A question about your Wyvern.

Hi I have recently stated a Wyvern . Not sure how to machine the cylinder though there is a lot of metal to remove and the finished item looks fragile .
I have made two engines from Cotswold Heritage , very nice kits .
I also have an untouched McOnie kit . The base plate is too long to machine on my little mill but I will start it soon .
True the earlier kits have a nice forged crank ( not cast ) and my copy of the Book Building a Verticle Steam Engine from Castings covers this item . I made a simple jig as detailed in the book to machine mine .
