    RE: Intrested? I'm Bashing a Tiger60

    I finally got the plug ready to glass, it wasn't without some of the same problem with the bubbles and I dont think it was becsuse of air in the mix. The 30 min. epoxy had denatured alcohol added so it would brush on smoother, because 3/4's of cowl didn't have the bubbles only the last section (top) had them so I think activation played a part because the cup of epoxy boiled into foam and got real hot. I tried to brush out the bubbles but they wouldn't brush out. I'm not sure what was going on. I got it all sanded out again down to 1500 grit buffed it and added the 3 coats of wax and I think I'm good to go.

    I don't expect to save the plug giving the problems I have had, will find out when I take the cowl off it. Sure would like to know what the epoxy was doing, could the alcohol have something to do with it. This has sure been intresting to say the least.

    Anyone wanting to build a cowl don't do it the way I did.

    RE: Intrested? I'm Bashing a Tiger60

    Never tried to use alcohol to thin epoxy, and those bubbles might have been water coming out of solution. Store bought alcohol can contain water as will absorb it from air quite readily. The plug looks great though! Looking forward to the next steps of the process.

    By the way, I followed some of the links in the earlier posts and this one has some great diagrams at the bottom of the page. I'll post it again as it is one of the better descriptions I have seen.

    Leroy, have you tried using Zpoxy? I find it to be very user friendly.

    What you experienced is a very common occurrence in epoxy volume mixtures of as low as a 300 gram mass, it is an exothermic reaction of the mixed resin and the hardener. In short you had what is commonly referred to as a case of thermal runaway, in mass it continues to generate heat until it exhaust the energy caused by the mixed chemicals, during this process it could and in most cases reach several hundred degrees before it cools back to ambient.

    TB I have never used zpoxy, don't even know what it is. I do know I have my hands full with what I am useing but getting it done just the same.

    Toivo thanks for that web site, there is alot of info. there and the guys at ccomposits are helping out also, almost have it done, just alot of work. There arn't many short cuts doing this thats for sure. There are a lot of products you can use some cost a fortune and I don't have one.

    Z-POXY finishing Resin is a safe, odorless, Equal mix epoxy for use on any model. It's clear, easily sandable formula sets to a tough, no-brittle coating that fills the weave in fiberglass cloth and small surface imperfections. It sand to a smooth, even surface, ready for priming and painting. It is also an ideal laminating adhesive that cures with no wax film.

    RE: Intrested? I'm Bashing a Tiger60

    Huston I don't have a problem but I do have a cowling, he he. I'm a happy camper now. All good things must come to an end in spite of the way I got there. A cowling makes the plane, sorta and having made my first one has it's rewards, "you can't buy this one", matter a fact you cant buy this plane in it's present form. I do have a one of a kind and it's been fun building it. Sometimes you start a build like this and are not shure how it's going to turn out until you get as far as I have and I'm very pleased. Bashing the right plane helps and the Tiger has proven to be easy to bash, I'm glad I chose it. It won't be long before I get it done as I only have alot of small stuff to do. I have yet to come up with a scheme and colors yet.

    Here is how my cowling came out and I really like the look on the plane. Leroy

    Well internet is on the fritz, will do it later. Could be the storm .

    RE: Intrested? I'm Bashing a Tiger60

    Having the cowl finished I just had to put it together again and have another look, I sure do like it and find it amazing what can be done with these kits. I have enjoyed this so much I think I will look at other kits and bash another up the road.

    Will share it with you and maybe inspire others of you to give this a try, fun stuff[8D]

    RE: Intrested? I'm Bashing a Tiger60

    There may be someone intrested in adding a DLE 20cc to your Tiger 60, the biggest problem is a narrow fire wall (engine mount) but that can be an easy fix by widening it to 4". Mufflers will also add to the problem as most require cutting up the cheeks or cowling if it has one. I contacted Jtec with my information and they have one that will fit my install, it's a compact pitt's in cowl muffler for this engine, Tower Hobby has them now and I got one, you just have to order the compact DLE 20cc muffler, it fits real nicely on my plane.

    Got the wheel pants and covering now and am doing the wing tips so should get to the covering shortly. Getting close to the finish, still have to break in engine and figure out how to fasten the wheel pants to my gear.

    As usual, no upload this time of day.

    Thanks Steven, this has been a fun build and my first bash. I chose the Tiger 60 because it is an easy plane to accept the changes I have made and not loose the great flying charateristics, I may have improved them, at least that is my intention.

    Wow, 4 on the boards, sounds like you have your hands full, I'm to old to try and build more than one at a time, ha ha and I have 3 others I'm yet to fly. This year is my year to fly, retired and owe myself lots of air time, something I haven't had much of in the past 3 yr's

    RE: Intrested? I'm Bashing a Tiger60

    After looking at finish schemes for the last week I still do not have a scheme so will just do it off the cuff and wish for the best. Fuselage is the hardest to do, because of it's shape there is a limit as I see it to what can be done. Wings being sheeted will be my first and air pockets is what I fear most, open frame is alot easier. Colors I'm using are red,blue, white, red & white checkers and chrome for accents. Ultracote is the covering except for the chrome which is kinda like vinyl but is real metal, I forget the name of it and it's only .08 mills thick, very light weight and I have to be careful getting it on. It is going to test my skills (which I have little of, I'm a painter) to the limit.

    Will start on fuselage first, tail stablilizers will be on the plane when I do it. Hope it goes well.

    Will post pict's as I get some done.

    If it works for you there is still a wrong way
