- Hobby framebuilder. Video series of me building a new bike frame in my garage. This will be the 8th frame I've built, but my first CZcams video series. The new frame will be built up as a trail bike with 27.5 wheels and a 150mm fork.

I'm a big fan of this playlist from Paul where he builds a Brodie Romax:
• Romax Build
Check out this playlist from BikeFarmer @bkefrmr where he builds a lugged steel adventure/touring frame:

👍👍Great video series!
Thanks!!
Hey - Thanks for dropping by my channel and leaving a comment! I just subscribed and look forward to following along on your bike frame build journey. This will be really helpful to me and I'm sure lots of other aspiring frame builders.
I’ll be doing a lugged bike on my channel in the next couple months too. Looking forward to seeing some fillets here while I move along!
@@bkefrmr That's going to be fantastic! I subscribed to your channel a while back too. "Your Bike Sucks", and the "Bicycle Mechanics are Assholes," videos were gold!
Thanks Hey! @@Henrywildeberry
Thanks @Henrywildeberry Do you have a plan for your build?
@@ThriftyFramebuilder I've designed an idea in BikeCad. It's a road bike with slightly relaxed geo.
The miter finisher idea is really great! Love it.
Thank you!
Excellent! More framebuilding on youtube is never a bad thing!
Thanks, I agree!
Looking forward to this. Thanks!
Thanks!
First like!
Thanks man!
Second like!
Thanks!!!
Ive been debating buidling a frame that resembles my Jamis Renegade or simply ordereing a set of seat and chain stays and just elongating and widening the rear traingle to accept some 700x55/29x2.2 tires, by the way I think I just binge watched all of these episodes about 3 times already lol
THANKS!! I’ve definitely been tempted to rebuild the rear end for more clearance on a production bike. That might actually be my next project after this frame is done.
Yep I am a big fan of Pauls vids.
They are really well done, both in the production and the content. Super cool to be able to see into the world of a professional framebuilder.
Wonderful video and explanations. I like your jig, any plans for that anywhere online? As someone interested in building my own frames this will be an invaluable series, thanks so much for sharing your story. Subscribed and will eagerly follow along.
No jig plans online that I know of, I just looked at pics of other jigs and kind of made it up as I went. I’ll eventually do a “tool” video with more info on it. Maybe sooner than later… it’s supposed to be COLD this weekend. My plan at this point is a video every other week. Thanks for subscribing!
@@ThriftyFramebuilder thanks for the reply. I keep looking at more and more jigs and will use the 80-20 profiles when I build one. I am unsure whether to go with a fixed ht jig like yours, or one with adjustable angles, which will definitely need more parts to function.
A tool video would be cool to see.
Thanks again for sharing what you are doing :)
These videos are amazing - so great for people with modest tool setups. So thank you for that! I'm starting tube prep for my first frame tomorrow :) Is there any chance you could post the note on your phone with all the steps? I would really appreciate that! Cheers
Thanks!! Here you go... lots of stuff specific to my tools and process, but I hope it helps. Good luck with the first frame, and have fun with all the problem solving and trial & error!

@@ThriftyFramebuilder Consider making this its own comment, and pinning it to the top of the Comments Section, so everyone sees it. Thanks for creating this helpful and inspiring content. Hope all is well,
@@SlimOneable Done! Thanks, great idea. I'm still a bit of a CZcams newb.
@@ThriftyFramebuilder You’re doing a great job refining production values, as you’ve refined your frame building process. Well done.
Do I spy the River Bottoms in those pics?
👍
👍👍😎👍👍

Really looking forward to this. Apart from the acetylene class, did you have any prior metal working experience? Perhaps as the series progresses you can discuss what tools you used on your first frame, and what tools you added along the way (and why).
Thanks! No real prior metalworking experience, other than shop class in junior high 30+ years ago. I was planning on just such a video! Might happen sooner than later if it stays cold in my garage.
Almost all of your frames have interesting connection of chain stays to the BB is that called yoke? I am looking forward to see how you do them!
Thanks! Yeah, it’s called a chainstay yoke. I’ve used a few different types. All the frames except for my current fat bike have a chainstay yoke.
Where did you start to learn?
Basically I learned from the internet and a local Intro to Welding class. Check out my “Everything You Need for a DIY Bike Frame” video for more about how I got started.
