    any shooters in the group??

    I did 30 years ago, but with no place to shoot of my own I was range dependent and I got real tired of the NRA zealots yammering at me. Swapped the guns for a bike and have never looked back.

    Yet ANOTHER tangent.... custom 1910 style English "sloping top tube" Path Racer project.

    Given it's origins out of the skip, maybe the pretender (to the throne).

    Yet ANOTHER tangent.... custom 1910 style English "sloping top tube" Path Racer project.

    Thanks! I missed that over at the other site. I am restoring access to the lathe as we speak.

    Yet ANOTHER tangent.... custom 1910 style English "sloping top tube" Path Racer project.

    Very cool use of what most people would consider, at best, scrap metal. How do you drill the blind holes in the grip blanks? Just a spade bit? A Forstner bit? A lathe tool with a pilot hole? That is a potential project I have coming up.

    The pleasure of the coaster brake, any converted road bikes?

    3 Speed hubs are easy to work on. Watch a couple of videos and you are there. Fine tuning the shifter is no harder than setting up derailleurs properly.

    Covid and bike purchasing

    Do it while you can and don't infect anyone on the way. Mask up and hose everything down, even if you believe it's a hoax. The survivors will thank you.

    Unofficial March Shootout II

    I'm out! Certain family members can't be bothered to close doors and gates in a city infested with criminals and an inert popo "force". I think I will just collect bike parts.

    Unofficial March Shootout II

    I'm in! Not much to modify, but I found this bike for free on craigslist and need to get it out of my garage. I am taking a class next week, so there won't be much progress. Here it is as found: and here is where it sits- new pedals, saddle, bars flipped and a chainguard dropped over the...

    What can any of you tell me about a Huffy Koza?

    The geometry looks stable and comfortable! Even I would look past the Huffy name.

    What can any of you tell me about a Huffy Koza?

    I don't think any Huffy could be used like a mountain bike. At least for long.

    Any ideas for a homemade rear cantilever brake bridge

    The ratty part of my brain says find a farrier and get some used pony shoes.

    Looks TIG welded from here, but you aren't giving us a lot to go on. A picture of the whole frame would help.

    Here's one video- not quite as I remembered it: They are not impossible to take apart. Just consider it a challenge!

    Cottered Chain Wheel into 1 Piece BB?

    You'll have to do some grinding where the ring is swaged in place, and find someone with a good sized lathe to enlarge the hole- concentricity is important. Probably "easier" to convert the bottom bracket to take a 3 piece set, but finding the right axle length can be a problem.

    Mini Mystery Muscle Bike

    Here is a picture of a factory "glockenlager abzieher" https://josef.hammerle.me/part/detail/id/349/name/Abzieher+Tretkurbel and a home built: http://i28.photobucket.com/albums/c221/182grad/Bikes%20Allgemein/glockenlagerabzieher4.jpg

    Mini Mystery Muscle Bike

    Just google "glockenlager" for a lot of information. Basically, they are steel cranks that are pressed onto a square taper axle. BUT and a big BUT, they are not threaded for a conventional crank puller. There is a youtube video that says to remove them, you need a brave man and a big hammer...

    Upper chain tensioner

    It looks like what you need is an idler pulley or sprocket, not a chain tensioner. The idler is not spring loaded- it is fixed to hold the chain in place. A sprocket spinning on a bearing held in a fixed location will give you the chainline you need and not too much frictional losses. A quick...
