Tom and everyone else who might be interested! I do still have plenty of tubes. Please refer to my NavList post #12496 from march 22. for the procedure. (quoted below) As soon as the money arrives via PayPal I will send out the tubes. I am looking forward to learning about your slide rule building experiences. best regards Wolfgang PS: I just tried my now almost finished rule for the first time and obtain a reasonable result :o) I am short on time now so the testing will have to wait for some more time. but it is definitely a thrill to see/feel it work > > > > > > On Mon, Mar 22, 2010 at 1:55 PM, Wolfgang Hasper > >wrote: Friends, > > > > I received the laminated paper tubes.
