That machine would make perfect sense if your main business was chiopping allthread, or if you had a mate who'd got one you could let you use it through a weekend. Otherwise what I'd guess to be 20 to 30 grand's worth of gear isn't on the cards.
4.500 seems like an intermediate amount. Too little for buying serious gear and too much for bodging if the nuts have to go on easily. It would be worth checking the suppliers to see if they could just do it.
Otherwise, I'd say that the way was to put the nuts on to less than 160 mm and then force them off with spanners when they were cut. It's an awful lot of mucking about though.
Then there's mwi's offer.
