I'm Mitering (moving right along) now!

So this is moving fast now, Last night I was able to clean up the bottom bracket to just leave a little sanding and mineral spirits cleaning for brazing. And I have to admit I was very nervous about mitering the down tube/head tube joint, I was very cautious in starting and it ended up taking me about an hour to miter this cut and get it to fit flush to the head tube.
I admit I really thought I screwed up when I did my 1st test fit because it was way off, with frustration starting I sat back and assessed the problem. Luckily for me my engineering aptitude (that everyone always says I have) kicked in and I realized that the "waist" or side peaks were way to high slightly misshapen. So I filed them down just a little to see if I was right... yup that was it.

Once I got a nice clean fit, I filed and checked, filed and checked, and filed and checked again. But I couldn't get that fit of absolutely no light shinning through? So I sat back and read a little bit and pondered how serious I need to be with this fit. So I decided to reshape it a little more and see what different filing will do, I fugured when I read so many builders blogs about making sure no light is shining through at these joints then I had better take this serious.
So another 15 minutes of filing I came up with this fit below. It could be better but I feel it falls into the criteria that Tim (Paterek) instructs in the manual and many other builders strive for in their blogs.

Once I was satisfied with the miter I nervously checked the fit between the head tube/down tube and the bottom bracket/down tube... it is so close to the drawing that once I braze these together the BB facing and cuting tool will just barely nick a piece of the tube when it is doing it's thing. You can see in the pictures below how clean the fits are.
Now I basically just have to cut the fork blades (straight legs with plug in drops) and prepare it for brazing as well as prep what Tim calls the subassembly with mineral spirits and some sanding.
Not sure if I will braze this week or hold it for friday night and saturday because I won't have much time tonight and tomorrow night because that is Hannah and me time.

I will be using pins to keep the frame aligned because I don't have much in the way of fixturing so for this frame I will clamp everything on V-blocks (seen in the picture above) and then pin the HT/DT for brazing and then pin the BB/ST for brazing to follow the Paterek build up.

If anyone has any suggestions on pining or clamping feel free to let me know...
