From my model airplane days you would tighten it once, wait a while and tighten it again. Has something to do with the way wood crushes... Anyway that's my two cnets worth.

The maker should tell you or placard the prop itself as to the required torque. If you can't find this out, make sure you use a full size crush plate and use the standard torques for bolts out of AC-41. Determine first if you have the 3/8" or 7/16" bolts. Make sure you use the right nuts too.

Each year, I back it off and re-torque it. Any more than that, you can see the "Crush Plate" crushing into the prop. When using 3/8 bolts, the torque was around 15 to 18 foot pounds. I just got off the phone with Sensenich. They recommend a torque value of 175-225 inch pounds (OR 15-18 foot pounds) for 3/8 bolts. If you are using 7/16 bolts, you use 225-275 inch/lbs.. The important thing here is like Jim said.... Feel it and watch what the plate is doing to the prop when you tighten. If you get too carried away (and it's easy to do) you can squish the wood fibers of the prop. I think Graham also wants to know the torque value on the Extension to Crank. There are two different values depending on the diameter of the bolts. Seems like it was in the neighborhood of 40 - 45 ft/lbs.

I increase the torque value in 5 lb increments to insure that they are equal. To track the prop measure from the aft end of the boot cowl to the tip of the prop, rotate the engine 180 deg. and measure the other blade. The measurements should be within about 1/16" of each other. ===== BRIAN ALLEY (N320WT) How are you going to win by a nose if you don't stick out your neck? __________________________________ http://sitebuilder.yahoo.com ________________________________ Message 11 ____________________________________ Time: 01:26:30 PM PST US From: "Mike Pierzina" Subject: Tailwind-List: I check for posts daily RCVD_FAKE_HELO_DOTCOM --> Tailwind-List message posted by: "Mike Pierzina" Hey Guys, I'm still finishing my Kolb Firestar(90% done,90% to go.

I have discovered that the expensive degreasers and wax removers are little more than dilute acetone and or MEK (methyl ethyl ketone) both available in WalMarts (paint section). I even had found some NOS mint position lights for $2.00 but they were clear---investigated glass actual 'staining' and found that the process was easy--but the glass had to be CLEANED. Turns out it was acetone with a bit of distilled water ( the bit of water gives some 'sink' for some of the types of debris, vs pure acetone. Hope this helps.
