FYI, I have enough material for 5 more sets up for grabs now, when I reorder, I plan on switching to 70/30 Cuni which has 20% more Nickel than the 90/10 I am currently using.
As far as I can tell from research and phone calls, it should not affect heat up times much but the material is harder/tougher.
Just a heads up so you can make a better choice. I think the price is going to remain the same but I will know after I try and work with it. Edit, the backing plates or press couplers will still be 90/10 material. Just the main pressing block will be 70/30.
I have only worked with 70/30 a few years back in small tube material and it looks like stainless but it was much harder to work with, than 90/10 Cuni.
One more note, the shop changes in progress have brought me a nice milling machine with table feed and the especially the much needed tooling , for a nice super flat finish. I got it dialed in yesterday,
It's used and old, but It's titties!
