Re: possible worm gear & some bike stuff
开云体育Nice job , so is everyone using sealed bearings in their wheels & bottom bracket these days ? A bud of mine was looking at buying Phil Wood many years back but I think something happened with his " partners " that caused the deal to go south . They have such a niche product I'm real glad to see that they are still around . IIRC they only had their product in hi-end bike shops . thanks animal On 3/26/24 2:25 PM, paul mcclintic via

I couldn't get the photos on with the text. The part is press fit onto the shell and the bearing is pressed in on the other side. The axle end caps are pressed on also. I can remember if the bearings were pressed onto the axle or not. I don't think so. Phil Wood still makes a lot of items and is one place you can still get some French, Swiss, and Italian threaded parts that you can't find anywhere else. |

Re: possible worm gear & some bike stuff
开云体育??? So? did? ya make the whole flange ? Any pic's? ? Is Phil Wood

Re: possible worm gear
开云体育Two sizes for pedal threads.? One for kids bikes, one for adults.? Imperial threads, of course, and the difference between them is bugger all (1/16”) so I’m not entirely sure what the point was. ? And I think the smaller size is only for small kids bikes with those one piece cranks. ? But that’s bicycles for ya, make everything different because why not.? Changing handlebar tubes from ~25mm to ~30mm still annoys me, ??Why? ? Tony ? ? From: [email protected] <[email protected]> On Behalf Of Chris Albertson

Re: possible worm gear & some bike talk
开云体育Back in the day if yer bike came with Mafac brakes it also came with a little tool set maybe the size of a pack of regular cigs . That little tool kit & Crescent wrench were the only tools some bikes ever saw during their lifetime after getting bucked in the bike shop . A lot has changed in the bike world since I left it . thanks animal On 3/25/24 5:17 PM, Chris Albertson

Re: possible worm gear
开云体育Another thought is maybe by making a new worm & gear ya could end up with a more user friendly thread pitch that could make the math easier ? animal On 3/25/24 2:05 PM, Chris Albertson

Re: possible worm gear
开云体育Back when I was still into bikes & Campagnolo ruled everyone had to use different threads in their bottom brackets & pedals . I had/have a Set of TA cranks & chain wheels & the threads were different between? TA , to Stronglite , &? Campy crank sets . I was so pissed when my new to me Campy blacktop pedals wouldn't fit the cranks . It's actually probably good that I didn't have a mini lathe or any lathe & mill for that mater back then. I'm sure I would have ruined a lot of expensive parts by fixing them . animal On 3/25/24 2:05 PM, Chris Albertson

Re: possible worm gear
Chris Albertson
开云体育The thing about bicycle parts is that they use a lot of non-common threads and gear profiles and screws with custom head shapes, not to mention exotic metals and tempering. ? for example, you can look at a standard bottom bracket and find?34.92mm diameter threads. ?Not a hardware store size. ?You might measure and?think “35mm” and be wrong. ?? I don't know the specs on the gear you need but, there is a good chance is it a custom-size or profile.

Re: linux off topic

开云体育One reason to prefer Ubuntu is that it is so common, Google will find help with it when you need it. ? ? The other reason is that their “LTS” versions. ?LTS is “Long Term Support”. They will offer updates for many years if you pick “22 LTS”.will end this year.This is not such an off-topic question. ? People are using Linux-based software to drive the mini-mill and less mini-lathe as CNC devices.

Re: Material for riser block
I would try thrift shops and estate sales, looking for likely bits of metal.? I found a 3/4" inch thick by 6" diameter cast iron disc that once lived in the bottom of a lamp.? Probably going to be a mount for a 4 jaw chuck.? I found a pair of 5 pound one piece cast iron dumbells.? about 2 1/2 inch hex by 1 3/4 inch thick weights with a bit over one inch iron rod between.?? One end of one dumbell will be an ER16 collet chuck for an Emco compact 5 lathe.? Part of the handle will be a collet chuck for a little Taig lathe.? Not sure what what will become,? but they were less that? $8 for the pair.?? If you cant find thick enough metal for your block you could stack something thinner.

Re: "welding"
i SEE? SOME HOWRO RESISTANCE WELDING? UTUBE??
BUT? SOMETHING? HAVE? TO? BE SAID? Professional welders have three setups
1- Squize is a short time not to deform the object
We must not weigh for a long time on the Welding Pieces
2- Heat heat 'you have to modulate the voltage to vary the heat; Easy to do with a dimmer
?
3- Hold is that you have to hold the piece after
having welding so as not to make cold welding if it moves a can after applying the heat ALLE? THIS? EQUIPMEENTS? DO NOT? MAKE? PERFECT? ?JOB? IF? YOU? ?DO NOT? KNOW? THIS JACK 47 71 |

Re: Using nitric acid to remove broken taps or drills from aluminum
开云体育Hi Dave. It isn’t easy, as UK sockets have an internal shutter over the power contacts and it is opened by the earth pin. By then the power sockets are not accessible. Also, the switch should be off I have no doubt, that some youngster will try hard, maybe take so long, they are discovered and prevented from ……….. ? ?????????? Ellis ? ? ? The first thing of about 220 volt house voltage is kids and paper clips. |

Re: "welding"
Here are some offerings from Micro-Mark who caters to hobbyists: And you can go to YouTube where there are MANY videos including so for how to build one of your own for low cost.? The two methods used for heating is to attach a lead somewhere on the part and then use a single point probe.? The other is to use tweezers where each tip is an electrode. Charles E. "Chuck" Kinzer
