Can I add a 20 Ton press to a 6 ton harbor freight frame
Do you mean switching the 6 ton jack for a 20 ton jack? I would not try that. Once I broke the frame of my 6 ton jack by overturning it. Vince
Very unsafe idea, the HF frames are engineered for the minimum requirements, 6tons. It will stretch even more with higher forces, and sudden release can be catastrophic ( such as disc cutting or pancake dies).

Listen to Phil - he know more about presses than… anybody.
I’ve trashed a harbor freight press just with small dies.
If the HF doesn’t work well enough - get a good one.
