That's nearly it for the screw I have to turn the plain end down to .750", make a woodruff cutter to cut the key and then drill & tap the end for the securing bolt. I might just cut a straight keyway in it I don't see what harm it would do.
I bought the inserts from eBay, have 8 and 10tpi LH. I could let you havean insert if you need one Ronan though I'm unsure if it'll so down the bore of the nut.
Your machine is an absolute sumbitch to do the cross slide nut on by the way. I had one that was badly worn and the nut & screw had been carrying the cross table weight.
BTW You could look at this list for your thread size see if it's listed. The platform nuts are a lot cheaper than you're quoted.
