Mirroring a part results in unnecessary lines

Hi,  I'm modelling a fairly simple tool-post that is symmetrical about the diagonal.  I have modelled one half and then mirrored it to create the final version, but in doing so I get a vertical lines where the two half's meet, strangely I don't see an equivalent horizontal lines.  The model is in my 'Smart & Brown Model M Mk1' folder and entitled 'Tool Post'.

Any ideas to resolve will be gratefully received.

    Can you please share a link?

    MB - I make FeatureScripts: view FS (My FS's have "Official" beside them)

    Select "Add" not "New" in Mirroring function and select your first half part as Merge scope.

    Hi MB - this is the URL for the model: https://cad.onshape.com/documents/afcae641e428cad745413fca/w/fd85d0d9190e07fbb3d88655/e/0edef1eefcbe8d81d146b68e
    I'm not sure whether that is what you want though? Can you explain what I need to do if it isn't.

    Hi Krz, sadly that is what I had done already.  If I create a New part then I have lines on both the horizontal and vertical surfaces.  When using 'Add'  its just the vertical surfaces.

    I'm confused.

    Thanks for helping.

    Not sure, may be a bug.

    In the mean time, you can use "Replace face" to knit those edges

    Thanks to you both for investigating and identifying the flaws in my drawing.  I'm returning to drawing an old lathe after a 2 year break so having to relearn OS.

    The help is very much appreciated.
