I'm amazed how you've just spur of the moment you go to your parts bin and fabricate an entire bike of your own design.
Thanks James. You have to remember that I've been making things out of metal since I was 12 years old, and that this is frame number 4271....
@@paulbrodie You must keep pretty good records to know exactly what the frame number will be
legend!!!@@paulbrodie
Now this is what experience and amazing craftsmanship looks like.
Thank you very much!
Always a treat when you upload a frame building video thank you Paul
Thanks for watching....
Mr. Brodie you make it look so easy and Mitch you never mis a shot!
Thanks for sharing your knowledge I sure do appreciate it.
Thanks Rick.. Appreciate it!
I could watch these for hours and hours! What great craftsmanship! Thank you guys for putting these out!
Thank you very much!
Thank you for making these videos and showing us your craft. I can only imagine the hours of hard work you have put in over the years, to make this difficult skill look so easy. Your frame is also remarkably beautiful, I imagine that it will ride just as beautifully.
Thanks for watching and commenting...
Hey Paul, and Mitch, yes, I agree with james simpson. You're amazing! I really admire the way you finesse the stays into place with the delicate job of filing to shape. YOU'RE BACK!!!
Thanks Tom! Yes, my health seems to be holding and I am thankful for that....
I've never been to BC but you pronounce words as if you were from New England (primarily New Hampshire USA). Is this typical BC/Vancouver accent? Also do you like Inch-pound-seconds or metric?
I was born in the UK a Long time ago. So, I do not have a typical Canadian accent. I like metric and Imperial. I am used to using both. Thanks for watching!
I started this evening with the thought: I wonder what Paul Brodie is doing. I found the gravel bike and I couldn't stop looking. It's so exciting to see someone who knows what they're doing. Thank you so much.
Thank you too. That's very nice of you to say that I know what I am doing...
Wow some crazy skills and experience there. You have the hole bike building mastered very long time ago,not just make a perfect bike,but fast and efficient. Those 2 last parts are hours and hours of labor and dedication. Very nice video!
Thanks very much. Yes, I have put a few hours into my craft :).
My favorite moment is when you put the wheel on after the stays have been tacked to check how things line up. Nothing beats putting the wheel on the frame for the first time!
Yes, it really is one of the true tests! Thanks for watching...
Beautiful work!
May I ask a queation, that if TIG weld it then braze on top of the weld, would that make the joint even stronger?
Thanks!
Not really. Brazing, done well, is incredibly strong... Thanks for watching :)
you should have another channel where Mitch builds and you're behind the camera
I have suggested that to Mitch, but I can't seem to get him interested....
there`s a wellspring of skill and artistry in front and behind
the camera ,looking good dynamic duo, thankyou both !
paul you`re looking fit as a fiddle 😎👍
Thank you. Yes, Mitch and I are a good team...
Eyecrometer lol, love it man. I inherited mine from my dad. It also works as a level which I'm sure yours does as well =)
Yes it does! I have developed mine over the years. Thanks for watching!
That was a lot simpler than I thought it was going to be to make a curved bridge.
'Eyecrometer' 👍 love it.
Do you bother to align the weld on the mild steel tube when forming or doesn't it make any difference?
Do curved tubes have more flex and a more comfortable ride or is it mainly for foot clearance and aesthetics ?
love that lamp base made out of a cilinder head!
Thanks! That was made by my friend Mike Freda. Check out his TH-cam channel!
Nice to see how you work it out with paper and pencil rather than leaping for the CAD...
Yes, call me old fashioned, but paper and pencil has always worked for me.. Thanks for watching!
Good news, bridge tubes for stock, must mean more frames coming our way.
I'm not sure about that. I think I'm averaging about one frame a year lately... but thanks for watching :)
Another great episode! Thanks Paul and Mitch.
Thanks Mark...
That is an amazing build. I always struggle when bending stuff and trying to fit it precisely. Also you have those difficult multi angle miters to get right. Great to see a bike frame built though, its something not many of us would consider in this mass production world.
