    Hi Noel,

    Re: MiniFuller 2 cos build details

    All the cylindrical rules made on the same principles, just need to get the size correct. Need editing software ( I have ancient photoshop 7 elements which does the re-sizing ok. Bet there are much better now).

    Let me know if you need more details (bound too, I suspect  my intructions may be a bit minimal!)

    I now think that Wofgang's custom built tubes may the the way to go,I didn't know about these when I built mine with simple, virtually no cost PVC drain pipe off cuts.

    My computer generated scales were courtesy Wayne Harrison, but I have not been able to contact him for the last year or so and not sure whether he is still active. (his website details in the intructions).

    Anyways, good luck! I got imense pleasure making the Bygrave and the Fullers and ditto the results from using them for celnav!

    Best wishes 

    Francis
