Capen" Subject: RV-List: Vernatherm stuck open? Folks, I think my Vernatherm is stuck in the open position allowing oil to always flow through the oil cooler. Here's the basis for my thinking: In October during some of my flights, I was seeing OAT's of 35 and 40 with corresponding OilT's of 174 and 179. In November during one flight I had OAT of 62 and OilT of 177 - I stopped and had lunch - during the flight home, I had OAT of 65 and OilT of 146. Yes plenty of time for it to have warmed up...and no, I didn't change anything on the airplane during lunch. All flights after that one have had OAT's in the 50's and 60's with OilT's not breaking 140. Your thoughts please... How do I unstick the Vernatherm? Is it possible that during lunch that day, my rings seated and my engine finished its break-in process? Thanks, Ralph RV6A N822AR @ N06 46.3 hrs - happy with the CHT's, found something else buggin' me ________________________________ Message 2 _____________________________________ Time: 08:56:04 AM PST US From: Kelly McMullen Subject: Re: RV-List: Vernatherm stuck open? The Vernatherm doesn't work that way. It has an expanding salt/wax inside and expands with temperature until it closes the bypass opening. There are published dimensions, so you can remove the vernatherm, measure its length and see whether it is at the expanded dimension or cold dimension. You also could just create a cover for your oil cooler with say 50% as big an opening as the cooler itself, and see if it makes a difference, watching to see oil doesn't get too hot. Ralph E.

Rick ________________________________ ________________________________ Message 4 _____________________________________ Time: 02:41:03 PM PST US Subject: RV-List: Wing Cart From: Ian In addition to what David Nelson said about a wing cart: - Make sure your castering wheels are well attached to a robust structure. Mine were always falling off/breaking the wood because there is a lot of force acting through them. - I used ex-furniture casters which worked fine in the garage, but not on the more uneven driveway. - Make one end the shape of the wing rib and the other end flat, to support the main spar as it exits the wing. - Decide how you want the wings facing before you cut the shapes. Least space would be lower surfaces facing each other, but facing outwards lets you work through the access panels in the wings. - You don't actually need an outer frame if you use a relatively strong spine, like a 2X4 attached to a 2X6 but make it shorter than the distance from the landing lights to the inner wing. - I found foam strips, stapled in place around the curvature of the wing slot helped protect the wings.

Read about it at their website... http://www.soundoffsignal.com/warnamber/flashers/Headlight/ETHFSS-SP.htm You can buy one for about $40 online... http://ledguy.net/store/index.php?main_page=product_info&products_id=106 I have recently installed a $60.00 HID kit (2 bulbs & 2 power packs) I got on eBay (search for seller FLASHPLUS - no business affiliation!) and have been flashing the HIDs with the above wig-wag unit with great success. -------- Tony Kirk RV-6A N57TK www.TomsRV8.com webmaster www.EAA582.org Read this topic online here: http://forums.matronics.com/viewtopic.php?p=275651#275651 Attachments: http://forums.matronics.com//files/n57tk_wigwag_hid_204.wmv ________________________________ Message 6 _____________________________________ Time: 05:30:36 PM PST US From: Jason Edwards Subject: Re: RV-List: Flop Tubes 4-Sale Jerry, I would like a picture of your flop tubes, I am interested.

I've since order the updated parts and modified mine and I believe the axle is a AN6 bolt not a AN5 but my plans are at the hanger. Always great to hear from Das Fed :>), but I already checked this and the leading edge tank to fuselage bolt is a AN4 so "NO JOY" here. Great ideas of things to check, I'm still trying to sort this out. Perhaps a call to Van's is in order.
