a wip that I share on several forums
integration of a 91mm cissors on an 84mm
it's not the only method, just how I do it
the initial theoretical project
small reminder of the axes
91mm --> 2.5mm et 2.2mm
84mm --> 2.2mm
the 1st layer will include the famous scissors and a large dish.
I drill the plates on the axis which receives the scissors from 2.2 -> 2.5
I reduce the size of the cissor blades about 0.5mm less
I use an old model of chisel with screws this will be easier if the cut generates a little play
it is necessary to keep the fat because if one proceeds to the shaping only closed cissor
we were surprised to have an unsightly dish.
the reduction in size involves the overlap of the 2 blades
for the shaping of the spring it is empirical.
it is necessary to arrange a housing for the branch when the cissor and in the handle
retouched the height of the locking notch, keeping in mind that the small spring of the cissor works in reverse.
with the consequence that if the force of the small and greater than the large the position fold in the handle and impossible
made a new stopper at the rear of the spring.
and take the height of the spring for which does not exceed dimensions.
the other layer will have a large blade, and the small flat screwdriver.
reduce the thickness of the flat screwdriver from 2 mm to 1.4 mm
and manufactured the corresponding washers
one of 1 mm and the other of 0.4 mm
I turn the can opener into a bottle opener, more useful for me.
practice and theory are two very different things.
we eat a little material here, a little there, we are wrong, in short the tip of the chisel comes out a little closed nothing bad I had planned the thing a little with the lug of the spring protruding from the plate
but as I am picky I added a small boxwood wedge which forces the compression of the chisel entirely in the handle
well I agree it's not perfect, and I should have kept the inclination of the initial slope.
and as everyone has certainly noticed, I replaced the corkscrew with the awl, the edge does not touch the spring
but there is a Slight lateral play because if I reduce it (the play), the large blade and the bottle opener rub.
I remind you that the rear tool plays a spreader role to prevent the springs from getting stuck.
punch 2mm thick
2.4mm thick corkscrew
spring thickness 2mm
