Replaced faulty wing strobe light |
|
Spent a few hours trying to figure out why my right wing strobe light was flashing intermittently. It would only flash once and every several seconds with no apparent pattern. It should have double-flashed in synch with the left wing. I switch wires on the power pack and got the same behavior. Then I switched the left and right bulbs. That revealed the bulb was the culprit. Scoured the internet to find a replacement. I purchased my LED navigation and strobe light kit many years ago from CreativAir and apparently they no longer are in business. After identifying the bulb as a Nova Hide-A-Flash (HAFC ) clear bulb with Amp connecter, I found several sources with prices all over the place. Stumbled on to Strobes-n-more's website located adjacent to an airport in Rhode Island. They had the lowest price I could find. Around $31 with shipping. Installed the new bulb and everything works great!

Had to degrease my flap motor |
|
After 89 tach hours, my flap motor succumbed to the well documented grease problem that has plagued many RV'ers. At least, I expect that is the problem. Ironically, I had just signed off on the annual condition inspection. I cannot image that is anything but coincidence. I was on the ground thankfully when I discovered the issue. I was retracting my flaps while and there was no response when I pushed the switch up (or down). The next day, I tried again and the flaps went up but when I tried to put them down, the switch did nothing. I put a little pressure on one of the flaps as I pushed the switch down and the flaps extended. And went back up when I tried to retracted them. The next day, they worked without a problem. I tried them several different times that day and they worked fine. Geez! I decided not to ignore the problem and did some research on VansAirforce.net and found the Vans SB regarding the flaky flap issue. I removed the flap from the airplane and disassembled. I found a lot of grease in the motor. It had worked half way through the housing but had not yet gotten to the brushes. I cleaned it up nicely, reassembled and reinstalled. It seems to work fine. We shall see. The hex tool required is a 7/64th. I used laquer thinner sparingly and some q-tips to clean out the grease. I used strands of wire to hold the brushes back while reinstalling the brush horseshoe back onto the armature. Here is the link to Vans SB about the Flaky Flap Motor. Google Pittman 9234S004-R1 Lo-Cog 12VDC motor to find the motor and data sheet.

Added air dam to number one cylinder |
|
I had removed the previously riveted air dams from in front of numbers one and two cylinders as they were causing high temps. Number one is coolest by about 20 degrees so I recently added some foil tape and tested. The final amount added resulted in cylinder one matching two and three, with number four now coolest by about six degrees. I made an air dam out of some .040 and attached it to the baffling using three of the rivets holes that existed in the horizontal flange that supports the ramp. I will have to fly again to see if this air dam has the same effect as the foil of the same profile.

Installed upper and lower main gear intersection fairings |
|
Installed the RVBits upper and lower main gear intersection fairings. The lower ones were easy to locate and drill. The upper one fit nicely but finding places to drill for screws is limited. I used trail and error to find the hole under the foreward bottom skin. Missed by just 1/8" on my first try drilling and hit the steel plate that is on the gear leg weldment. Then figured a way to calculate and draw a line on the bottom skin that was approx. 1/4" forward of the edge of the steel plate on the gear leg weldment. It is a line four and a half rivets outboard of the floor stiffener rivet along the span wise row of rivets in the bottom skin and foreword center section flange. I drew a line 45 degrees off that line and this approximates a line about 1/4" forward and parallel to the fore edge of the steel plate on the gear leg weldment. With the intersection fairing held in place, the "sweet spot" for drilling is apparent. The other two screws were, one in the wing root fairing and one aft of the center section under the outboard seat bay. Had to use a rivnut there. I used #6 screws with tinnerman washers for my intersection fairings.

RivetSizer iPhone App is finally a reality! |
|
I finally got my RivetSizer iPhone app up and running. I was approved and went live on the App Store a couple of days ago. It calculates the rivet length as the user inputs metal thicknesses. You can choose which rivet diameter you need too. It is meant for metal airplane builders so RV builders may enjoy it. It is meant to be quick, and I think I have accomplished this. It was a bucket list item to actually learn how to program an iPhone app. Visit the app store and search rivet sizer. Or click this link: RivetSizer on the app store. or visit the blog I set up for it at RivetSizer.com.

Installed control column, sticks, pushrod, right fuel vent line in fuse |
|
Got back to building today. Installed the control column, sticks and column pushrod. Took a while to get the washers in. Had to adjust the sticks several times to get them parallel. The dimension of 18.875" for the pushrod is a little long. Then started on the fuel vent lines. I have my spring benders from ACS, so this is a lot easier. I cut about a seven foot length of the 1/4" versatube and worked from the F-902 vertical bulkhead fitting, bending and clamping as I went all the way to the vent fitting in the fuse floor. Be sure to trim the Adel clamp screw in the F-684 gusset, or it will put a dent or hole in the 970 side skin when screwed in all the way. This is mentioned on DWG 36A, ISO FRONT VIEW. Also be mindful of where you located the Adel clamp in the upper F-695 gusset so to have enough clearance from WD-602 upper firewall weldment for installing the nut and washer. Got lucky on my first try. It was close. Also finished the fuel line that goes from the fuel valve to the fuel pump. I have the fuel pump installed and am using the "RAF approved" swivel fitting to connect the line to the fuel pump. Sure made it easy. Not sure if I need an expansion bend somewhere in this length. I'll ask my teck advisor later.
