Here we go!!
Man! That is so cool that your grandson has taken an intrest and lit a fire under this project. These times spent with you working together will create memories and skills that will last a lifetime. Although my grandfather was not that into building cars, I spent a lot of time with him in his woodwork shop. The time spent with him is precious to me. Learning about hard work, life, and building cool stuff along the way.
Awesome project. Cant wait to follow the progress.
