Removing cable guidesContinental

Does anyone know a good way to remove brazed-on cable guides? I'm tempted to heat them up with a torch and yank them off.

In the 5 bikes that had them, that I have converted to fixed over the years, I just ground them off with a rotary grinder and finished them up with a fine file and sandpaper. This necessitated the repainting of the frame, which was a planned item of expence. I think the wisdom is that you should avoid the use of heat to any of the joints that are already brazed. Which makes my method the preferred one for removing the guides from headset joint that is the way a lot of the newer frames come from the mfgrs. The guides that are on the tubes are probably safe to use the torch on, but I think the less heat the better when it comes to bicycles. It is more work to do it by hand with files and sandpaper but it may pay off in dividends of not having to have your frame reconnected at the joints due to deconstrution due to overuse or incautious use of heat.

I used a Dremel tool and first cut them off with a cutting wheel, then filed them down, and finally used a fine grinder (all attachments on the Dremel) followed by touch up paint... not as smooth as sanding but it'll do until I repaint the bike (if I ever do).
that's what I would doDougSloan

Haven't done it, but the Dremel tool is what I would do. A big grinder might heat up the tubes too much. Also, get the heavy duty Dremel grinding wheels; this regular ones are too fragile.

I have resisted the urge to buy a Dremmel tool for low these many years. It seems that many people use one. I guess I should go ahead and bite the bullet and get one. What model is the better and what tool bits or whatever they are called are useful? Inquiring mind want to know.

I have the "Dremel 3962-02 Variable-Speed MultiPro Tool Kit" and it has lots of cutting wheels and ginders, etc in the kit. I like the variable speed because I can slow it down for fine sanding work. It's fairly intuitive to use. I also used the metal cutting wheels to take off my rear derailleur hanger and all cable guides.

Thanks, I am somewhat of a retro-grouch when it comes to tools. I love hand tools and fear and respect power tools after a long career as a carpenter/woodworker and having seen some truely horrific injuries while "on the job". Usually the most that can happen to you is that you can get cut by a blade on a hand tool. Discounting, of course, the smashed thumb via the inappropriate use of force on it with a hammer. I have also found that using dull cutting blades of whatever stripe will give you a much more nasty cut than a super sharp blade. I will put on file the information for perusal by my wife for gift giving ideas at appropriate dates. Birthday, Christmas, or as she likes to say, my patron Saints day , "Saint Asshole's Day".

Any suggestions for guides that route cable through tube?Dad Man Walking

My fixed gear bike is a converted 80's road frame that routed the rear brake cable through the top tube. The braze-ons are little "tunnel entrances" that penetrate the top tube. Any suggestions for this?

I am currently having a bike like that converted to f/g and I am having the cable routing tube removed and the holes brazed closed. This is a radical solution but as the bike was having other welding done on it at the same time, it only added 15 dollars to the cost. Then the whole frame is being repainted. One thing that I thought about is if you were creative with a very small paint brush or decals you could depict a vortex at the forward entry hole and various kinds of multi/geared bikes tumbling into the hole, and then miniture flames exiting the rear hole. The possibities are endless.

I agree with the others on using a file and/or dremel tool. It worked for me, but I didn't knock it down too far. Instead of repainting the whole frame, use some fingernail paint that is close to the bike's. It doesn't have to match perfectly since the area is small. I'm lucky enough to have a 14 year old daughter who's chrome purple is an excellent match for my bike's metalic purple. She got a kick out of my borrowing it!

Is nothing sacred any more, Chrome purple indeed. A color best left to teenage daughters, along with bare midrifts and bellybotton rings.

I also find my teenage daughters fingernail polish arsenal a great source of touch up paint. To get a closer match on my "purple haze" Bianchi I rolled it into Lowe's to the paint department and had them play with colors to match the frame. They had a great time involving 3 sales people, about 45 minutes of time and I walked/rolled out with a $7 can of outdoor enamel that was almost a perfect match.

If you are anywhere near a good hoby shop that sells model train sets and all the parts that go with that, they usually have a truely amazing supply of small bottles of colored paint to use on all those little things that train buff make into small worlds and run trains thru. I have found some perfect matches for various bike colors and the bottles are small enough that you can try different colors out without going bankrupt in the process of getting it "just right".
