Hub diameter question re wood spokes
Last winter I won off Ebay some spoke blanks for my 21" wheels. I have turned the tenons but am at a loss on doing the hole. I am coming up with 2-3/16 on the hub where the spokes sit. I have a jig built to put the spokes in to mark for length that I could use, but 2-3/16" is not a normal hole saw size. I just need to put a curve on the end not take a whole lot off. I could go with 2-1/4" but am unsure if that would leave too much space and would have to shim. I thought about using my osculating sander but would still run into maybe same issue because of stock sanding drum sizes. Any ideas?
I know the voices aren't real but damn they have some good ideas!

I just measured a front hub … diameter is 2.185 to 2.187 … 2 3/16 " diameter … I have machined the radius at the hub end of spokes by using an adjustable boring head in a milling machine … you may be able to make a " fly cutter" type boring tool to accurately machine this surface … on my Dodge brothers 24" wheels I machined the end radius and made the spoke .020" longer than actual "correct" length … this allowed a tight press fit in final assembly … always an optimist ...Gene French

Re: Hub diameter question re wood spokes
Gene;
I thought about using my adjustable hole saw but was afraid that it might do more damage then good. I could try it on one of the spare spokes that are not usable for this project.

Re: Hub diameter question re wood spokes
Mark, the guru of wheel builders in New Zealand puts the whole rebuilt wheel in a big old lathe and bores the holes to suit. That way the hole is truly central and true to the hub.
What I really liked was that somewhere in the driveline on his set-up, a model T transmission and clutch set was used to engage/disengage the drive.

when I did the Dodge Brothers wheels I did not have a large enough mill to position the assembled wheel concentric to the spindle to bore all spokes at one time … I would do the boring in that manner now … always an optimist...gene french

Re: Hub diameter question re wood spokes
When I did my hubs I used a Dremel with a small drum sander to finish the hole.

Re: Hub diameter question re wood spokes
Thanks for suggestions. I went ahead and set my jig up on the drill press and used an adjustable hole saw. I am going to take the spokes and felloe to the shop and use the press to set the spokes and hubs on one wheel. If they go in straight I will call it good, if not back to the drawing board.

Re: Hub diameter question re wood spokes
I used a cylinder hone wrapped in sandpaper to slightly enlarge the hub bore in the spokes.

Re: Hub diameter question re wood spokes
Some models of spokes were alternately tapered and the last spoke went in like a wedge, no press was required, the hub bolts would pull it tight. All the spokes on my Canadian '26 are like that.
