At the moment i have read in it,s entirety the cyclone guru web site sheeesh, several australian authers and am going to make my own cyclone i have a rather snazzy fully sealed moter from a spray booth although the fan speed is only 1450 rpm the machines i wish to extract dust from are a radial arm saw a dewalt 7740 had this saw since 1980 and it has made me serious money over the years,all without sawdust removal,a habco combination machine my fathers over 50years in age,and groove cutters with which i make windows and joinery details with, I have 2 weeks off to remove a lump of my shoulder (my carrying shoulder so wether that has something to
do with it) so more reading before i start the construction process possibly a good use of the recuperation time.
thanks for your welcome
regards
