Hi W wingnutgabber , whereabouts in Oregon? If close to SE Portland, we could probably help you with the straightening.
1:15 is a very weak solution, and I think Stacy mentioned it only because there are some folks who go that weak. I can't remember exactly what my solution is because I've added to it numerous times over the years (both water and acid) but I'd guess it's somewhere close to 1:3-1:5.
How long will depend on the concentration (higher acid = shorter time) and the temperature of the solution/room. In the summer I usually start with one 5-10 minute etch, and then adjust from there. In the winter when the shop is colder, the time can be as high as 45-60 minute etch cycles. I prefer to do multiple (4-5) etching cycles to get the topography I want.
I am about an hour from you. Thanks for the offer. I will try to work it out myself first.
