Thank you , I think suitable screwdriver does the job. Does it need to turn 360 degree ? Does it load the force to hand too much ? I am going to buy to my sister.

There are lots available at various stores and on ebay.

Screwdrivers work, until they slip and scratch the glass (a very fine repair guy told me a horror story about a client who tried to fix it that way).

I use an American penny on the rare occasions a lens needs manual cocking.

That's why my repair guy recommended.

I often use a quarter, we got rid of pennies up here. A quarter is a bit bigger and fits the slot well.

A larger screwdriver works well too, large blade so it fills the slot and does not slip around.

Ah , I could not remember what was the penny. Richer the state , they mint the abraham beard higher. When the no more money , they mint lower height and rescue 500 tons of copper. I was reading numismatic papers. Thank you. I think my sister can find a suitable euro .

The ring around the blade makes is safer to use.

+1 on that. Avoid screwdrivers and if you absolutely have to use one, be very, very careful.

Ironically, my 135mm is the only of my lenses which often (or at all) needs re-cocking - it trips every time I remove it from the bellows. And due to the construction of this lens, re-cocking will only work with a screwdriver (or maybe a tool like in post #2 above, which I do not have)

Something is out of adjustment with that 135mm lens. Time for a CLA.

Coins are the answer; an American copper penny (1982) and a U.S. nickel with a small squared-off slot, made by a small flat file, hacksaw cut, etc, ad infinity!

Use a fine file or sandpaper to smooth the rims rounded, so no misadventure with a sharp edge digs into soft optical glass or metal finish.

I have the Hasselblad tool and much prefer it to a sharped corner or edge, and a too easy to loose control handle.

IMO.

For all the work it will take to make the device that you want you would be better off looking for an ad like this https://www.photrio.com/forum/threads/hasselblad-flexbody.195224/ on Photrio.

It might be the Auto Bellows unit that needs adjustment, and not the 135mm. Remember you have to take the lens off the bellows before you take the bellows off the body, or the lens will release. The Auto Bellows has a telescoping sync key which can developed some play when worn, and not sync correctly, causing the lens to release anyways.

And it's much less likely to scratch the Bellows 135mm when using a regular screwdriver as the rear element extend well past the mount, so your screwdriver cannot slide out onto the glass. And its pretty much impossible to use a coin on that lens anyways.

I think a quarter is the new equivalent of a penny, at least from what I see on the prices of everything.

… and a Franklin is the new equivalent of a Jackson. Sad, isn’t it

Well, I never liked Andrew Jackson and I do like Ben Franklin, so not so sad.
