How long’s the top tube?
If you're planning on selling as a Hulsroy special®, I might be interested if it fits me. :)
I'll let you know but there is no real motivation for making something I can't ride myself. Then I am better off making bike for people from scratch
The cargo bike BB shell is toast. I bought new taps to try and chase the threads but they are the wrong ID for my tool. I am never going to be able to fix it by cutting threads so instead I have bought an adjustable reamer and I will ream out the threads, tap for ITA threads and silver braze in this ITA to BSA adapter.
Sounds like a good fix. How did it get toasted?
It has deformed from the intense heat from TIG welding of the yokes.
I was being a rookie by not using a heat sink. I thought it would be alright as the rest of the frame was welded up.
Just to be sure, ITA threads don't have counter-clockwise threads on 1 side right? BSA does.
But I am not too worried about that as I will be fixing everything in place with silver
Not bike related. But sanity related and therefore important for getting back to welding bikes.
Ooh, that is pleasing, at least to my slightly ocd head.
Is there a thread for sorting porn?
Maybe this is more Functional Sorting, not sorting porn, not anti sorting.
Progress. I bought a giant reamer and am now tapping the BB shell to ITA threads and will the silver solder in ITA to BSA threads adapters
I just need to add silver and heat
Also. My tune cranks cracked so I updated the whole thing.
Nice fix! How easy was it to re-thread to ITA? You have to remove quote a lot of material, don’t you?
Reaming was surprisingly easy. My ITA tap is from 1970 and blunt as fuck. So that bit could have been easier

What paint are you planning?
How would you go about cleaning a surface like this before painting?
Ta. Fucking happy it is no back on track. Expensive mistake but nice to know I can fix that sort of stuff.
Paint I was going for RAL 1027 Curry Yellow. I am having a cross bike painted this colour right now and if that comes out dope I might go for the same and do a rack for towing the cross bike after the cargo bike.
After seeing Sam from Stayer's foldable MTB this weekend I have also got an itch to paint something brown. Maybe matte brown
