I decided to make this frame as an aluminum version of my steel gravel frame, since I was happy with the handling of that frame and it would be an opportunity to see if the aluminum version would feel any different from the steel.
The mitering and fit up of the tubes was the same as any other frame, except I didn't have any 42mm tube blocks for the down tube, so I 3d printed some to use for holding the tube on the mill and to keep the miters in phase. (I don't have any pics of the tube blocks to post here, but they are on my Instagram @
Starrcycles). You can see a bit of one on the downtube, in the picture below.
