Fiber glassing question.
Ok, so today I plan to fiberglass my first set of floats. Not only my first floats, but my first real fiber glass job too. I was wondering about all of the screw holes for mounting the aluminum frame work. Do I just glass over them and then drill them out? Do I wait till the glass fully cures, then drill them out?

((((((((((Bristol))))))))))one of my old stomping grounds, (back in the day)(60s)
If it were me,,an what i do,(because the drill will dance around an try to go into the wood, I would take a "all" if you have one, or a finishing nail after the epoxy gets really sticky an simply use it to reestablish the hole,unless you have blind nuts , in that case youll need to fill the holes with clay of something you can dig out after epoxy sets..
I flew years ago at a water meat at "Brim-field dam"

Tape over the holes, then carefully cut the holes, cover the hole with some candle wax, , cut the excess wax flush and remove the tape,, then glass, when done I just cut the holes out and run a tap through.
Just be careful not to get the wax on the wood you want to glass,,
Good luck

RE: Fiber glassing question.
Thanks for the replys. Scale only, can you explain the tape part a little?you tape over the hole, cut the size of the hole, then what? I'm sorry, just trying to picture it. Thanks again. And falcon, what kind of clay? Where do you get it?

RE: Fiber glassing question.
Ok, I got what your saying. Just small 4 40 holes for mounting. My epoxy and hardener just came in, I think I'm going to mess around a bit first on a piece of scrap. I'm sure ill have more questions coming up. Thanks again, Steve.

RE: Fiber glassing question.
Sounds like good advise falcon. What would you do where the water rudder servo hole is?should I try to find another way to rig it and move the servo?id rather not but I don't want to make my first glass job any more difficult than it has to be.

RE: Fiber glassing question.
No, pretty much just a hole. I can look at the bottom. Should I make a box? Like I said, that's how I got them. I'm trying to post some pics, but for some reason it won't let me today.

RE: Fiber glassing question.
Yes you need a box ,,otherwise you'll fill them with water...you be surprised how wet it will get...also i would think about(what I am planning is to make a box with a hatch that can be sealed. an bury a push rod to move the water rudder..

RE: Fiber glassing question.
Hmmm, lots more to think about. Is that pretty much common practice, or do a lot of folks take the easier route and mount the servo in the fuse with bell cranks or something?i don't want to skimp out and make cheesy floats or anything, but that's a bit of work. I guess you get what you put into it. Steve.

for the one i am working on now it will get a servo burried with a hatch...an run servo wires along the wire landing gear.

RE: Fiber glassing question.
Now it let me. I'm not sure what I want to do. The cub that it is going on really isn't a crazy scale model or anything. Just a plain cub. I'm really considering just using a pull pull from the rudder or tail wheel. I have too many other projects right now, and to be honest, the main reason I am glassing these right now is so that I'm not learning on the giant scale corsair that I'm going to be glassing next. That's my main project, just practicing on the floats. That being said, I do want a nice , smooth looking pair of floats for my cub. Just not to take that much time away from other projects.

RE: Fiber glassing question.
Don't know what you plan to use to fiberglass your project. The easiest method is 1/2 oz cloth with Zap finishing resin.Brush on the two part Epoxy resin, use an old credit card to squeege off most of the excess epoxy. Let dry for A few hours then apply A second coat of resin and squeege off the excess. Let dry for A day, sand with 80 gritt to break the surface, then sand smooth with 150 gritt. Don't have to worry about the screw holes, they can be easily opened with A pick or drill bit. Good Luck, jmpups

RE: Fiber glassing question.
I'm actually using a high quality marine epoxy called Mas epoxies. Pretty expensive, but a friend of mine who is like the glass guru speaks very highly of it. I figure being that I don't have any opinion yet, I will trust his.i glassed the bottoms with 2 oz cloth, maybe a overkill, but I had it, and figured a little thicker on the bottoms won't hurt. I plan to use 3/4 oz for the rest. The bottoms seem to be doing ok. I only laid it 45 minutes ago. The test pieces I did yesterday came out good. I tried on one, filling the weave with epoxy, and with primer on the other. I like the epoxy better. Thanks again, Steve.

RE: Fiber glassing question.
I have another question. I put on a second coat of epoxy, scraped off all od the excess, and let cure for 24 hours. Then I pick it up and look at it, and it looks like it barely filled the weave. Did I remove too much?i would have thought it would have been a lot smoother. Do I try and skim it again? It was pretty heavy cloth for the float bottoms. Or do I fill it smooth with the primer?

RE: Fiber glassing question.
t is it normal for it to not fill all the way on the first (actually seconc ) coat? or is it the norm to have to add another coat to fill the weave?
