Great video. I love the explanations and the detail. Building a bike frame is a dream of mine, but for now, so great to watch such a well done and informative video. Definitely going to go back and look at some of your other video.
Started watching a few weeks ago and soon caught up. Now I am subscribed and excitedly awaiting each new episode. You are doing a fine job Sir, keep it up.
Nice work mate. It's encouraging that you are finding the time to commit to this passionate pursuit as a family man. You are well on the way to becoming a master steelsmith, keep it up!
Hey dude, really nice videos you're putting together! I appreciate you putting in the time and effort to document this build; it's going to be super helpful for my up-coming MTB build.
Really enjoying your channel, I respect the fact that you are learning and don't try to hide your errors. Also it's really interesting to see how other people work through problems. That said please don't start your mill with the bit partially in the work piece, your just asking for trouble. Also an good formula for your milling and lathe work is 4cs/d. where cs is the cutting speed and d is the diameter of the thing spinning. So to drill an 1/4" hole in aluminum cs is around 300 it would be (4*300)/(1/4) = 4800 rpm.
I am always been ur fan . Ur video provides information and also calmness from ur voice . And dude we are hungry for more stuff . Hope to see some more gud stuff from u soon . TC
I have been watching your U tubes on bike building from the start. As a retired tool and die maker/machinist instructor, do some research on cutting speeds. Using high speed cutting tools you can burn out your cutters very quickly running too fast as you did in this video. The reason you are getting lucky is that you are cutting thin tube and only a few pieces. When milling you are climb milling that can grab the cutter into the material and break the tool as well as damaging the work. I am very impressed with your engineering ability using common sense. I would like to have a shop in my garage as you have. If you have any questions, please post, I would love to help you if possible. John Z.
+John Z Hi John, Thanks for the tips. I've not been paying enough attention to speed and feed rates and I really need to start. The video may have been a little misleading because for some shots I sped the video to 4x speed. But regardless, I know my rpm is too high and burning out the tool. Thanks for watching and giving me something to think about :) I'll take you up on the offer if my future test put me in a pickle.
Really liking your videos dude... I just built my 1st scratch build frame and have realized the importance of having a good jig. i am in process of designing and building one. i want to make lowered stretched cruiser style frames
Congrats on the first build! Yes a good jig makes all the difference. But a complete jig is not always necessary. I've seen folks build a frame in sections. For example, they'll have a fixture just for the rear end to weld CS to BB. But I hear you, a full jig really can speed up the process.
Only the second video of yours I've seen, and I have to say I love watching you. Both videos are well made and the content is great. I like that it is obvious that you are an amateur but you are pretty meticulous and produce quality work. I also like that you use an Everlast machine. I have their 140 MIG machine and I have to say it makes me a worse welder. It does everything so well that I have no excuses but user error when welds are not perfect. There is no challenge to using it.
+Brian Choitz Thanks for watching! I've always wanted to try MIG. And yea Everlast, I'm so happy with this machine. Once of the best shop purchases I've made. Thanks for watching.
I suck at bmx. So I don't think I'd do a street bmx justice since a good street bike construction requires someone who can actually ride street! You could probably take what I show in these videos and build yourself a better street bike!
Everything functions properly czcams.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Nothing was damaged in the box aside from a decal on the fork. The decal was missing a piece of a corner but I ended up peeling them off anyways. Assembly is easy BUT make sure you tune up the derailleurs. Both the front and rear need adjusting. I'd advise going to a bike shop but I opted out and put in 10+ hours with the help of CZcams. Ended up fraying a shifter cable but all in all I learned from the experience. The Brakes work well but the front caliper needs adjusting or at least mine did because the rotor was rubbing against the pads. Make sure you swap out the seat, grips, and pedals. For the short run you'll be fine though. I've read that this bike isn't built yet for hard trails but I just need it for the city. PA has some of the worst roads and being in a mountain this was a great choice. Worth the investment!
Well done Steve. Looks great. I would caution you on the speed that you're running those cutters. I was sure that they were going to grab and fold the tube in on itself. It worked this time but.... Looking forward to seeing your alignment checking solution.
+Alistair Spence Hi Alistair! Thanks for the words of caution. I frankly don't know what rpm to run at. Back when I first started notching, I was running at a low rpm. But I got in the habit of over compensating out of fear that the teeth would grab and fold the tube. What rpm are you running at? Maybe I need to run it at around 400 rpm and use plenty of lubricant. And feed slowly. Cheers.
Theory says that cutting speed for steel bicycle tubing is around 100 SFPM (surface feet per minute). For an 1 1/8" hole saw, that means you're looking at 320 rpm. In practice, that number works well on a rigid setup on a "real" mill (ie. Bridgeport knee mill type), but on smaller bench type machines, I do think that running the hole saw at a higher speed does help give a better cut. I kick it up to 400 - 450 RPM and feed very slowly on my Grizzly G0704. Also, getting the hole saw as true as possible will help a lot. When you don't have a the mass and rigidity of a larger mill even a single tooth can snag and ruin things. Face the back of the saw in the lathe and check the runout. If it's still off, true it up using a carbide lathe bit, or note the high spots and dress them down with something like a band file.
+Alistair Spence Thanks Alistair, yes i actually forgot to face the hole saw. When I was editing the video I noticed how much it was off true. I got so lucky with that cut.. 450 rpm sound good. I kind of settled with the way I was doing things but I need to re-evaluate my methods :)
unlike the others you are milling with this tiny milling machine instead of bridgeport type milling, is that machine totally sufficient for frame builders? can you recommend it for all frame builders?
Was eager to see how you would notch your seat stays as it is certainly the most difficult part. Was wondering if you would rely on something less professional like using notching software. To remove the overlap, you could have used your dremel grinder instead of your band saw. Doesn't this fine frame jig garanties alignment of the frame?
Pithy Bikes - great series - thank you! I'm building a recumbent and have gotten many useful ideas that easily translate. I'm sorry if you've already identified it, but would you say which model of the digital angle gauge you are using?
+rapanui222 It's a Wixey WR300 - I got it for $60. But now there appears to be one called WR300 type2 which is half the price and looks the same.. heh.
Friend, excuse how to write , I am using a translator onLine. I live in Brazil and I am wanting to build bicycle frames , I watched all his videos and I am thrilled!!! You use a program to calculate the length of the tubes and angles to build the frames I appreciate your attention Thanks!!!!

