Jack:
It's nice to know I wasn't the only one to try removing rear axle bearings with
the HF A-frame. I probably would have tried exactly your method (using
platform on the bottom) but my axle was just about an inch too long to do even
that. If I have to do this again, I'll end up building a frame (or jig)
similar to the one you proposed so that I could raise the whole unit to accept
the axle length, open up the area to accept the bearing width and press against
the floor.
Oh, and I forgot to mention, I replaced all stressed bolts in the frame with
Grade 8s.

Same thing here, except the bottom was the issue.
Normally, when you press, the work piece rests on a heavy
duty steel platform. The platform is supported by two
pegs that go through the main legs of the press, distributing
the force of the press downwards.
I sized my HF A-Frame press so I could press RX7 rear axle
bearings (H-Frame was too small). However, because the
axles are so long, they won't fit in the press with the
press-platform. Therefore, I made my own platform
out of wood and metal. However, this platform ended
up resting on the bottom cross-brace, and ended up
distributing the press force sideways, against the
legs, instead of downwards, towards the floor.
The outward force extered itself on 4 grade 2 bolts,
which promptly snapped. Grade 8 replacements
were sufficienct, however, when I have to do axle bearings
again, I'll make a custom jig so that the force
of the press is exerted down into the floor, instead of
sideways.
