Hi: I'm a Tool & Die maker for 30yrs. And no way I would trust to use an ejector pin for a wing rod. They may not bend until it's to late then they will snap. The reason for this is that they are heat treated. This means that they are hard but some what brittle. In the past I have found a material that makes a good wing rod.The material will bend at extreme loads, but most likly spring back to the correct shape again when the presure is off. And if not your wing is probley broke. I have given this material to friends that had trouble with their rods and they were very pleased and never had a bent rod again. But I must tell you this stuff is expensive. The material is called VICOUNT 44 and has a rc of 44 but is not heat treated but very tough. Usualy has to be specialy order from a place that handles tool steel. The size can come in any size and yes I even ordered it in metric sizes,and usualy come in 36" lengths which I cut by dremel. This VICOUNT 44 material i can't supply and the only source I know of is ASSOCIATED STEEL in York Pa.. SO basicly you'll have to find a source closer to where you live if intrested. Bottom line is try to stay away from ejector pins because they WILL break. Not if! But when!
