some work done... some more info found...


work done

so, just after yesterday's post, I decided the dropout repair was the primary thing to focus on, since that would determine the rest of dealing with the RIH and disposition.

After some examination and thought, I came up with 4 stages which needed to be done.

1. untwist and bring RD hanger in alignment with lower dropout arm - gross

2. Because the the lower dropout actually had 2 bends in it; start bringing the lower dropout arm back up into proper orientation with upper dropout body.

3. Shape a hardwood block to fit in and properly 'space' the dropout gap, when I make the final 'adjustment to bring the entire lower dropout arm back into alignment.

4. Make any needed final adjustment on the RD hanger portion of the lower dropout arm.

won't go into the deal of each process, and did finish thru Stage 2, the result in the image below...



stage 2 of repair - but rideable..

as noted, it is rideable... I also did further work on the Tiagra RD to get it re-aligned and shifting properly - now smooth as bud-da... but still will be replaced...

Took it out in the afternoon for a quick 25 mi. - moderate pace, small hills, a little bit of climbing and descending - I Likie !!! rides very nice, quick handling, good road manners!



well seasoned bike and motor... LOL!

now onto repair Stages 3 & 4... will report back


more new info found....

Found in BF, in a post by @non-fixie regarding another RIH, which has all the same characteristics as mine...

RIH Model Campagnolo Rebuild

all the same braze-ons, same 'unique' placement of bottle cage mounts, same lugs and fork, even the same stem...
so maybe mine is a 'younger' frame than I thought, could be late '80's - early 90's ???
looking at serial # on headtube lug, the 4 digits are in pairs 79 space 47 - significant ??? don't know...
any ideas, thoughts out there ???

Thx
