This has been a brutal time for those of us that manufacture and deliver our own products. Materials and shipping went through the roof so we stopped making boxes all together. We tried our best to bring back manufactured products but it wasn't profitable in the context of our new inflated economy.
I could easily make better money stuffing tacos at Taco Bell or flipping burgers at McDonalds. I have decided to drop making chuckboxes and do some things with my woodworking website. and maybe a couple of other ventues too. See my personal Youtube channel for more on that.
Also, you can still get any product we have designed over the years by making it yourself from our plans book. ( Or maybe you can work out something with a woodworking buddie that also needs a chuck box????)
