Never seen any plans for a fed5. Everything I am trying only comes from notes and observations that I have noted over the last couple of years.
By upsweeping the axles I think I will only need 5"risers and I think I have nutted out how I can do it. I have set the axles at 45% which is less than the pacfic magic and a bit more than pauls yacht.
Got a fair bit constructed today (frame and axle ends for wheel barrow wheels. (Held up now for a couple of days can not find my 5/8" thread tap,have ot buy another

)using the same axles for all wheel sizes ---wheel barrow(have to turn up a spacer) 20" and 26"
Will post some pics when I get a bit further along.

Cheers
