harrier practive bomb - moving - lifting eye/or advice

[iainmaoileoin]

I have a harrier practice bomb  at home.  I need to get it to my bunker as a "gate guardian".   I have an LR and a trailer.

I live in the hills, my wee fergie cant lift the bomb on the buck rake.

My kubota digger will, but trying to get frame/chains to do a vertical lift is hard.  I did build a scaffold frame and and and...  nothing really works so far.

I see a lifting eye in the bomb - about 1+7/16 (37mm or so) using a very fine pitch thread - say 2mm or so.  I have no way to ID this thread to see if I can find a bolt that fits it.

If I could find a bolt to fit that I could weld up a lifting eye - or does anyone have an eye I could rent/buy/use etc etc.

Any advice is welcome.  Living remotely means that getting in a different lifter (say a fork lift truck) is very very expensive.

Clues?

Thanks in advance.
