not so weird, a rather logical mod...
Frank S. sent me this Hi-matic 7- it had a jammed shutter. that crap on the shutter blades is graphite powder... oil is a killer, graphite is not.
so- as usual, I got hyped. that viewfinder! c'est manifique! but, I always find problems- impossibly long wind stroke, stiff and loooong shutter release, it's not compact at all...
but tinkerer as I am, I fixed one- the shutter release. lemme explain halfway...
this camera has aperture priority. it has some rod coupling the aperture selector to the meter, and the aperture selector is kept up by spring pressure when the shutter release is not pressed. when you presse the shutter release, it travels a bit, traps the meter needle, then lets the aperture open up if necessary- how much it moves is determined by the needle postion. to sum up, all this stuff makes the shutter release annoyingly stiff and long... so I got rid of it.
I took out the rod and the plate things
aand the shutter release connects to a fork which sets off the shutter. I mis-aligned the two, the shutter release pin sits on the fork instead of being in between the uh, forks, of the fork. so what do i get for an hour's worth of tinkering when I should have been doing Physics problems? a shutter release that rivals that of my Canon gear. the stroke is short, it's light and the shutter is quiet. also, I de-soldered the flash contacts and never put 'em back, and I removed the eyepiece and in true Dragunov style, replaced it with electrical tape (thinner=better for spec wearers).
sorry if this is incoherent to you, it's a little late and the brain is fuzzy...
cheers.
