Trolley Top questions

Several people have done them by now.
How difficult are they?
I am familiar with Doug Hodder's Teardrops, he has done 2 and I have also seen one made by another man, the copper top, from the UK.
I went into Doug's album and pulled these up hope you don't mind Doug!!
I had wondered what type of wood is used for the gutter and the top.
the Gutter looks lie steamed wood rather then plywood. and would you use the same type of wood as you use on the front of a teardrop to make the bend?
I am still not sure if I will attempt to do this on top of the Cross Bow in builders journal ( viewtopic.php?f=50&t=54108 )
But Trolley tops have intrigued me for years.
I am sure there are others who have wondered how it is done and have come up the their own way of doing it.
Doug is now making he second Standy (dictionary wants to spell it standee I like the Y better time to event new words) and enjoys the world of invention. He is a very creative man. And cooks great waffles.
