Since we're on the topic of rings and cylinders, i looked in the manual and couldn't really find anything specific for this, but what is the correct way to get the piston with the rings back into the cylinder?

The service manual suggests a piston block to hold the piston evenly when inserting into the cylinder, but it doesn't mention a ring compressor or anything. Is one necessary?

I know our cylinders are tapered at the base as to allow the rings to compress on their own as the piston is inserted, however i was having a bit of difficulty getting the first piston in and the rings to compress, and don't want to force it without asking my more experienced montage here, and risk the possibility of damaging the rings or cylinder walls.
I did put a generous amount of oil on the cylinder walls, piston sides/skirts, and the rings as is necessary when inserting them.

maybe i just need to quit being so pussy-footed about it and just manhandle those bad boys back into place.
