Thanks a lot!

Modelman, I think so! Reynald has for sure the skill and machinery to do it. He already made many big locomotives, one steamer directly from his own molding and have a long experience with steel castings. http://s1196.photobucket.com/user/B-...20de%20Reynald
His excavator and truck are also an 1:9 scale For sure it will be big stuff
But when I look at the price on the site suggested by J-hammer (thanks to you too!), around $120 each, making them could be effectively a good option. He firstly wanted to know some option to deal with, it's done!

Thanks for these rapid answers sirs! I will make a follow up of his project. But as he live far from me, I have to wait for his own pics...
