Can't wait to see the Fuzzy Dice !

I just found a neat photo from 1977 ish. N45881 was almost done. I'm in the basement assisting in the build with my father.

Last week we leveled the airplane, measured and fit the 521's. Welded them, installed and done. Also got the panel switch labels back from the local trophy shop.

I had a few hours to work on TH this afternoon. I was able to get the engine hung and the prop installed

Looking good Billy Ray !

I couldn't resist getting the cowl parts out to see how they fit. I like seeing progress.

Awesome work!

It is very hard to tell by the photos, but does the plenum allow for any air to get back to the magnetos and accessory case? Can the mags get too hot where maybe a blast tube of cool air on them would be a good idea?

Just my novice thinking here.

It is never a bad idea to keep the mags as cool as you can. I have had cold air blast tubes from the rear baffle down to each mag as well as to the gascolarer for many years.

Me too use blast tubes with my enclosed plenum for the mags and fuel pump .

RB

Steve, can you supply a picture sometime on how you routed your blast tube down to your fuel pump? I'd like to see where on the plenum you attached the tube and what diameter tube you used. In my case, I'd like to put some cool air on the gascolator. I don't have a fuel pump on my O-290. Thanks!

Got my blast tubes from Van's aircraft . 5/8" dia. Easy to attach to the back of the plenum . Ran one to each mag and one to my mech. fuel pump . If you go the Vans site it shows a diagram on how to attach the tube .

Thanks, Rich. I'll check it out!

I got sidetracked on another project for a few months, but am now back on TH. First up was installing the gascolator and electric fuel pump.

The only item connected to the landing gear now will be 2 adel clamps that support the exhaust tailpipe.

Last week I received my interior back from Oregon Aero. I had them sew the side panels and seats. I just couldn't get motivated to learn how to sew.



And yes the seats are as comfortable as they look. The only panel not shown in the photo is the small interior panel in front of the instrument panel frame.

Today I was drilling holes in the firewall for the alternator feed wire, starter cable, electric fuel pump wire, magneto P leads, EGT, CHT harness. As well as doing a layout on the instrument panel for what wires need to go where to talk to what....


The panel is pretty simple - Grand Rapids Sport EX7, Garmin GTR-200 Comm with built in intercom, GTX-327 Transponder - connected to the Echo Adsb and the Grand Rapids EIS4000 engine monitor. All switches - No key except to unlock the canopy.
