Lens Repairs etc

I fancy taking an old M42 lens apart, (just for fun - but maybe to try to learn a little).

Where can I buy the "tools" and kit from to do this - obviously precision screwdrivers are not a problem but how about the tool needed to remove the screw thread rings etc.

Any other tips really appreciated - apart from "don't do it"

Cheers

Tools are available from http://www.micro-tools.de/english.htm

the East German zeiss lenses are easy to dismantle and play with. Japanese lenses like the Takumars are more difficult (so I hear).

I took my Zeiss flektogon to pieces and was able to free its sticky aperture without any special tools at all. Unscrewing the rear element was a challenge without the proper whatsit though!

Have a look at http://www.mypentax.com/tak50_1_4.html for a blow by blow description of how to disassemble a 50mm Takumar.

Thanks for your replies

Started "hunting" on the web and found the following:

nice "bit of kit"

all the good "bits and pieces" seem to be in the States

I can just imagine that thing slipping and those nasty points raking thier way across the front element of someones pride and joy.
