Re: White lead for centers and chucks
开云体育I have a bud that had a import 8 speed bike . had a generator in the front hub , transmission in the rear hub . They even put a /some capacitors in the system to keep the tail lite lite in case ya stopped the bike for a short period . That bike was much smoother than I remember the Sturmey Archer 3 speeds from way back. I have a vague memory of trying to take a part one of those Sturmey 3 speed hubs & parts & loose ball bearings shooting all over place? , needless to say that hub never shifted gears again . animal On 1/22/24 12:19 AM, Tony Smith wrote:

Re: White lead for centers and chucks
开云体育??? ??? If they can keep them from exploding when charging . I have a guy up where I live unless its snowing real bad & the? roads aren't icey he's out there on his E-bike I've seen him 60 miles from home so much that I don't even think bout it anymore , he does love his bike . I thought about gettin one , but I don't like the exploding/fire option & I'm off grid & didn't want the drain on my system & then I started asking folks &bout theirs & the cost & I put that to bed right then. animal On 1/22/24 7:22 AM, davesmith1800

Re: White lead for centers and chucks
开云体育I left the nice bike world just about the time that Shimano & Suntour were starting to give Campagnolo a run . It was really becoming a hassle arguing with store managers that the reason my bike was on my shoulder is cause it was worth more than most cars in his parking lot . Brass chains were big back then . ??? animal On 1/22/24 12:08 AM, Chris Albertson

Re: Why I Do Single-Point Threading
开云体育Hi Dave and thanks for the chart. If you check the drill sizes across the chart, you will find that it is even easier. For the 75% thread depth, just deduct the pitch from the overall diameter !!! Eg 1”x 8, tap is 7/8” ?????? M6 x,1 tap is 5 ???? ??3/8” x 16, tap is 5/16”???? etc. Works every time. ?????????

Re: White lead for centers and chucks
开云体育Closest would be the 3-speed hub gear.? Mainly found on kids bikes, usually with the shifter on the crossbar. ? Been around for about 100 years, Sturmey Archer is who you need to Google.? I think Shimano make them as well. ? They made a bit of a comeback with early electric bikes before it was decided putting the motor inside the rear hub was a good idea. ? Tony ? ?

Re: White lead for centers and chucks
There were some vintage bikes made with shaft drives.? Quite collectable now.? I think just single speed for simplicity, but not sure. There is at least one modern offering from a company called "Dynamic" that uses a multi-ratio wheel hub. They do exist.? Just very uncommon, I think. Charles E. "Chuck" Kinzer

Re: White lead for centers and chucks
Brings back memories of "cooking" my bike chain in melted paraffin (US usage - wax)? when I was bicycle commuting ;-)
The important part was to put a piece of wire through one end of the chain to make it painless to remove from the molten wax in an improvised double boiler. Roy |

开云体育As I wrote. ?The stuff is not “oil”. ?It is wax is a solvent. ?Oil would attract dirt. ?The stuff I use trades off a short lifetime for being very clean. ? You can also find brands that try to be longer lasting but they are oil-based and attack dirt.Yes, a kids bike might have some oil-based lube on the chain because oil is cheap and will last a long time. ?But more serious riders will want their drive train to literally pass a white glove test and have reduced friction and are willing to re-apply every 200 or so miles. (Every couple weeks.) Boeshield T9 is used in aerospace and is kind of the same stuff, wax in a solvent that leaves water water-resistant coating. My point was that I just happen to have chain lube in the garage and it is designed for exactly what I want, lube and water repellent that nothing sticks to. ? Even lite oil is sticky. ? THis is why you put wax and not oil on the painted parts of your car.

Re: White lead for centers and chucks
开云体育??? ??? It's gettin up in the fine wine $$ range per oz , but it sure is nice when ya take something apart with on there . MY dump truck , is a 1966 GMC . The guy I got it from had no idea if he had ever done brakes in cept for right after he bought if from a county auction , that was @ 72-73 . He used it daily for a few years & decided it was cheaper to
have a guy bring a transfer or end dump they his 5-6 loads to move
the same materiel . SO it spent its year's parked & if needed
he would slide a water tank in the bed & use it for watering
down his roads . When I to check the brakes after he gave me the
truck I bet it was 6 days off & on pounding & soaking till
I finally got all 4 drums off . Kroil was the last hand full of
soaks that finally got them loose . I asked him why he didn't use
Antiseize & he said he didn't know about it at the time .
Antiseize would have made all that work unnecessary . I used open
gear lube when I got my first lathe , took some time but finally I
put a 5 gallon bucket oh the left side of the lathe to keep me
from walkin too close & gettin that crap all over my clothes?
. It is some sticky stuff . I was going to try chain saw bar oil
to see how that worked , but I ended up pulling that headstock
apart & I can not find a replacement thrust bearing for it . ??? animal On 1/21/24 6:53 AM, davesmith1800
