Penny Farthing Bicycle
Powder Keg:
I got quite a bit done on one of the hubs last night. Was too late to post pictures though. I'll do it when I get home\o/
I like hearing these stories. I haven't seen one of these bikes around here for 20 years.
Powder Keg:
Made progress on the second hub\o/ I have to make a jig to hold them in the mill to drill the spoke holes. I will need to broach a 1/4" key way in both of them to.
The jig will also let me file the large radius smooth and finish the outside. There will be a couple of angles turned so the spokes enter at a 90 degree to the outside of the hub.

Hi Ned..... is there a difference? As hes British I suspect not.... and afore ya go off at me.. we're still part of the Empire out here in Aus....
Powder Keg:
I broached the hubs today. I'm going to change the profile a little from what I had planned. The rim will be a little thinner and the skinny area will be tapered some. Man! Its been hot the last day or two. Hard to go out to the shop....
villiers:
I know a bloke who both makes and races these beasties. In fact he has several of them for different purposes, sprints, races, touring ,etc. I know him through our mutual interest in vintage motorcycles so have only half listened to him when he chats on about sweatwheels. I do remember him remarking that the steering head angle is critical and that despite experimentation he's found that the angle used by the original makers was by far the best and that the best results were found by following the original specifications. He was very positive that the original makers were right on the ball in how they made them. I'm sure he also mentioned they used a plain bearing in the head stem not balls as used in the common bicycle of today as a certain amount of friction there was very necessary.
Sorry I can't be more helpful but I only see him every few months so won't be able to follow up for some time.
Cheers, Villiers Bob
