ALSO, nice looking frame, kudos!

AHHH! I thought that might be something like that. the sharp eyed, picture analysts would have noticed the disk brake mounts, but not I! brilliant solution to a real world physics problem. although i have a disk brake, QR setup on my cross bike, and i have never had the axle budge even a millimeter. I think this is akin to the lawyer lips solution to ineptitude in QR use!

I’m not sure what I hate more, lawyer lips or thru axles. With the disc brake mounted on the back of the left fork blade, one or the other is necessary. I’m getting ready to build a new fork for my gravel bike with the disc mount on the front of the right blade. That should cause the torque from braking to push the axle into the dropout. I’m not sure if there are any unintended consequences other than, “it doesn’t look right”. I’ll soon find out.

Just thinking as the bike business lifer that I am, through axles must be the dream fulfillment of every company counsel in the industry--a trend that has the potential to kill off standard qr's forever!

The down tube has been "squeezed"/pressed on hard by something at some point as well as it is not quite round for 4 or 5 inches of its length. I've had this frame kicking around for years, because it seems "too nice" to cut up, but it's pretty beat up all in all. The seat tube is the only tube that isn't dented and or bent. If somebody really wants to make a rider out of it I'd consider shipping it to them for the cost of shipping, but I'm %95 sure that such a transaction would result in the frame sitting around their shop for a few years doing nothing just as it has sat around my shop for a few years doing nothing. It's time for something to happen with this frame...

That one's a tiny, fast but comfortable road bike. I made a custom zero reach quill stem for it and despite the small size it is really fun to ride!

Thanks! I sent it out as a frameset for a 6'4" rider:

Thanks, and great ingenuity on your tall bike! Here's two slight variations of the build:

The fork is too nice to call it garbage though, it will undeniably add a touch of class to the bike!

A few C&V members may be too modest to toot their horns in this thread. Forum member John Clay @Jmclay has built a few really sweet bikes, one of them combining the cush of Rat Trap Pass tires with an internal slip-ring for dynamo light wiring, oh, and it rinkos!

That was my point in all of this,many here wield a torch with great skill and while they may not do whole frames I'm pretty sure they could.

A friend bought a bike with discs and through axles for their son, a helpful uncle mangled one of them. not that cheap to replace! All special order.
We are on the verge of the return of the last last century (1900) where many cycles had unique mechanical solutions specific to the brand.

Yeah, 80mm drop with 700x42 tires is like 61mm drop with 700x23 tires. Pretty conservative, actually.

Here's a good article on the subject.

Started building in 1996-7; this was #12 out of 23 so far. I have done a bunch of repairs--more tube replacements than frame builds and about 80 dropout replacements.

Most here hold you in high regard, many of us can wrangle just about anything bike related. Swap parts, do a ground up parts build with great skill, modify, fabricate and repair many, many things, threads, cable guides, dropouts and much else. Paint and touchup, rust mitigation, cleaning, detailing, polishing to name a few.
But it is a whole other level to build your own frame, the difference between a line in the sand and the Grand Canyon as it were.

I’ve been blessed to work with Anthony Hobbs & Flying Machine Bike Co. on three projects (2 mild mods & 1 full custom e-cruiser) & I am always thoroughly blown away by his ability to create new, innovative & totally unique frame/fork/handlebar combinations & yet still maintain a core “vibe & feel” for all his work. The fact that he does his own bends, can use TIG, MIG or braze really makes me wish I took auto shop back in high school & learned how to properly wield a welding torch!
The Man!
Custom bars, monark fork, 80mm rims, LED light, wood tank insert & lay back seat post.
Before/After
Original 1 spd. Pedal cruiser.
Final assembly
Odds & ends.
Finished project. Dual 52V/18ah batteries, 1300W front hub motor, 38mph., 60 mile range.

Cruiser2112 So, RUSH fan? I hope
All very cool, not my thing per se but I get it and the artistic massaging it takes to do those is staggering, nevermind the blacksmithing, fabricating finesse and so much more.

Yep. Additionally I try to take into account tire sag, a bigger tire will lose more height with its lower pressure. So a 42 could be closer to 38mm height when ridden and a taller rider using 175 cranks brings the ground clearance equivalence closer to 70mm drop.

Spring of last year my wife and I were in Sacramento for a couple of days and walked through a park where there was a lowrider bike show. Think I'll pay much more attention to the work in the bikes if I ever get to see such a show again!

mstateglfr, I use my wife's kitchen counter top as a flat table. It is quartz type, with quartz and resin molded into a very flat surface, and then polished flat. V blocks and a measuring device is all it takes. To cold set alignment you need to come up with a system that does not use the counter top as it will likely damage it.. I use the floor and move between it and the counter to bend a measure.
I braze things up using a Park repair stand, shop type with round base plate and two heads. All in all, it works as long as you are not into doing things quickly.
