Finally i received my CNC machine chassis. need to find some time to start mounting and using it.
great finish and solid construction.
before i start working on the head, i like to get some aire velocity readings to find high speed spots and also death or low spots. the highest reading was around 310 fps, which is far from k20 readings. k20 mas around 387 fps some spots.
Another way to find death spots. this is a flow ball. this method consists in disturb the air in the spots you consider to see if CFM reads higher or not.
i managed to obtain a gain of 34CFM. not bad for the first day
