    Slide rule tubes now available
    From: Wolfgang Hasper
    Date: 2010 Mar 22, 13:55 -0700


    I received the laminated paper tubes. They look great, surfaces are very smooth, dimensions meet the specification.

    Compare the linked photos. I did not shrink them, so they are 2.5 MB each!

    Three tubes for cursor, cosine and cotangent scales plus a small bit thicker tube to slip on the intermediate tube for the base.
    A little grinding is required to adjust the interior diameter here, but allows for a tight fit without glue.

    Also linked is the current version of my drawings. I will make a pdf of it when some trouble with my pdf writer is solved.

    30 sets are available, in case of any unforeseen rush I will handle them first come first serve ;o)

    One set is 25 EUR

    Packaging (flat) 5 EUR

    Shipping within EU 8,60 EUR

    Shipping worldwide 13,90 EUR

    Up to two sets can be shipped with the given shipping rate, for larger quantities I will have to check first, however
    it will be considerably more expensive. (30+ EUR outside EU)

    So the "regular" cases are as follows:

    One set, within EU 38,60 EUR
    anywhere else 43,90 EUR

    I created a special email address to handle the distribution:


    it is registerd with PayPal also.

    I ask all who want a set of tubes to write an email to this address,
    giving the number of sets and shipping details. Please transfer the money in EUR via PayPal
    (PayPal fee is included in the given numbers).

    The tube sets will be sent out as private parcels and I am doing all this tube-organsing as a private person
    without interest and without warranty or liability of whatever kind.

    I am looking forward to comparing our results, may they be Bygrave or HR types.
    I would also be glad if we could join for the scales, Heins results look so very promising :o)
