no mater if you finish your frame please don't stop your video series .you are part of my weekly entertainment :)

Enjoyed the video. I raced for Raleigh as a USCF Cat 2 just after the 84 Olympics. Now that I’m welding I long to build my own frame. Will be putting my new Miller Multimatic 220 to work.

Please continue! I have loved the journey also. Welded my main triangle recently and wish I had practiced on these settings. Your exploration makes these clips accessible to us aspirational builders. I also use an aluminum heatsink with a mitre that I have on a threaded rod to access deep tube ends. Have you made your own BBS's as this is a good project also. can't wait for series II.

Great build I am hooked cant wait to see it finished so you can start another one.

your welds are great your fit up is great if you're having a hard time staying in your line use some extra light I have multiple lights on my welds and pulsing good it's all about timing. try pulsing .05 I use that a lot especially on aluminum

Excellent, nice heat cinc backing bar. Good idea to make one.

I was trying to find an easy way to build a bike.. found a video of yours... and finally..i watched ALL of your videos in just one day!!! EXCELLENT!!! Now I can t wait for the next one :-) Please continue building ! I was wondering how do you find the time to build,film,edit.. work,raise 3 kinds,etc... have you invented a 40hours day ? :-)

The rule of thumb is 1.5 amps per thousandths of thickness. So, you set the amperage 4x high and then 25% duty cycle. Whatever works. Here's the usual way to do it: kzfaq.info/get/bejne/n9lgdbNknr6-fKs.html

I hear a lot of people complaining about their electronic boards burning up on the everlasts. How long have you owned yours and do you like it? Thanks for the vid.

Interesting, what kind of testing have you done on these frames? From what I know about 4130, you want some of that heat input and to cool it slowly because its very heat sensitive. It would be cool to see some destructive testing using your pulse settings vs straight foot pedal controlled weld.

Is there a most common wall thickness for 4130, or a standard size for specific diameter tube

Hey, Good video, let me tell you tho, I made a market leading range of BMX bikes, we used 316L filler wire for ChroMoly.

Welds look very nice. I couldn't tell, were you using the dab or lay wire technique?

You're welds are fine but I think the pulse function prompts many people to weld to fast which limits your ability to maintain torch angle and Sri length especially on coped joints. Coped joints are also not fixed amp joints, they're essentially two lap joints and two fillets. I personally would use the pedal with 45a max, your fit up is great let the pool form and dab rather than laying the wire. The pedal will allow you ease off if its getting away from you. The stacked dime look will come from using the right sized rod and evenly timed dabs into the pool. The pulse setting is prompting you to weld faster than you're capable of and add more filler than required to stop it blowing through.

Wouldn't it be more beneficial to practice without a heat sink? You know, to replicate those welds where placing heat sinks isn't an option.

is this 1.6mm rod or 1.0mm，thanks

Good job! It helps me a lot. Thanks ;)

Nice to see you missed the track welds; you should see some of my learning experiences, then you would rate yourself an expert!! Thanks for the video

fully torqued

This is really fun to watch. Are you able to weld aluminum too?

Good info. Thanks!

Looks killer. I wish I had pulse settings 😕

maybe more zoom in next time, its going to be a very good close up welding. im very enjoy your video.

you have to thick filling rod use smaler

Do you have a foot pedal ? I'd forget pulsing and just use the pedal

What are the angle blocks you are using to hold the tubing in the vise? Where did you get them?

I do some thin wall stainless and my helmet only goes down to shade 9 and I'm thinking 6 or 7 might be better. The better you see the better you weld any thoughts?

Show the INSIDE of the pipe Please!!! Your insert helps the O2 from getting to the weld, If you didn't use it you would have to fill tube with GAS!!!!

whats the the benefit of the heat sink and the puls welding?

You a bad welder !

are you using all of the amps? foot all the way down?

You should try it without pulse

nice job man. are u happy with the everlast?

Rod 1/16?????

what is filler

how stong are these welds?

where you buy these tubes ?

Better walk a little bit faster.
