    Bought this nice piece of hardwood to size but need some more. The timberyard said they could sell me 70mm wide bits of hardwood but is it easy to cut that in half with a circular saw? I mean I would have to make a piece of baton as the fence and is 70mm wide enough?

    How would we know if it's wide enough without you giving the dimensions of what you need?
    In half in which direction, Length width or depth?

    Depends on accuracy needed

    A bench saw will do it accurately compared to a hand held circular one
    Most hh circulars have a T guide that you can use but it tends to be not so good
    Or find a long bit of metal to use as a guide

    Shop around? See you f the local school have a wood workshop and the tech would cut it for you for a bottle of plonk?

    The width so half of 70mm is two 35mm cuts. But setting a fence to do it accurately would be difficult wouldn't it?

    You won't get two 35mm from a 70mm , blade will be 2-3mm wide.

    As said, you need to allow for the cut

    But if the loss is acceptable, practice on an offcut to get the setting right

    first thing to do really is ask the timber yard if they can rip it down as they will only generally quote whats in stock

    Nigh on impossible with a hand held circular saw. It needs to be ripped on a proper saw table, and as someone else has mentioned you have to allow for the kerf of the saw. You cannot get 2X35 out of a piece of 70mm.

    A band saw will give you close to 2 x 35mm pieces.
    The tuff saw supertuff premium blades are only 0.8mm.

    Not impossible, just difficult, as any site carpenter will probably tell you, and difficult to do with any degree of accuracy unless you jig-up. Helps if your saw is fitted with a decent rip blade (low tooth count) and dust extraction
