Hi Brian

Thanks for posting your method of tubes for the MHR1, thats a great idea, just for clarity is it two pringles tubes and one Saxa salt tube for the outer scale, also could you give me an idea of the size of aperture on the Saxa tube.

Sorry about the questions but I am so keen to make on of these replicated MHR1 slide rules.

With best regards

Steve Gillion
