I need direction as to the perfect engine to fill this requirement.... In two days , Myself and another tech teacher are going to try to start a club at the secondary school where we teach. I have total access to the machine shop. 9 lathes 4 v mills 1 horiz mill. Adequate tooling, and what isn't covered by budget I can purloin, I'll pay for. We have several reasons for this club... We're interested, We want the kids interested in the hobby and the trade, and We want to foster interest in the machine shop as many of these are being gutted by the school boards (you can do it all on line instead...) So we have the option to build engines ( the first sets anyway ) on an assembly line basis. For the rest of this school year the shop isn't scheduled for anything that will interfere with the setups. We're planning a half hour a few days a week before school. if we can get (and keep) the kids interested. We'll sneak in the shop skills like measurement, filing, set-up, and layout as we go along, And after a few set projects we will let the advanced ones select their own projects. Can the collective wisdom reccommend a design which we can use for this project? Many Thanks.
