Well, now I'm a week behind my schedule but I think I'm still ok.

I have a strange fanaticism about getting all the flux out of the tubes to the point where I use a syringe to inject water into the tubes when I soak the flux out just to make sure they are completely full. I vent at the top and bottoms of blades/stays. I suppose i subscribe to the school of thought that air flow helps the tubes dry out after getting wet. I don't plug the vents. However, I don't really like the looks of the holes. Over the past few projects, I've thought it might make sense to drill the hole in the steerer where it would match up to the ports in the crown. I tried that on this build and I think I like it.

Here's a shot of me testing out the fixture and positioning - with the venting through the steerer, this is more critical.


Like the glazing on a donut



Still wet from the bath


Cutting the races:
I cut the races on a lathe and recently purchased a new 25-50mm micrometer. I don't know if I verified it's accuracy or not but after finishing the cutting, I slid a race down onto one and realized that I had undersized the race seat!! Turns out the mic is reading about 0.03mm too big! Luckily only one will need to be redone. I didn't take them all down to 30.02mm, i stayed more in the middle of the range (Cane Creek says 30.015-30.075). Grrr...VERIFY!


Well, a track crown has to have the little arch


I leave the steerer poking through the underside of the crown so i can see the silver flow out and I can blend it in a bit easier.

After cleaning up the underside of the crown:


After some final trimming of the blades to get down to 355mm ATC:



Tomorrow I hope to get the forks brazed up and aligned so I can move on to mitering tubes for the frames.

Thanks for following along.
