[@markzurowski3627]

These videos have become the highlight of my Saturday mornings recently. Thank you, Paul and Mitch.

[@paulbrodie]

Mark, thank you very much!

[@kevinkace]

I bounce between metric and imperial as well. I think it frustrates my father 😂

[@davidsnyder2000]

Paul & Mitch thank you for your channel and content. My wife just got monetized through KZbin. I now realize what you and Mitch go through to do your videos to help teach the public. I was so dumb. The amount of time, effort, money, editing software, equipment, etc….that you guys have invested in your channel, most folks wouldn’t understand. Thank you for all you do to try and teach the general public your craft. It’s a LOT!

[@petternorman6192]

ISO = International Standard Organization

[@ultimatemonkey]

A new P.B. video that's almost 30min long ?!. What a great start to the weekend. In my opinion, between yourself and Allen millyard, you 2 are tied for the best content on KZbin .

[@paulbrodie]

Thank you very much. I am a fan of Allen Millyard....

[@ultimatemonkey]

@paulbrodie yes I recall you referencing him in an earlier video whe. You were hand hacksawing somthing .. if only the world was smaller and we the audience could get a collaboration! With your hand fitting and brazing and his engenieering I'm sure somthing amazing would be created! I'm not sure they are really your style of bike, but his MR001/2/3 downhill frames were decades ahead of their time

[@tomthompson7400]

Great to see so many variations on something as simple as a bracket.

[@helvettefaensatan]

I know a car channel you might like. They are quite good at brackets …

[@paulbrodie]

Thank you!

[@James-gx7sk]

"Eyechrometer...7degrees!" Thanks again for the Saturday AM entertainment/lesson...you're a master craftsman Paul!

[@paulbrodie]

Glad you enjoyed it. I wonder if it really was 7 degrees!

[@Steven-rd3qn]

Hello... a nice greeting from Germany. Every new video, a great pleasure for me. Thank you very much!👍

[@paulbrodie]

Hello Germany! Appreciate your comments, and thanks for watching..

[@cest7343]

6:40 "eyecrometer:..." LOL, bought me; subscribing 😂😂😂

[@thmawhirt]

Master craftsman at work but still able to inspire those of of us with a fraction of that skill to try and build whatever your passion is better and great to see him really enjoy it.

[@paulbrodie]

Thank you very much. Appreciate your comments!

[@edgeorge785]

Only Paul would retain all of those templates. Gosh i wish i had his brain.

[@paulbrodie]

It's also called hoarding. Not sure if my brain has much to do with it...

[@ianstrefford1475]

What a work of art. It would look amazing with just a clear coat to show your skills.

[@paulbrodie]

Thank you very much, I clear coated my last frame, and that became the Romax build. So, we have to do something different for the gravel bike!

[@Jayneflakes]

Thank you for sharing your craft, it is a joy to watch such an artisan at work.

[@paulbrodie]

Thank you very much :)

[@AlexKost-tq6bj]

SO awesome!!! Beautifully filmed and so cool to see the process in detail! Thx!

[@paulbrodie]

Thank you Alex. Appreciate your comments....

[@graememorrison333]

What i get most misty-eyed over in these videos is the KEF Coda II speakers in the workshop! They were my entry-point for decent audio in the early 1980s and I always wanted to work for the company in Kent, England after I graduated. (And then I wanted to be a frame-builder for Roberts in Croydon...)

[@davidcahan]

It's great to see your hair all the way back and curly. Glad to see you seem to be feeling better!

[@Alanbataar]

As always, thank you Paul & Mitch!

[@Paddington60]

Good work you two, good to see the flame on the silver soldering, well done!

[@paulbrodie]

Thank you...

[@bigbird2451]

The serial number is my birthday! Well done Sir!

[@remek_ember]

[@paulbrodie]

You are very kind. Thanks for watching..

[@karlalton3170]

Its coming together nice Paul , glad your looking better mate 😁😁🤘🤘

[@paulbrodie]

Thank you very much :)

[@Andrew_Fernie]

As a 52yr old Brit, I also use imperial and metric together. I just use whichever is easiest for the measurement I'm taking.

