Hi everyone, sorry about the audio sync issue! I edited this from Mongolia and the audio was fine when I rendered it out.
Did you listen it on Bluetooth speaker/headphones? Becose some of them can have huge delay on audio🤔
Must have been the delay due to the sound travelling all the way from Mongolia?!
It's ok Mitch we'll let you off this time
@@LestaAZL Yeah, I think that was the issue. I didn't bring my wired headphones with me. My first and last time using bluetooth headphones to edit.
lol, I was about to reboot after watching the video.. thanks for pinning this comment!😆
" That looks like a pretty good fit ! "
I would say, that fit is more then perfect ! 😉
Thanks Willy :)
Butt detector is the coolest shop tool I’ve ever heard of.
Yes, and it works like a charm...
@paulbrodie 👍 That's our fussy frame builder we know & love!!
Thanks Paul and Mitch !
pats on the back are a good currency when its a good fit
Thank you Mr. Brodie
Always a pleasure when a video pops up.
Thank you :)
I love the excitement when you nail the seat tube alignment. Not that anyone of us would expect anything different
Thank you. I don't always get it as good as that, but I have had a lot of practice and experience.
Love this channel shows the warts and all.
No sense hiding the stuff that doesn't go right. That's not the real world...
As always, thank you Paul and Mitch for another video. I've done brake caliper mounting on my various motorcycles -- bigger disks than stock, different calipers, and alternative link front ends from scratch. I've measured diligently. I've drawn plans. I've milled carefully. At the end of the day, the most efficient way for me is to make up a 4 spools for the mounting bolts, and just use a bunch of ugly scrap and globby MIG welds to establish the relationship between the holes. This gives me a real "part" which I can reproduce in nice material.
Thanks Paul! Now I want a gravel!
No doubt about it, Paul you are a star 👍
You are an artist!
Thank you very much :)
Thanks Paul for teaching us these techniques (and Mitch for filming, editing, etc!)
Thank you :)
15:45🌟🌟🌟
Never seen a Brodie bike before, until I lived in Victoria BC. Marty's Mountain Cycle in Esquimalt have many.
Yes, Marty used to order a lot of our bikes :)
Haven't been on in a while, glad to see you are still at it! You guys are awesome
Good morning mr. Brodie, Mitch,
Loved this episode. Cheers!
Shame I never hauled my butt over to Canada for frame building 101.
Thank you. Yes, Framebuilding 101 is no more...
Good afternoon from Lincolnshire UK
Good afternoon. Thanks for watching!
Super interesting 😀👍🏻
thank you!
Thank you, Mr. Brodie! Thank you, Mitch!
Thank you too :)
Loving it!!!!
Thanks!!
Always legit.🤩
Thank you.
Liked the video! A couple of remarks and questions about the brake mount.
1. Flat Mount can take up to 180 mm disc rotors. But of course originally it was meant to work with 140 mm and 160 mm road discs.
2. Why go after the Post Mount interface instead of doing International Standard, especially when making one-off frame/fork? An IS mount could be just a plate with two unthreaded holes, to which an IS-PM (or even IS-FM) adapter is then attached.
there`s no stopping the dynamic duo,great video thankyou mitch
and paul, look forward to seeing how you sidestep this slight
caliper mount snag Mr Brodie, not many would have the skill
and patience you boys have, chapau 😊👍
Thank you... Yes, I did figure out the caliper mount for next episode :)
In these days of CNC it's fascinating to see how a real engineering plans his construction, tries to foresee all the problems and finally works out how best to solve them. Superb as ever👍👍
Thanks so much! :)
Imagine the bollocking you would have got off the foreman when you first started, telling him you hit a parallel with a milling cutter 😂
Yes, I do sometimes make mistakes...
Mr Brodie,,i'm very excited for the straight and convictions you expel,,so pleased to see a light back in your eye,, your encouraging on many levels,,---A,,Keep fighting the gud fight kind sir..-mitch yer doing great things my friend..Cheers
Thank you very much!
Thanks Paul & Mitch, another great learning experience. Glad to see you're doing well!
Thank you very much :)
I feel like I've been waiting years for this video. Thank you! Keep up the amazing work. ❤🎉
Excellent! Two steps forward and one step back, but always progressing and getting better. I learn so much from each of your videos!! Thanks so much!!
Very true. Thanks for watching!
what a beauty!! We enjoy the success but also when it does not fit perfect so we have another video 🤣 thanks paul and mitch!!
Always more videos... thanks for watching! :)
I learned something too. Thanks Paul and Mitch. 👍😎👍
Glad to hear it!
For the average human that is why PMW exists I guess? Thanks for bringing us along and glad you are looking and sounding good!
I'm loving this frame build. Thank so much for bringing us along.
You are so welcome! Thanks Mark..
An absolute pleasure as always Paul.
Thank you very much!
I'm excited to see this bike all finished and out on a ride. Get it muddy!
