New here. Only tumbled once about 5 years ago in a small Thumler's, but bought a big one and wanted to know what modifications will help me get the most satisfaction out of this tumbler?
Replace lid liner with HDPE or similar? Rubber or board under the base?
Thanks in advance!

The lid gasket is really the only weak spot. I always stocked gaskets when I sold them.

I can usually get 3 or 4 loads from start to finish out of a lid gasket. Got a load in 60/90 right now, and this is the 5th load on this one. I'll probably change the gasket when I got to 220, just to be on the safe side.
I have mine sitting on a carpet scrap, backing side up. Does a pretty good job of deadening the noise.

Replace it with HDPE. You'll never have to replace it again. The stuff is sold in 12" x 12" cuts with a jig saw. Put the lid on it, draw around, cut, drill a few holes. You won't have to buy gaskets or play shipping again.

The gaskets that Thumler's sells are made of a "live" rubber so replacing them with another (harder) type of rubber may in fact show faster wear.
I don't know the right nomenclature for "live" rubber but will try to explain what I mean by it.
If you had a 4" thick block of "live" rubber and bounced a round rock off of it,the ball would bounce much further then it would if you bounced it off of a block of harder rubber. So even if the gasket was made from harder rubber it(the gasket) may wear out faster???
The word I "may" be looking for when trying to explain "live' rubber may be elasticity?
"Gum" rubber is very soft and will bounce like the old Super Balls did.I believe the Thumler's gaskets contain some of this "gum" rubber in their composition?

You can get HDPE from amazon.com - comes up first thing in a search for "HDPE sheet". Not sure what thickness you're looking to replace.

I picked up a 1/8 x 12 x 12 at Grainger, it was less than 8 dollars. All ready paid for it's self many times over by not buying gaskets and shipping. To shape and drill anything that cuts wood cuts this stuff.

I found a truck tire inner tube and cut new lid liners out of it. I tried vinyl hall runner, but it wore out pretty quickly (just as Connrock stated).
