Setting up a jig with no reference points is sort of tricky. I think I’ve got the headtube in the right place but I’ll mitre the downtube, get that at the right angle and then be able to fine tune headtube height.
I didn’t consider any of this when thinking about how a jig would work but now I can see the benefits of having separate axis adjustments and built in measurements. It would help to have the bottom bracket in a fixed position rather than the rear axle but it’s all workable for now.

Seat tube cut and in. Downtube next, then top, then chainstays. After that I’ll figure out where the cables go, drill then braze the cable routing, tack the whole thing together and then light it up.
Progress is slow whilst I’m learning, measuring thrice, cutting once. Cutting long and creeping up on it with files.Seat tube I’ve left about 15mm long as there’s plenty of butting at the top and I wanted to leave enough at the bottom. Better too long than too short

Looks good. Where did you get the machined parts for the fixtures? After having spent 3 years failing to finish off my jig I could probably do with getting some parts machined by someone else rather than having that job lurking around on the Things To Do list for another 3 years.

Do you not have a lathe and a milling machine in your utility room? Ha

Banging. Show more work with the cutting and the stuff. rep for doing this at the dinner table.

I do indeed. I have all the tools required to make such things. However, I don't have the time to actually use them. This week I'm averaging 3 hours sleep a night, although admittedly that number is skewed a bit by the fact that the figure for Sunday>Monday was zero.

Ah I see, fair enough. Look after yourself. Health and family first, then bikes 👍🏻

I found a place making similar stuff in the uk too but it was last night and I was struggling to make sense of the website, hold on I’ll try find it...

Right on, girlfriend strongly disagrees but wants me to succeed so she can’t have it both ways.
Sure thing.
Here’s a pic from before the cutting where I’d measured all my butts so I know where I’ve got space for cuts
I’ll document some more progress tomorrow

Crazy talk. Bikes first, then work, everything else can go hang...

Tubing is Columbus Life with the exception of the seatstays which are something else as they’re a nice slender 14mm

Flatmount brake
how are you going to align these?
-
• #371
With great difficulty. The left chainstay is pre-flattened to accept the brake mount but there will still be some fiddling to get it right.
I just need to look at the tech docs and figure out the distance in X and Y of the brake mount from the dropout face and go from there -

make something that does the same job as this? https://www.incepi.net/products/flat-mount-fixture

Paragon has clear instructions for that: https://paragonmachineworks.com/files/public-docs/BK0031M.pdf
Did you get the short taper gravel chainstays?
-

Mixing inches and mm 😱
Yeah they’re Life S-Bend CX (seems to be called CX/Gravel in other places)
-
• #375
Yeah yeah, just multiply by 25.4.
I'm curious how it will turn out, I couldn't stomach the look of the short taper.
