How to fix loose shutter blade in the SEIKO shutter In FUJI GW690 ver. III with homemade tools.
In this video I will show how it's possible to put loose shutter blade (s) back in place WITHOUT fully disassemble the whole shutter. With the use of "Dental flush thread" to hold the small spring (s) in place so one can take the shutter assembly out of the housing.
But in this case I also show my special homemade tools that make things A LOT more easy.
