"How do you keep it cool".....
The same way we keep a cpl other pcs cool,notably a 453Z Grizz planer.....we use a QD air hose fitting with a pce of 1/4" copper refridge line soldered in it.This gets bolted to the outer case.....refrige line easily bends to exact shape/angle to direct air "at" offending part.
Staying with RT.....it helps with general airflow from a dust management standpoint.You have to play with the "balance" of air,which is really why this works so well even beside the VERY noticeable cooling effect.But get the balance right(adj air pressure),along with air/tube angle, and it'll really clean up the DC.
There are these cheapy brass air regulators that are quite slim.Might even be HF brand?Totally useless for anything important(air wise),but they work fine for regulating stuff like RT's.It's just a pce of hex barstock with a thumbwheel calibrated in some little hieroglyphics?And they leak a bit....don't care.Set it,forget it,disconnect shop air hose when not in use.
Those who say it cannot be done shouldn't interrupt the people doing it.