Thanks for watching and commenting!
Frame is looking great with both ends finished and those wheels fitted. The tan wall tyres work well with your black rims. Thanks for explaining the details of the design & fabrication, you do make it look easy 😎
Thank you very much!!
Great to see a Master of his craft at work and really enjoying it. Still looking for a really good "Eyecrometer" after all these years🤔🤔🤔
Thanks very much!
Brilliant series on the gravel bike frame Paul some of your techniques here and on other videos have been immensely helpful on my pre 1965 trials bike build.
Thank you. Glad some of the info has helped you out!
Amazing skill and knowledge, thank you for sharing.
Thanks Michael...
Paul, hello. Thank you very much. Thank you very much. I've watched almost all of your videos. I really got very critical information from you. I built my first cargo bike in my own workshop, thank you
Your workflow is meditating 🙏 ❤
Thanks so much!
I love this videos, I don´t have the tools but I have order a custom frame (Yo Eddy Ti ) and this videos sow us how much effort is required to make a frame and that is why I have decided to go custom: custom to my size and ride. The design is not easy nowadays. The geometry is a chaos ... 66.5º front angle for XC ... Not easy task to find the perfect ride but I think I will have it.
👨🏭👨🏭👨🏭👨🏭👨🏭👍🏻
Can you talk a bit about what considerations are done in regards to angles when in comes to frame size? What stays the same, what needs to change, are there any relations that need to be within tolerances?
I'm a rather short roadie, and I've always liked responsive bikes, as far as to them being twitchy. But whenever I take my MTB off road, I'm out of my comfort zone fast as ever.
I know this can be compensated with slacker angles, but how much is cracy?
The reason I ask is because I want to build a gravel bike out of an MTB but I don't know what to look for. I'd rather go a little bit slower on gnarly tech than to have a sluggish bike.
I am also not used to calculating with stack & reach as measurements, are there considerations to make with type of bicycle here? Finally, I have no idea how to compensate for the extra reach of a drop bar, how should I dial my position.
Your skills and teaching are the best I've found on TH-cam. Amazing work Paul, and thank you Mitch for documenting this Craftsman.
Thank you very much. Appreciate your comments...
this should be GRAVEL BIKE Build masterclass
That sounds like a Grand Idea. Thank you!
came across your channel by accident and absolutely love these frame-making videos. keep it up
Hi Paul, great work on the bike and I'd like to add: You also seem to be doing well, that's good to see!
Thank you. Yes, a lot of my energy has come back!
Hi Paul I hope that you are well, I have a quick question for you. I am from the UK and a long time ago trained in all the aspects of welding soft soldering and brazing, as I understand it when creating fillets with brass rods you cannot build up material with a brazing rod because it flows like lead solder, you have to use the bronze rod to achieve the build up, and is called bronze welding not brazing or are you using a new rod that has a mixture of the two ? love your work great skill.
Hi Paul. I am considering getting an arbour press for myself and yours looks like a good size to be quite useful. How many tons is it rated for? Thank you.
I like the paper trick and might steal that for my next (hobby) build. Seat stays always take way too long for me.
Great hand skills and craftmanship and very well explained!!
One day i will try to make a frame like you ❤️🚲
And I hope that comes true for you.... It really is a great hobby :)
It is very interesting the way you use the center off different axe's to report on your drawing for the next part to be craft, in a different point of view. Very clever and usefull. Thank you😎
Real Craftmanship 😎👌
Thank you!
Cool build, I'm curious why you chose to use brass filler for the welds and have they ever broke?
who is Mitch and is he even a person? Keep up the amazing work Paul!
Is the rear right dropout UDH compatible?
Who makes a good red-penometer? I'm not confident the one I have will get the job done.
The eyecrometer is best!!
Master class, thank you for sharing your process.
