upright flanges with threads

[John Ross]

Hi Mickey,
Replace them all.
To get a quantity the same size, just wrap the cord, around a piece of dowel
and cut with a razorblade. Make a jig on a piece of wood, that accepts the
screw hole, and put a nail in that gives you the exact size loop as an
unbroken one. The cord is available from Schaff or any of the suppliers. A
nylon fishing line would work also. Use CA glue, it sets up fast.
Regards,
John M. Ross
