So i found a delta drill press for a great price. The only thing, is it was under 5 ft of water during sandy. The seller said the water hit the bottom 2" of the motor but he powered it up 2 days ago and it worked fine. Any downsides to buying this machine?

Take the motor off and completely disassemble it. Flush it well with fresh water and allow it to dry for days. Replace the bearings and if a single phase take a close look at the centrifugal switch. If the contact are corroded at all use either very fine sandpaper or a point file to clean them up. Be careful that you dont over do the filing/sanding. Just enough to make them shiny again. Any surface rust can be taken off with a scothbright pad, the gray one, and some WD40 and elbow grease. Hopefully the water did not get into the spindle assembly. If so, it will also need to come apart and be flushed with water and allowed to dry. Bearing replacement would also be a good idea.

The centrifugal switch is located on the top of the motor so it didn't get wet. I doubt that water could penetrate the bearings and the winding will be fine when they are dry. I think you got a buy.

Salt crystals from almost immediately after being exposed to air. It has been recommended to immerse immediately in fresh water and completely rinse afterwards. Give it a good soaking. If this was not done then I would pass on it. Only if it was free would I even consider a tool that was in salt water. I know of a person who went through Sandy and his expensive shop got flooded. He will most likely have to replace all of the motors and electronics on his tools. Some will go to the recycle because of the cost involved.
