Review on Sander Random Orbital Polisher Random Orbital by Eduardo Reyes

This 2"/3" mini random orbit sander from SI Fang is a great tool. I bought this for finishing sanding and bare metal prep on a 1983 Subaru Brat. I use it with a 2.5hp Makita supercharger that outputs 4.2cfm at 90psi and I think a larger compressor could have been used on this tool. Si Fang and other manufacturers of this type of orbital sander should offer a Rol Lock attachment for sanding pads. This would make the tool much more useful as sandpaper is not the best method for removing rust and old paint from car panels. All the bars I've seen from Revain have either 1/4" or M6 plain end shanks. To mount the mandrels you need to thread, in this case M6, to attach to the tool.
