Hi Brad. I just took a look at the photos on your web site of your broken up practice fuselage. You didn't support your timbers with gussets which increase the the contact area of a joint around 6 fold (along the bottom and up the sides). T-88 is considered among the best epoxies for the job.

Do you have anyone also using T88 near you or in your EAA Chapter? As with the others, I found T88 very reliable. If it goes thermal as you use it, you know as it is very hot. It also is a non-critical 50/50 mix and should not pose a problem there. Could it have frozen coming in from Wicks?

I just opened my bottles of T88 too last week. In mine, the amber resin is also thicker than the transparent hardener. After mixing it is a thick white color goop. Kind of hard to spread. After drying over night, it is transparent with little color. The box does say, the strength of the

The only time I have ever seem T-88 epoxy look whitish is when it is whipped up vigorously, intrapping air in it. It should be stirred and maybe slightly warmed so the air bubbles can escape if that is indeed what is happening. Usually the air will escape by itself when applied to the part and

I squeeze the T-88 hardener onto a flat surface "pallet" that I am going to mix it on. Then beside it, I squeeze the resin. I try to get the same diameter and height circle for each. I do the hardener first because it settles slower. I have even drawn circles on the pallet to give me something to

This may start a info storm on the kr net but it's my understanding that sanding end cuts is a no no for 2 reasons. first being a fresh cut exposes end grain of the wood and sanding knocks the exposed cut end of the long indiviual wood fiber over and the adhesive can't wick into the cut end.

One of the properties of epoxy is it's ability to soak into the wood. As the epoxy cures, the bonded epoxy includes the wood which had soaked up the epoxy. I believe what you say is correct to a point, but the soaking of epoxy into wood is completely blocked by the sanding process. On the

Hi all, I've started to lay the timber out ready for gluing the fuselage sides, and was wondering, what's the best way to clean up excess glue from the joints?? Am I better to wipe it off while still wet? or am I better to let it dry and chip it off? Which is less messy and most successful?

Hello Gavin, I prefer to mask around the joints with low adhesion and residue tape, and this way simply avoid the glue clean up mess. If you do not prevent the excess glue mess, none of the cleaning methods are any fun. Todd Servaes KR-2S Gavin Donohoe wrote: >Hi all, >I've started to lay

Hi Gavin. Definetly clean up excess glue before it sets up. If you wait till it cures and then chip if off, it's not only a lot of hard work, messy when you're finished, and you run the risk of shattering the joint! As for your spar, laminate it up in 1/4" sections or so. 1" thick laminates
