**Update** I have gotten a lot of really dumb comments and some extremely arrogant "you should do it this way" comments. I ran this job the way I did because the plate had a slight warp to it. clamping it directly to the table may have pulled some of it out, but not all and created more sealing problems in the long run. s

I have done a lot of plate milling in my time, but usually I do it on the Lucas Horizontal Boring Mill. This plate is small enough to fit on the Metal Planer Mill.

This machine started out life as an American Tool Works 8 Foot Planer, but was stripped of its planer drive by the previous owner and modified into a large drilling machine. When I bought it from the auction, it was just the planer body and the DC drive they had put on it. I installed the Bridgeport head and DRO to make this one of the most profitable machines in the shop.

This job comes from a local power plant that takes waste products such as food waste and byproducts of food manufacturing. They put it in large vats and start the fermentation process. The Methane gas produced is then used to power 4 large Caterpillar gensets. The waste products from the fermentation tanks is then used as fertilizer. This is a totally green energy system, and it is right here in Northern Wisconsin.

The plate chiller is used to collect heat off the generators for heating the facility. During a cleaning process, a final flush was missed and the acid etched into the plate rendering it useless. I will attempt to clean it up the best I can and see if we can save it.
