I agree. From what I know, The British Horological Institute and watchmaker schools in the Netherlands teach to work on watches with flat ground screwdrivers.
Hollow ground is useful for screws made of a softer metal such as gold and convex screws that you sometimes see in older watches and also sometimes used as case screws.
How are escapement wheels and pinion assembled?
Would instaling the pinion onto the escape wheel on staking set, suffice? Or the joint should also be shellaced?
I used to just glue the joint, but do expect some sort of corrossive effect from the glue.
Thanks in advance.
In school we uses this one, also to make hollow blades on a screw driver.
But is very expansive.
This one is cheaper, but don't know if you can use it on al screwdrivers from the Bergeon set, because it only have 3 holders.
But this is wat you really need:
