Subject: Pietenpol-List: PulleysWhich pulleys did you guys use on your torque tube? Is it best to use ball bearing type pulleys wherever possible? I noticed that the ball bearing 2" pulleys are .484" or more wide, 2 of those together is wider than the torque tube. The cheaper 2" phenolic pulleys with the bronze bushings that are specified as usable with 1/8" cable are also too wide at .438". (Am referencingpage 140 in the new AS catalog).Also read the archive discussion about the front torque tube elevator pully needing to be bigger than 2" based on 43.13 and what Bingelis says in his book (using 1/8" cable). Would their be any problem using a 3" ball bearing pulley there?ThanksRick Holland________________________________________________________________________________

I used the 2" ball bearing pulleys and yes 2 of them are wider then the torquetube so I put a jog in the pulley holding-on-tab thingies to make the gap 1".I also extended the tab down around the tube to get a little more weld area.Some people don't like the 2" up front but it seems to work. I used the 2".Chris TracySacramento, CA ----- Original Message -----

I assume you wiggle them in at an angle through the bracket first then put the whole assembly into the holes in the spar.like a chinese puzzle.DJ Veghveghdesign.comMesa, AZ 602.743.5768"Where there's a will there's a Vegh"- ----- Original Message -----

Very pretty work,only thing that would bother me is there is not really a braceto carry the side load as the cable pulls on them the way I see that.-I realizethere isn't a great deal ,but the pull would be at about a 45 degree angledown the length of the spar would it not? the drawings I have for the GN-1 havethe bracket built with 2 bolts and the strength runing parallel to the spar-horizontal.Iknow they need to lean some to align with the horn end but I wouldbe concerned if I didn't add some type of brace there.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I'm sure these types of brackets haveperformed satisfactorily in the air for many years and hours. In this application, there is not a lot of side load to speak of, because you can onlytighten the aileron cables so much before everything binds up. Dan HelsperPoplar Grove, IL.

Well if it's not broke don't fix it I guess-thanks for the heads up.as you cantell I have not seen a set of original Piet plans and I have no doubt if theyhave been built for that long they have proved themselves.I had no intention ofstepping on anyones toes-just would rather be wrong than see anybody hurt.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 21 Mar 2007 17:27:16 -0700 (PDT)

Hello Everyone, I read this forum everyday and it keeps me motivated in movingforward on building my piet. I am looking at getting the pulleys for the aileroncables. The plans call for 2 inch formica pulleys and 3/32 cable. I am lookingat ordering the pulleys from aircraft spruce part # A-123 (nas) it doesn'tshow any hub dia. or load limit (lbs). I was wondering if anyone could tell meif these pulleys are ok or have any other suggestions? Thanks Larry VRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Larry The A-123 series pulleys are used on secondary controls because the pulleyhas a plain bore. The MS24566 series are used on primary controls becausethey have a sealed ball bearing hub. I am using the MS24566-3B pulleysbecause I quite frankly didn't realize the aileron control cables were only3/32nd. If I would have known this I might have gone with the -2B andmodified the fitting. As it is I will just watch and see if it's a problemfor the 3/32 cable but I don't think it will be a problem. ChrisSacramento, CaWestcoastpiet.com-----Original Message-----
