BROKEN TAP REMOVAL - Extractor? Nitric Acid?

Anyone have experience removing a broken tap from aluminum?

I have read hit and miss stories about extractors from the brand Walton. I ordered one for $16 that should be here on Friday.

I have also read that using nitric acid is a great way to go. Anyone know where to source some locally? I would love to give it a shot.

I appreciate any help.

I had a broken extractor in a turbo that none of my drill bits could phase. Westside machine pulled it out and retapped it for $30-40.

Tap extractors usually work fine. Go easy so you don't break it.

After you can't remove it with the extractor take it to a machine shop that does EDM and they will get it.

I have had poor experience with extractors - most likely probably due to my inexperience. Instead of having a snapped off bolt in whatever, I end up with a snapped off bolt with a broken off, hardened steel core. Fortunately this hasn't been on any high dollar items like an engine. I thought of this today when I used a screw extractor to drive out a pop rivet after I drilled the head.

Soak it in a lubricant over nite if you can get a fine tip pair of needle nose in the flutes turn it out or use a slot tip screwdriver and hammer and tap it back out....that's right boys

Okay, I spent the last hour clearing the flutes. I can get a small cotter pin through all three, so my extractor should pass through also. If they break without budging the tap, and do not deform, they shouldn't be too tough to remove. Of course, I got myself in this spot to begin with so it's possible I can always make things worse.

I will try the extractor a bit later after I do more reading.

Next question, should I couple the extractor with heat? Heat the swing arm or heat the tap? I haven't done the research on the two materials' coefficient of thermal expansion.

Attached is what I am dealing with. The tap broke as it was moving through the race in the swingarm protrusion.

I wouldn't use heat on the aluminum.

I would save yourself some headache and take it to a machine shop. Won't cost much to have it removed and tapped however if you mess it up its going to be costly.

No go with the extractor.

I never gave it a real twist but I could tell the extractors were yielding. Looks like I will be removing the swing arm and taking it to someone.

All this to only lower the bike maybe 3/4". Starting to feel like it wasn't worth it.

Did you try running it on through with the tap extractor? Looks like you have plenty of room if you can get it going forward. Just twist it back and forth and go with the one that keeps advancing, if any that is.

I gently twisted back and forth until the extractor began to flex a lot and noticeably stretched. I knew they were about to break. At that time I trimmed and tried again. It didn't want to move. Unfortunately, tomorrow I will be yanking the swingarm off the bike.

Swingarm is now in the hands of Westside Performance and Machine.

I ordered another swingarm just in case that should arrive before my moto trip.

I'm about to have to get a couple broken off bolts extracted. Anyone have a machine shop recommendation on the north side? Spring or Conroe would be nice.

I can only suggest Westside Performance and Machine in Spring Branch.

I have the swingarm back in my possession. They got it out for me, and installed a larger set screw.

The backyard playset is kinda nice. How much does somethin' like that go for nowadays?
