To everyone that has given their input I want to extend my thanks. I realize that this project is not the everyday welding job and therefore there are questions that aren't so easily answered. I have considered many alternatives and what I'm leaning towards at this point is a " divide and conqu...

Angus I apologize for not replying sooner, I hadn't noticed that there was a second page. We are planning something for either Broward or Palm Beach county. We are designing a shear, my partner is the one that has designed most of it. Because of non disclosure agreements that were signed ( it is bas...

Let me correct my previous statement.
I said that there are several companies that make these machines.
The statement is incorrect because there no machine that actually performs what we are trying to achieve.
The machines perform somewhat similar operations, but it is not what we want to do.

I want to apologize for some of the reply mistakes. I have done this a long time ago and I'm not knowledgeable of the process. I will try to respond to every point that is raised. Otto Thanks for the input on the mig wire and options. I thought that was the choice, but there is no harm in running by...

In response to Angus. I'm consulting an engineer, but from the initial conversation with him, I'm not sure that he has ever designed anything like this. For the past 36 years I learned how to weld on my own by trial and error MIG ( Millermatic 200) then learned stick around 1995probably some 5 years...

Thanks for the initial reply ( weldin mike 27). The concept is to build a rectangular box that will house the hydraulic cylinders and the cutting assembly ( fixed blade and a moving blade) the actual forces pushing on the ends are projected for around 750 tons with 3 cylinders and we have to leave r...

I'm asking for the help of anyone that has experience in heavy structural welding. I have been welding since 1978, as a hobbyist and I now have to fabricate a large frame for a hydraulic press. The plates are between 1" and 3" thick. The projected working load is around 750 tons. Questions...
