| John Cooper posted This was another Mesta Mill we installed in 1954. We used to deliver 8" x 8" Blooms to the Billet Mill, and these 2 stands allowed us to deliver 10" x 10" Blooms, saving 2 passed on the Blooming Mill. |

Mike Bready posted two photos with the comment: "Found these prints years ago,decided to share. ( Mesta ) not sure what type of lathe it is but it’s of good size for sure."
David M Stockett: I also believe that machine was installed by the govt. During WW2 to bore the barrette gun barrels.
Michael Stadler: She is a beast...located at mesta (WHEMCO) In Homestead PA. Was part of the crew who retrofitted it back in 2008..got upgraded w Siemens 840D cnc for the remaining saddle 1...
David Finch: To me the most amazing part of Mesta was the ability to build machinery needed to machine the Mill stands and housings that were ever increasing in size. [Every time I see a huge machine tool I think: but how do you make that machine?]
David M Stockett: I Worked there for 10 yrs, I remember that machine. I don't remember the stats, but it would bore a 8" center hole thru rolls, columns, etc. As a welder, I had to cut the cutting head off for a new one. The guy that ran that machine worked 5a - 7p everyday...
William Wimer: They called it 100 it lath it was built by mesta machine still at Whemco that machine is tree panning Emile, ROLL pouring out the center
Stacy Mays: I think they used to make shafts for the props of ships on them too.
Carl Mark Chapmon: We had lathe that were bigger they spun four hundred inch OD for turrets for battleship has name engraved on machine. It was huge machine

| Sean Brady posted Machining a gear at the Mesta Machine Co, WestHomestead,c.1910. The size and scale of steelmaking technology at the turn of the century fueled the almost overnight industrialization and urbanization of many parts of the country. Today, that same technology presents a new set of challenges for those who hope to preserve it. [The comments discuss why it was cast with two halves.] |

| Jim Rickard posted Mesta Machine 1913. Mesta supplied heavy steel mill machinery for mills all over the world, this is the type of giant forgings and castings Mesta was famous for. Graham Whitfield: There is a great story about Mesta and a British Steel Company called John Summers Ltd. ( A large family owned Steel manufacturer.) In 1936 they began preliminary negotiations with Mesta regarding installation of Hot and Cold Continuous Mills to replace obsolete Hand Rolling Mills. In 1937 the Chairman of Mesta finalised the deal at the Savoy Hotel in London with a written estimate of $10 million on Hotel Stationary and a handshake. The Mills were commissioned on time and on budget and with strategic timing before the outbreak of WW2 in September 1939. Stephen Mcnally: the 42 and 48 inch steam beam mills in bethlehem came from mesta in 1907. [A comment indicates that Mesta was founded in 1898 in West Homestead, and they opened their New Castle plant in 1942.] |

| Dennis Barker commented on Jim's post Mesta Bull Gear being installed in a 80" Hot Strip Rolling Mill Granite City Steel. Jason Klootwyk: Dennis Barker this is a fabrication, not the original Mesta that would have come with it. By the design it appears to possibly be made at Horsburgh & Scott. It is always a cool sight working on these massive drives. |

| Skip Estes commented on Jim's post I was a welder at Wyman-Gordon years ago, they had Mesta presses and this 50,000 ton Loewy press. Impressive |

| Sean Brady posted Mesta Machine Company workers dwarfed by machinery, West Homestead 1940S Mesta Machine Company worked on a huge scale producing equipment used in steel mills and other manufacturing plants. Founded in 1898 when George Mesta merged two smaller companies, it became the world’s largest steel equipment manufacturer under one roof. The company made crushers, engines for blast furnaces, molded gears and massive forging presses, products that towered over the workers who created and operated them. [There are some interesting links in the comments about big presses.] |

| Jonny C Brando commented on Sean's post [There were some comments about wanting to what machined the top piece of the hydraulic press.] |

Here's the link to the entire catalog: https://archive.org/details/plantproductofme00mest/mode/2up Denny Paderewski: I like the way that they assembled everything before they shipped it.. Rick Rowlands: Denny Paderewski all machinery was assembled first in the shop then disassembled and shipped. |

| Robert Meyer posted One of my favorite Mesta themed photos. Delivery of Mill post, 50" X 96" Slab Mill Burns Harbor. Photo in 1968. Burns Harbor's Slab mill began operation on October 20, 1969. [Additional comments explain this slabbing mill was closed after both of the continuous casters were working.] |
Mara 12, 2024: Dean Amrhein posted the comment: "I have heard that WHEMCO in West Homestead, Pa. is closing. They are the last remnants of Mesta Machine."
Kenneth Treharn: Back in the day, I worked at WCI Steel, 56" Hot Strip Mill. We used only WHEMCO rolls. Great rolls. We got a new bean counter back in the 1990s and he had a brainstorm. They bought some "foreign" rolls and he cut back on the Standing monthly order with WHEMCO. The foreign rolls were beyond Junk. Back then, Companies were waiting in line to get WHEMCO Rolls. It took a while to get back to receiving our previously standard order. We were scrambling to keep production filled. Imo, WHEMCO were the best.
