Even my usually VERY understanding wife couldn't help but tactfully ask "when will those wing tanks be done?", knowing that the godawfully smelly epoxy would be done with as well. Hurricane ventilation is a must. I have an attic fan sucking the air out of the basement right now , and that's just about what it takes to keep the smell out of the rest of the house. I don't think I'd go quite so far as to say that it might be safe. The catalyst is MEKP, one drop of which will blind you permanently if you get it in your eye. And it is the only epoxy that I've ever bought that I had to pay a "hazardous material" fee on when I got it from AS&S. Some of the chemists might elaborate on that. I've found the easiest way to measure the catalyst is with a syringe. There are 48 drops of catalyst per cc of MEKP. And since one gram of MEKP=1cc, it's pretty easy to come up with the 1-3% ratio using the syringe as a dropper. I measure stuff in grams, but it's 28 grams/ounce if you're into ounces. That's another thing about vinyl ester. Large batches "go off" even faster than small ones, so don't do it. I just installed my wing tank tops (permanently) and I mixed 50 grams to brush onto the top and "capstrips", and another 100 grams to mix into flox. I plan to do the other tank this afternoon. Webpage update tonight, maybe. Vinyl ester is reputed to be corrosion and fuel proof though, which is why I made my fuel tanks out of it. Some people swear by it, some people hate it. I DESPISE it! But that would be beating another dead horse, I guess...

I spent most of last week driving out to apply filler to the bottom of my airplane and spent about 1 hour yesterday sanding one wing. Its looking great and I only need to apply a little filler in about 3 small places to sand again. I used the air board to sand the wing and its works great! Like I said only one hour and the wing is flat, smooth and almost ready to prime! Today I will sand the other wing and apply filler to required areas. I should ba able to prime the bottom next weekend and flip her back over on her wheels. This is getting exciting! Filler tip for those of you using or planning to use superfil (or any filler for that matter), apply enough filler to get it right the first time. Even if you have to apply filler on top of filler you haven't sanded yet. This keeps the hard spots from forming. If you sand the filler and then apply more you will create hard spots that are a &^%#$%^ to smooth out. Off to the hanger for now, oh yeah info on the tailwheel manufacturer is below.

Ross- if it's not already on the KRNet.org web page- fire up the scanner and put that photo up. And for you short-wing Piper fans (me, too) note that there's a guy who homebuilt a PA-16 lookalike. I love it! That's a great little plane! Also- be sure to look at Mike Mims' May update web page for his flippin' rocking chair thingie. Real cute. Also- Mike- are your wings missing some span yet, or did you whack off some of the 'plans-built' span? They sure look stubby. I successfully passed another BFR this morning, simultaneous with getting an insurance checkride in the FBO's Skylane. (Quite much nicer than last time in a Skylane RG, when the gear failed to come down and we had to armstrong them down. Very short checkride that time). There were Young Eagle flights all over the place today (it was the second day of the local EAA chapter's Family Fun Fly-In), with Glasair, Lancair, RVs, Kitfoxes, T-craft, short-wing Pipers, an L-bird, Ercoupe, "Nieuport", bipes, but no KRs. Good ol' netter Paul Martin was behind the griddle, watching pancakes and eggs cook. His KR was safely back home in his garage, cuz the weather-guessers thought it might rain this weekend. (Ha!

I wasn't aware it was MEKP, although I think it's on the tube. I made a pinhole in the cap of the catalyst tube and it gives very nice drops to measure with. This being the case, how many drops would 1oz of resin require to set off at 90deg F.? Dan suggest 3-4 drops per ounce, but your formula comes up with 13 drops per ounce at 1%. An ounce is 28 grams, 1% is .28 grams, 48 drops of MEKP per gram, so 13.44 drops is 1%. If this is the case, I have been using too little catalyst. How long is it supposed to take to harden to sandable texture? My wife didn't divorce me, but did ask what I was mixing today that stunk up the house. It's going to be difficult to keep the smell out since the garage is attached. Maybe the West epoxy would be cheaper than vinyl ester if I don't have to get divorced. - -Tom Mark Langford wrote: > Tom wrote: > > > One thing I noticed about vinlyester resin is that it seems to > > lighten the wallet > > a lot less than most epoxies.

Netters, I have been using TR-88 for all of the wood joints, and so far I have really liked the stuff. I always try to get the ratio as close to 50/50 as possible - usually using a syringe, and I test all of the joints (very scientifically - usually a good stiff tug or twist.) The other day 2 joints failed. This is the first time that this has happened. Kinda makes me wonder about other joints. I thought that the strength of a T-88 joint was fairly independent of the clamping pressure that is used. (Both of these joints were well coated with epoxy but had very light clamping while they cured.) Does anybody else have any experience with this? The other thing that I noticed is that there seems to be a reaction taking place in the hardener syringe; a hazy region adjacent to the rubber plunger. I wonder if this is the strength culprit?

Parker No. He was close to the airport, so they towed the plane to the airport. He wanted to do a thorough inspection of the plane before it flew again to absolutely confirm beyond all doubt that the mag switch was the problem.

The clamping pressure is supposed to be moderate to light.

If he's selling it for $30 it must not be the same as the AS&S version, which is more expensive. There are different levels of "promotion" in which promoter is added at the factory. Maybe yours is more promoted than mine. My experience is only with the vinyl ester that AS&S sells, which they call "medium". Their sparse directions call for mixing 1-3% catalyst "depending on temperature and desired working time". I've yet to try more than 1%, and it's ready to sand in a less than a day. My basement stays at about 70 degrees and it starts getting hard to work with after 10 or 15 minutes. One of the nice things about it is that you can use it in place of 5 minute epoxy if you add enough catalyst. I wouldn't worry too much about using too little catalyst. I think if it's been promoted it will harden eventually no matter what...

You answered my next question about hardening eventually if I used too little catalyst. I had misread the catalyst needed per ounce. I've been using 4 drops per ounce instead of 12 drops. Today was my first experience with the stuff and I glassed the wingtips on my 1/4 scale KR-2S. I think it'll be a week before the tips harden! - -Tom Mark Langford wrote: > Tom Andersen wrote: > > > This being the case, how many drops would 1oz > > of resin require to > > set off at 90deg F.?

PinHoleHeads, We had a discussion on fillers a while back (Tom's post reminded me). What's the name of the new water based pinhole filler that works miracles?

It works for filling pin holes too. I plan to use Smooth Prime from Stits and mix a little micro balloons in for small pin holes.
