Stainless? Bill Sullivan"Bill, stainless will fatigue and crack like any other metal. To reduce the chances, keep the vibration to a minimum, keep the exposed metal past the anchor point as short and light as possible, in order to make both rules happen, add another brace. In two directions (triangulate) if possible, safety wire works to keep small problems from going through the prop and becoming big ones. add vibration isolaters.When you've done your best, grab it and shake looking for movement then keep an eye on it!Do not archiveBoyd YoungMkiii Utah* ________________________________ Message 3 _____________________________________ Time: 08:23:40 AM PST US From: william sullivan Subject: Re: Kolb-List: Re: My Firestar 2 Build Boyd- My experience with stainless is limited to my silverware drawer!

Unfortunately, everything that falls off the engine on a Kolb goes through the prop. Important to do a thorough preflight each day, and continue to check the engine after landing. I've lost muffler mounts, a football size oil tank for a 582, strobe light, lots of exhaust systems to vibration. Had lots of problems with vibration and early exhaust systems on the 912. Stainless with definitely let you down. Keep an eye on it. Beautiful flying weather at hauck's holler, but Miss P'fer needs some TLC before she will fly again. john h mkIII Titus, Alabama From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of B Young Sent: Sunday, March 24, 2019 9:53 AM Subject: Re: Kolb-List: Re: My Firestar 2 Build _____ "Question- Is there much chance of the muffler mount cracking?
