Hi John, I see where Brownells has 1095 annealled, you might have to use this and get it professionally tempered.... The problem is getting 1075, or any other "annealed" spring steel! It is dead soft and easy to form and cut, it also has a grain you need to pay attention to, it runs linear with the sheet or coil... Then, when you have the final part shape, you have it heat treated, and then drawn back to the correct strength for the intended spring... The small quantity spring steel most often offered is unfortunatly, already tempered!! Soooo, to get what you need, you usually have to buy a minimum quantity coil of so many pounds and it cost several hundred dollars to start with... Making the springs is the easy part...finding the "annealed" spring steel in the exact thickness needed, is the hard part!!.... Has to be annealed to work with... and no, you can't anneal and retemper... too much work to get correct, if possible at all... I will certainly assist you if i can John... best to you, til....lat'r....GT

BTW John, you can compare compression by clamping one end of the flat spring to a flat surface and pressing down on the apex of the bend to a preset stop, with the whole works on a scale... do the same with your test samples, when you get then made, and the pounds of force needed should be close and comparable.....
