I'll try that.

 

My shop is getting sub 60 degs F at night, so I brought the LG bulkhead into the house this morning to fully cure.

 

I still need to do the permanent firewall, which I didn't want to do until I was absolutely certain I had the proper dimensions (considering the widened rear). That should be straightforward -- just trace the temporary firewall.

I'm in 3D mode... fuselage assembly. Check my web site if interested.

Thanks Carlos. I'm watching for that landing gear section you mentioned got to be a bit "odd". I have all bulkheads except landing gear and firewall bulkheads floxed in. Still need to tape, but feel like I'm making progress because I can see this new "thing" in my garage now.

Shouldn't you tape at the same time you flox? I'd think you'd get a nicer finish and better bond if the flox was still wet when you put on the tape - and youwould not have to sand again. That's what I'm planning to do tonight when I put the 4-uni layers on the upper longerons. I'm going to use some flox to make a smooth transition from the longerons to the fuselage sides, then put on the cloth.

Generally, yes.

 

I'd think you'd get a nicer finish...

I don't agree. It's hard enough to make a nice flox fillet underneath the acute angle of the seatback, let alone tape glass in there without squeezing your fillets all over the place.

 

...and better bond if the flox was still wet when you put on the tape - and youwould not have to sand again.

That's the only trade-off, but sanding isn't that hard and I am not at all worried about delamination as a result of this approach.

 

That's what I'm planning to do tonight when I put the 4-uni layers on the upper longerons. I'm going to use some flox to make a smooth transition from the longerons to the fuselage sides, then put on the cloth.

I did the longeron flox fillets at the time the longerons were mounted to the sides.

 

Sanding the flox fillets rough and raw is easy (although requires more time) with a carbide Permagrit dremel bit. The result is a perfect fillet that won't move during taping. YMMV -- if in doubt, do it per plans of course. Let me know.

A neat trick to smooth out flox is by brushing a bit of pure epoxy over the flox. I think I saw that on Bernie Siu's web page.

I taped tonight, and had your question in my head. The plans have you flox first, fillet, cure 24 hours, and then tape the next session.

Sounds like what you're supposed to do anyway -- paint the surface to be mated with a light film of epoxy. Then again, doesn't matter what I say because I can feel my brain learning as I move along. I can't say I had a perfect taping session, but it will do.

Your project is looking great, keep pluggin away, It takes a lot of dedication and focus but the end result is well worth the effort. I should have my AC 99.99% completed this week end. If you are in th area, give me a call and I will take you for a ride.

Thanks Jack! I guess I'm trying to catch up to Remi. :) I think the project taking a recognizable shape keeps me going now. I'm about ready to set my landing gear bulkheads. You said it, "everyone, keep going!"

 

I hear you've got some performance improvements happening. Sounds like an even better plane than it ever was. I'll have to end up in your neck of the woods one of these days.

I'll let you know soon how my LG bulkheads align to LWX and LWY -- that's my next step.

Actually, my next steps are:

 

1a) 4-bid reinforcements on F22

1b) 2-bid tape bottom 2" part of IP (beneath bottom hole on side)

2) Install F28

3) LG bulkheads

 

At least 3 nights/sessions of work I estimate, depending on the size of the session. :o

 

I should have my AC 99.99% completed this week end.

How'd you make out Jack? Four nines is impressive!

Welllll, got the first 99 but the last.99, not even close. Im in the process of wiring my nav/strobe lights as of tonight. Still have a few items to finish but hopefully I should have it in the air Sunday. It will be interesting to see if there any improvements in AS with the airframe painted and clean. I'll let you know if there is any noticable increase.

Jack, I re-watched your segment on the Canard Special DVD to get some additional motivation. Actually, I wanted to see how your forward opening canopy was hinged and mounted. I have seen the E-Racer plans in this area. Looks straightforward with the right layup schedule.

 

If the weather keeps me from the Great Pumpkin Fly-in, I'll be installing the landing gear bulkheads this weekend. After that, will be looking forward to working on the bottom.

The E Racer forward hinged canopy was not very difficult to do. I changed mine a little because I extended the canopy frame forward 5 inches to give more access to the instruments. I am also using a Cozy 4 lens on my canopy. If you need templates for the hinges, let me know and I will be happy to send them to you. If you noticed at RR, I had center pull down catches. Since I replaced the original lens with the Cozy 4 lens and installed the lens to the frame, I put a 1/4 in block at the rear edge of the canopy frame and pulled the center catches down tight and let cure. I now no longer need the center catches and the catches at the rear of the canopy pull the canopy tight, even at 290+ mph. I have since eliminated the center canopy latches. All I use for sealing and rain is the 5/16 P stripping.

What interests me most with the ERacer canopy hing is that the gas struts are mounted directly to the hings AND hidden forward of the panel. Seems like a lot of force would be required to make that happen, but obviously it works.

 

I took a look at the ERacer plans and have good notes for retrofit into my Cozy. Any help would be appreciated, and I'll be sure to ask more questions when I'm closer to that part. I was thinking whether I needed to strengthen F28 (your FS28) at this point, but decided to proceed to plans as I can do that later if necessary.

I did not have to reinforce the fs28 bulkhead for the hinges. The only change when I extended the canopy frame forward 5 inches, I had to go from a 80lb shock to a 100 lb shock, works great with no problem so far. By the way, I finisned the nav/strobe lights tonight. Am working on a electronic wastegate control system for better low cruise fuel burn, looks very promising.

I'll have to take another look at how that shock gets supported.

I thought you don't worry about things like that with 6-cylinder engines. ;)

 

My bulb burnt out in my hotbox and I'm waiting for it to warm up so I can finish my fuselage assembly...

I tested the wastegate controller tonight on static runup and it worked as expected. I am hoping I will see about a 25% reduction in fuel burn at low cruise, 230 mph. That should increase my range considerably, testing at altitude will verify that. In regard to the foam post, I was just being concerned. If the 1.6 is good to go, go for it.

Sounds like a great improvement.

 

I appreciate your input on the foam discussion. I went into "oh sh*t" mode again until I redid the same research as when I decided to buy. I also got a nod from someone who's knowledge I value. Still, the plans call for different "material", but I'm comfortable.

I finally got enough confidence to mount my LG bulkheads this past week. I'm locked in now! :)

It took some careful adjusting to get everything to fit, but I managed. Just need to clean-up all the tapes and then... not sure what's next. Floor? Oh yeah, no, my permanent firewall!

How's this for not turning out as I had planned (notice the cut bulkhead)?

I flipped my fuselage this past weekend, in preparation for doing the seatback brace, heat duct, and bottom.

 

Only minor issue is that when I ordered chapter kits from Wicks (almost 3 years ago), they forgot to include a 1/4" x 2' x 4' piece of Last-a-Foam. We'll see how good their customer service really is when I try to explain myself. :rolleyes:

I've worked 5 more hours on the underside (sanding and taping inside LG bulkheads) and STILL need to get to my heat duct and seatback brace.

 

My strategy is to work in the shop more and more each evening, somehow forcing the weather to warm up a bit. :rolleyes:

If you need it to get warmer in the garage. Get a heater and force it to get warm. I have a wood stove and a Propane furnace. I generally only have to heat it in the morning now it stays pretty warm the rest of the day. STeve
