Vincent, my 3 stud QD looks to have been spot welded:

Paul, At the off side I dont see any welding marks, the drum side however looks to be swaged on to the tube.
Punch marks are mine for reference.
Best bet will be to remove the off side I think.
Thinking about the needed tooling now..

Bob, here a your pictures! , and yes, I can now verify that the flange on a QD hub is pressed on.
I only went a tiny bit bezirk on making these bits to get it off :shock: + that I like things to be substantial .
On the positive side; I now have forever a nice set of special tools to take QD hubs apart :D

Above and clockwise from 10 o'clock;

Flat 12mm plate with hole large enough to pass the off-side flange through.
70mm high and 230mm in diameter slice from a old fire extinguisher to place hub in.
solid bit to press down the hub's center tube.
2 part clamp, slide fit around the hub's center tube.

Place under fly press and in no more then 2 seconds, job done.

Now on to making extra flange to take those 3 studs and 9 dowels..
Oh, small detail: this will be the one and only 40 spoke 3 stud QD hub...

After the work that you have gone to in order to press the hub apart, surely you can now machine a new flange for 36 spokes and press that on. (if you had not have told us we would not have known but now that we know someone will forever be pointing out the error.)

David, very true.

侘 寂 This beautiful by imperfection hub will from now on be known as the Wabi Sabi Hub !

Well, I learn something new every day . . .

"In traditional Japanese aesthetics, wabi-sabi (侘 寂) is a world view centered on the acceptance of transience and imperfection. The aesthetic is sometimes described as one of beauty that is "imperfect, impermanent, and incomplete". It is a concept derived from the Buddhist teaching of the three marks of existence (三法印, "

I thought that 'Shinto' was the Japanese religion but it appears that Buddhism is more prevalent nowadays . . .

"Shinto and Buddhism are Japan's two major religions. Shinto is as old as the Japanese culture, while Buddhism was imported from the mainland in the 6th century."

Thank you for the pictures, Vincent, I'm glad it isn't only me that spends far too long making special tools to do 'one-off' jobs (you should see my lovely machined Ariel Clutch Centre puller and the milled plate on which I turn Tiger Cub brake shoe linings to size) :lol:

A lovely job, I look forward to pictures of the completed wheel which hopefully won't be imperfect, incomplete or transient ;) .

Bob.
