Default Not doing that

I am not doing that. in fact I don't think that will work on the RV7A/9A slider; the inner glare shield is too far away. I would recommend NOT doing that. JMHO.

To be honest I'm not at all comfortable with that design idea either. It would be tricky to locate the slot in the correct position and if it turns out to be incorrect, then what...

Will be glad when the canopy is done and it turns out OK.

Default Windscreen glued in

I just got the windscreen glued in with sikaflex. What a mess.
First, I made up spacers that go on the roll bar to set the height of the windscreen to match the canopy.
Second, I used 1/2” 3m fine line tape to mark where I wanted the glue on the plane and then matched to the windscreen when in position. I then added fine line tape to each side, and removed the original tape marking the bonding location on both. This left a double line on the windscreen and fuselage defining where the primer and glue would go.
Lastly, I applied activator and primer to canopy and windscreen. Then applied sika to the fuselage (rollbar) and carefully positioned the windscreen on fuselage and clamped.

Once I started breathing again, I pulled off the fine line tape, leaving a nice, clean fillet.

After the sika dries and I get all the stuff out of my hair, I will remove the spacers and fill in the fillet to make it look pretty.

Update: Next time I will remove the tape on the inside, between the windscreen and the glare shield prior to marrying the windscreen to the fuselage/roll bar; it is very difficult to remove once assembled. This means care must be taken in applying the glue to the fuselage and roll bar because the tape will no longer save a messy install.

Default Test Flight

It seems I am nearing the end, and time to start thinking about test flying.
I was planning on renting a hangar at another airport one hour away for my first flight and to fly off the hours. That plan got shot down. It seems the airport will only lease hangars to planes that have an airworthiness certificate. So I cant get a hangar until I am ready to fly.
Gotta find a plan B.

Try contacting the EAA chapter at Cable. You can finish off the airplane there and do Phase 1.

Default Fiberglassing

After taking a few days off, I have started fiberglassing the wind screen fairing. I am following the excellent tips and tricks from the Osh 2021 presentations. I had visions of making a really neat layup, much like the Osh demo, but that went out the window after my first layup. I am using black tint on the first few layers so when looking from the inside thru the canopy, one would see black fiberglass. Of course, it never occurred to me to use a vinyl tape color other than black, so I am finding it hard to se the tape edge when laying down the fiberglass. It is going much slower than expected, and I am burning thru more glass than I planned.

Onward so I get upward.

June EDIT: There is no need to add dye to the fiberglass layers if one is using Sika flex or if one is bonding the fairing onto the plane after it has been molded. The exposed pieces will need to be filled and painted anyways, and the part that show thru the plexiglass will be coated with sikaflex black primer. my parts did not come out perfect, so the black fiberglass bits still need filling, priming and painting.

I collected a bunch of cheap (garage sale) wrenches and bent & grind them to fit in each unique area, each specific to a particular nut. I think I ended up with 6 unique wrenches.

Front windscreen fiberglassing is done. I popped it off to trim and finish. Learned a lot this time, but didnt learn enough to make it worthwhile to redo.

Default Sanding windscreen fairing

Sanding windscreen fairing. I made a sanding block use my french curve from high school and belt sander. I used aeropoxy and the stuff is pretty hard and sands well. Next step will be to smooth edges and start filling outside to smooth contour.

The sanding block allows me to sandxat an angle and match the desired curve.

I thought I was building a metal airplane.
