Title: Tuf Neck stem - dismantling. Removing shaft from head
Post by: toys19 on July 21, 2008, 04:18 PM

So I want to take apart one of my tuf neck stems to strip the anodising from the aluminium, reanodise and re black the shaft. I have removed the long bolt and wedge, and the four bolts and the cap. I have removed the big short bolt, so now I have the aluminium base piece and the shaft, how are these connected together. I could do wih some advice as I have been very gentle so far and I dont want to muck it up!!!!
Cheers in advance

this is very hard to do!! i found that by putting the stem(body)on top of some blocks of wood so that the quill goes through the bottom of the vice jaws,then heating the body up with a blow torch near to stem bolt works,you need to leave the big bolt in but undo it slightly then whack it with a big hammer-this is the easy bit because any marks can be sanded and polished before re-annodising,the trick is then how to get the quill back in the body without damaging it :-\ i tried putting the body on some soft wood then hitting the bottom of the quill and tried putting it in the vice but found it went in at a angle which you don't want as it takes off some more aluminium then not making it a tight fir any more >:(  i gave up in the end :yahoo_silent:

Removing The Quill

Use a decent workshop press if you have access to one ... it's the easiest way  ;)

Refitting The Quill

Clamp an old seat post or a set of bars in the stem ... use the large bolt to pull the quill back into the stem base  :daumenhoch:

I did mine using a press to remove the shaft and to get it back in; my mate at his mechine shop did it, he also used this low tack tape on the replacement chrome bolt I got and on the stem itself to stop any marks, nipped it up good and tight with the bolt once the shaft was back in situ  :daumenhoch:

Thanks Marty ... that's another pint I owe you now  ;)

The next stem I restore I'll post a thread up with lots 'n' lots of piccies ... maybe the mods could make it a sticky  :)
