Re: [woodandbrass] G. Hare Improved Pocket Camera - tripod socket
to add to my previous post on threads, and people think a "thread is a thread". and this is where the problems come in.
especially in older equipment.
below is and insight in to part of the design variables in a Thread... what is not shows is often the metalurgy is also an element. that is why they came up with British Standard Brass Thread, for Brass (naturally) and why a Whitworth designed for steel, with a different angle wont fit. below shows and angle of 30' but this can also vary up to 55'. etc...
and this shows that when every manufacturer makes their own thread, even though the look alike, may have the same pitch and dia they may not have the same angle of the thread... etc.
this does not help, but next time you have what looks like a 1/4" tripod socked from the 1880's, don't try to force a modern 1/4" thread into it.

- Clarence,George Hare was still selling his Improved Pocket Camera in the mid-1890s, so nailing down your camera's date may not be easy. It was available c1895 in both 4" x 5" and 3¼" x 4¼" format sizes, and Hare was still at his 26 Calthorpe St. address.Cheers,Rob McElroyBuffalo, NYOn Apr 13, 2011, at 12:06 PM, Clarence Rhymer wrote:
