if you realy want to freak out his teachers in a few years teach him how to read a set of plans and read grades
this way he can bring in a laser or a total station for show in tell. i usually tell people who want to run equiptment first learn to run a grease gun than ill show you how to run a excavator. but in his case he probably cant reach the upper dipper fitting so show him in a few years:usa
My son & I volunteered at the local tourist railroad. We (mom & dad) got a call one day from one of his elementary school teachers who said "we" need to discuss telling the truth with him. She said he's telling all the kids he's running a locomotive on Saturday. I had the pleasure of telling her, "he does". The engineers would let him run the locomotive in either yard switching or work train service. They told me he was the best, very patient, careful and content to wait for orders unlike some of the others. I liked having him in the cab, I knew he couldn't get hurt there
He started operating at 10. One of our friends owned his own excavating business. We saw him downtown one Saturday evening. He needed to move all his equipment off the job site and the bobcat wouldn't fit on the trailer with all the rest of his stuff. He asked my son, do you want to run this? He said YES!!!. Tom gave him a few pointers in the lot and had him turn it around twice. He then said keep to the right along the curb and dad, you follow him with your 4 ways flashiing. My son roaded it about 1.5 miles to the yard. Talk about happy as a pig in mud cool:
From then on, there was no stopping him. The MOW guys at the RR put him on a tie crane with a couple joys sticks and he was their best operator. One of the guys brought a CAT 416 to use to load a hi rail ballast truck and after an hour you would have thought he had run it for months.
You'll have lots of good memories of their younger years.
