Default Tough Micro

This weekend, I had to REMOVE the micro from the fuselage around the gear leg opening so I could get a glass to glass bond for my intersection fairings. Being that I did a less than stellar job carving the corners of the fuselage (the contouring tool wasn't invented yet), there was a fair bit of beautiful micro there. I'd say 3/16th of an inch.

I thought I'd try 80 grit to remove it. Nope. Switch to 60? Nope. 36? Nope. I would have been at it all day.

I ended up using a wire wheel and my drill.

Micro is tough stuff when applied correctly. It won't fall off.

Wayne - we knows that the thermal charactics of the pour foam are bad, what are the thermal charactics of this foam?

does it continue to change volume with temp changes?

Right now, there's no foam in my intersection fairings. I used the pour foam as a mold, then removed it after the fairings were glassed. But I am thinking about putting the foam back into the fairings to help stabilize them. I'm not at all worried about any foam expansion issues on these fairings. There's too little of it and it's not encased. It can expand if it wants to without issues.

On your gear leg fairings, they look real nice. Make sure thee is a little room so the gear leg can flex.

My fairings look just like yours maybe a little longer and low and behold
the gear leg flexed enough to crack fairing.

After repair I cut them so I would have about a 1/8th inch clearance.

Just an FYI
