  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    That seems obvious to me now that you point it out! that hadn't even occurred to me. I'll look into, thanks.

    My welding challenge

    Yeah I've read on some bicycle framebuilder forums that people like that torch. I am using a 'little smith' torch clone, as I got it for pretty cheap at KMS tools. I think Mr. Brodie is using a uniweld 71 torch or something of similar size. He is using an inline gas fluxer. I have a gas fluxer...

    That’s very kind. I’m sure I could teach you a thing or two about bicycle technology, but when it comes to fabrication I’m sure it’d be the blind leading the blind haha!

    There were a few other steps I missed taking pictures of, but my frame is essentially done and I could throw it together! For now I've robbed all the parts off my other bike while I wait for the rest of my parts to arrive. I'm going to ride with these borrowed parts until everything else is in...

    The crankset I've elected to use can only be purchased with 'single-speed' chainrings. Single-speed chains have wider rollers, so that the accompanying sprockets have wider teeth which makes them last longer. Multi-speed bikes have much narrower sprockets and use narrower chains. To use this...

    Towards the end of the build my brazing skills had improved quite drastically and I was no longer happy with how the water bottle bosses looked which were the very first thing I brazed and I cooked the sh*t out of them (pictured below). I decided to drill them out. After drilling the heads...

    Alright I've essentially finished the frame! Pretty much all of my free time in the last month was finishing up the fabrication. I'll break the post up into a few posts. I had to make another fork which was pretty similar to the previous one, although this one has mounts for disc brakes. The...

    My welding challenge

    Do you know of any reputable and economic oxy acetylene regulators with very low pressure ranges? For bicycle brazing I don't think I'll ever need more than 5-6 psi. I set my oxygen regulator for bicycle brazing by just dialing in the valve until I can just see the needle pop off zero lol.

    My welding challenge

    Does your tig welder have pulse capabilities? I really liked using pulse on my bicycle tubing, although that was ~0.035" wall thickness. I'd second using mig wire as filler. Rule of thumb is for the filler to be no thicker than what you are welding, but I don't know if 0.020" mig wire is...
