I admire your patience and skill, I am always trying to improve mine even on mundane tasks. I think it’s good practice for the important stuff. I enjoy watching your method for solving problems in the process and the fact that you don’t just accept something that’s not what you envision. Mitch does a great job capturing what’s going on too, probably helps that he has built at least one frame since he was your student. Great job guys!
The old MAFAC cantilever studs were swaged to their brackets and you were supposed to braze the two together on the inside after brazing the bracket to the blade or stay. Some of the current studs have machined brackets, but the ones in this video look like the MAFAC type. I recall my first Fat Chance, bought in '85, had MAFAC bosses TIG welded to the frame and they had not gone in with a torch to braze the stud to the bracket afterwards, so the studs quickly loosened up on the trail. Luckily, I didn't have the money for custom paint in those days and so it was a trivial task to go back in, braze the studs, and touchup the gloss black finish.
If your canti bosses are old-school two-part ones like Paul uses, the cylindrical part is weakly staked to the square base and must be brazed there or you risk the cylindrical part coming loose later. I assume Paul knows this, but he didn't show that step. If you TIG the bosses to the blades, just hit the joint between the two pieces with a little dot of weld, maybe two dots one on each side, doesn't need much. I always braze there 'cuz it looks neater.
Hello, Paul and thank you for your videos on brazing, silver soldering welding and lathe and mill work they are very informative and educational for us wanna bees.😃 I do have a question though have you ever done a video on gas welding aluminum like a fuel tank or a oil tank something you might have done during your RR habit or even on the Excelsior builds. I really do not want to add a AC TIG to my collection if I have something that will work with some practice of course probably a lot of practice 😢. I know it was common before TIG was around probably a lost art now unfortunately. If you could mention this or even give it a try we all could learn together in a future video. If you have done this already please point me in the right direction. Sorry for the l o n g comment. Thanks Carl
Paul did a lot of aluminium welding in past videos. Like an oil tank for a Excelsior. Start binge watching for a lot to learn including your question. Best! Job
super. As always, it is very interesting to watch the work of the master. Please tell me if you used another flux paste for soldering crown race with nickel silver solder?
I was kind of wondering why you didn't use a weaver clapped on to the fork leg when you're trying to cold set it to the right spacing and alignment. My first expensive bike frame that I bought bare was a Kona Hoale titanium made by Sandvik from The Bike Cellar on West 4th. I was having trouble with the shifting on it, and I noticed that the derailleur pulleys we're not in parallel to the wheel rim, so the derailleur hanger was misaligned. They tried using a regular Park alignment tool but could not budge it due to the spring back of the titanium. The ended up adding a 6 ft extension so they could leave it enough so that it would come to rest in the correct position
Amazing work, but please, please use some local area extraction and a PAPR mask/air pack. We all want to see you in good health, and the flux/metal vapour fumes won’t help with that.
I don't know of any long-term effects from brass (aka "bronze") brazing, do you? Yes zinc fumes can kill you but only in much higher concentrations, like foundry work, not brazing. That said, I did wear a respirator when I was brazing all day. But a few minutes, no problem.
I like the way it looks regardless of the function it serves. I made a triplane fork once because I wanted one then I had to build a frame around the fork. Pacenti fork crowns are a biplane style that is absolutely stunning. I once held a Pacenti crown and told myself I should build a bike around that crown. Pretty tandem in the garage now.
The purpose was to fit balloon tires, with "road bike" blades. There was no crown available that was wide enough back then. Early MTB builders went to some insane lengths to make a wide enough fork, like machining them out of huge blocks of solid steel à la Joe Breeze. Tom soon ditched this finicky biplane design for his Unicrown once he figured out how to do it.
Not a Ritchey invention! Paris Cycles (London) were doing an almost identical crown on their lightweight framesets in the late 1940s, and they probably copied the design from some builder in France who was doiung it pre-war. Anyhow, great work. Keep being fussy!
Another great video. It's great to see you healthy enough to do the bending of the legs, Paul.
Thanks Mark. Yes, I am getting stronger, but it's hard to gain weight.....
Season greetings to you both .
Paul prayers to you for better health .
Thanks John.. Happy New Year to you as well....
Internal flueted steerer tube...that's a first for me. Amazing and rather extravagent!
Hope you have a good holiday season and produce some more supper informational videos.
Thanks Timothy... All the best to you in 2025.....
I love the beauty that evolves from these hands. And actually, I imagine a bike, brazed, but not filed.... wild!
Thanks. Yes, I really do enjoy making things, even after all these years....
You're looking strong Paul, great to see. I'm excited for the Gold Star!
Thanks! Yes, I am excited about the Gold Star too!
Beautiful craftsmanship Paul, we're still the man 🎉
Thanks Salvador. I do my best in the shop!
Santa didn’t drop a new Brodie under the tree for me but did drop another great video. Great work as always
Thank you very much! Happy New Year....
The Master is back! Happy and Thankful to see you Looking good and strong.
Merry Christmas and Happy New Year.
May it be a good, kind year❤️
Thank you.. Happy New Year to you as well....
Nice goldstar Paul
Thank you Paul and Mitch, Happy New Year
Thanks for watching.... and Happy New Year!

Thanks Gordon.. I'm still learning and still making mistakes! It's a never ending process, I believe..
Thanks
Thank you Chris.. Happy New Year!
You are welcome and keep up the great work. Inspirational for me as I start the restoration of a 1976 Ducati 450 Scrambler.
awesome! Looking strong on the vise alignment,handling some leverage. So informative to see how it happens,thanks so much
Thanks Craig. Yes, videos really do have the ability to show how things happen in my frame building shop....
Great work! Greetings from germany
Fe file foe fork... 😮 i smell gas while you braise the your work!
😂, happy year 🕛

Goldstar! Wow! I'm stoked for you Paul! All the best for 2025
When I was serving my machine shop apprenticeship I asked for gloves and got yelled at 😊 keep up the great job 👏 👍
Great video Paul and Mitch. Happy New Year!
Thank you.. All the best to you in 2025!

Hope Santa was good to everyone your end , and Happy New Year to you and the mighty one.
Merchandise: I'm watching this wearing my new It's Milling Time hoodie! Even my partner likes it, which is high praise indeed.
Nice work Paul! What glasses are you using to braze?

Another superb video , looking good Paul
Cheers Chris
Very educational video, thanks for sharing 👍.
Those brake posts weren’t smokin’ hot, they were just excited to be added to such a sexy fork!
Wow, when did you get a Gold Star?
Nice, I'm envious
Thanks to you and Mitch for all the great videos. Really looking forward to the Gold Star videos as my son recently acquired one.
18:55 - Yeah that's not terrifying or anything.... I'd probably just stand there watching you like 😳😬😮 the whole time. 😂
I did enjoy this!
Tank you sir
Wow, your first time doing canti bosses!
Hey Paul, great work! Was just wondering how you jigged up the cantilever bosses? I'm also planning my first canti frame and fork soon. Thanks!
Do you make a Red Baron Fork 😮
Paul, is your gas fluxer active when you're using paint on flux?
looking great. isn't it a pre-war design, rather than Tom's ?
Yeah if you mean the Boer War (1900). The basic design is from the 19th century.
Bi-Plane Boss! Bi-Plane!
😎👍

If you would please explain the purpose / function of this design. It similar to forks I remember on Huffy and murrays of the 60's and 70's.
I like the way it looks regardless of the function it serves. I made a triplane fork once because I wanted one then I had to build a frame around the fork. Pacenti fork crowns are a biplane style that is absolutely stunning. I once held a Pacenti crown and told myself I should build a bike around that crown. Pretty tandem in the garage now.
