I built this one out of 4" Channel. The 12 ton bottle just sits there with a pocket for the bottle's ram to center it. The bottle can be just pulled out and a 20 T set in its place if there was ever a need. The ram for the press, below the bottle is in two pieces. The 1" piece can be removed and push with the larger 1 9/16" section. Only the table is welded and is supported by two 5/8" pins on both sides. The rest is bolted with 9/16" grade 8 bolts and with the 12 T has not failed me.
