It's a toy for a childs sand pit, made for my sons second birthday.
This item and all my other work can be found on my website http://msraynsford.blogspot.co.uk/2012/06/elis-grandparents-gave-him-sand-pit-for.html
The original was cut in 3mm laser ply and the joints were all pretty snug so held together without glue. I later went round and glued everything before letting my son loose on it
The bolts are M4 and they need a nylock nut on the inside of the wheel to stop it from coming off.
