So the titanium (?) plate stock sandwiched between the standard and the lensboard slides up and down (with a little bit on it to keep it sliding in line with the standard channel) and is held on by pulling it against the standard by the compression force of the thread on the knurled knob (?)
Meanwhile the milled outer knob has yet another threaded bolt that goes through the middle of the rise knobs construction, loosening this allows the wooden lens board to rotate with respect to the first plate mentioned above, which acts kind of like a second tilt only 'standard' (?)
If I have it right - then,
cool ! I like, and with the mill and lathe here reckon I can give it a go...
But exactly how does the tilt knob not bite on to/compress the rise construction and cause it not to be a catch 22 when you're back to a one knob tilt/rise combo of a more conventional system ? Some kind of system of spacers, what not and something simple I am yet to crunch with my grey matter ? I think maybe I can learn something from the way the lead screws on my lathe are set up here...
Anyone keen to disassemble one and photograph it ??? - ok, no, fair enough
