Can I make wood putty?

Can I make wood putty?

I know the flour and CA trick, But this big dent is in the leading edge of a finished wing, CA would probably get where I don't want it.(doesn't it always?)..... is there a paintable alternative?

Thank you in advance!

I agree with the spackle if its just a surface dent.( i use it all the time myself ) I'm sure you have heard of the water & heat method to raise the wood as another way to remove a slight dent.Another way,if its too deep,is that you may have to cut into the wood and replace it with new wood & then sand it to the desired shape. When i was a kid i made putty with balsa dust & elmers white glue. It was difficult to sand since it was harder than the surrounding wood, but worked in a pinch.....Gene

It depends on the area you're planning to fill, how thick the filler will be (if it's really thick, use balsa as a filler), and what your filling will be covered with. I've used spackling (regular and light weight), Elmer's wood filler, epoxy and micro-balloons, and balsa sawdust/sanding dust or talcum powder mixed with carpenters glue. I've stayed away from anything mixed with CA since the CA cures very hard and makes it difficult to sand (I have seen dirt mixed with CA for a field repair).

if it's structural, I use epoxy and dalsa sandings!

Whiskey, where I'm gonna fine dat dalsa sand? LOL

Thank you, Gene. I'm old enough where I'm forgetting some of the tricks I used to know...crap.

This ding is on the leading edge and you could hide a pencil in it. I thought of lightweight Spackle right away, but I'm worried it will not be durable enough for every day (flight) handling. Thanks agin

If its that big... just cut a chunk of balsa wood down and glue it in.. sand it... throw some lightweigt spackle in there.. and just final sand it.

If wood was in the ding before.. wood would (punn intended)..be best to put back in there. Me thinks so... but thats just me.

If it's the shape of a pencil too how about cutting a piece of dowl and epoxy that in place? Then mix some sawdust and epoxy to fill the small gaps left. I would have to take a piece of balsa and a sanding drum to make the dust though. I don't build from kits( or at least haven't yet) so I don't have any dust on hand.

The "Old Man" here -just passing through...I use lightweight spackle on minor dings, too big to swell back to shape..Fill it and sand it to final finish, then flood it with thin C/A.
You won't 'ding' it there again.

The simplest things are genius at times. I know the old baking soda and CA trick but it gets so hard you can't shape it afterwards....... your idea to shape the lt wt Spackle (which I deemed too soft) and then flood it with CA is genius to me. Yet obvious! I like it. Thank you. I shall try that on a sample to see how it goes.
