I was just wondering out of the HF 20 ton A-Frame and the H-frame, which one is better. I don't want the frame stress out when using it on a part and one when it would have a enough space to put parts in.
Whats better A or H frame press

I've had a few different size H presses, and they were fine if you used them within their bounds. I had a fairly big one most recently and despite being Chinese, it was pretty stout. The most important part is that the cross piece that you press on is strong enough. I had a little 12 ton that the piece would flex and drop your work in the floor if you got much over seven tons. The larger one I had was much better built.
I have an H frame press. I have seen an A frame press in person. Because the ram is supported, it appears to have less slop. The H frame press has more working distance.
If I was going to buy a new press, I'd buy the kind where the pump and ram are seperate. This type has the advantages of both.

So would the a frame last longer, since it built a little bit better ???

I think I would prefer an H frame myself. The H looks to have a better range and capacity to it.

I would get the H frame. The press does have the power to bend the beams. When I get one, i plan on reinforcing the beams. Still, way cheaper than building your own.
Unless the ram can slide side to side the H and A are not all that much different in function or longevity based on frame type. If the ram can be moved side to the H had a leg up as you can press larger odd shaped things.

What would you do and where would you reinforce it and how.

Most damage I've seen is the bottom beams spreading out. They don't bend down that much. I figure I would probably stitch weld/plug weld another 1/8" sheet on the vertical part of the beams, then weld in a 1/4" or so thick horizontal piece an inch or two below the top horizontal part.
I would do similar for the top end. I don't think it would be necessary for most automotive use, but I'll probably be doing more than most, and I've seen where others have failed.

I have the 20 ton H-frame. Make sure you check that the ram is at a 90* angle to the frame. I had to go back and get another piece because the ram was so crooked. It makes suspension and transmission bushing work very easy.
