Lauren Child Posted March 28, 2015 Share Posted March 28, 2015 Any ideas what caused this? I was handling it and it suddenly went "pop" and a crystalline part shot out. I'd used some superglue and I'm wondering if it was a chemical reaction or some kind of stress fracture. Given the age I'd have thought if it was a casting problem it would have gone by now.

0 Sean N Posted March 28, 2015 Share Posted March 28, 2015 What shot out, Lauren? Are we looking at the damage to the edge, or the hole that looks like a countersunk screw hole? Could the casting have had some impact damage at some point and have a stress crack in it? Quote Link to comment Share on other sites More sharing options...
0 Lauren Child Posted March 28, 2015 Author Share Posted March 28, 2015 Its the bit at the edge, sorry the phot isn't clear. It may have had a stress fracture, it was in a bunch of bits I got from the auction last week. Quote Link to comment Share on other sites More sharing options...
0 Sean N Posted March 28, 2015 Share Posted March 28, 2015 You probably know cast is prone to stress raisers if it's hit. Looks similar to a brake drum that someone's thumped with a hammer to remove. My guess would be that it's had a bash at some time and you just found it. Quote Link to comment Share on other sites More sharing options...
0 Lauren Child Posted March 28, 2015 Author Share Posted March 28, 2015 Thanks, at least I know its not some chemical reaction that I need to be wary of. Quote Link to comment Share on other sites More sharing options...
