on the 02. Keep plugging away.

Hi Andy,

 

At least you are not ripping up track...only snagging it :rolleyes:

 

That final shot of the 24 and 02 looks fantastic (sure I didn't see that a midnight last night when I dropped in to the blog?)

 

Look forward to see some more....

Pete,

 

Blimey - I can't get away with much, can I?! I added the final photo about 30 mins after I had published the blog entry - the track photo didn't come out terribly well so I decided to add another photo.

 

Don,

 

Well, I have seen layouts built on ironing boards (there was a very good one at the Doncaster show this year), so why not ironing on the layout?! :D

 

The 02 is a bit frustrating, but I'm hopeful that the replacement gear will solve the problem. I must have made a mistake with the setting out of the gears - the pair of gears above these two are exactly the same type of gears and these work fine!

Andy,

 

Are you sure it's the marking out?

 

I've had problems with gear meshing on my J39. I couldn't work out why the gears seemed fine until I added the gear on the driving axle. It turned out that the stub axles for the intermediate gears weren't straight in the ###### causing everything to lock up when the final gear was engaged.

 

It's also worth checking for non-concentric axle muffs, particularly if you've used muffs without a flange.

Simon,

 

Thanks - that is something I will have to check when I disassemble the chassis. I have used the stepped gear mu ffs on all driven axles, but I will check that they are concentric anyway.

Gosh is your nawty step as big as mine as everything Ive tried recently is there :lol:

 

 

It feels like it at the moment, Nick!

 

I have just noticed that one of the coupling rods has gone AWOL now! A quick grovel on the floor hasn't located it, so I may have to make another one :angry: !
