guys:I have a co-worker who's father used to own a Grumman Tiger. He gotalzheimers and had to give up the plane. But they kept the prop as akeepsake and sold the plane. It's a McCauley 1A170 FFA 7563 (I aint gotthe slightest idea what that means) But anyway, I have the prop leaning upagainst the wall in my office. It looks like it's in good shape- metalprop. No major nicks. No cracks or anything that I could see with thenekkid eye.I couldnt confirm one way or the other the story on this prop but I have noreason to think there's any story other than the one I've been told. I toldher I would try to find out how much it's worth. I can then put it on ebayor barnstormers for her.Any ideas?Thanks Bert (who needs a vacation badly)________________________________________________________________________________Date: Mon, 25 Mar 2002 18:41:25 -0800

There is one particular McCauley prop that you had to take off of theGrumman (or keep doing a 100 hour repetitive AD). Many, many Grumman ownershave these props lying around, I have one. It is probably one of those, notmuch use.----- Original Message -----

I'm looking for anyone who is using an 80 hp Franklin to see what woodenprop they chose for their operations.So far I havn't had a goodresponse.I have info on an 85 hp using a 72X43 but not sure if this isgood for my app.Thanks.________________________________

I have a 80 hp Franklin which is now a 75hp because I needed new pistons and couldn't find 7:1 compression replacements. I had to go with 6.3:1 which drops it to 75 hp. It's not in the air yet but I just bought my prop from Tennessee props. They recomended a 72 X 42. Since the engine is similar in displacement to the Continental A65 it makes sence to me that they would be the same..The Franklin puts out 65hp at about the same rpm as the Continental but is 75 or 80 hp at 2500 rpm depending on the compression ratio..Sensenich recomended a 72X43 but their price was out of my budget zone..I decide it would be better to error on the low side than to try to swing too much prop for the engine. The tennessee prop has a fairly wide blade so maybe that's where the difference is between the two recomendations..Like I said I haven't flown it yet but did do my homework..Ed Grentzer>From: harvey.rule(at)bell.ca>Reply-To: pietenpol-list(at)matronics.com>To: pietenpol-list(at)matronics.com>Subject: RE: Pietenpol-List: RE: Prop>Date: Tue, 16 Aug 2005 08:16:40 -0400>>I'm looking for anyone who is using an 80 hp Franklin to see what wooden>prop they chose for their operations.So far I havn't had a good>response.I have info on an 85 hp using a 72X43 but not sure if this is>good for my app.Thanks.>>>________________________________>>From: owner-pietenpol-list-server(at)matronics.com>[mailto:owner-pietenpol-list-server(at)matronics.com] On Behalf Of>Phillips, Jack>Sent: August 16, 2005 8:10 AM>To: pietenpol-list(at)matronics.com>Subject: Pietenpol-List: RE: Prop>>>Chris,>>>I've got a new Sensenich 72 x 40, which is supposed to be a climb prop>for an A65.

Hi Ben..If you're building your control tube to plans useing 1020 or mild steel all is cool..But if your're useing 4130 there is one welding author who says you shouldn't braze 4130 because it can cause it to split..He recomends welding it instead..I learned this after brazing mine with no problems and I've talked to guys who have flying Piets with brazed 4130..But "THEY" say you shouldn't as it can weaken the metal...Ed Grentzer>From: Ben Charvet >Reply-To: pietenpol-list(at)matronics.com>To: pietenpol-list(at)matronics.com>Subject: Pietenpol-List: Torque tube bearings?>Date: Mon, 15 Aug 2005 21:16:31 -0400>>>Hi All,>>I'm in the process of fabricating my control sticks and torque tube.
