I've had my present lathe since 2000 but never thought till now to post a safety tip I've had on it since then. Before I bought my oneway I always had variable speed lathes but they were the old fashioned expanding pulley systems. Next to impossible to accidently brush or knock the speed control lever and have the lathe go wildly out of control... But the (at that time) new VFDs had a very touchy dial that easily spun with the lightest of tough. Right away I thought I know I'm gonna draw my hand across that one day and the lathe is going to go from dead slow to wood shatteringly fast in an instant. So as you can see the simple solution was to find a cheap plastic D pull and screw it on over the dial preventing (most) accidental knocks but still allowing good quick access to the dial.
