Glad you went with the seat collar. It makes sense to go that route for that type of bike. Nice!
Indeed! I'm glad too hahah.
Pithy Bikes hey if you haven't tried a coolant mister yet I strongly suggest investing in one or making some kind of syphon system to use on your mill and possibly lathe.
Oh, by the way. Love the series. I just spent the last week or so binge watching all 50-something videos on the last build.
Wow, all 50!! Good job ;)
Great tacks and welds. Very thorough purge for sure. Awesome vids.
Thanks! It seems the experimentation has helped me improve a lot. Learning what the different settings do and trying to leave no rock unturned! :)
Cool build ! Can't wait for what's next !
Thanks for watching!
Hey Steve, don't go changin'!! Another entertaining build video! I absolutely love your post production and editing.
Hahha thanks man! too kind!
Hi there, just found your channel and it's great. I'm slowly getting outfitted to start building my first frame, your videos are awesome. Keep up the good work!
Awesome! Good luck on your journey and have fun :) Feel free to email me if you have any questions. pithybikes@gmail.com
nothing wrong with those welds! Have you ever tried manual pulsing? it's one of my favorite techniques for tubes. give it a try some time!
Yes I have tried manual, I like it a lot. The benefit of controlling the amperage and timing on the fly is awesome. I ended up with auto pulse though because the burst of amps turn on faster and allows me to move faster. But really it is a matter of preference. :)
I never tire of watching quality work!
+Wildman Tech :D
Por cierto ya los vi todos y me han sido de gran ayuda, así como los de soldadura welding tips and trips! Y demás, regards from México!!
Me alegro de los videos son útiles! ¡Espero que hagas muchas bicicletas!
I'm thinking about buying a torch soon, so I hope your torch video is out soon. I'd love to see what you've discovered.
Ah that may still be a few months out from now, sorry. I have to get the seat stays on and rear rack finished first. I'll use the torch last to braze cable guides and bosses. I might make a side video to practice with the torch..
I can't wait for the "tail end" video.
(‿ˠ‿)
Looking forward to your rear end video.
Everyone wants to see my rear end.
great video man! I really like how much you have gotten better with tig! looking forward for your next videos. thanks!
Thanks! I'm trying to do at least one practice run a week. :)
You should look into getting a jewellers oxy torch. Use them all the time at work for silver brazing parts for nuclear facilities.
erikdude666 I'm not at all worried that Eric dude "666" plays with fire in a nuclear facility. Not one bit. And neither should you.
Hahaha! Its not in a nuclear facility, gets done at work then shipped to them.
Hahaha awesome, you guys cracked me up :D
Youre welds look awsome man.
(*•̀ᴗ•́*)و ̑̑
If you drilled holes where you planned to weld another tube end, so the tube cavities were contiguous/connected, you might be able to get away with just one hose.
I drilled holes all around so its fully vented. I probably could have simply used one hose.. hm.. It would be an interesting test to see if the coverage is the same.
Hi, love your channel and quality videos. If you're thinking about gas system you could try propane instead if acetylene. I'm not sure about the US but in the UK it's easier to get hold of and 'safer'. It heats up differently but it works and is cheaper too.
I considered it but decided to go with the more standard acetylene. It's easy to get in my area, just 5 blocks away from me! I would love to try propane some day after I've had some experience with acetylene. Thanks!
awesome dude
Thanks!
Pithy Bikes I'm trying to make a no weld cargo bike any tips?
fantastic work!
(*•̀ᴗ•́*)و ̑̑
Me encantan tus videos,saludos desde México wey,,,,,!!!!
Me alegra que les gusten los videos! ¡Gracias por ver!
Lookin' tough!

