    Re: Navigator's Slide Rule

    Ponoko, the ones who cut and etched the acrylic for the slide rule seem to have modified their list of materials since December, and the one I used (cream) is not there. 
    I have sent an inquiry to see if I can still get it or something comparable. The problem is that most of their acrylic is translucent which doesn’t work well with the fine lines on the scales.
    The light gets scattered and makes the paint filled engraved lines look soft like ink bleeding on paper.

    I’ll let everyone know as soon as I hear back.

    Enough "me too" posts on this topic. Sean Johnston, who has suggested that he may be able to produce some copies for sale, still has to figure out his costs and schedule and all that, and when he does, I am sure he will provide contact details so that you all can send in orders. But he is not "taking orders" and Navlist is not a marketplace for placing orders. So no more "me too" messages. 

    Thank you.
