Fixing a fleet of Singer Sewhandy toys

I've been wanting to get about six useable little Singer toy machines in working order for a sewing club at my school. Each machine has its own little personality. Most recently, I needed to repair a handle where the screw threads were stripped.

Springsbon from Colorado had suggested that I look at Ace Hardware, Home Depot, or Lowe's for something to help re-tap the threads. The nice young man at Ace Hardware suggested fitting it with a new screw and a plastic spacer as a substitute for the handle for now. He did end up using a tap to make new threads for a slightly larger screw. Then if that doesn't end up working, he thought that the handle could be glued in place with locktite glue.

Now I have 3 machines in working order. I'd like to find several more for a total of six!