That's the plan!
Paul if you draw your component shapes to scale the fitment issues will be minimized. I like the way you work thru the fitment processes with such patience. The caliper brace needing manipulation is always specific to the caliper being used.
❤nice 🎉 love it this is probably not the first one..ha ha
Hey Paul, it's very valuable to see how you problem solve in real time. I've dabbled in framebuilding enough to know that it doesn't always go as smoothly as you hope it will.
Yes, I was really "winging it" making that brake mount. And I did make another one after all. Thanks for watching :)
🔥🔥🔥🔥🔥👍🏻
The worm bender is spectacular bit of kit.
Ok now how does he do the second bit... You pull out a second piece that fits into the first... Amaz ing... I understand how it works.... I couldn't have come up with that... Genius thought process.
It's been a while since I visited and your stuff just keeps on keeping on being great.
Thanks to you both.
By the way, the audio sounded/looked fine down here in Thailand.
Maybe the sync gets a bit wonky crossing the Pacific.🤣
Tack sequence video please!
I don't think there's enough content for a whole video, but what are you not understanding? Thanks for watching.
Big thanks for sharing your garage time! I appreciate all the tips you share and how you even share your first attempt, literally the best channel on CZcams!
Great work, guys. Thanks.
Thanks for watching!
Thank you, Paul. Watching 👀 you at work is so relaxing, and I learn so much at the same time. I'm more in a motorcycle, but it is almost the same except for an engine, of course 😀. Have a good day!!!
Hi Paul
I had the same brake rotor clearance issue with my bike. Hope makes a V1 and V2 floating rotor. The V1 rotor to aluminum spider attachment is closer to the centre and gives more clearance to the caliper mount. Disco Brakes also sells a nice floating rotor that doesn't have this clearance issue.
Chris
Hi Chris, the clearance issue was my fixture, so I ended up not using it and mounting the caliper by clamping it to the rotor. It's ok for a one-off, not for production..
Excellent video! Thanks Paul and Mitch. It's great to see the progress on this build.
Hi to Mighty Mitch ,,, Your looking great these days ,, and the bikes coming on well too.
Hope so!
Heh heh, you said "butt detector".
Thanks again for the lessons.
Yes, I did say that.
My butt is on my behind and I still haven’t figured out where I’m going. 😂
You will figure it out !!
Enjoyed the video. It's always a pleasure to watch a talented craftsman. Thanks for sharing 👍.
Thanks for watching!
It’s like watching God reveal all his secrets!
Uh oh! Mitch is not working that hard actually... He got the audio sync way off this time 😂
I thought I was going crazy! Oh well, still enjoyed the video.
@@nefariousyawn Haha! I always enjoy watching Paul work. He's a Zen Master
The out of sync really didn't bother me except for the scenes where Paul is filing the miters. Oh well :)
@@GreggMax Yup! That was the worst part of it for me too. It's like watching someone play the cello with the sync timing way off. To be clear, I love these guys, I just found it funny because right at the beginning of the video Paul made it a point to assure us that Mitch is working really hard 🤣
I didn't even notice 😂 keep up the good work Mitch🎉
Great work, always a pleasure to watch your videos
Thank you! Cheers!
Enjoying this build, looks great Paul! 👍👍
16:22 Flat mount can be used for all rotor sizes. I designed my road fork with 180/160 so I could run the larger rotors.
Can we assume that the brake mount plate is 4130? Guess my question is it acceptable to use mild steel any where on a bike frame? Stoked to have more bike content.
The frame is coming on great. Is that a Hope Pro hub I spot there in your wheel? That's going to be a fine build coupled with those Hope brakes!
Yes, I like that Hope stuff a lot!
If it's perfect, it has no character.
Very true, thanks for watching..
Love the Excelsior artwork on the wall. Maybe offer up a version on your web shop?
How do we get where we are without mistakes 😎❤️
Exactly. So true!!
No matter what the set backs may be you will get it figured out. That is way "custom" is pronounced "cussed em"
Thanks. Haven't heard that one before...
Thanks so much for all this great content, guys! At 9:16 we see the 2nd miter happening with the tube already clamped in place. Paul, how do you keep the two miters in phase with each other, rotationally, along the tube's axis? I've been using pairs of paragon clamping tube blocks on either end of the tube along with a flat reference surface. A little klunky & also difficult to screw up. I'm interested to know your method, Paul, & thanks again!
To mitre the second end, I hold the tube lightly in the V-blocks. This is for a top tube.. I mitre for the head tube first, then hold the seat tube end in the mill vise. I put a head tube into the first mitre and eyeball it to be vertical. That is good enough for me. Make sense?
Got it.. just use the ol' eye-crometer. Thanks again!
Worth looking at the 1996 Shimano frame requirements PDF that's doing the rounds. Has the post mount specification in it including clearance.
