Today, I spent a few hours with my grandson (aged 6 years and 8 months) building a tool box for him to store his ever growing collection of woodworking tools. Most of the work was done by him.
In particular, he did the sanding of the two sides and the bottom of the box almost completely unassisted. Here is a picture:
The wood is 19mm fir plywood and a each of the three pieces measured 20 cm by 60 cm. The sander was a Festool LS 130 EQ Linear Sander. The wood was sanded with 80, 120, 150, and 220 grits. He made all the paper changes by himself and lined up the paper over the holes. He was also able to turn on and off the sander and to utilize the botton that allows the operator to take his finger off the trigger. Even the hose did not seem to get in his way. He has asama, so the dust collection is very important.
I think that this demonstrates the ease of use, the effectiveness, and gentleness of this often overlooked sander. I would not be without it.
