I don't remember who it was. Any one recall? If so, how did the experiment work out?

Plexiglass (acrylic) is not that strong. Seems to me it would easily crack tightening the lid down. If going wit plastic I would go with Lexan (polycarbonate) instead, which is vastly stronger. Or better yet, just go with round steel plate. I just bought some off Ebay for a large tumbler barrel I am working on. You can use the rubber gasket as a template to mark where to drill the holes.

I bought these Mark and got a lot more mileage out of them. Pretty sure the same vendor sells the "belts" as well.

I made my replacements out of 1/4" UHMW plastic, I think available at Tap Plastics, likely will outlive me.

WOW a blast from the past! Yea I did some plexi lids like 100 years ago. It worked ok (the plexi hazed up after about a week, wore out in about 6 months, always leaked no matter what I tried. Honestly what I do now is cut a plexi disk a little smaller than the original lid (I use 1/8" plexi as I got a couple sheets worth for free), then glue it to the lid (harbor freight crazy glue and baking soda as a catalyst). Even in 60/90 grit I get several years worth. Once it wears out I glue a slightly smaller disk in. I usually get 3 disk glued in before I toss the lid (could probably do more if I wanted to). The trick is to glue it down, then add a bead of crazy glue around the edge, then sprinkle baking soda on it. The glue and baking soda react (and get hot and give off bad fumes so use proper precautions and ventilation) and form a very durable material. My oldest "repaired" lid is still running after 15 years (probably on it's last leg). I use the same trick on the white AR12 lids (they wear out much faster, and are a bit pricey) Those are running about 7 or 8 years at this point and have 1/4 inch plexi on them.
