I am trying to reverse engineer Abloy PL350 padlock shackle and I run out of ideas how to make it perfect. I know the dimensions of the shackle and I can measure anything from existing one with caliper, but I don’t know how to make the arc for the sweep tool symmetrical. I’ve already tried to import image of it and model the arc from that with spline tool. I’ve also tried to use document scanner instead of iphone to produce better image, but both methods are inaccurate in my opinion. At very least it would be nice to get one half of it in exact measures so I could mirror the other half then, since trying to get both halves of it symmetrical with spline tool is mission impossible if you are not able to use “Snap to” options.
The tolerances are going to be very tight around the shackle so closer the better. There is going to be lid over the whole lock body to protect it from cutting. And the whole design is going to be cut to its shape with laser so getting measures right in the first place will be big plus since the material will be chosen to be as cut resistant as possible.
Just to let you guys know that a thief broke into my warehouse lately and now the door is going to be over engineered as fuck. So next time its easier to blow up a hole in the wall than using the door without a key I am not a engineer (yet), but I find these kind of things interesting as a hobbyist. And even though my insurance covered all the losses I like to give my best to the next thief who tries to steal my property
