If somebody came on here saying that they had a machine that was running rough, ie .....
Sometimes not completing its cycle
Wouldn't we ask them if it'd always behaved like that and then tell them of the evils of dried grease?
I for one have being trotting out that one for years now, along with how to degrease it and to use light oil except where coins come into contact.
So guess what I did when I decided to tackle a Clement & Whales Greyhound Stadium that was spinning slowly and not always getting to the end of the cycle especially on the higher pay outs? Naturally I gazed knowingly at the triple ply layer of hard grease that coated 80% of the moving parts and advised myself to lay the whole mech on its back in a basin and pour in diesel & paraffin until everything but the dial was covered.
Two days later I removed a sparkling mechanism from a swamp that could have easily supported a spoon upright.
Happy days? ...... errr, no not really.
It transpires that it was only the grease that was holding everything more or less in line as well as taking up the slack in the wear between parts that needed to be exactly so far apart.
Who would have thought that the groove carved in the solidified grease by the pin holding two links together was the only thing allowing the last part of the cycle to: -
Release the handle to return
Fire the pay out fingers
Dictate how many slides released ???????????
What were the chances of a previously working Clock to suddenly have such loose bearings that not a single axle was running true leaving the teeth on the cogs trying to run high point to high point. They were so skew whiff two were hardly perpendicular now the grease was removed.
So far six interactions between levers that need to shove each other at the right time are anything up to 1/4 inch adrift, forget thou!
Outcome? I'm now learning new skills like ....
Clock making ... gear cog .... lathe
Re forming bearings with solder
Building up worn gaps between partner levers that need to interface closely.
So what's the answer? ..... I haven't a clue, what I do know is I've been guilty of mending something until it's really broken.
BP ..... Now starting to understand the difference between 35 years experience as a slot restorer and one year's experience 35 times ..... Gulp!
