Thanks, good to know. Nice jockey shift.

I made holders for my lathe for my Park facing/reaming cutters. That allowed me to handle very long headtubes and the tooling was easy to make.

Plus, you get to experience the adrenaline rush of reaming a whole frame in the lathe!

I’ve been working near a student workshop and we sort of shared a lathe. My spider sense is been tingling since then when it comes to putting long objects in lathes. Maybe this will wear off, now that I’m away from those guys. It must be an intense moment, when the frame is almost finished and there is a possibility that you will butcher the whole thing.
Just a quick update wheel wise. Pulled the trigger on a pair of 349, courtesy of our friends down in the land of the great wall.
I opted for the 9/10/11s casette compatible option, steering away from brompton as suggested. Still on the edge about the rest of the drivetrain, leaning towards a 1x9. I have a nice deal on a whole Sora groupset, so I’m tempted just to slap on a big chainring on there. Will probably need a 60t to get me to my usual cruising speeds.

Hi peeps, long time no see… Sorry for leaving this topic dormant for such a long time.
I’ve been working away on basically everything except the bike. Grown up life sucks…
It’s never left my mind though. So I made a couple of gear decisions and fashion choices.
I went for a 9 speed 11-32 casette paired with a Sora derailleur - this will be a small pain as I’m planning to take the grey oxide off and polish this thing, since I couldn’t find a chrome one on the market to save my life.
I found a cool Sunrace indexed bar end shifter for shimano 9s
As for the general design I decided to add a second horizontal tube to the frame to add weirdness and went with a mono seatstay. Here’s a render of the general idea - by far not yet 100% accurate.
I’m finishing up my frame jig, as it needed quite a bit of upgrading.
Also, gear wise, I got a set of Shimano 105 Golden Arrow brakes and levers. This should make things stylish, will need to give them a good buff though.

Some work done, still a bit to go. I took a leap of faith and went for a bilaminate headtube and seattube. After a long-ish filing session the faux lugs are taking shape. Also simplified the rear triangle a bit.

Here’s the the ridiculous rear triangle I came up with. It really looks mind boggling due to the overall proportions of the bike.

Also the fork got chopped and I performed a steerer extension procedure worthy of a south american plastic surgeon.

For my first attempt at making stainless half lugs I think it came out not too shabby - I made notes to improve. It was a pain to get it to look presentable, my hands were “tired”

Here’s the first mockup, tons of clearance for a big chainring, which is good because the first test ride proved the 56t is not too much at all for this wheel size - will probably go with 60t

Ready for the first wonky ride. Did not have the time to do a proper fit (the mast needs to be shortened about 40mm) nor did I connect the brakes - just had to try if it even is a rideable bike, so heel to concrete brake it is. Got tempted to mount a moustache bar with some old shimano golden arrow brakes and levers. Might go with a different cockpit version later, I’ll probably make a stem/handlebar combo.

Finally had a chance to ride it properly, what a blast!
I will probably build a custom stem, right now it’s like riding in the drops. Maybe a stem/bar combo?
And of course a front pannier rack is in the making.

This looks great. What’s the front centre like? I built a 20” wheel polo bike once that repeatedly threw me off the front when I used the brake. F-c too short for the low front axle.
It’s 572,5mm. Didn’t try to pull stoppies yet, to be fair I’ve got some antique brakes on this thing with stopping power I could only describe as placid at best. It’s a short small wheeled bike, I’m aware it will have a greater tendency to buck when stopped abruptly. On my previous minivelo I went the other way a bit too much, moving the saddle almost exactly over the rear axis. This made it very hard to take off quickly without a unwanted wheelie.

Haha, touche.
I would agree to an extent…
Decided to flip the moustache bar upside down. This gave me an 80mm rise and a more city appropriate riding position (your mileage may vary). Picked up these very simple skeletonized brake levers at a very good price, they have a light vintage look to them - the adjustability being a tradeoff.
Next steps:
- A pair of fenders - I’m afraid brompton’s offering will be my only available option in the 349 range, any suggestions are welcome since I’m not a huge fan of the brompton fender look
- The front rack and pannier of course. I have a beautiful BROOKS Scape bag, only need to make a stable rack with a quick detach option

Oooo Tektro FL 750 levers! My absolute favourite brake levers I’ve seen yet. I put the black version on a friend’s bike and ever since then I want a silver pair for a bike I don’t have yet. I’ll probably use them when my first frame is done.

Mine too! Just a surprisingly rigid chonk of metal through the fulcrum and zero consideration for appearance features that don’t add functionality. I for one like the look of functionality.

For fenders on mine, I cut in two and re-radiused a fender from a Gazelle 29” bike. That was mostly done with some wooden blocks covering the jaws of my vise, and working my way around widening the fender to tighten the radius. Then, some Velo Orange fender hardware and 6mm (iirc) steel rod for the stays.
