One would think with all these tools out, aluminum shavings and chips, more would be done. Oh well, one piece at a time!Comment

Progress is sometimes measured in mm of posterboard. Lol. Tomorrow i convert these to aluminum!Comment

Lots to building baffles from scratch, almost done thoComment

I admire the talent it takes to make baffling from scratch. I'm so glad I bought the Van's baffling kit.Comment

Thanks, wish I could have bought some. Just couldn't find anything suitable for the O200 and LSA cowl.Originally posted by rodsmith View PostComment

Third attempt at the carb cowl. I really don't like the square shape on a curved cowl. Just me i guess

It is definitely a tricky spot! On our first plane I used the Vans FAB. I got the scoop from an RV builder and made new composite material to interface that with the aluminum of the cowl. If you want more curves, an option is to make up what you want by carving foam, then laying up composite material on your carved foam. This is a way to build whole cowls, just think of how much easier it will be to just make an intake scoop!Comment

I hope to fab one from aluminum, a few curves, but main goals are weight reduction and maintenance friendly, want to be able to remove the scoop from lower cowl for oil changes. With the O200 I don't see how the RV fab would be a good solution. So, off I go. ?Originally posted by jaredyates View PostComment

Well, I scrapped last night's efforts this morning. ? Compromise is a necessity whe completion is priority!
It has curves, very subtle tho. Will hopefully finish up tomorrow.
Goals were met, its fairly light and will be attached with screws to allow easy access to lower inner cowl for oil change.

Today I installed the rubber seal on baffles, so calling that part ✔️.
Now, confession time. Two weeks ago while finishing up the cowl i realized there wasn't enough space for a spinner back plate ?.....
Crap, what to do? I took some measurements, needed .40" more to clear the backplate. Called Sam at Saber mfg. Ordered extended drive lugs, upsized bolts to 7/16", got a .40" engine to prop spacer, while at it increased the face diameter to 6" for better clamping pressure. Had to fabricate a press to get the old lugs out, it never ends ?
All that done.
Short list gettin shorter!!!Comment

Calling the firewall forward done! Hope to run the engine next week. Just have to paint a few things, set timing, fuel flow test. If that goes well. AW inspection will be scheduled. Yee Haw! ?Comment
