    Francis, thank you. Though I now lack the tools (and probably the patience) I'd very much like to get an idea of how you went about making these lovely things. So, if it's not too much trouble ... 

    Just one will do. Maybe your favorite?

    Thanks again,

    Hewitt

    Hi Alan,Hewitt, Brad,
    Thanks for the email requests.
    Please find attached photos and build instructions as requested
    The build instructions relate mostly to my Bygrave replica done several years ago, but the methods are the same.
    The modified Fuller 3 just required some scale replacements on the original tubes.
    The first old photos show the original Fuller 2 with innermost tube devoid of scales and the middle tube with log and sines scales. Plus some other slide rules.The new fuller 3 has sin/cos scales on innermost and middle + tan scale on middle. The outer scale is the original C/D type log scale for general multiplication and division.
    I find the big Fuller 3 works, feels and looks great, better than the mini version. The only issue is the size and potentially vulnerable brass cursers.
    Best wishes
    Francis