+Zev Hoover Just watched it. OMG you're totally right! I need to change it. Even the dot thing is similar.. Thanks for the tip. I hate when this sort of thing happens so I'll be changing it for sure!
great works
That frame looks GORGEOUS!
+Superdude Superdude thanks!
Glad I could help! Build is turning out great!

Amazing job and explanation thanks a lot
Yo are the man! My eyes enjoyed this so much.
damn. That's a lot of work. Thanks for sharing!
My pleasure! :)

+Cooper James Thanks for the kind and encouraging words!
Something incredibly soothing watching these videos, although I'm sure the process makes you nervous at times! Great job.
Sometimes I almost fall asleep whole editing. But I think that's because I'm exhausted ;)
Agree - watching someone build stuff is a nice way to end the day.
Hey dude, really nice videos you're putting together! I appreciate you putting in the time and effort to document this build; it's going to be super helpful for my up-coming MTB build.
Rad, I want to build one of those in the coming year! Good luck on the build!
Impressive video and impressive work!! This is art!!
I try to tell that to my wife but she doesn't believe me.
Great job I like very much!
thanks for watching!!
Your may hero mate

+Demoni696 Awesome tips man! Thanks so much, I appreciate it. I need to get an rpm readout for the mill.
You're Awesome.
watching your videos, reminds me of working out of my shipping container. i would like to have a small shop someday. i really enjoy your videos.
Ha! It looks big in the video compared to being there in person :)

господа, спасибо за просмотр .
top notch video as always bro - pun intended btw ;)
+BenTheBikerBoy LOL
I think you should make a frame with super boost plus spacing, flat mount brakes, and 12 mm thru axles.
It's a good idea to frame a good bike. We know udell from Indonesia. I subcribe your channel recordings Please brother make a BMX street

How did you mark exactly where to notch ? From the drawomgs top view ?
Great video as usual! How come you own so many machines? I wish I had half of them! haha keep it up, almost there!
More machines more fun!
Hallo sir, very great video iam very enjoying this video, and sir would you like to sharing tips to make a bootom beacket shell and head tube?

Hey, what can I say, what you did worked!
Good idea to keep an eye on feeds and speeds though. Give yourself the best chance of success.

Probably no answer as not answered other questions but here goes. What size tube do you use for your frames and what size hole saw do you use to notch them?
Oh my god I forgot, its been too long. I'll find out and then post it somewhere to help ya'll out.
This is hand made slipway?
where can i buy your jig frame?
They're not dropouts; they're fork ends.
Why do I feel like if I ran my hole saw that fast my entire everything would blow up.
Hi.what materials you are using?thanks.💪💪💪💪
Cara sou do Brazil vc poderia me dá o seu projeto para mim fazer uma aqui no Brasil
What material are those pipes? and where do you buy them?
They are 4130 chromoly tubes. I got these specific one's from Henry James - www.henryjames.com/

12:01 backsound music ? I wanna know this song
you know if you set your work on that table your grinder works ALOT better
+Timothy Jones I'll try that! Don't know why I never tied that before. I got so used to doing it my old way...
your logo is almost exactly the same as philip bloom's.
+Zev Hoover Just watched it. OMG you're totally right! I need to change it. Even the dot thing is similar.. Thanks for the tip. I hate when this sort of thing happens so I'll be changing it for sure!
Pithy Bikes no probs. love the project btw you are the clickspring of bicycles. do you plan on making more than one?
Pithy Bikes aslo if you want help with the logo I have some experience with it and would love to help
not about bike, but, is that a Starfleet tatoo on your arm ?
It's not lol, but lots of folks think it is! I started that back in my teens but never finished it.
oups sorry :) !!
Hola me gustaría ke me regalarán una bicicleta de esas fixe aria lo ke se verdad (enserio) ok gracias 😁😁😊
Would happen to be an engineer?
+Aidan Stewart I'm not. But I am a visual artist. Hence the lack of math in my videos ;)
Can you make me a frame please. Im from Philippines , my birthday is this coming March please...
Can you give me a old one? Because i want a fixed gear but im only 15 years old and me and my parents dont have money to buy a bike
Hello I'm Michael Jabiguero Dapdap
From the Philippines can you give me a frame of mtb pls