I really don't know how I ended up with that sketchy fixture... I did figure it out and now it is all good :)
4:45 and 10:10 You have a very rare file, it produces a filing sound that is out-of-sync with the filing action!
You are correct. The audio was out of sync. Sorry.
@@paulbrodie Hey, I was only pulling your leg, it's the content that is important and your content is great!
“It’s okay… I have a file.” 😂😂😂
New brodie quote for merch
Thanks for sharing the process. Is it just me or the sound is actually slightly off video. I'm watching in 1440 HD.
It's not you, the audio is slightly off, sorry. We will do better in future!
Dear mr. Brodie, did you ever by mistake use one of your incense sticks as filler rod? It looks like that could happen easily!
It could happen, but it has not.. You will have to take my word for that :)
👍👍😁😁,,
Is there an interesting story behind the rotary phone?
A friend gave it to me because he didn't want it anymore. He worked for the phone company for 35 years. No real "story"...
Why did you not use an ISO mount here, with an adapter, as you did for the rear brake mount ?
How do they get the distance between the butts to be a smaller diameter? Can’t quite grasp how those tubes would be manufactured. Welded?
It's the thickness of the tube that changes with the same outer diameter with internally butted tubes which aren't welded but done with a mandrill press pushing the tube through a die (ex: czcams.com/video/QKAg1yMZIpY/video.html). Some builders will also externally but the tubes with an CNC (I believe Baum and No.22 do this, ex: czcams.com/video/uZCFSzQdFdM/video.html), in this case the outer diameter does change.
@@thomaslowry7813 thanks for clarifying. For whatever reason I was thinking the inner diameter was starting at 80 thou and then changing to 50thou and back up to 80. Makes a lot more sense to have the outer diameter different, but would think you could just measure with a calliper on the outside?
@@markmywords5126
that is correct tho. The wall thickness is thinner in the center than close to the ends.
the outer diameter is not different, thats why it has to be measured on the inside. There are however outside butted tubes where that is the case.
Mark, you are correct..
You're welcome. However, it is 0.8mm and 0.5mm, nothing to do with thou... 90% of butting is on the inside of a tube.
its aways the third one that is correct ,?
Second or third. Mostly the second :)
Great image Mitch of Paul brazing the top tube , one to frame I reckon.
Well thank you very much. Mitch has talent :)
How could someone go about acquiring one of these gravel bike frames? :)
Butt Detector!!!!
Yes Sir !!!
audio lag for anyone else?
Keep that butt detector outta Wal-Mart.
👍🍻
Audio was desynced through the whole video for me.
Yes, we had a small issue, sorry..
Wow, audio is way out of sync
what's the butt?
Some tubes have a butt, some do not..
Tell Mitch to work harder. Your audio is out of sync.
Yes, we know. Sorry.
WHAT'S WITH THE DUBBED FILE SOUND - NO BUENO~~~~!!!!!!!! MIIIIIITTTTTTCCCCCHHHHHHHH!!!!!!!!
What hole saw are you using to miter the tubes? Lenox are nice and sharp but the tooth offset makes them suck.
excellent, outstanding, interesting video thanks. on a different tack what's that old fashioned wall mounted telephone, with the old rotating dial? please talk and show it, make it part of the next vid, I and many other people I'm sure would find it interesting
Cool, thanks. The phone is from the 50's; a friend gave it to me. Constructed from Bakelite, it is surprisingly heavy.
@@paulbrodie put it in the next vid
flat mount is max 160mm rear and 180mm front, but yeah, PM is a way better system
I have never owned a bike with flat mount. My understanding is that they were primarily designed for road bikes...
Yeah, I have it on a gravel bike. In theory FM is meant to be more aero. Mechanically, in my opinion, it doesn't make much sense.
In general there are three major kinds of gravel bikes:
- Touring bikes, now they call them "adventure bikes"
- like MTBs from the 90s with drop bars: for under-biking MTB or just riding around not giving too many f*cks
- Endurance road bikes that you can use with wider tires for all kinds of roads. Geometry is similar to the 90s MTBs but lower BB, longer reach and shorter stack, light and relatively aero.
For me it's the third type. I live in Australia and here there are normal roads with tarmac and unsealed or gravel roads. But the concept is the same, road cycling. If I need wider tires, suspension, dropper seatpost etc. I get my MTB. For touring trips I also get the gravel bike, but I take it easier... Make it last longer and sleep in hotels ... if there's any
I love your channel! I even watch all the motorcycle stuff.
One advantage - ISO/post mount afford less set-up effort with the brakes. Sklar is producing gravel bikes with ISO forks. The partner selling is The Pros Closet with The Radavist. There is an anti-flat mount vibe emerging from that crowd. Justified or not, I get it. Flat mount has gravitated past use on x-cross and gravel to even some cross country race models (Canyon and Mondraker).
Keep up the good work - I agree with your choices for this build.
