I just purchased a Leecraft ZCI for my new(used, but new to me) TS3650. I noticed the Leecraft does not have a countersunk screw hole to secure it to the table like the OEM insert does. Even though the Leecraft has front and side adjustment screws that allow it fit snug, I'm concerned that it may not be secured enough. Is there any need to drill my own hole for the screw? Or does anyone have any experience with this either way? I appreciate any feedback. Thanks.
