Its no more scarier than someone learning to use a table say. As with all machinery, following the guide book and making sure guards are in place etc, not using it if you are tired or having consuming alcohol, these machines are safe. I also said to practice on smaller bits of timber and panels which is good advice for a beginner. If radial arm saws are as dangerous as a few people on this forum make out, the HSE would have banned them a long time ago. The modification that Dewalt made to their latest KN machines, in that they cant be used for ripping or used as a spindle moulder is ok with me. I dont use mine for that anyway and its not because they are unsafe, its because it takes a long time to set up for that and I have alternative means of carrying out the operations.
