Hey Paul, thanks for all the years of enjoyment I’ve had with Romax # 626
After watching your videos I have even more appreciation for all the details that make the bike so special.
I imagine it is in the book from your early years . I ordered it in Imron black, still original paint.😊
Thanks for watching... We both own Romax's!!
4,000 frames or 10,000 hours (at least) = bike making legend Paul Brodie.
At 4:50 "it's a pretty neat system... I know the guy that invented it" caught me off guard! Thank you Paul, and thank you Mitch.
Thank you for sharing. I have learned that bronze fills, nickel silver binds, good flow lasts for a fraction of a second, tacks pull, full scale drawings are useful, jigs are important, and at some experience level eyecrhometers are just as precise as any purpose built measurement device.
I think you're catching on! Thanks for commenting :)
The noodle maker tool is impressive
Dang, so much great content still to discover!
Thank you very much!
Wow.... I think I need a Brodie Bike Frame..!!!!
Sounds like a great idea!
Was headed for bed but had to watch this first. The brazing techniques alone are a masterclass.
Just watching this is like meditation for me, really relaxing.
And I must say that you do great work and possess some awesome skills.
Thank you Albin.
Albin, do not think " too hard for me to learn ". I told myself I would never learn how to weld. I didn't think I had the coordination. Thirty years ago I got a chance to START learning at a premier semi conductor company. I love metal fab and found it is near limitless and never boring. I am retired from building sanitary food process equipment and now too learning MR Brodie's techniques. Today I learned to mix the nickel silver can play nicely with silicon bronze. Thank you MR Brodie.
Well...started riding,racing Road 1968..played a part in the MTB story from early 80’s,worked in one of England’s first MTB Specialist Shops,then back to being a roadie mid 90’s...went from Steel frames,to Aluminium in mid 80’s...to Carbon the past 15 years. Now,after watching these fantastic videos,showing a craftsman at work,creating masterpiece of design,function and beauty out of steel tubing...my next project is the find a steel frame to replace my Carbon MTB Hardtail !!
That sounds like you're coming full circle. Thanks for watching!
@@paulbrodie exactly my thought! also have tiny regret that I didn’t go into frame building..Helped run a bike shop,have worked for a few teams as Mechanic on Ras and Tour of Ulster in Ireland and now have workshop at home doing bike fit,wheel building and custom builds etc but watching your work touches the mark..also was selling sculptures for a while and a good bike frame is a piece of creative art.
@@felixjackson2670 It's not easy making money as a framebuilder, but let me tell you that it can be a fantastic hobby. You will never be bored and it can occupy your mind like few other interests because it encompasses so much.
Omg. Those cable tubes around the seatpost? Soooo cool. I've never seen a steel frame done like that.
We started doing that in 1986, so it must be "retro", eh? Thanks for watching!
I watched your video with a lot of attention to detail…..you are simply the very best……thank you
Very nice compliment, thank you Tony.
Thanks you so much for sharing 😊.. i just watch your all videos 💯 some day i made my own frame 🇵🇭
That would be great if you made your own frame. I wish you the best.
Thanks a lot for posting these videos, it's very generous of you.
I have the attitude that it is good to share knowledge. I know that not everyone feels that way. Thanks for watching!
I have a Romax I bought new around 1990. Very cool video, the tools and jigs the detail, chuffed to see how my actual bike was made!
Thanks Steve.
I found the channel last week, stoked for the new video
Just woke up this goes good with coffee. haha Thank you for this relaxing video!!
Bicycles and coffee do go well together :)
Thanks a lot for this videos Paul! Its being a real master class of Framebuilding for someone like me that I am willing to make it happen
And I thank Mitch; the Man behind the Camera.
A work of art. Beautiful.
Thanks!
keep it up
Отличная работа!
Watching the dropout work was super-satisfying. Really great work and looking forward to seeing her all polished.
Mountain Goat (then Altitude) and others were using a sort of adjustable dropout back in the day. They look nice and fancy but watching this now, I wonder if it was a way to compensate for inaccuracies in a "mass production" environment.
35:02 Love the organic CO2 fire extinguisher. ;-)
top top top belo trabalho vejo todos seus videos até o final..o sr.esta de parabéns..que venha mais videos bons com esse...até a próxima.....
You mentioned your fluxer gurgling, maybe in another video you could show it, explain what it's doing for you, and why it's part of your brazing rig.
It's not much to look at, and it sits on the floor. The flux mixes in with the Acetylene gas, and comes out the torch at a very steady rate. It helps protect the metal from overheating, and really helps all (3) types of filler rods to flow. It's a very wonderful tool for a framebuilder working with thin gauge steel tubes.
The U-brake bosses have a hole in them so you can route the rear derailleur cable through them! At least, I have seen that done. Maybe just a clever use of a hole that was already there, or maybe that's the intended purpose
Yes, some bosses have a hole and others do not. The hole is for routing the derailleur cable. You are correct. Thanks for watching!
