So after some more garage time with my Alloro yesterday...
1. I finally got the crankset off. The drive side arm/chainring was pretty well attached to the square taper. Took some "gentle" heat with the blowtorch and a 2lb sledge to finally get the thing loose. Where gear pullers, prybars, and others fail, the BFH succeeds! and the crankset doesn't look too much worse for wear. Now, i've still got the driveside bearing "cup" (is it a "cup" when it's an internal, square taper BB?) still seized to the BB-shell threads. this is the side with only 2 flat sides to grip--i suppose i'm going to have to either invest in a large box wrench, or find a better adjustable wrench (i HATE adj wrenches). also, either my measuring tapes are nuts, or i've got a 69mm bb shell. not 68, not 70, 69. either i don't know how to use my tape (which is actually confirmable once i tried to draft the bike's geo using the measurements i posted above...comical to say the least) or i've got yugoslavian BB threads, haha. Internet research tells me that 80's alloro's are italian threaded. can anyone confrim this?
2. The stem is off and the headset looked awful inside. plenty of rust (from the headtube?), dirty bearings, not a smidge of grease left in the bottom bearing. the top bearing isn't much better. some WD-40 and a rag shows the bearing cups aren't in terrible shape, and the balls don't look bad either--better than the BB bearings anyway. Any ideas on headset choices? Campagnolo for authentic Italian flavor? Tange, for the "I don't care, I just wanna make this thing ride for as little money and headache as possible" side of me? The stem itself looks pretty cruddy. Stem bolt was covered in some strange chalky brown paste that didn't look like rust, and the stem plug was pretty nasty as well, with lots of rusty gunk on it. i think it's salvageable, though i only performed a very cursory inspection of it.
3. When this frame gets sandblasted, will they be able to get the interior of the tubeset as well? there's some rusty spots inside the headtube, BB-shell area, seatpost, and i wanna make sure i can get it all if i'm going to take the time to repaint.
4. Just scored a DA 7800 group that i'm not sure how to use. Restore the original campy/modolo/ofmega components? or go "retro-modern"? If i don't use the DA here, i can use it elsewhere.
