Duck, nice pic post and roll your own insert.

Almost 30 years ago I was at a Woodworking show, predecessor to "Thee Woodworking Shows", up in Columbus, and they had a Betterly tools booth. Back then my TS was a PM 66, and I became the owner of a "Tru Cut" insert for it. Since Betterly tools have been in my shop and currently I have one in my General 350.

They offer the option of selling you insert blanks, or you can easily roll your own. They require a slight angle, and 1/4" hardboard, or MDF, Ply can be used.

They also allow for use of the guard that comes with the saw, pretty slick. For the smallish amount of $$$ they cost I let them do the heavy lifting, the aluminum frame is a perfect fit, plus they have a leveling system that is much better than any saw manufacturers.

Similar to the miter saw setup Larry showed they have sets that fit currently just the Kapex. But there I find the cheaper FasCap tapes get me a ZCI opening that works well for the rough cuts I do on my chopper.
