Doing the second side of the hubs. The chuck jaws are really close to the tool post. But they cleared\o/

A Gismo ??? If it has a flywheel or spins and is made with small parts. I'll take one! If it makes noise, moves, or requires frequent oiling and dusting it's a better deal yet. It's especially right if its shiny and bright; but if it's dirty and dull it wont mater at all...

I tapered the skinny section of the hubs a little and remover 1/16" from the inside of the flange. I also removed another 1/16" from the recessed portion of the hub. I'll profile the outside of the flange after my arbor is done.

I lost my head building my arbor this morning. I threaded it for 1" - 12 TPI. But the nut I had was 1" - 14 TPI. If you thin the nut up alot it will go on :dremel: It will be fine for what it's doing.

I have the outside profile done. I can start drilling and tapping the spoke holes. As soon as I get a tap.

I managed to get a lot done today. I worked on the back wheel hub. It started out as a long bar of 660 bronze.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing029.jpgPenny Farthing Bicycle

Chuck it in the lathe, Center it up, face it off, clean up the Outside, mark a line or two, start whittling.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing030.jpgPenny Farthing Bicycle

Mark more lines, Whittle some more.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing031.jpgPenny Farthing Bicycle

Rough out the rings with a lathe tool.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing032.jpgPenny Farthing Bicycle

File the radius to shape.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing033.jpgPenny Farthing Bicycle

File some more.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing034.jpgPenny Farthing Bicycle

Drill the hole so the axle will fit through. Then bore for bearing.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing035.jpgPenny Farthing Bicycle

Turn part around in lathe, Indicate in, Whittle a bit on other end.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing036.jpgPenny Farthing Bicycle

Bore other end for bearings. Almost done now\o/

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing037.jpgPenny Farthing Bicycle

I now have to make another arbor to hold the hub while I finish the flanges on it and drill the spoke holes. I'll try for the right thread this time. LOL

I'm getting pretty excited now. I can almost feel the wind in my hair\o/

I would like to roll the threads. But a threader is about $150. (the ones I could find) I'll have to cut these with a die. The spokes are a little bigger than standard size. So I hope I'll be OK. Standard is about .090" and mine are .125". Some were whats called "double butted" About a half inch on each end was bigger than the rest of the spoke. I have no idea how they would have done that?

Hi Wes

The double butted is a weight saving idea ,, they draw out the centre of the spoke to to make it thinner ,,,,,,,, Yep thread rollers are not cheap ,,,, after one myself .. Using a die for the threads will be sound on a penny farthing ,, cant see you doing any bunny hops or stunts on it  :lol:

They do all kinds of stunts. Ride downhill with your feet over the bars, You can hit the brake hard that way and land on your feet. Just don't be going fast when you do that one :bugeye: They stand on the peg and petal the left side with your right foot. Many others. But your right. No bunny hop's or Wheelie's.

A fellow gave me the plans for authentic pedals off of a 1880 Penny Farthing bicycle. I started cutting out the barstock for them today. There are quite a few little pieces. But I think they will go fairly fast. They are all pretty straight forward parts.

Got some done today. I made an arbor to hold the back hub while I drill it in my dividing head on my mill.

I also started on my Pedals. I managed to get the Axles machined. I'm pretty happy with how they turned out. They took about twice as long as I thought they would though.

http://img.photobucket.com/albums/v652/Powderkeg3418/Penny%20Farthing/Pennyfarthing042.jpgPenny Farthing Bicycle

Next I'll get back on the back hub and get it finished. My spoke material will be here next week\o/

Ahh, so that's how a "spoon" brake works! Not sure I'd want to rely on it...

Wes - your machining skills are just awesome. I'm loving those axles with the feature in the middle, I would love to be able to turn something like that.

Just out of interest, how long does it take to go from the square-edged (machine-cut) "blank" to the fully filed version, and how long to go from that to the fully polished & machine-mark free version?

Thanks AdeV :wave: Anyone can what I do. I draw up what I want to see how it will look. I can make changes there pretty easy. I dimension the steps and the diameters. When I start I'll clean up the OD of the part and use Hermaphrodite calipers to scribe lines on the part for different lengths. You can see the bluing on the pictures of the back hub. Once you have all the steps roughed out the fun Begins. I place something bright under the part. Like the paper towel you can see in the background. This lets you see the profile really good. I then rough out the edges. Mainly so I don't have to file so much. Then start smoothing things off with a file. I don't use any gauges or anything to check things. Everything is by "Eye". You can get pretty close that way. If you file one side too much just file the other to match. I think it takes longer to rough out the part than it takes to cut all the roundies on it.

Tips....

Make sure you have a good sharp file.

You don't have to use a "lathe" file. Just a sharp one.

Keep your Rpm's down. You can ruin a file by running the lathe to fast. They work great at slower RPM's!

Make sure your file is clean! If you use a file with those little bits welded to the teeth. They will gouge the part. You'll have to take off more metal then. I use a sharp pick and dig them out of the file.

File a little then look things over. Then file a little more. Take your time! It's not a race! Your doing this for fun right?

Thanks for the compliments!!!

I got slowed down by life this week. But today I got he bolts that hold the rubber in the pedals finished. They turned out great!!! As soon as my wife gets back with the camera I'll get some pictures up.

Tomorrow I'm going to try and get the back hub done. :ddb:
