A lovely thought by your children, and a very useful device. If you are like me, you may well use it quite a bit.
Without wishing to spoil the fun, do check the accuracy of the division chart supplied, if you are going to use dividing plates with it. Sadly, I found out the hard way (trying to cut a 13T gear) that there some errors and omissions in the chart supplied with my Vertex HV6.
Neil posted my revised chart on here somewhere, if you want to search for it.
