aviator_edb Posted December 4, 2009 Share Posted December 4, 2009 I've been really picking up steam on chapter 4 and only have the front side of the IP, the landing gear bulkheads and firewall to do. I have a new question. On some of the layups, specifically f-22, 28 and the IP, I had a helluva time keeping excess expoxy from running off and then under the foam. For F-22 and 28 there was only a bit and I easily sanded it off but on the IP I've got a spot that's about 9 sq. in. Do I really need to get that off or can I just rough it properly with 30grit and glass over it? as usual, thanks for any input. Quote Link to comment Share on other sites More sharing options...
longezdave Posted December 4, 2009 Share Posted December 4, 2009 I say just knock off any bump it may have made and rough it up and glass over it. Build on as Steve would say. Quote Dave Adams Long EZ N83DT Race 83 Link to comment Share on other sites More sharing options...

Just get out your FEIN with a sanding head (40 grit), knock off the extra epoxy in a heartbeat. and the resulting surface will be great for further bonding.

TMann Posted December 4, 2009 Share Posted December 4, 2009 I hardshell both sides prior to glassing. End of problem. Foam that has not been sealed with micro can wick up a lot of epozy adding weight. Think of the micro-slurry as you would sanding sealer.

Big Steve Posted December 4, 2009 Share Posted December 4, 2009 I hardshell both sides prior to glassing. End of problem. This is not an approved method of building. I have never done it so proceed at your own risk. If you are slopping on that much resin maybe you need to slow down and be more careful. I like to use my brush and stiple around the edges so I dont have to squeege loads of epoxy off the edges which causes this problem. But like others have said it is no big deal sand it smooth and yes it is comming Build on STeve Quote Steve Harmon Lovin Life in Idaho Cozy IV Plans #1466 N232CZ http://websites.expercraft.com/bigsteve/ Working on Chapter 19,21 Link to comment Share on other sites More sharing options...

Think of the micro-slurry as you would sanding sealer. hard shell all the parts? you mite end up with a heavy plane that you wont like to fly, have you ever grabed on to the side of a bulk head and tryed to remove the glass ? you mite find its as easy as peep ply.

TMann Posted December 5, 2009 Share Posted December 5, 2009 This is not an approved method of building. This has been discussed at length already. I have it from an engineer at scaled that it's not an issue ........ but we digress.

Clean???? Been there, done that I'm still pulling the resultant airborne fiber and epoxy dust out of my personal glass. (I even used a vacuum system directly over the router) a better way is to layup as you would for routing, however use a sharpie to mark actual size and shape or cut out template and glue on cured glass and cut out with metal cutting band saw. The band will last for quite a while, however after the first cut, the blade will be unable to cut metal well. Quote I Canardly contain myself!

Derek449 Posted January 3, 2010 Share Posted January 3, 2010 I had the same problem, and sanding worked. But what about on the glassed sides. I had a bit on the inst panel glassed underside. How can I remove that and keep the nice glassed finish? Thanks, Derek Lewis Quote Cozy MK IV Chapter 5 Link to comment Share on other sites More sharing options...
