I've noticed that several people have used chain master links in place of clevises,which are obviously plenty strong for the task, but I can't figure out whatseries or type of chain these links are from. I run a 520 series chain onmy enduro motorcycle, which I believe is one of the largest of the motorcyclevarieties but the links that I've seen used in place of clevises are elongated,and most likely not used on a motorcycle drive. Anyone know whey type of chain these links are from, or where I can find some?--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 6 Jan 2010 10:30:59 -0800 (PST)

Mark:The chain is a ANSI #50 roller chain for 3/16" clevis pins and bolts. Youcan get it here ==>http://www.mcmaster.com/#ansi-single-st ... in/=59cxim or here===> http://www.tractorsupply.com/. I wound up using left over chain fromwork and from friends. Just grind of the heads of the link pins and drivethem out, or use a chain breaker.Rick Schreiber> [Original Message]

Great! Thanks Bill and Rick. I know I have seen this in a couple of places, butas usual, when I want to see them, I can't find them. I think I am going to utilize this method.--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Using half of the tail cables?

Well, since my name was mentioned, I guess I have to reply.Actually, I was not referring to the control cables at all, just the bracing cables- and since the attachment points of the rear bracing cables are not in linewith the pivot point (the rear edge of the stabilizer), the lengths of thosecables will also change SLIGHTLY if the front edge of the stab is shimmed upor down.However, since the pivot point of the stab incidence is basically the same as thepivot point of the elevators, there shouldn't be any need to readjust the controlcables.I'm done now.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 06 Jan 2010 19:07:52 -0500
