...and so begins the destruction

Getting after the Leadville bike: it all begins with the headtube/down tube miter. This is how I start every frame, no real reason, just feels right. First, the tube is clamped in a wood block at the right angle (60 degrees in this case)- it makes it much easier to hit the right angle if all you have to worry about is holding the file horizontal. Ignore the date on the pics, btw, the camera does this every time I change batteries and I took a bunch of pics before I remembered to fix it.
Four minutes later (yes, I'm a geek and I timed myself) after a little hacksaw work and a few swipes with the b.a.f. (big ass file). You can see I drew what I thought the miter would look like for reference, I don't know why- it used to really help me to cut the miter, but now, I don't really even look at it.

Eleven minutes elapsed time, and the miter is done. More work with the b.a.f. ,followed by an emory cloth wrapped in the headtube, and a few checks with the protracter and we are light-tight baby!

A rarely seen- at least by me- funky compound miter in the seat tube. Notches to clear the downtube, bb shell, and both chainstay ports are visible here.
Next, fire to metal...the brazing begins!
