Maintenance Update (painting, lapping, braking)

Wednesday 21st
John T reports:
" I'll admit it, since next time you are in the TPO you will suspect it, that I was at Toddington today. I managed to clean 6 chairs, paint 8 bottoms and cut some bolts.
I felt I owed a visit, especially as I can't attend on Saturday next."

Saturday 24th
Fred, Dixie and Gil passed through Todders, but went on to Winchcombe to play in the siphon.  Bruce painted the rail chairs that John had prepared.  We're still a bit stymied regarding doing any work on the loco while she is on stand-by.

Wednesday 28th
There are three new issues raised (probably while on the Friday Fire & Drive):
58 [MY]: Steam heat safety valve blowing @ 30 psi.
74 [MY]: Handbrake 8-9 turns; needs adjusting.
75 [MY]: LH clack passing to pep pipe live when off.  {Sorry if I misread the shorthand!}

There is a valve on the steam heating pipe at the back of the tender, which is designed to prevent excessive pressure passing into the coaching stock.  Generally, GWSR limits this to 40 psi.  Bruce decided to tackle this.  He extracted its innards and lapped-in the internal valve, and then reassembled it.  Of course, there is no way of verifying the pressure-relief point when there's no pressure, so Bruce just tightened it a shade, and we'll see what happens when we next have steam up.

Bruce was going to help Gil with the tender brakes, but I arrived and took over.  There's a "bottle screw" under the tender that has to be turned to shorten the brake linkages.  It requires the use of a BIG spanner.  It take you all your effort to lift the spanner, let alone turn it!  Nevertheless, Gil & I managed to rotate the bottle-screw one whole turn, which reduced the number of turns on the handbrake to five (to apply the brakes).

Dixie passed by, having already been at Winchcombe.  He picked up a couple of electrical sockets for the siphon; sanded ten brushes for boot scrapers; and then buzzed off again.  Bill, Geof and Ray were all working on the siphon at Winchcombe.

Gil & I sorted through a pile of technical drawings, trying to put them into some sort of order and file them in Carpo's drawers.  A few of these drawings are not on the GWSR system, so Gil has taken them to get them scanned.

Finally, I applied stain to the brushes that Dixie had sanded.

2807 is on stand-by over this weekend.  Next Wednesday and also Saturday, we have to unbox the boiler and give it a wash-out.  The Boiler Inspector comes on Monday 9th.  Wednesday will be boxing-up the boiler again, and lighting a warming fire.  Bruce wants to get the safety valve off and lap that in before the steam test … on Thursday (12th).  We may then be in use on Race Trains that Friday & Saturday.  THEN we should be free to begin winter maintenance!
