IMAC Dalton 300 ml build thread.

have you done any testing on how well the new glue will hold over the old glue joints. This is something I really do not know but it would be a concern of mine. My thought on this is the glue will soak into the wood for a bond. Now that it is dry it may not have a great surface to bond to. Just food for thought.

Great thought. I do not know and that never crossed my mind. You are totally correct. Most of this was glued with TITEBOND, so I am sure it is soaked in. The wood is porous, at 1st, but once we use that glue, it enters the pores and hardens. Hmmm. I will have to think about this some more.

This is something I am not familiar with. When I recovered my H9 Sukhoi I replaced some stringers. It was fairly easy because of the glue used. A heat gun and out. I was glad I replaced the new wood with hot glue because I accidently broke some pieces and it was an easy fix. I was thinking how much worse it might have been if I glued it in like I originally planned. Some ARF repairs I have seen done was done with epoxy but it definitely looks like a repair. Maybe some testing or a builder could chime in also.

Using wood glue I think you will be fine as it has a lot of surface bond as well. I would not trust CA though in that instance. I may be wrong but that's my opinion.

For best results you'll want to remove enough area of the wood you are bonding to to GE to clean (not glue soaked) wood. For stringer type repairs, simply cut them back and use a scarf joint (cut at an angle to increase glue surface area). For joint that you cannot remove the old glue use epoxy ( and I highly recommend Hysol) as it will create a very strong mechanical bond without the need to soak into the wood. Just make sure the joints are as tight as you can get them and if there is residual glue rough it up a bit with sandpaper to give the epoxy some tooth to bite into.

Your plane is totally repairable....it is just a matter of whether you will enjoy the task or not ( or save enough coin) to make it worthwhile to you. We all view thing differently....I love to build, but hate to repair. Also, you can do a great job and make everything very straight, but it will never be exactly like the undamaged aircraft and it will likely gain some weight in the process...doesn't have to be a deal killer and there's no reason the plane can't perform superbly again...but you can't make it perfect.

I actually broke my tail section and ended up getting the parts from Tony.

What about sanding down the balsa sheeting, replace the broken stringers or splice in new ones to the broken ones, and then re-sheeting the fuse?

 

[orthobird]

Awesome! That is exactly what I will do. Removing the sheeting is so easy, i had not idea. I am using a chisel. and it removes it like hot knife thru butter. Now all it needs is a final sanding. I will not be getting parts anytime soon, since Tony is preparing for his contest. So it may be over 1 month before I get them. In the meanwhile, i will repair the stabs, and sheet the turtledeck & the fin and one side of each wing.
