Subject: Pietenpol-List: Piano hingesGene,I accumulated a pile of hinges (at great wasted expense) before I got one I liked. I went with the extruded type, aluminum. I got a "special quote" from Mcmaster Carr, because 6 ft. was the longest length listed in their catalog for that type. They got back to me and I bought two of them 7ft. long. I see in their catalog that now the standard lengths for some types they offer are 8ft. I love paging through their catalog.

OK, the McMaster Carr is a great source, I had not thought of them, but I also love their catalog. Sooooo, now the question becomes what type and thickness are most of you using?? I am thinking the .050 thick aluminum hinge with the 1/8" pin and 3" width (based on the advice about the mounting holes. Does this sound like what others have done??Gene ----- Original Message -----

I think it's a bad idea. I have been around a lot of good quality grade 8's. andfrom what experience I have had. they are extremely strong.but extremely brittle.Ihave welded them at the head to such things as electric motor bracketsto keep them from turning and they would almost immediately break beside the weld.i know that is a different use but just to show how they react. also seenthem installed as shear bolts in the drive shaft of a brush hog. once again thebroke right quick where grade 5 were elastic enough they might go for days.neither a good reason to know for sure whether they will hold up on a prop,butI think for my money I would much rather run grade 5 than grade 8 unless theload was specifically in tension. not in shear.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.php?p 5843#205843________________________________________________________________________________Subject: RE: Pietenpol-List: Piano hingesDate: Tue, 23 Sep 2008 19:52:53 -0500
