Converting to 130 quid it seems like the simplest method right now
It cost me £70 quid to have my gear sprayed and ground, so £130 doesn't too bad at all (it's a very nicely made gear ;))

Just as a check (in case Feeler haven't copied hardinge exactly) ,it'd be worth visually comparing my gear with yours:

The large bearing is 3/4" ID and just under an inch OD (presumably for a press fit)
According to my parts list the hardinge bearing part number is now FLH1481 (Replacing 6700) . I found an equivalent double seal needle roller at Simply Bearings but chose to make a bronze bush instead.

I can't remember the sizes of the small end (I'd guess 7/8"). Hardinge part is LH4144-1

The gear itself is FLH1402 (from mid '71 onwards)