Paul thank you for sharing what you do. I'm not a bike builder but I do some fabrication and the attention and time taking on details matters and you make it a part of the process not a after thought. Your a fantastic fab guy and teach very well
Thank you Jim.. Appreciate your comments..
Bike is looking great.
Thanks Tom :)
New shirt please:"I can eyeball that!"
Amazing 🤩 nice work Poul.
Hey! It is so great to see you back working again 😊 By the way, what is the situation with Tiger cub?
Thank you. I need to get the carb tuned on the Tiger Cub and do another startup video... Stay tuned!
@@paulbrodie I will 👍
Looks good roughed in. Excited to see it all built up.
Thank you...
*_Eyecrometer? Does Starret make that?_* 🤣😆
I'm not sure. If they could they should...
Moore & Wright ?
Eyecrometer is the tool you can't buy with money but with experience ;)
💛💛💛💛💛💛💛💛
Beautiful work of art. Every part is falling into place like it is supposed to.
Couldn't agree more! It's a good feeling. Thanks for watching.
Paul, freeking awesome looking bike !
Very kind, thank you!!
That’s a really sweet looking bike❤
Thank you James..
My most anticipated upload on TH-cam!!! Thanks Paul. I hope i can start building by this year...
The drawing process is begging for a drafting table.
Takes up too much space when your not using it but the pulleys and wires will be similar to brake cables 😉
Amazing work.
Thanks so much!
Love your light!!
@28:43 "Eyecromoteter" haven't heard that one before 😂 My brother who is a plumber calls it the laser eye :) Thanks Paul and Mitch 👍
It's a pleasure watching you work on the bike frame. Thanks for sharing 👍.
I find your delivery very relaxing. Thanks for letting me hangout with you!
great job Mr Brodie, glad to see you back at what you luv,,you are an inspiration,,
Looks fantastic!
Thank you sir
Beautiful quality work as usual
Live it. Love it!
another great video , you realy do have a great way of working , very methodical and some very well thougt out jigs and fittings for holding parts .
Love your work
👏👍👏👌
Legit.🤘
That frame is gorgeous Paul. Thanks for sharing!
I even like the way you "draw" your 8s and 5s !
Superb workmanship Paul
How much would a lack of bridge tube affect the character of the bike? Would it be a minor change in rigidity and feeling, or major? Can’t wait to see the finished bike.
imagine you have really small diameter SS. Without the bridge, under compression (the main force that SS will have), these SS will tend to bend. If you put a bridge to those hypothetical SS there are less likely to bend, hence you will have a less vertically compliant bike. But if the SS are big in diameter and thickness they would almost feel nothing, so putting a bridge there will have no effect. Having said that i saw MTB without bridge frames failing in the inner part of SS in the ST. Compression forces in SS in MTB (as in big jump bikes) are way higher than in road or gravel. Makes sense?
@@andresarregui3417 makes sense but I’m referencing the chain stay bridge Paul installed. I don’t have a steel frame to look at, but I think most steel have them. My aluminum frame Trek does not. My carbon Giant, that area is boxed in. I think it would most affect bottom bracket sway when pedaling.
@@hordboy Same principle but think of a sideways (rocking movement of the BB in a perpendicular axys to the plane of the frame) force. If not done correctly (big fillet or another way to not have a step angle of the bridge with respect to the CS) you have a big stress riser. If you have massive CS bridge wont affect. Even with old school steel small diameter tubes it will be hard to say how much stiffness the CS bride will provide. Unless you want to use fenders it could definitely be avoided. I saw lots of frames cracked in fatigue in the CS bridge at the side of the drop outs.
So going to your original question depending on your set of tubes but probably you wont feel anything. Think of all the other factors that you can actually feel, like pressure of the tires, thread of the casing, type of wheels, type of cranks, henadlebar, etc... CS bridge influence in character of the bike will go in the lower part of the list!
excellent vid thanks, camara work is getting better all the time
hello from russia, I really like your channel
