Looks OK to me! And it's WAY nicer than my gnarly oxy-acetylene welds. Keep it up!

Got it all built up and I couldn’t be happier with how it turned out. I ended up putting CushCore’s in to keep the tires from burping air on the dually rims, but besides that one little thing I am very pleased with it.

Thank you
That’s it, like anything time and practice is the only way to get better. I’ve been challenging myself under the hood and at the machines I’ve acquired.
It’s crazy to me when I look back at where I started a little over a year ago. I couldn’t have gotten to this point without some of the feedback I received on this site.

Once you have the basics down, time at the bench is the key. Well done.

Just goes to show what time at the bench can do. Well done.

They just keep getting easier and easier. I dont use time as a metric, but I do keep track. This frame start to finish was a hair under 9 hours start to finishing including making the yoke, and working out some details with the dropouts (chainstay pad is .740 and chainstay is .750)
The main construction is becoming less of a focal point and that’s allowing me to focus on the smaller details.
Alignment early on was a struggle for me and while it’s always at the forefront of my mind, I don't dread bolting a welded frame to the bb post anymore. Ive gotten to a point where I trust my construction techniques, I’ve developed my process, and I’ve honed in my welding to the point the the results are as expected and fall within the range of acceptable outcomes.
I also made a fork. It turned out ok, I learned a lot and the next will be better.

Re: Seeking some constructive criticism
Nick,
Unlike steel, Titanium is very subject to failure due to undercut, or starving the joint. Specifically in acute angles, where your torch is pulling more material from the two surfaces, it is vitally important to feed the puddle to ensure a smooth fillet between the two. This can be accomplished by using a larger filler wire or by multiple passes.
Pictures 6 and 7 above, show areas that need to be fed more material to reduce the probability of focal stress failure.
Gas coverage is looking great...I hope you continue to enjoy the journey!

Rody,
Thanks for the tip and reminder. I intend to lay filler heavily into those areas once I tack and begin welding the rest of the frame. I have developed a sequence that has me start at the back of the thin areas on the bb and work forward towards the “ears” on the downtube/seattube/bb junction. I find this helps me establish my puddle and lessens the chance of blowing out one of those ears. I’m hoping this translates over to titanium well.
Thanks again for your tips and guidance