[@galenkehler]

I love IS mount brakes. That was a perfect system for enthusiasts, light and adjustable. And without threads in the frame it could last forever.

[@aintnobodygottime4dat]

Relaxing Sunday viewing👍🏻

[@user-lr9wy6wb7n]

Hello Paul, since seeing the first of your videos i'm addicted. I found the channel by colleagues from the mtb news forum in Germany. It's always the biggest fun watching you creating steel-art. Your explaining the fine art of framebuilding is like school with a good teacher. I hope, you will build further new stuff. Have you ever thought about building a new MTB? In Germany and I think even in other countries, a lot of fans would welcome it...Best regards to you and Mitch

[@paulbrodie]

Thanks for liking our videos.. "Have I ever thought about building a new MTB?" Well, I did just build myself a new gravel bike that just got assembled less than an hour ago.. So Yes! I have thought about it and I did make it happen.. Hope that answers your question....

[@joell439]

This frame just screams gorgeous simplicity. Thanks Paul and Mitch. 👍👍😎👍👍

[@paulbrodie]

Thank you Joell. Appreciate your comments!

[@ralphbarker7791]

Just Awesome details.

[@matejcermak]

For painting, I'd go totally by powder coating, if that's possible to do nearby. In my small european country we have made many bikes and also all kinds of machines during after WW2 era, powder coated. Most of that stuff still holds the coating well

[@georgestewart1325]

Always enjoy the content from your channel. Love the skills.

[@yodasbff3395]

Your craftsmanship is impeccable and a pleasure to watch. Thanks for sharing 👍.

[@OldSlow]

Aboslutely love these framebuilding videos and great to see you having fun in the workshop!!

[@andyjacklin9950]

Paul you switch from metric to imperial as much as you want it's up to the rest to keep up 😂👍

[@paulbrodie]

Thanks! That made me smile! I like both systems depending on what I am measuring...

[@KoematCustom]

The video is very inspiring, thank you sir

[@framolon3708]

[@simonbirt6121]

Bicycle frames are not my thing, but I’m learning techniques that I can apply elsewhere, thank you Paul and Mitch.

[@paulbrodie]

Thanks Simon!

[@rmdownton]

Switching between metric and imperial constantly is just daily life in Canada haha

[@paulbrodie]

Haha! Yes, that is how we roll in Canada..

[@maciejzielinski4033]

Ahh, I wish you would someday try building a bikepolo bike mr. Brodie. I feel like you could apply your great skills into creating some fork integrated disc brake rotor guards and all else a bikepolo bike needs! Love your work!!!

[@paulbrodie]

Some the guys that used to work for me played a lot of bike polo, and the bikes did get pretty specialized. Thanks for liking what we do :)

[@bake162]

Another awesome video in the can, nice or lads

[@WireWeHere]

A copy of the serial number that's usually hidden from view can become helpful when trying to recover stolen repainted property. The inside of the brake caliper bracket looks like a promising location and wouldn't require as much disassembly as the one in my head tube. Shelby's AC Cobras required a map to find every serial number location.

[@paulbrodie]

Yes, every frame gets a serial number..

[@iw1669]

[@paulbrodie]

Thank you so much..

[@fastbike9845]

So nice to see you back in your shop, working your magic with metal. Just got you a coffee. BTW, I made an ISO mount 7 years ago so I could fit a disk to our tandem, but it would have been a whole lot easier watching this first rather than figuring it out via very tedious trial and error.

[@paulbrodie]

Thank you. Yes, the first time would have been very time consuming I am sure...

[@1crazypj]

ISO, literally , International Standards Organisation. I think the holes would have been 'nicer' as a teardrop or stylised heart like on your shirt?

[@paulbrodie]

Yes, there are many ways to save a few grams. Mitch and I only have much time to shoot a video, so 2 holes was the fastest way!

[@richhawrylak2004]

Always learn something. The small details and craftsmanship blow my mind (Skill & Art). The videography truly helps tell the story. Thank you - both! How do you know when to nickel silver vs tig? Is it a strength vs appearance decision?

