Time to finish my racks. I got some Wolfman pannier bags last year and have been trying to make time to make some racks to suit. I used some 8mm bar for the outer frame and and 6mm bar for the 2 vertical risers. Some 25 x 3 and 25 x 4 flat for the attachments and should be OK.
I printed out a picture of the Wolfman frames off the web and scaled the dimensions from it. I didn't buy the genuine item because I wanted them a bit lower and further forward, and gotta justify the MIG. Cost about $10 + a day in the shed. I also changed the strap that goes over the seat so I don't have to sit on the buckle.
Will test this weekend as am off to the Wallerwang and the Hunter Valley.
