Kathryn bought a tool box practice kit from Vans Aircraft. I did not know about it but she said she wanted to make it for a Christmas gift for our son-in-law to be, David. So with me to coach her she did all the work to assemble the box. She learned of the tedious job of deburring. She learned to dimple. And she learned to rivet using both the rivet gun and the pneumatic squeezer. She is a good student!!!
