With Canyon Diablo, the numbers just don't pan out to retool for PPD with the reduced vertical height as I will be wasting a lot of metal for sheets A and B. Don't forget about the very high costs of getting all that brass in 11.5x35in long sheets over to the US.
It does make sense to retool for my US etcher as I have a known commodity and the 18 x 24 is more favorable just shift items around from sheets 1 and 2 to sheet 4. The idea would be that the the 1/2 sheet of 4 would absorb parts not fitting after I retool from 18x30 to 18x24. The stainless sheet would not need to be retooled, just re-ordered.
At least that is the intent if anyone actually orders one. If not, I will have the only one as part of my collection. So let's see if this time is different. No one ponyed-up 10 years ago at half the price, so I have my doubts. Hope to be proven wrong.
