That sounds good Bob. It will be a week or two yet till it reaches into the 70's here but getting close. With no cool breeze today is perfect. Nearly finished repainting the wood structures. I might replace the roof on the goods shed with a plastic one, once it needs painting again.... it is down to about 2 ply now.
Time to keep an eye out for snakes again. At least we don't have bears to worry about :>)

Always one to retest theories I decided to do a complete clean of all wheel treads and the track as part of a spring revamp. This started off just with cleaning and oiling pickups and bearings on the engines as a matter of routine maintenance, however I thought it would be interesting to once again see how reliable the locos would be with surgically clean track and wheel treads.

Result, by day two the railmotor was already jerking and or running away on its own devices and the 48 class refused to start without a push at one stage. Back to powdered graphite and all is well in the world again. Sometimes the scientific process to be skeptical of all results can mean unnecessary extra work but it is good to know that the previous testing in O gauge stands up with the long history of success in smaller scales. :>)

That'll teach ya!!! ;)

I kinda did the same thing this weekend.  I replaced an 072 lefthand turnout with an 072 Wye not long ago.  All engines seemed to run fine in and out of each direction.

I placed my Williams USRA 4-6-2 on the track and let it go round, but when I brought it back into the small yard it derailed going thru the left turn portion of the Wye.  I must have tried it a dozen times, noticed the 2 front wheels of the pilot truck lifting off the rail every time (When did this start :shocked:).

I fooled around with the pilot truck, finally getting it so it derailed no matter which way the engine went :bang:

I ended up putting a piece of "spring" under the pilot truck mount and that seemed to fix most of the issue, but if I slowed down enough it would derail (going at 1/2 throttle it went right thru, go figure).

Then it hit me...check the rail dummy!  The piece of rail just beyond the frog was raised just a hair, I got it back down and glued/spiked and so far it's worked :2t:

I could probably take the "spring" out, but I'm going to wait a while and see what happens.

Yes, you would think I would learn by now Bob :>)

Leading and trailing trucks are often a source of some concern, good to hear you have solved this one Bob.

Sun is out, wind is low, might get some more train running today.

This photo represents a good deal of filing and drilling of the bearing block ,chassis and boiler to get the motor and gearbox to fit. Part of the penalty for using a 3-rail designed item i.e. not designed for regular motor /gearbox.



The pack of guitar ferrules are used with nails as coach roof ventilators.

Good start Bob :thumb:  Looks to be fairly heavy already, was the chassis already machined for the axles?  Are the drivers machined/drilled for the side rods, etc?

Keep those photos coming :rah:

Hi Bob, even with the boiler and chassis in aluminium it will still hurt if I drop it on my foot.

The  bearing block had the holes drilled to locate the axles. It is made of brass and can be unscrewed to drop the wheels out if needed. It is a Col Shepherd item that is often to be found under Australian 3-rail locos.
I think the rest of the loco will disintegrate before these wear out :>;)
Here is a photo from the bottom.




The wheels I used are Slaters from the UK. They are pre-drilled for attaching the side rods and come with crankpins.

regards
 Bob

Here is a dry assembly of the major parts of the 59 class mikado 'kit'.

Lots of swear box entries to get to this point :>;)