[@paulbrodie]

Thanks for liking our videos. Sometimes the choice of Tig vs. nickel silver is just preference. Usually Tig for tacking because it is strong and fast. Nickel silver flows nicely so I can make it very smooth, so that is a consideration. The Tig torch is rather bulky, and not always easy to get into small corners, so nickel silver to the rescue! Make sense?

[@robertdewar1752]

My Chas Roberts has the caliper in the same location. Handy for maintenance. Not so handy for fenders/racks.

[@TheUncleRuckus]

Wish you were still doing frame building 101 bc I would love to attend and be able learn how to build my own bike from you. 👍👍 I'm curious if you think TiG Brazing could be used instead of traditional Brazing for frame building??

[@paulbrodie]

Sorry, I am not still teaching Framebuilding 101... I have a friend who built a frame using TIG Brazing. He is the only one I know. There must be a reason why Framebuilders have not taken to this method....

[@lunkydog]

Is your peacock okay? Haven't heard him this year.

[@lynxg4641]

Paul, continue to enjoy seeing this build and you back in the shop, but am curious how come you went with ISO instead of Post Mount and having to use an adapter since the brakes you're using are PM, as are most brakes these days? Curious to see the paint design you come up with for this one, have a feeling that it's going to be quite interesting for some reason.

[@paulbrodie]

My last bike was ISO, I liked the shape of the bracket, I had a fixture, I had done it before, and it looks like I am a creature of habit...

[@marlonterbio]

Raw looks good. It shows all the details. Hoping it will not be painted fingers crossed…

[@ShotgunAU]

Legit

[@robertochiaratti1380]

👌👌👌

[@WireWeHere]

Do you ever transfer the braking load to the chainstay or is there so little flex with the seatstay? Edit: I asked too soon.

[@hugojcardoso]

How do you know that the caliper is the right distance from the center of the axle?

[@lelandnightingale]

Always enjoy following along, Paul. I wonder why you wouldn't put the caliper between the seatstay and the chainstay. Aesthetics? Strength? When I was considering a new touring bike with discs it seemed to me preferable because it might protect the caliper a bit more and make fitting racks/fenders a little easier. That said, the round brace following the curve of the rotor is👌 Thanks for your videos.

[@paulbrodie]

Thank you. If I put the caliper between the 2 stays, I would need to kink the seat stays up quite a bit to make room for the caliper, and this really does change the "look" of the frame. I, personally, have never liked that look. I like a straight (from the side..) seat stay that blends into the dropout. Nothing to do with strength. You can call me old fashioned for still liking the ISO mount, but it works great for me and I have never had a single issue...

[@lelandnightingale]

I hadn't considered the 'kink' but 100% agree that form is nearly as important as function when it comes to bicycles. Likely the bikes I saw were using smaller rotors and can get away with not needing the kink. @@paulbrodie

[@kchitlaykok]

waiting and watching this alsome

[@stephengibbs4372]

Hi , love your work and how fine and close fitting everything is, just wondering though isn’t the curved reinforcement tube going to flex as well ? I know a straight one cant compress and its all about triangulation or maybe being curved but not that long stops movement. Looks great though and im learning heaps. Thank you.

[@paulbrodie]

Thanks for liking what we do :) If the curved reinforcement tube had a "pivot" at each end, there might be a microscopic amount of flex, but when each end is brazed to the stays, the triangular structure becomes very rigid. Flex then becomes non-existent, IMO.

[@weedmanwestvancouverbc9266]

Years ago, I got Chris at DeKerf Cycles to add disc brake tabs to a Yokota tandem mountain bike I'd gotten years earlier from a former employee at a bike store on the Sunshine Coast. The original brakes were Scott Peterson SE brakes mounted on U brake bosses and after one ride with my wife down the Smoke Bluffs trail to the climber's parking lot, needed new pads. Not very confidence inspiring when the stoker is a clydesdale. I got some 6 piston Monopro 6 Ti calipers by Hope from a guy in Whistler, and 36 hole Hope hubs from North Shore bikes on Lonsdale. Because I wanted full on 8 inch rotors, they recommended I run the 9 mm through axles which were compatible with the 110mm/135mm quick release dropouts. All this needed were some interchangeable spacers DeKerf wanted the built wheels so he could get the tabs right. The dropouts on the front wheel had a clearance issue, so he did a tiny scoop out of one of the massive front dropouts in the fork blade. He also added a diamond shaped punch plate to the top of where the boss attached. The rear needed abridge tube connecting the two stays to support the extar froce generated by the new boss.

