I am working on a fluted handle for a dagger I'm doing and i am using a chunk of stabilized redwood burl. it has a knot and a bunch of checks that need to be filled. I will say up fount that i like the knot and checks, I think it gives it a very cool look. now that being the case i don't want to fill them with sawdust and supper glue. so I'm just using a thick super glue and filling all the voids. but is there a supper glue that drys faster then normal super glue. or is there something else that works better. I have the block turned down to about 1.2" and have it drying after a coat of super glue but some of the voids are large and the glue does not stay in the void. that's why i wonder if there is a super glue that sets up super fast in the air. thanks everyone.
 
Here's what I'd do for gunstocks with the same problem,

1. Make a bunch of sawdust from the wood scraps. Fine.
2. Mix the wood with some Acraglas epoxy until it gets the "bread dough" thickness.
3. Fill hole with mix.
4. Use business card to scrap off excess mix.
5. Finish as normal when hard 24-48 hours.

I found Acraglas mix like this make an almost seamless repair, and it will take stains and dyes too.

ya i have done that with saw dust but i still want to see the checks. the wood has a lot of varying color so i want to embrace the flaws and work with the,. i have been thinking of using Polyester Casting Resin found at craft stores.
 
We make a lot of pieces where we draw attention to the cracks instead of hiding them. If you really want to draw attention to them, here is what we have done.
Paint the inside of the cracks with flat black paint. Sand away whatever you get on the surface. Then mix some 5 minute epoxy and blob it into the cracks. Have a cup of coffee and fill any low spots with more epoxy. Then sand and finish as usual. For bigger than hairline checks epoxy always looks better than CA glue whether you use it as is or mix sanding dust or....? into it. The 5 minute stuff doesn't slow you down and you know if you need to apply more right away.
I hope this helps.

Super glue (cyanoacrylic, CA) can be accelerated by application of a basic such as spray cleaners which contain ammonia (Windex), it only takes a mist so don't over do it. You might want to try a few test runs on a piece of scrap. Another method is to fill the void with baking soda then saturate it with super thin CA glue. it sets up in about two seconds so don't be slow!!

you can mix super glue with corn starch and it takes about 5 min to set up but when it does its BAM hard. its cool to use when you need a supperglue putty that you can work with for a few min then have it set hard.
 
well i got the fluting done, i will post a picture later tonight when i get home so you can see my first attempt at this crazy thing.
