One of the preserved lines near me had something similar Chris, the hole in the axlebox had worn such that it was about an inch bigger than the axle! Loco was still in service though, running monthly.
along with many problems that loco has to contend with. |

An inch of wear, that is special!! One of these has about 4 inches play in the big end bearing. Mind you, I don't think it was still running... www.youtube.com/watch?v=bsHHzCP09xs about 1 minute in. C |

Sounds like 720's centre driver at Rosewood Railway along with many problems that loco has to contend with. It was Kilrie at QPSR, before they got 448 running again. |

They are working on Kilrie's boiler at this time. 720 had 1/4"= 3/8" rock in the middle driver that I was concerned about. But these days, I am not concerned, I am having a rest . |

The Llewellyn Loco works drawing office has made a boo boo, the cylinder drain operating shaft fouls the wheel treads, just needed one millimetre. A cranked and or two piece shaft is now required. On a happier note, the cylinder drain servo fits nicely under the front plate. Its bracket will secured by the four Buffer beam screws.

Not much fun time in the Red Room, gotta make a gold coin making bikes. I was making some new fixtures for the bike frame building out of aluminium, I detest aluminium, it makes a mess, it goes every where, it sticks to every thing, coolant every where, hard to clean up. It took 3 hours to clean the piles of it from the milling and boring. And a floor wash to finish up.
 Then on a very hot and humid evening with the fan on notched up to #2 , ( I saw a fish swim past me last night) I started the process of making the lifting links.

A wee bit of time making the PB bushes for the1.60mm diameter cylinder drain shaft. I shorted the clearance problem and I think I have a KISS solution.
I drilled .50mm oil holes for kicks and giggles. I blame Rodger for this affliction :-)

More Filing buttons      The dark residue is graphite and oil, from the packing. I keep every thing oily due to the high humidity here and hot weather.  A few more bits and then it will be setting up my first ever RC servo and controller.
New stuff is fun, it is about the journey.

Some of Saturday and all off Sunday and some of Sunday evening in the Red Room. A lot of thinking and sketching time in there. 
Bushes to snug up the M2.5 Servo mounts mounted.  Another crank to make and a linkage to complete the mechanics of the drain operating kit.
I am pleased I got the thinking out of dimensions such that it all can installed and removed with knocking down the rest of the Loco.
I have never used RC equipment before and yet to rig it all up and test.

Tuesday night, after dinner, ABC Jazz on the radio, (Nick Cave is for when I clean the house, Radio National or the Cricket when working)
the crank that will connect the servo linkage to the drain crank shaft emerges from the tonnage of swarf :roll:
I started following the riksrailway.blogspot.com.au/2018/01/how-to-adjust-throws-on-deltang-rx102.html on Monday night but the thunder storms curtailed my first efforts with RC equipment but I did get the servo to move. YAY!  I went down to the Pottery Shed to show MAM.

Ground another tool up for the Cowells ME90.
Working up the cylinder drain linkage on a hot and humid evening.
I like griding up tools and I finish off with 1500 grit. I find it very satisfying.   I am using the stainless valve rods with 10BA thread that I discarded when I revised that set up.

I needed some tough spanners that can be heaved about for the bigger jobs in the workshop and take some abuse, such as a good smashing with the flogging hammer. These hitch hiked to down under by Airmail (5 weeks)

5 Weeks? Airmail? That's OzMail for you! Bits arrive here from Knupfer in little over one week.

I recently had two packages of taps and dies airmailed from London. One took six weeks and one took 5 weeks, however they both arrived here on the same day.
I think it is the effort to stop the postal drug trade. |
