Cutting off Derailleur hangers. gotta do it....
I'm a fixed gear nerd at heart and want to know the best way to remove the rear derailleur hanger. Is it best to use a Hacksaw, or just bend a few times to crack them off? I want to do this to most of my collection. Oh, and throw out all those Chrome forks and install some of those Stylin' Carbon Forks.

I've found that the best tool to remove a derailleur hanger is a butter knife.
The problem I've had ever since then is that the derailleur now flops all over the place.

I just gnaw them off - seriously though - I have a couple of gas pipe frames (sans hanger) that I would gladly trade for those pesky frames with the hangy-down thing.

you know what, given your usual standard of workmanship you could possibly drew a frame in a good way, with fresh paint, a smathering of beautifully polished campy parts and whatnot...

I take all mine to the pipefitters downtown. They torch it off and throw the frame up on the bench to grind the splatters off.

I cut mine off with an antique Henry Disston and Sons nail saw. It has the most beautiful applewood handle. My wife likes to put the chrome Campagnolo hangers on her charm bracelets. Life is good.

I've never been known as a finesse kind of guy. I prefer to clamp the frame in a bench vise and go after the hanger with a vice grip. Another favorite is to twist it off by inserting a stout screwdriver, or chisel and twisting it off with the aid of a cheater bar.

You should never remove the hanger part of the rear drop out on a good frame. I did it once and nothing happened, but I grieved for a long time for what I had done. Bikes have "soul" and blah, blah, blah.

Safety First.
You probably go with some thermite before going to C-4.
Try the Thermite, then gnawing with front teeth (do NOT use the back teeth- you can damage the molars on such hard substances- the incisors and canines are much more resistant to metals up to titanium).
If all else fails, get a 6 year old with a hammer.

I take my frames to the Great Salt Lake, dip the dropout just hanger-deep in the water, then sit and wait. If I work in batches, I can do about 10 frame in ten years.

I wait for the weekend, take my bike over to Penn Cycle, and ask some teenage kid with attitude working there to adjust my shifting. Then I walk across the street, get a coffee, and stroll leisurely back. Upon my return the derailleur hanger is kaput, and Pimply McSneerenstein tells me that because they couldn't quite adjust the shifting to their usual sloppy standards, this 'repair' will only cost me half price today, and maybe I should buy a newer bike, y'know?
Works like a charm.
(Edited to add: And for no additional charge, he'll break off the limit screws on your rusty old Suntour V derailleur, too.)

I had good luck using a large bolt cutter on a Cinelli. Pretty much useless weight and good thing the Campy dropouts are soft and cheap.
edit: DO save the part. You can always JB weld it back on.

Depends on how much of a rush to get it off.
Quick way, I bungie cord the frame to my pick up truck and drag the hanger on the street for a couple miles. I learned that tip from Grant Peterson.
Who needs a grinder, it comes out great. And the kids love the sparks.
Slow and cheaper way, I dip the hanger in a bowl of Coca Cola for a week. Like a tooth, it simply dissolves the annoying protrusion.

I'd start with that old Carlton of yours. It's totally obsolete and very lacking in pedegree but would make a *****in' fixie!
