Vintage Windmill and Wind Generator Forum

I've been out of touch for a while. Looks like you got more info than you thought. Good job guys.

Well I just ordered a roper whitney off ebay. Though not sure what size die is in it. Guess I'll find out when it gets here. I'm assuming 3/8 is the usual size for the towers or 1/2?

3/8 is common here. Woodmanse towers can have a bit larger.

3/8 is the most common here as well. For bigger mills, the bolt holes are proportionally bigger. You can take a 3/8 punch hole and drill it out bigger as needed.

thanks Thomas for getting a hole punch , so close to me I now know where to borrow one .

Ah okay, well hopefully the die in it is a 3/8. Hahaha and no problem Mike, anytime
