Spin Coater System (Original Design)

This was my attempt to build a low cost spin-coater system.  For about $70.00 dollars in parts and some ingenuity (and ofcourse access to the college's machine shop), I was able to put together the system shown below.  Ironically, we latter purchased a commercial spin-coater for $5000.00, but I saw little difference in the sample prepared using the one I built.  In my opinion, the only reason to buy one of those things is to get better control of the overall spinning process which is needed by some applications.  However, most people just need something that goes around fast, and holds a small sample for R&D work.
