I've made the repair you described to my Shive machine a number of
times. Use a plumbers acetylene or oxy-acetylene torch and plumbers silver
solder. Jerry

Do a little more of that work which you have confessed to be good,
Which you feel that society and your most Just Judge rightly demand of you.
Cultivate the tree which you have found to bear fruit in your soil.
If you have any experiments you would like to try, try them.
Now's your chance.
Henry David Thoreau, Journal entry, 1850.
