Press Experts...Please Advise

I've been put in charge of setting up two presses at work. One of them will be used to perforate tubing and one of them will be used to form/punch muffler endcaps. After years of disappointing suppliers we have decided to do it ourselves. I have some general questions about presses that I am hoping you guys can enlighten me.

1. I've narrowed my choices down to Minster, Bliss, and Komatsu. I was thinking the Bliss and Minster because they are readily available and the Komatsu because of its reliability. Are these machines reliable and durable? What models should I be looking for? I am looking for 35 tons or more on the perforating machine, die set requires 11 tons at a time according to a quick calculation.

2. What type of support equipment will be needed? I spoke with someone who was in maintenence at a press and die shop and he mentioned these presses consume a lot of compressed air. Is this true and are there any other surprises that you guys can thing of like this.

Thanks,
AJ

you are going to have to buy fairly new models to comply with osha. Old presses are cheap but you run into safety problems.
