Strange use for an oil thrower plate!

[linearaudio]

Amongst my on-going problems, my sons' Yamaha TZR125 needed a set of piston rings. These were duly purchased, and then found to be too tight to fit the groove- they are tapered grooves and rings, so the rings were wedging tight! All I could think to do was to find a suitable flat piece of metal, stick the piston ring (tapered side) to the plate with Loctite, and rub the ring down a tad on a surface plate. Looking for a suitable piece of metal, my eye fell on the spare oil thrower plate I got yesterday with my "timing chain tensioner mod-kit". Yes! it was the ideal size and lovely and flat apart from where some helpful soul at the factory had stamped "f" for front on one side! A bit of careful linishing to remove the offending letter, 5 seconds to bond the piston ring to the plate, 5 minutes careful thinning (with the aid of a micrometer!) and 5 minutes in boiling water while the wife wasn't in the kitchen to soften the Loctite again!
What would I have done last week, before I had the thrower plate on the bench?

As an aside, this was the first time for a while that I have used "real" Loctite, rather than the 5 tubes for £1 stuff. When I have some spare time I intend to do a few experiments to see if the cheap stuff is anywhere near as strong. Think I may already know the answer to that one, but I may be surprised!

Likewise, if that were possible! Try finding the "right shop" for 20 year old Japanese engine spares! I'll stick with moggies in future!
