Assembly strategies
https://www.italiansteelbike.com
Has a few embedded videos, the 1972 Masi GC assembly shows a different assembly of the bottom bracket than I have seen before.
There are some short cuts that might cause a return visit later, not lubricating the brake springs at the arms, and possibly the levers too.
‘Many here would be aghast at not removing the tape residue below the brake levers making lever installation more work than it should…
Who knows what is in a spray pressure gun shown in one of the clips.
But the bottom bracket assembly, while truncated a bit regarding fitting the Campagnolo inner sleeve, note that the drive side crank arm is secured before the bearings are adjusted.
that I imagine does allow to verify that the spindle is not assembled with play, not how I do it but I am always evaluating for a minor hitch in the rotation.
On one bike that was stated to be “perfectly assembled” it took two complete tear downs to obtain rotation perfection, dirt can hide in those caged bearings that even are ultrasonically clean.
On that one I had to remove all the bearing balls, clean the parts one last time…
but worth a look, the order of operations are there, my guess some of the basic strategies are common.

Nice selection of bikes, and frankly, I didn't see any glaring errors on the bikes for sale; Cinelli bits on a later Colnago, Etc.
To me, the prices seem in-line with reality. The Cinelli cost a little more than the DeRosa which was a little more than the Rossin.
I agree on it strange to install the DS crank first, but maybe that allows for a better feel of play with the leverage of the crank arm.
Only thing that made an eyebrow to raise was the tires with pre-cracked sidewalls.

After the video, there is the option of watching more. That's where it is.

Interesting site. His investment in a fleet of classics for sale makes me feel better about my own collection.
Some creative license being used to describe the bikes. Calling the Berma a "Berma Professional – Campagnolo Super Record" when half the components are Chorus is a little funny. Other small details like replacement dome nuts on SR brakes, a 1993 Bianchi with Deltas...small gripes.
I'll go finish my coffee now.

@repechage - Thanks for the direct link!
- He must have used caged bearings for the BB install and they were placed in the cups prior to installation.
- I did not see ferals on the ends of the brake housing going to the levers. Is this the accepted assembly? I have used them on the Bianchi, and they don't fit in the lever base making that interface wobbly.
- A lot of confidence to cut the cables that short!
- One large roll of HB tape and only one wrap around the lever band.
- Looks like a 65-xx HB too, which I am learning to appreciate.

Masi also used tape from a big roll, if you know the bar configuration, can avoid waste. Easier as the radius wrap of the tape is bigger for the most part. Newbaums sells it that way.
‘not sure of the brand here.
no surprise for Campagnolo caged bearings.
ferrules, not sure, they can be preloaded, the video has some bypasses and edits.
no grease or anti seize on the seat post…?
bypass that pesky adjustment of the Campagnolo seatpost to saddle.
open end wrench on the brake cable anchor bolts… the T wrench is the way to go.
maybe one day I will make an assembly video, but that would be telling.

Mounting the bottom bracket is the first thing I do, even before installing the headset bearings. In the video, you see him stoop down to install the bb. It's far easier for me to keep the bare frame on the workbench while I'm doing that.

a case can be made, maybe run with the work stand one has. Do those squats.
‘there are a few skips, unclear to me the security of the arm, implying lateral load to assess play, OK, but might miss that perfect adjustment.
‘the shown assembly scheme was just interesting to note.
short power outage here. Wet weather

It looks like the fork is resting on the bench when setting the crown race @ 0:52 . Good way to chip the paint or even bend the dropouts. I was taught to never do that but perhaps I am wrong.

yes, if the interference fit is good, just holding the fork in the hand and using the Campagnolo tool as a slide hammer gets the job done pretty well. Campagnolo tool kit even has a passa/ no passa gauge for that.
