* Hot metals: blast cabinet and plasma cutter
* Lasers: all of them
* Tormach milling machine
* Spray booth
* Cooling air at the shopbot
Our current compressor stage has suffered an intermittent mechanical or electrical failure that has proven difficult to diagnose, even by Zorn, the compressor company we called for help. Additionally, Zorn has had great difficulty sourcing replacement parts for our 45-year-old compressor, and Quincy, the manufacturer, has been non-responsive to our requests for service and parts.

The service technician noted numerous safety-related concerns about our compressor, including:
* The cushion chamber is no longer legally able to be manufactured due to an explosion hazard; it was a common feature on older compressors.
* The drive belt is beyond end-of-life.
* There is no belt guard present.
* The gaskets used to attach the compressor stage to the tank are improper.
* The safety pressure release valve is not directly attached to the tank, reducing its effectiveness.
The compressor stage head gasket has a history of leaking badly due to over-torquing the head bolts, causing the head to warp. The compressor requires regular replenishment of oil, placing a timely and unnecessary burden on operations team members and increasing running costs.
