rejuvenating key bushings with steam

[Roger Jolly]

Hi Avery,
          I've been steaming B/R holes for a number of years with good
results,
buy your self an electric whistling kettle and remove the whistle
thingy!!!! it gives you a nice 1/8" steam jet, and is transportable, unlike
the stove. I find that glue sizing holes, tends to be a little noisier, so
I only use this approach in the worse cases.
Regards Roger
