Mike,
Welcome!
Pre – recent retirement and following an engineering career, I provided apprentice training and assessment for a few years in the engineering workshops of local ( Bucks) industry, any and all exposure to 'making things' in school is to be applauded in preparation for considering these career options.
I am well aware how hard it is to produce 'interesting student projects' particularly for groups of learners and as an example the most popular with learners was the -desk holder for the mobile phone. The holder could be in a variety of materials and production methods. (Not actually a V block but required similar skills.)
Like others I would be interested in the mill and pay a fair price, collection is no problem.
Best Regards
Pete