Hi Paul. Beautiful work. The little hole in the u-brake bosses is for the rear derailleur cable to run through on its way from the underside of the BB, along the bottom of the chainstay, to the housing stop near the dropout. Cheers.
Thank you Colin.
I can't wait until the summer. I have done a very small amount of brazing and watching you I have clearly been using too much heat.
Putting too much heat on a tube has something to do with the seasons?
@@paulbrodie lol, i live in Edmonton and have an unheated garage so when the weather is nice then I can do it :). The previous brazing I did seemed too hot, the torch was louder and the bronze was too liquid.
I had a Climax because I couldn't afford the Sovereign. Rode it to hell and back nine months of the year. Commuting, the north shore and any errands I had to do. Now I'm looking for a steel gravel bike, to ride until I die.
Hey Paul - It's been fun to watch your videos. I look forward to seeing your brakes! Have you ever made a set of canti's in the past? Thanks for posting all of these.
Great video Paul,not sure if you had mentioned it in a previous video,but was curious as to why you did'nt go with the disc brakes :-)
I'm going with U-brakes. I will make a pair in an upcoming video..
@@paulbrodie Nice one Paul,looking forward to it :-)
I just found your channel and love your work!!! Did you make your air belt sander? very nice maybe you can make a video on it.
Yes, there is a video on both belt sanders. Thanks for watching!
Not bad.......😀
Have you done Belt splitters. BELT SPLITTER not drugs which your hung up on.
I have not. Is that a new drug?
Beautiful work. Are the noodles car brake pipes?
It's the same size: 3/16" OD with .035" wall. I like the good stuff that is not made in China. And thanks for liking :)
Art. Do you need to paint it? IMO only clear coat.
It is clear coated. No paint...
hey paul, why are you brazing some joints and weld others? wouldnt it be better to weld it all? i'd really like to know the reason why you braze the stuff instead of welding it
Some builders do Tig weld everything. It's not easy welding around the seat stays to attach them to the seat tube. I like the squared off ends of the seat stays. That's a part of the "style" I put into a frame. Tig welding them would probably burn off the corners, changing the "look". I can also make the nickel silver smoother than a Tig weld. I hope that answers your question.
@@paulbrodie yes thank you very much. ill propably never build a bike myself, but its truly magnificent to watch a master at work. keep it up for a long time!
Paul- how come the tubing you are using for the noodles doesn't collapse or kink when you bend it?
It is high quality tubing. Actually, 3/16" hydraulic tubing with a .035" wall. Very nice to work with, it does work harden as I bend it. Thanks for watching!
Hello, Mr Brodie. May I ask your seat stay fixture's information? Its really neat system!
Just found your comment. There is more info on that seat stay fixture in the Shop Tour video. Thanks for watching!
Why did you change the brake posts from 30:20 inside to 33:08 outside?
Did you not like the spacing or was it some other reason?
You have a sharp eye! Yes, it was to do with the boss spacing. Thanks for watching!
@@paulbrodie That's why the U brakes had to be different when you made them, Boss spacing wider on the rear.
Utectic
Why do you use nickel silver to sweat the joint before filling over with braze?
Nickel silver has slightly better flow characteristics, and the larger bronze rod is better for building up the fillet. Best of both worlds!
@@paulbrodie thanks! This has become my new favorite channel and is quite inspiring. Just started bike frame number 10!
@@elworm0 Congrats on reaching number 10... You must have learned a lot along your frame building journey!
how do u retram the mill head quickly? u seem to always tilt the head not jig the piece?
I just set the head to zero on the mill scale. I know it's probably not absolutely perfect, but it's also fine for 98% of the stuff I machine. If I'm doing a machining operation on something critical, like an engine part, I will take the time to zero it in using a dial indicator, and get it to a thou or less.
Thanks Paul, btw I just came in from the garage having just brazed a filed my FIRST set of
Drop outs and stays ! I’m coming for ya! 😝😝😝
hi sir i like your work..i really this frame..how can i buy a frame and fork..i like to buy one of your work..
Sorry, I'm retired. Not making frames for sale sorry.
Paul, I saw in a video by one of your Framebuilding 101 students around ~2011 that you have some sort of s-bend seatstay bender. Do you still have it? And could you show it off some time? th-cam.com/video/PTPHbOPJ5gA/w-d-xo.html (at 2:36)
I think we showed it off in the Shop Tour video. Let me know if my memory has faded :)
@@paulbrodie I spotted it in the back corner of your shop in the Shop Tour video but it wasn't covered, or maybe it didn't make the cut? Just the seatstay mitering fixture.
@@squiresuzuki I did bend a seat stay as part of the video, but there was a lot going on, so I guess it didn't make the cut. Sorry.
