    Hello, I'm working on a piece of furniture, and according to an FEA study one of the parts (the lower frame) needs a yield strength of roughly 65,000 PSI to pass certain certification tests. There are two versions of the chair, one made from mild steel and the other from stainless steel...

    Question regarding 304 and 301 stainless

    Hello, I'm working on a lounge chair design, and the client wants to use stainless steel for the frame elements, as they like the appearance. However, they also want the elements very thin (again for appearance). My question relates to spring tempering 301 or 304 stainless barstock. The...

    Wire Form Battery Contacts

    Hello, On a current project, I need contacts for the AAA battery compartment. I can use Keystone 5214 and such (stamped spring steel, with a spring on it) but I'd rather use case mounted contacts that were a simple wireform - you can see these in most remote controls. Only I'm having a...

    Small, inexpensive 6 pin connector needed

    Converting Surfaces to Solids

    I'm working on a project where there's an ID person using Alias, a surface modeler. As the design has grown in complexity, I don't seem to be able to use her surfaces to crate a solid body.

    Alternative to Unfrag or Eco

    I've read some concerns here over Unfrag or ecosqueeze, and thought I'd mention an alternative. In addition, this alternative can fix corruption problems. For instance, I had some corruption that prevented the circular pattern feature from working correctly, but using this procedure fixed that...

    Releasing Part Files To Clients

    Here's a question that came up recently. I'm an independent consultant/designer. Recently one of clients asked if he could have the actual part files from my CAD program, in addition to the IGES and STL files I planned on giving him. My general instinct is no not deliver the part files, as this...
