    Yes, you can still have the topslide offset to get the benefit of the quick retract and use the cross slide for the infeed.

    The dual dials were available for all machines as far as I know (my HLV-no-H has them). The EM had the English+metric gearbox.

    But that's just my opinion.

    The J&S hubs should be 1 1/4" unless they are 'specials'. The trouble is that 32mm is also a standard size for more modern grinders.

    It's not 'full price'. It's 'fraud', or if negotiated down, then 'attempted fraud'. If the bill is sent by emai, it's 'wire fraud'.
