Apparently someone that posts here as I remember the implication and sharp drills were only found in machine shops :-) Yep, YMMV, but I've always found it cheaper to just buy a new drill set or collection of drills than fuzing around trying to sharpen them. OTOH, I don't earn my living drilling holes and it rapidly became obvious that as far as "drill sharpening devices" went one size/type/style didn't fit all and apart from a pileof files, that's enough. I'll go as far as touching up a chain saw every cut on dry redgum or yellow box(realraiway sleepers), but life is too short to touch up a drill for every hole. Different strokes for different folks, I guess. But sharpening drills is just two passes across the grinding wheel and a chain saw has a multitude of teeth :-) If you have a shop, then I guess you're bound to have a grinding wheel or three, but no shop here. Nor do i have a vice standing by with a groove to hold drills so I can rub a file over them. Then there is the fact that I just can't file a flat surface for the life of me. Nor can I cook worth a damn. My secret is "I don't cook" :-) By the way, if you can file your drill bits with a common file then you are buying the wrong kind of drills :-) -- cheers, John B. |

We don't seem to have all that pre-cooked stuff here and my wife of 50 years still cooks my meals :-) In fact during the periods when we have had a servant the most the servant was allowed to do in the kitchen was wash the dishes :-) But of course with folks our age, in this country, the old fashioned scheme of the husband supporting the wife (in the manner she has become accustomed to) and the wife managing the household is still common. -- cheers, John B. |

I'm afraid I know many people who see no problems what so ever in drilling holes in frames - literally every custom frame builder I have ever been in contact with will put as many bottle cages on your new bike as you ask for. And every cage requires two holes to mount. Hopefully you realize the difference between a custom frame builder drilling a frame for cage mounts and the owner of a Huffy doing the same. Well, tell us, oh great pundit. Do the frame builders, who often know very little about the metals that they work with, buy special tubes to allow them to drill holes in them? Does Columbus, for example, manufacturer special frame tubes for those who wish to mount bottle cages? I'm pretty certain that you understand that a frame builder adds things like cage mounts to tubes prior to assembling the frame, whether welding, brazing, or gluing. I'm also pretty certain that you know that a frame builder would almost certainly own jig that they would be using in order to drill properly spaced, accurate holes. |

But I've managed to deburr holes for many decades without one. I suppose I could buy a triangular scrapper, but a countersink deburring bit works fine. For small holes there are Dremel accessories with conical tips that can be used. But thank you for making my point. Most people probably don't have the tools to do the job properly. Since I've been building prototypes in steel and aluminum chassis since I was about 12 years old, I have accumulated the tools needed. I still have my vintage Lafayette chassis punch kit https://thumbs.worthpoint.com/zoom/images1/1/1211/10/lafayette-antique-radio-chassis-punch_1_b0bbb287cdd38f4742b8eb3a34687f4b.jpg |

Love this little Israeli deburr: http://www.bartsupply.com/gallery/pr...haviv_tool.jpg I just had a look at Amazon and a Kennedy "machining's tool box is almost $600 :-( Back when I was working at the trade my whole box, tools and apron didn't cost that much and we had to supply our own 1" and 2" micrometers and they had to be either Starret or Brown & Sharp. and a couple of Diamond Debs too. That said, "most people" probably have a crappy claw hammer, a screwdriver with flat/Phillips #2 flipover from the $1 table and a can opener. They don't know how to use the can opener. This is based on my research of being asked to help out with various household problems at various households. Based on those experiences, "no" is usually the best response. Or, "I charge $10 an hour" :-) Or, as I remember seeing somewhere, "$10 an hour and if you tried to fix it first than $20 an hour". Mine was a hundred, about the same as a midprice race frame at the time (less than a Masi, more than a Gitane). Good value IMHO. My Starret micrometer set was a gift from a retired machinist. I had an antique, I guess you'd call it, wooden Kennedy box given to me. I was always afraid to actually use it for a tool box as I was afraid of damaging it. So it just sat in the garage looking pretty :-) I schlepped mine in my MG between two jobs and then home for a couple of years.

snip Ralph already considers me an infidel because I have a Huffy. I can't afford those fancy pants $4000 bikes. :-) But you can probably afford the tools necessary to properly install a pair of Rivnuts. You can purchase all the necessary tools for under $100, and you already may have some of them. Some of the tools you can jury-rig, but don't skimp on the drilling jig. $15 Rivnut insert setting tool: https://www.amazon.com/dp/B01N420A2D $ 7 Rivnuts: https://www.amazon.com/dp/B00NGK6UBY (for aluminum frame) $29 Drilling Jig: https://www.ebay.co.uk/itm/222390828275 $13 Triangular Scraper: https://www.amazon.com/dp/B07DJ61QD4 $ 2 Liquid metal filler https://www.amazon.com/dp/B000ALDYJI $ 2 7mm drill bit https://www.ebay.com/itm/392072184033 $30 Close quarters drill https://www.harborfreight.com/38-in-variable-speed-reversible-close-quarters-drill-60610.html 1/8" drill bit (or 3mm). One thing to be careful about is getting all the metal filings out of the frame after you drill the holes. When Rivnuts are installed at the factory it's done before the frame tubes are welded, brazed, or glued together so the metal pieces can be easily removed. But once the frame is assembled you'll need to shake out those pieces through the seat tube or bottom bracket or headset openings. Or find a custom frame builder or bicycle shop that may already have all the proper equipment, and will do it for less than the cost of all the stuff you'll need to do the job properly yourself. But personally, I'd use clamps. For under $15 you can buy clamps specifically designed for this purpose. |
