Reconditioning a Relmac lathe

[BillTodd]

What you need is a portable boring machine that'll go down to your spindle size (Unfortunately my ancient Buma bar is 2" minimum)

The smaller ones used to be common place in motorcycle and scooter dealers (in the days when you could get your machine re-bored for two shillings and tuppence). Any long established dealers in your area? They may have one you could scrounge?

They're still being made, so there's still a use for them somewhere:
