First off you need a side cocking spring piston rifle, with a fixed barrel and a retracting chamber, the chamber has to be concentric to the bore, for an example of what to look for, do a search on an RWS/Diana model 52, this is generally the type you need.
First you must ream out a chamber in the breech of the barrel to allow the insertion of a .22 LR shell. (so the shell sits flush with the rest of the barrel.)
Then drill a small hole slightly off center in the piston face, tap a piece of nail into the hole in the piston and file it down so that when the piston reaches the end of the cylinder, the nail sticks out of the air transfer port in the cylinder, strikes the rim of the shell and ignites it.
That's all there is to it, nothing else has to be modified.
The reason some spring airguns aren't suitable is that the piston rotates during use and the air transport holes are off centre.
You may have some problems such as the barrel not coming off easily for drilling, you can overcome this by using a handheld engraving machine. (It doesn't have to be perfect.)
