Adjustment screw stuck in dropout

[Ed no-more-lemons]

Snapped the bloody thing twice in me impatience. tried pliers on the few millimeters that are visible and thought about having a go with a drill(a bad idea?). But I suppose I am just going to have to live with it as it is?

Ouch. That's bad news.

Yes I am Adrian
Only it happens to be a Compagnolo dropout, fortunately the frame has a couple of other flaws so I will be keeping it for my own personal use.

Soak in WD40 for a few days.
Do the bolts have a screwdriver slot. Can you make one?

 

[Ed no-more-lemons]

Snapped inside and out, Doh. I have been trying to clamp some needle pliers on a short internal stump. I was dreaming about some sort of needle nosed mole grips.

What about a reverse thread screw extractor?

A what

Drill a hole in the end of the screw, soak the threads in Plus Gas for a day or two to break up the rust then tap a torx bit firmly into the hole and you should get enough purchase to turn it.

I can't offer anything that hasn't been suggested other than taking care and accuracy if you do try to drill the broken stud.
What I can suggest later is copperslip. I had barrel adjusters sieze in an alloy frame, devil of a job to fix, I ended up drilling them out completely and re-tapping them, then copious use of antisieze to prevent recurrence.

Nightmare people have tried all sorts including spark erosion but usually it's a question of drilling them out and re-tapping. Or glueing them in if the hole gets too big.

Not a job to do with the frame resting on your lap and holding the black and decker by hand.......

While it might be nice to retain adjusters as an original feature of a cherished frame, whenever I've had this problem (1<n<7) I've ended up calling it quits, sawing/snapping/snipping the adjuster as close to the dropout as possible and filing it flush. It must take me, ooh, 4 seconds longer to centre the wheel, compared with possibly many hours trying to extract a broken one. I can live with that!

Is this the same frame with the stuck stem? I'm thinking it might be easier to chuck it in a skip and start again?

If it's a steel screw in an aluminium frame you can use Science and cooking to harmlessly disolve the steel. @zigzag did this a couple of years ago.

Dissolving steel stuck in aluminium ? I like the sound of That, can you link to a thread or provide some more info ?

As suggested - just cut the rest of it out - they really serve no useful purpose - pull the axle fully back in the dropout and align the wheel in the rear forks by eye before you tighten the QR (or nuts if it's an older wheel/hub). Simples.

@User, thanks, that made for an interesting read.
