An heirloom for the youngest grandson

I used 5 inch wheels  as I wanted the wagon to sit a little higher. http://www.harborfreight.com/5-in-polyurethane-heavy-duty-swivel-caster-69852.html and http://www.harborfreight.com/5-in-polyurethane-heavy-duty-rigid-caster-61757.html    We bought these metal pieces for the straps http://www.lowes.com/pd_44138-37672-11662    Our Lowes didn't have snow blower parts in July. But we were able to find a shear pin  in the draawers where much of their specialty hardware connectors are located.  . I opted to screw everything together and not use nails.  Thanks so much for plans that include a seperate shopping list and cutting list and easy to follow directions.  The wagon was a huge hit with the birthday boy.
