Fascinating, hate to think of the possible price. robH. ----- Original Message ----- From: "Richard Turner" <richardturne...@outlook.com> To: <viphone@googlegroups.com> Sent: Friday, September 20, 2019 1:44 AM Subject: Re: accessible measuring app?
The below came from the Vision Aware site of AFB. The Click Rule The Click Rule is a metal tubular device slightly longer than 7 1/2 inches. A 7-inch threaded rod is inserted into the tube. A knurled locking knob is screwed into the top of the threaded rod through a long slot that has been machined into the tube. [closeup of someone using the Click Rule to measure a board] The Click Rule As the threaded rod is extended into and out of the tube, a clicking sound can be heard at 1/16-inch intervals. The threaded rod has raised threads every 1/2 inch. The metal tube has two flat rectangular stops or fences mounted on it. One stop or fence is located precisely at the open end of the tube and the raised thread rod protrudes through it. The other stop or fence is positioned exactly six inches along the tube from the stop at the open end of the tube. The Click Rule comes with three 12-inch extension rods that screw into the end of the Click Rule raised thread rod and into each other, enabling accurate measurements at 1/16-inch intervals, from zero to four feet. Additional extension rods can enable measurements beyond four feet. [The Click Rule with a one-foot extension rod in place] Click Rule with a one-foot extension rod The Click Rule can be purchased from the National Federation of the Blind Online Store<http://secure.nfb.org/ecommerce/asp/default.asp> and from Community Advocates Inc., P.O.

I have a 25ft "braille" steel tape, but it only has markings every 6 inches which is not really accurate enough for my work, and I haven't found any sources for something more accurate. -- The following information is important for all members of the V iPhone list.