[@KostyaChernyaev]

Hello. Nice video, nice work. Why you didn’t put caliper mount on the bottom?

[@paulbrodie]

I think you mean flat mount. I'm not fond of flat mount. Personal preference :)

[@keinschwein8467]

Awwwwww, why not go for PM and ditch the adapter? I think this would have looked much cleaner. I understand that an IS2000 mount is way easier to make and get straight, but you already went to the trouble for the fork anyway ...

[@babybopkidsrock5713]

4271 in how many years? Amazing

[@paulbrodie]

Since 1984. That's when I started building frames for Rocky Mountain.

[@babybopkidsrock5713]

@@paulbrodie Average of 109.5 frames per year. Legendary stuff.

[@weedmanwestvancouverbc9266]

@@paulbrodie A master crossbow maker showed me a weird thing: He pointed out a serial number on some old equipment that had both a 6 and a 9 in it, and how much more indistinct they were from the other digits. He said the person used one of those digit sets that DON'T include both a 6 and a 9 to save on costs. So, they wear out faster than the others.

[@123jouable]

Really enjoyed watching this build! However, I gotta say this brake mount is a bit of a poor design in my opinion. There is a reason why all the other mounts shown in the beginning have that recessed area between the holes, which is to make room for the brake piston. Here, a 180mm rotor and a really tall IS to PM adapter is used so there is no problem, but it's a silly setup. With those brakes you would be fine with a standard 140mm rotor but that mount is unable to take one that small. This one does have a cool and personal look to it though

[@willgrime]

Paul, why did you drill a hole in the seat stay before welding the bracket onto it? Cheers, Will

[@paulbrodie]

Will, the seat stays are sealed, so if I want to Tig-tack and not burn a hole, I needed to drill an air hole... Does that make sense? Thanks for watching...

[@willgrime]

@@paulbrodie Perfect sense, thanks Paul. Best wishes, Will

[@lazlo2511]

I was really looking forward to this part of the project Paul but to be honest that old school hangout disc brake has rather ruined it for me. This frame has such lovely minimal proportions and looked clean. I also think having it flush with the chain stay would have been Stella. I actually was wondering how you were going to integrate that, I envisioned some extra fabrication Marvelry (even a word?). Anyways maybe the next project we can step into the year 2023. Otherwise keep at it!

[@paulbrodie]

Sorry if I ruined it for you. I like my bike.

Question: what kind of steel do you use for such plates? (4130? 8620? 1018? Something I’ve never heard of?) Note: This is early in the vid.

[@marksun.7861]

[@MarkAnderson-ym6xx]

Off topic question: what watch are you wearing?

[@paulbrodie]

You are the 3rd viewer to ask. It's a $50 Timex, nothing fancy. I just like how it looks.

[@MarioGoatse]

What are the extra holes for? Is that to incorporate different sized rotors? So 160, 180, 200? Or something else?

[@willgrime]

Just to add lightness, I suspect+t…

[@helvettefaensatan]

What level do you have to be at to become a student of yours? What skills are prerequisites?

[@paulbrodie]

Well, I am retired so I am not taking on any students. When I was teaching Framebuilding 101 my oldest student was 75 and the youngest was 15. There were no prerequisites, but you did have to WANT to learn!

[@helvettefaensatan]

I'd just think it'd be a shame just learning to weld from you, which can be done anywhere, when one really should learn the peculiarities of bikes from you. I hope you enjoy retirement. Did you gather you experience from doing it, from trial and error, or are there written sources you could recommend? I feel there is an art that is kept dark and secret about geometry, fit, and angles. Surely, some angles must be better for different bodies - also when it comes head tubes and such.

[@slimdog72]

Just one question, is the brake mount mild steel/cold roll or 4130?

[@paulbrodie]

It's mild steel, and plenty strong!

[@gdemorest7942]

Are you gonna bring that to the bike swap tomorrow?

[@paulbrodie]
