Project Description:
We need a mechanical construction that shall give a simulation when a shoot is fired from a rifle. The user shall "load" the rifle, this moment span a spring so when the user then pull the tigger, it gives a blowback an make a feeling of that a shoot have been fired. To span the spring enought I thing we need to use some concept around "block an tackle". The construction must work millions of times, and all fitted in a dia 32 mm and like 30 cm long tube. We looking for a mechanical contructor that can help us with this, we have more comming project as well . We wan a drawing so far, a construction solotion.
We have stocks etc that this have to fit in. So, this is a "help with construction " project. we like to have DXF files of the construction.
It is important that the feeling when loading the system is good.
