Minolta MD to Leica M

Minolta MC and MD lens adaptation on Leica M body is relatively easily carried out so long as the principle of flange-back distance is complied on the way. The surplus distance, 43,5 mm minus 27,8 mm = 15,7 mm, must be compensated by any extension tube, if a precise infinity focusing is desired. So, I did it utilizing genuine parts, Leica M body cap and Minolta lens rear cap promptly, both of them are made of engineering plastic material those are capable to be bonded with organic solvent, Di-Chloromethane and Epoxy glue.
As for the vulnerability to the load strain for the plastic material here is proved if the lens weight does not exceed 400gr in total, the flange connecting accuracy would be maintained without deviation of the optical axis. And the advantage to form a breakable part here on conjunctive point is one of a stress breaker in case of undesirable accident such as falling down, probably the connective flange part of the camera body would be survived without any distortion by the destruction of modified plastic parts, Minolta bayonet female nails and also Leica M bayonet male nails?
