    Flanged lighting holes

    I am brand new to SW and I can barely get it around the patch. I have a friend that is halfway decent with it and he is giving me some dual but, I must admit it is a struggle. Any way, does anybody out there know a way to make flanged lighting holes for a spar shear web? I can make a hole alright but it sure would be nice to put a flange on it. Anyone???Buehler....Buehler....

    Do you mean making flanged holes in your SW digital model, or actually making flanges?

    The easiest way, if you have a number of different parts that need this feature, would be to use a forming tool. The part would have to be a sheet metal part and you would have to create the forming tool (or tools if there is more than one size). Another way would be to use a Revolved Boss which would not require the part to be a sheet metal part but you will need to determine how big to make the hole because the flange will be inside the original hole when you're done.

    Below is a Swept Boss used to create a bead. The Revolved Boss works essentially the same way.

    I cut the hole first and this hole is the outline of the bead with the radii.

    This is the profile of the feature.

    Whoa up here boys...I'm not much of a blogger or social media kind of guy so maybe I made a mistake. I posted this under SolidWorks forum I thought. SW short for SolidWorks. I am glad to see all of the quick responses though. As for making flanged holes in sheet metal, that's pretty easy. I think I made my first one about 35 years ago. Designing them in SW is another story. That requires a skill set I am struggling to master. Kinda like flying a taildragger for the first time, only much worse. So I have been able to draw my spar flange and I need to put a 1/4 inch flange on the 3 inch lightning holes I have in my SW sketch. How does one do this? A step by step procedure would be good for me. And by the way, on making holes with flanges on them in the real world, do yourself a favor. Buy a flanging hole punch. You will be glad you did.

    Here's the equivalent of a flanging hole punch in SWx;

    This is the punch (forming tool). It makes the hole and flages it in one step.

    Applying the tool to the metal.

    Yes, there are some rules and methods to making the tools but once you do it a couple of times it will become easy. It's all in the help documents. Good luck.........
