Order of procedure and metal state
Hi All,
I have a 2 questions so thank you for your help.
Thank you,
Tom
I have a 2 questions so thank you for your help.
- Would you say that normally the correct order of procedure will be to first Bend the tubes and then notch them ?
- For an aluminum frame that will go through quench and aged to T6, in what state would you order the tubes from the supplier the “O” (Annelid) state ? or another state.
Thank you,
Tom

For a production bike, I would say the order of bending and notching doesn't matter. For one-off bikes, I would bend first, notch second
Sorry I can't help with the aluminum

Agreed, especially if the bending is near the tube ends. Depending on how the tube is being held during the bending some deformation (other then the intended bend
) can happen so a pre mitered end could drift from best fit up. Andy

I suggest cutting the tube to length post-bend. In an earlier life, there was a tubing manufacturer that refused to do this and the tubes were never right. We eventually didn't allow him to bid on jobs.
