A small machine shop, is located on the Mesa and provides services to all Mesa users. The shop machinery includes an NCC vertical mill, a lathe, a drill press, a band saw, and several other metal working tools. The primary purpose of the shop is to provide quick turn-around fixture fabrication and modification in support of all Mesa users. A professional machinist from the Mechanical Fabrication and Test Section 357 can be provided to operate the shop equipment. To get a machinists support the user can submit service request using the NBS web page or by contacting a fabrication services representative in Section 357. The user's request is acted upon by a cognizant Manufacturing Engineer (ME) who then provides a cost estimate and creates the appropriate Traveler authorizing the Mesa machinist to proceed with the work. The user's project is then charged the appropriate number of Mesa units to cover the work.

If an individual user wishes to use the shop equipment each applicant is required to take a series of basic safety classes offered by JPL safety. Upon completion that certification is mailed to the Mesa staff and then that individual is checked out on each tool that he or she will be using. Their name is then added to the list posted in the shop.
