standard press works? I don't own one, but have been needing to get a small press for all the other crap I end up wanting it for.
Not sure what you mean by standard. I was using a typical hydraulic press. Looked similar to the one pictured below, but ours is a bit older and much better. Like I said I forgot to bring the camera to the shop

I don't particularly care for the press below, the upper beam tends to move around a bit.
Our press has a hydraulic ram bolted to the the upper beam and is fixed. The nose of the ram has a star shaped wheel to make ram length adjustments up to about 6 inches. The press below can get "sloppy" if you are not careful.
There is quite a bit of resistance pressing the gears on the cams and then pressing the cams into the bearings (after pressing the bearings into the plate).
When you do it, take note that there most likely will be shavings from the pressing the need to be cleaned out.
