lost foam glue
« on: July 29, 2015, 12:59:23 PM »

 Somewhere I read that you can glue balsa to foam using white/yellow glue, but the memory bank is low on cash so I don't remember all the details..
 So can anybody refresh my memory??

Yes, white glue and yellow glue work well.  You want to make sure that you give things time for the moisture to get out, though -- don't assembly in the morning and paint that evening or you'll have a heavy & weak join.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

If you are applying wood to a foam wing use Z poxy and wipe it all off. Weight it in the cradle. You will think there is not enough glue to hold it but it will.

Robert,

Watched the video. I have some foam I'll be sheeting.

Hair spray. Did I miss where you explained it's use? Or what happens when it isn't used?

Good Morning Charles;

  Robert of course can confirm, but my recollection is that a light coating of hairspray is applied on the side of the sheeting which is to be attached to the cores before the epoxy is applied.  It help minimize the amount of resin which is absorbed into the sheeting...

Dave,

Thanks for the reply. Even though I seen Robert do it, I'm afraid to do it that way.  n~

Seeing is believing and Robert does know his stuff.

I'm wondering what little weight is necessary to still pull it off? The foam I'm sheeting has no cores.

Is Z Poxy just Z Poxy? Or is it 5 min, 45 min, 24 hr?

Thanks

Charles;

  Z-poxy is Zap Products name for their finishing resin.  They also offer 'traditional' epoxies with varying cure times...  According to the manufacturer, it has a 20 - 30 minute working time, and a cure time of 3 hours.

Dave,

Thanks for the reply.

Robert left his overnight?

What's the point of that if it cures in 3 hours?  n~

Almost all epoxies take 24 hours for fullcure.
