Esslinger makes what is called a HD block but a $2500 buy in Plus all machining.

Once filled with hard block this will be pretty strong. My current one is not filled and .030 over. This one I’ll fill to 2”of the deck and will only be .020 over. The last one went 5 years so if I get that again I’m more than thrilled. I’m pretty easy on my stuff so I’ll be ok.
