What is this lens repair tool I keep hearing about ?
Does any-one have any details/measurements to enable me to make one up please.

Hello Tom,

I guess you mean the lens cocking tool? If yes, I built one myself. Please check out http://www.xs4all.nl/~wkb/Hasselblad/Unjam-tool

I pick one up from Bel Air Camera for about $10.[maybe less]

Get one through Ebay from Hong Kong. Very reliable source and cheap - it's not worth making your own.

I only created my own because I had most of the bits lying around already. It is indeed much easier to buy a ready-made one. Or just use a small screwdriver with some care.

A screwdriver can only be recommended for those who have a steady grip.
All others please use the special tool.
When the screwdriver slips from the slot there is a real chance the rear element of the lens will be damaged.

I used usual screwdriver without any problem.

I'm affraid of how to use it with my 2000FCM of my 202FA.
In fact I have a nice new macro ring I never try with my 20xx because I'm afraid if I make a mistake.

Isidor,

You're right not to try a screwdriver or this tool with a focal plane shutter Hasselblad.
You'll ruin the shutter, and they are hard to get replaced.

Onu,
SO how to cocking the lens when fitted on a 20xx body ?

Isidor,

When using the wind crank does not work (either 'normal', or using the double exposure unlock button), you don't.

Putting anything through the film gate, where it may collide with the shutter curtains, is a bad idea.
You can't use a screwdriver/cocking tool anyway, since the axle is covered by the camera's inner bottom plate.

Soo, no issue ?

I haven't had a problem as long as i have been using focal plane shutter Hasselblad cameras (not with the 500-series cameras either, except for one time, caused by a automatic bellows that was known to have a problem. Then the screwdriver was of help, after demonstrating the fault to the repair person).

But even should there be a problem: there's nothing you can do yourself, except try the wind crank with double exposure button pressed.
