5/16" makes the tool too wide :) I have to keep it as small as possible. Pict. show how an example how it is stored during the dive.
That's why I even trimed the 8mm allen Key :)
But I did a test to one of my tools and trimed of 2 mm to get to the thicker section 1.6mm compared to the...
Till now I used s17-4PH A900 but as said, the flat driver bends with excessive torque. Thickening it might be enough. I'm not sure the current manufacturer is using S420 2.0 material and therefore I asked. If he don't I'll have to decide whether to continue with S17-4HP or look for another...
Is lost wax better in that issue?
As for now, I had no other problems with the tools and I hope to solve it with the new better design and with S420 2,0.
Thanks Ed for the advice. The way it is designed is with thoughts of how it is used. Having the flat in the middle wouldn't work as it touches something.
Every mm is with usage thinking.
The tools is not always rinsed as it sits in a case or pouch. That is not my concern as it will is treated with ArmorGalv process.
As for bending vs. breaking is more of my concern. Today it bends when using excessive torque and I have thickened it from 1.8mm to 2.2 and widened it from 4.6 to...
Hi, I have designed and produced (outsourcing)a tool for diving.
Till now we have made it from lost wax molded SS17400PH hardened to HRC42.
A new manufacturer suggested me to use MIM and S420 2.0 with a hardness of HRC46-54.
There is a flat driver on this tool that is bending when using lots of...
