    I thought that at first look, but it may be a perspective thing - planer could be behind whatever is behind the cardboard.

    If the "bed" has 10 ft of way length, there's a good chance it would be at least a 5' planer, could even be 6'.
    Planer tables usually travel past the ends of the "bed" both directions by a fairly...

    I already posted those options way back in post #2 :)



    Qualified it at the time, though:

    There are several online sites where it is easy to blow the picture up quite a bit more.

    FWIW I suspect we are all talking about the early round ram SB's; not the later imports that were essentially various spec BP clones with R8 or sometimes up to NT40 taper IIRC.

    Per my notes, i would also agree that in the heat of writing a response, one tends to forget some of the details.

    Perfectly fine machines at a fraction of BP price.

    All spindle tooling is modified from 30 taper. see SB forum various posts how to do this.
    Certainly better than (BP) R8, though a slight bit of...

    Condition of the ways is everything.
    no sense grinding away pads or chucks if the grinder is not true.

    But that is one reason i prefer to scrape pad, and chuck base, as final op between mating....

    A non-flat pad and a non-flat chuck bottom will bend the ways when clamped up.
    So everything is a matter of degree.

    It is most practical if the pad is parallel to the ways. And flat
    It is most...

    To remind you, this has been addressed several times and we all agree.
    I have never suggested an HLV-H, that was others.
    In the post you quoted, it was merely a comparison of quality.

    Does Rivett 608 top 350lbs?

    Lots of old Hardinge split beds and similar makes out there.
    Though perhaps not so easy anymore to come up with the threading and power feed parts and gears.

    No connection, these guys come up sometimes on the airplane forums.
    They even make pre-cut kits for weld yourself. Worth reading the claimed tolerances.