You need to keep your lead angle with the stinger (15* lead angle- ideally this means advancing your lead angle with every pulse). This shapes your puddle and lets you see the joint - and where to stab the filler rod. Practice without a helmet and cold. See how far you can run the bead while maintaining the right lead angle before needing to reposition. Shaping your tungsten is important, with the same size flat on the end every time.
great man! I really like to watch your videos.
Glad you like the videos! :)
AWESOME! Best Video in a long time!
Thanks! :)
Ha ha. I got a good laugh out of the intro.
:)
haha glad! :)
reminds me of the puns in the "how it's made" series!
Great video. And the puns. Oh, the puns.
sorry about that ;)
Your welds look good. I think you are going to enjoy that oxy/acetylene torch. Please let us know how it works out for you.
I can't wait to use it. I'll do a video on the setup and how it works out. I purchased a different torch at first and didn't research what to get specifically for thin wall. I ended up returning that outfit and getting the one you saw pictured in the video.
The tip size is important, as well as the regulator settings. I will be interested to see what set-up is right for thin wall. My experience is in brazing heavy cast iron and automotive exhaust pipe.
Hi pithy, you were using Gas Mapp to weld with brass rod. Did the Mapp gas have enough force to melt the brass rod to the point of melting the materials? Because you will use Oxi Acetilenio instead of Gas mapp.
Thank you very much for your videos, with it I am gathering material to also be a framebuillding in Brazil !!!!!
MAPP outfit had enough heat to melt bronze rod (low fuming bronze), I don't know about brass because I didn't try that. I could give that a try sometime if you're curious.
0:30笑いましたwww
やったね！！！Nice weld！
Hahha I had no idea there was a kanji for "LOL"! :D
Glad to see you found a clamp! Since you haven't slotted the seat tube yet, I'm assuming you plan on hand cutting it and not using the mill, correct?
I may still slot it on the mill with a special made fixture after the whole frame is welded up. But I'm not sure yet! :) I know doing it by hand would be fast but a fixture would be interesting!
If you made the alignment table vertical, then the weight wont matter, man you could keep the heatsink in, except for the bottom bracket. Just a thought
Damn, that is such a good idea. Why didn't I do that.. Next time. Thanks!
For the allignment, why not flip the frame over and check again to get an accurate representation of how much the frame droops while measuring?
Yes! Some day I want to convert my setup over to the Jamie Swan way of alignment. I think that is the best way.
I think Jamie Swan and Paul Brodie use similar methods for alignment. Not exactly the same but similar. Paul Brodie: th-cam.com/video/V2U5uhZN5v8/w-d-xo.html
always funny :) and instructive
TY!
Great video. What type of cable routing do you use on these frames?
The welds look small, are they holding up the bike when is all done? Or the first day you go out they break!
Luis Miguel Luna Pais tig welding is a small weld it actually penetrates into the base material and fuses them. mig welding constantly pushes material onto the base material but doesn't fuse them. Tig is always going to be stronger even with a much smaller bead.
Is that a monitor support, the thing you use to hold the frame while welding?
Yes it is. It works ok but it required a lot of modification to make it work. Most folks simply get a bicycle mechanics stand arm and those work just fine. But I didn't have one and happened to have an extra monitor arm.
Which types of welding is this?
Can you elaborate more.?Which is that rod of?
Kindly brief about welding plz
+jay Gajjar check out my channel. I've got a link in the desc. I documented my first build and all that stuff is covered :)
hi iam from india
are these aluminum tubes?
is this strong enough to make motorcycle frame?
please advise
They are 4130 chromoly tubes (steel tubes). The wall thickness on the tubes is not suitable for a motorcycle frame. These are roughly 1mm thick wall, so you want something thicker. I never made a motorcycle so I don't know how thick it should be.
How critical is the quality/accuracy of joint mitres when TIG welding?
Bradley Comis fit up is key in tig welding.
What material is that you're using? I'm guessing titanium?
It's 4130 Chromoly Steel
Do you not sharpen your tungsten back up? no need to keep swapping them out.
Yes, I keep a bunch pre-sharpened and ready to go. :)
Hey man where do u get all ur tubes I would like to build a bmx frame...thank u
This is THE list. :)

Pithy Bikes thank you
where did u get that frame jig from if I may ask ?
I built it!
th-cam.com/play/PLaz6WjKNr9tWLGoZ0VHaOzHWSWw_ybLQg.html
wow, awesome, didnt see it cuz i am new to your channel, but thats very inspiring :)how many hours did u need building your first bike with that jig ?
THE PUNNNNNNNS
Sorry about that ;)
is that the ove glove?
+joshua meyers I'm not sure what it's called. But I got it off amazon as a single glove. I think it is..
great job! just a suggestion, your welds show some "craters" that are typical of a too much quick down-slope current setting, you should make some try to find the best setting. and a general warning for all welders: be careful what you use to clean up the parts before welding, read this story www.brewracingframes.com/safety-alert-brake-cleaner--phosgene-gas.html
Thanks for the tip! Yes I need to work on those crates :) I'll work on that down slope.
do mountain bikes follow the same pattern of normal bikes.... That is cheap bikes are steel frames, intermediate bikes are typically aluminium, and expensive bikes are carbon fiber. Are there certain materials that mountain bikes can/can't be made of?
Basically all different types of bikes are still made with any of these more common materials: Chromoly Steel, Aluminum, Titanium, Carbon. They are all considered quality material. Only reason why someone would choose one over another is rider preference. A mountain bike can be made of any of these materials.
Okay thank you, I'm glad I found your channel on bike building, great videos.
Hi Steve, setting machine for tack welding ?
I change depending on wall thickness. For these tacks I was at 100 amps and no pulse.
My amperage for 0,5 mm is 70 A (no pulse)
LOL @ 3:33 hahahahahahaha. #SaltBae
:D
I was waiting for the "Bow chicka wow wow"
:D

bad joke
I agree. :)
i like your back purge manifold you make it?
