So much negativity about broaching with a hydraulic press. This is somewhat nonsense, in my opinion. I have a small 1T arbor press that is pathetically limited in height, and an HF 20T hydraulic press, which isn't, that I've used to broach maybe 50 keyways of various sizes and to press on/off gears and bearings on fairly long shafts. Of course, one could be a klutz and mess up broaching with either tool, but it's not much of a challenge to broach with the HF press, since you can control pressure very precisely with the handle, and for speed I've added an air/hydraulic cylinder.
Now if you had an arbor press like the one at H&W Machine Repair, yes, use that. Wish I did.
