Rotating stand and sawhorse Rotatable wood stand and sawhorse Figure 3-14.  Rotating stands and sawhorses facilitate easy access to top and bottom surfaces during the fabric covering process.  Figure 3-15.  Some components of a work area for covering an aircraft with fabric. Rotating work stands for the fuselage and wings provide  easy, alternating access to the upper and lower surfaces  while the job is in progress.  [Figure 3-14]  They can be  used with sawhorses or sawhorses can be used alone to  support the aircraft structure while working. A workbench  or table, as well as a rolling cart and storage cabinet, are also  recommended.  Figure 3-15  shows a well conceived fabric  covering workshop. A paint spray booth for sprayed-on  coatings and space to store components awaiting work is  also recommended.  Many of the substances used in most re-covering processes  are highly toxic. Proper protection must be used to avoid  serious short- and long-term adverse health effects. Eye  protection, a proper respirator, and skin protection are  vital. As mentioned in the beginning of this chapter, nitrate  dope is very flammable. Proper ventilation and a rated fire  extinguisher should be on hand when working with this and  other covering process materials. Grounding of work to  prevent static electricity build-up may be required. All fabric  re-covering processes also involve multiple coats of various  products that are sprayed onto the fabric surface. Use of a  high-volume, low-pressure (HVLP) sprayer is recommended.  Good ventilation is needed for all of the processes.
