Friday mourning a semi showed up at my land. it had 49000lbs of pipe on it. i have over 10,000' of fence to build. so heres my issue i have 2'' od 1/4 thick to saddle and weld to 2-1/2'' sch.40. i have a plasma and a torch.but im considiring a 2-7/8'' hole saw in a gig on my drill press to saddle the 2''.... is it worth it to use the drill press? or will i just get better and better at saddling?

also not pertaning to the above topic
have yall ever welded rebar togother instead of tying it?
does any one know the aws spec?
and since the carbon content so high do i need in to use lo/hi?

thanks for your comments...
