I've not been doing much building or flying around the holidays, but I finally got inspired to start working on the Dreadnought again. Two days of therapeutic sanding and shaping (with the Dremel and mostly by hand) and I've got the cowl fitted around the PA .75. Its now ready for blending around the spinner and final sanding. I'm not sure how many "tools" with sandpaper glued to them that I used, but I made a few more for the task. The more I build the more I enjoy sanding, used to hate it!
Happy Holidays!

Muffler, eh? Is that gold plated LG & wheel panties from Randy Aero? Had to do it, you understand. Looks very nice, as usual! y1 Steve

I was unable to obtain a header and pipe in a timely manner, so I opted to go with a muffler since I want to get this one done for the 2018 season. The landing gear and wheel pants are the only thing that remained from my last plane that was destroyed on pavement (yep, trashed the engine too), I just haven't gotten around to sanding them down in preps for a different paint scheme.

Nicely done. Thanks for sharing your work.
Very cool seeing the process in action.
Kinda clears up a few questions I had about fancy cowl construction techniques.

Hi Don,
Nice work and looks great. Now put a layer of .5 glass on the nose & cowl with epoxy to keep it looking good for a long time. Also coat the inside of the cowl and tank compartment as well. Keep up the good work.

Thanks Mikey. This entire plane will be covered in .5 ounce glass cloth and epoxy resin, then primed and painted with Klass Kote Epoxy products. The wing and tail are already covered, next step is to attach them! I'm weighing everything as I go so I can defend using this finishing method against the skeptics that say it will be too heavy. I'm shooting to keep this one at or less than 64 ounces.

I've found that I can apply .56-oz glass with epoxy at or below the weight of even a doped surface because of the small amount of epoxy necessary to fill. This is under the condition that I keep the glass against the surface - no floating, as seems to occur with dope.

Hi Don,
I haven’t used Klass Kote Epoxy products before, so I’ll take your word for it. The last stuff I used is K&B epoxy and that worked awesome. Years ago before there was vaccume bagging, I used .75 glass cloth and K&B clear epoxy to attach the cloth, place a layer of plastic wrap over the glassed wing and squeeze out the excess epoxy. Let it cure over night and when the plastic wrap was remover you had a perfectly smooth surface. This method worked great on team racers and Goodyear. I used the same method on wheel pants a few times and they turned out great.
Where are you getting the Klass Kote products?
Thanks,
Mikey
