Me and a buddy did one that had a bit more tube than that, on 2nd gen runner, including the sliders, bumpers, and wrapping it around his backhalf he did, in porb 18 hrs.
Granted it was our first cage, and like eveyrones first cage, it had bends that could have been done better, bends that didnt follow lines exactly, and bends that were off. But it works, and it was a lerning experience.
I think its doable in 2 days if you had a helper and worked hard. That cage isnt complicated, its all coming off the sliders, and the front part is all simple bends.
