Rich, hope this works. What color buffing compound are you using? I have green which I have used on stainless with good results. I picked one at random from Ace. It's a black color solid stick that one sort of melts onto the buffing wheel. I'm surprised that it seems to be removing that black oxida...

Holding the shell with one hand and a buffer wheel mounted on a drill with the other are a challenge. :roll: Video could be amusing... :D Or at least before- and after- photos might motivate me to attempt it with my exhaust stack... Steve I see we have a grinding wheel in our EAA hangar. I'll put a...

There was a guy at KLFT (I forget his name now) who owned 40.048 (1 SN lower than my airplane). I stopped in to visit him on one of our trips to FL in 2002 or 2003. He liked to polish his exhaust stack (original exhaust configuration). The thing was like a mirror. Mine looked positively gross next ...

The video won't play for me. But an EGT rise on a cylinder accompanying the RPM drop would indicate a plug misfiring. An EGT rise on all cylinders suggests a mag problem or p-lead intermittent short.

If the idle is set too low this could happen. My static idle, which I go to right before engine shutdown, is about 640 RPM, with a partially leaned mixture. There is also the matter of setting the idle mixture properly. And mag timing. Keep in mind that mags have a much weaker spark at low RPM than ...

Another experiment: With the replacement of the super-flimsy vent latches I thought I'd see how it might be with the iPad mounted to the vent window. Seems pretty cool. Although this picture shows it in landscape orientation, I plan to use it in portrait, as it moves more of the display inward towar...

My insurance policy renews in October. My last 3 annual premiums were unchanged. I have lower limits for hull - $125K. $1,569 from Avemco. Just got my Avemco bill for this year (due Sept.). The last several years were just under $1100. This year $1420. $110K hull. Being 73 years old might be a fact...

I have powerflo with ceramic coating. After about 250 hours, the last 10 inches are still shiny but farther up the barrel the coating has darkened. Slight improvement with polishing with Flitz. Insert still looks in good shape. Good to know. The insert does outlast the glass by quite a bit. As I no...

I'm about ready to pull the trigger. I know the numbers are off a bit. Useful load is about 1100, but the fuel burn is closer to 14.5, not the 10 they advertise. The cruise didn't hit 200 knots, but it is 190+. It's spin rated, Garmin G3X avionics, ballistic chute, more interior room, and currently...

Just wanted to say my left leg is tired after a 3.5hr flight with the corked wheel. This seems like a silly problem to have. Do other aircraft types have similar issues? If this is always the case, adjusting the rudder trim tab is in order. No, its definitely the corked nosewheel issues. Took off w...
