Those are great Stew!!! I always like looking at pictures:o)
AdeV:
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?
Powder Keg:
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?
Later, Wes
Powder Keg:
I got the knurled nuts made for my pedals. They turned out great!!! Two less parts to build Yeah!!!
Powder Keg:
Well it was a productive day. I got the pedal spacer tubes almost done today also. 2 more less parts to build\o/ I still have to mill the flats on the small step.
I'm working on the bolts that will go through the pedal rubber now. I have one almost turned.
Later, Wes
