M42 lenses on T2- or M48 mounts adapter

[ForenSeil]

Hi!

For my new DIY-Speedbooster project I need to screw M42 lenses into a female T2 screwmount or an female M48 mount.
Any ideas were to find an adapter? (I don't care about infinity)
Any other mounts than M42 would be also very intersting, like Minolta MD/AF, Canon FD,... and especially Pentacon Six or Kiev 88 etc.

Hm... How about a friendly chat
with Henry, the VNEXer?

I found a way -
M48-M46 step down (10€)
M46-M49 step up (I already have one)
M49-M42 reverse adapter (I already have one)
M42-M42 female female (10€)

The final adapter will be:
Short NEX-M42 Macro-Focusing Helicoid (45€)
M42-M48 step up (20€)
TS 2" M48 MC ED 0,5x focal reducer (50€)
M48-M46 step down (10€)
M46-M49 step up (I already have one)
M49-M42 reverse adapter (I already have one)
M42-M42 female female (10€)

expensive experiment

Now I'm looking foward different mounts. Only M42 lens I currently have is the old keeper Helios 44-2 and some lenses for bellows
