Is the stainless firewall with fiberfrax insufficient? What is your line of thought here Jereme.

Looking great all the same.
Good questions Kent. The fiberfrax is sandwiched between the firewall and the titanium, putting it inside the cockpit is basically the biggest no no as it off gases when heated. The fiberfrax is a paper/fabric type stuff so you have to put something over it to protect it. Many people just use sainless foil but it has a lot of wrinkles and just doesn't look good in my opinion. Dan H has some really good write ups on the topic, he even tested many things on a firewall heated to around 2000 Fahrenheit.

Very shiny! Looking at this is an inspiration to keep working Jereme! Thanks for the kick in the rear-end!

Haha no problem Kent glad to help! I'll post pics soon of my canopy frame all bent properly, wow was that a chore.

Please look at post 425 here before copying this ANL/shunt setup.

Well after bending the canopy frame to satisfaction I figured I mind as well go back and finish up the firewall. I installed the hinges on the lower half for the cowl. All that is left to do at this point with the firewall modification is to tape the seams with aluminum tape and throw in some of the magic goop (3M Fire Barrier Sealant 2000+) around the perimeter where the hinges are.

Over all I am SUPER pleased with how this came out. There are no noticeable wrinkles, only slight distortion of light (worse in the picture than in real life even). If you want to go with fire protection that looks sweet as well I think this is the way to go.

Oh this also happened while drilling the top cowl hinge. Right when I was thinking "man I might actually make it through this build without drilling a finger". Turns out that a #43 bit spinning at 4000 RPM will in fact go underneath and then through a finger nail. Who would of thought... Good thing I just got a tetanus shot.

Jereme, How did that canopy frame go?
Looking really good! What do all those articulated eyeballs to the left do? And to the left upper? I don't have an idea about my setup yet as I am not there yet.

Awesome!

Kent, the canopy frame bending is a real test of patience but I think I finally got it. I'll try and post pics of it later today. I was getting REALLY frustrated with it at one point because the plans say the rear bow needs to be inset 1/16" from the aft top skin all the way around which now looking at it it seems impossible to do that as it would push the bottom side bows too far out. I settled on close enough and symmetrical (the bubble is going to change the shape to a degree anyways so I'm not stressing over fit until I clamp the plexi on). I think the important part is that the rear bows are inset to some degree (especially since I plan on doing fiberglass skirts).

Here is a pic of what things on the firewall are for you and anyone else that is curious (I know I had a hard time finding something like this when I started working on the firewall).

So I am good I don't use any of the three on the right in the picture, save for maybe alt air. What does that do? Outside of the obvious..

Or the oil shutter, never too hot never too cold in Oregon.

Just to clarify as well, all of them locations are for the fuel injected horizontal intake engine. The alternate air pass through is for the cable that opens a little door in the intake tube/plenum just past the air filter in case it ever gets blocked. As far as the shutter goes you probably don't need it where you live but I don't know. Where I live I know guys that have to tape their oil cooler completely off in winter. I'd rather be able to control it with a less "gheto" feel. haha This is the shutter. I also came up with what I thought the best area for the pass through was on that one.

Here are some pics of my canopy frame after bending. If anyone sees any problems or areas that need adjusted please please post or PM me. The only thing I haven't done yet is bring things in about 1/2" to account for canopy spread.
