@Malcolm - Most of us in Fife do have double decker cars, that's why we need the car stairs

(sorry best I could do with that one

)
Well, I finally got a day off from kitchen building work at the weekend and did the changer flush. Actually I flushed out all the mechanical movement points, i.e. the bushes, the rod connectors on the cross shafts etc etc. Then I used the teflon grease to relubricate the whole guitar.
I took pics as I went and I'll open up a new topic once I get a chance to do some editing etc.
I also used strips of 1200 grit paper with chrome polish to smooth off the changer fingers, take off any burrs etc.
Following that I cleaned and polished the guitar and put on a new set of Live Stainless Steel strings, finally got it tuned up about 10pm last night. It took me 8 hours on Sunday to do the flush and lubricate, 3 hours Monday night for the clean and polish and 3 hours last night to put new strings on and get it into basic tune.
Before I started I remembered back to the days when you used to de-coke a car engine, I did this a few times and a mechanic friend of mine advised me to leave a small ring of coke, (charcoal guys!), around the circumference of the piston where it met the cylinder, otherwise it could lead to piston slap due to normal wear and tear. I had visions of flushing out the changer and discovering that the muck & grease were holding some of it together
I'm happy to report that nothing of the sort happened, I did have to shift my RKR a bit as the screws holding it in had come loose and it was sitting at an angle. When I removed it I discovered that this had been done before, so I picked a spot between the 2 existing positions and fixed it in there, re-adjusted the rodding to suit.
I have to say that this has made a huge difference to the action on the guitar and the tone I am now getting. OK it is new strings, but I remember when I put new strings on last year it didn't sound this good, and there were a few buzzes which are no longer there. I was giving it a go and my wife came into the room and said - "That sounds amazing, much better than before", as she said, if she noticed it must be good. It's difficult to describe but the tone just sounds much more even and mellow over the whole guitar. The strings I used last change were Live Strings Nickel and these are Stainless, so it's hard to do a direct comparison but I don't think it is just down to the type of strings.
So I'm really pleased that I took the time to do this, I can't wait to get home tonight and fire it up. It was a lot of work but I guess that I won't have to do this again for quite a few years, just a re-lube every year perhaps?
Something I noticed when I was tightening up the machine head screws was that if you tighten them right up it locks the machine head, does anyone know if this is function of these machine heads,i.e. can the screws be used to lock the machine head without damaging them?
