ca glue question
Mar 2nd, 2021 at 4:52pm
 
Just a quick question about ca glue. I never really had to use it but I did recently. I used the method of mixing sanding dust with it to fill a couple small holes. What a disaster. I had to sand forever trying to get the glue to not be noticed. Is this only used for small cracks? Thanks for any suggestions.

I would say yes.
Others use it much more than I do but I try to keep it to small cracks and if I'm using saw dust, the finer the better.

First, Welcome
Second: What do you consider a small hole?
To fill voids with CA, recommend to seal wood around the void to prevent CA from staining the surrounding wood. Next fill void with a filler (wood dust, metal flake(fine) coffee grounds, ETC.) then add the CA.

I use a thin coat of 2# cut shellac around the area I am going to fill with CA and filler.

It's been a minute since I've checked this. Thanks for the welcome Glen. I would say very fine cracks or small pieces of tear out is what I was trying to fill. So I'm not sure coating hairline cracks is an option. Maybe I just was using it wrong. I was using medium ca glue maybe the thickness is the issue? Thank you all for the replies

You might consider experimenting on one or two pieces of scrap wood, perhaps one light colored like maple or poplar and the other darker wood.

Make a teaspoon or more of fine sanding dust from each using 220 grit paper.

Simulate cracks with a utility knife and holes with perhaps 1/16" and 1/4" drill bits 3/16" deep. 

Make a short line of CA on the surface of each board to see if the wood is noticeably stained.  Fill the scratches and holes with sanding dust as already described, wet with CA, sand after the glue sets, and evaluate.

I only use CA on fine rim cracks that appear as I am (once) turning a bowl.  It is fast and convenient, but I don't like the appearance of the cured CA.  To fill worm holes and other defects I use 5 minute or "one hour" Devcon two part epoxy from a local hardware store tinted with dried pigments (fresco powders?), the most commonly used colors being raw and burnt umber I think.  It is a much slower process but I prefer the result.

Tear out should be sanded out not filled. Very fine cracks can be filled without a filler. If needing a filler, pack the crack with dust, add THIN CA, repeat as necessary. A good way to prevent the CA from staining the wood is to coat the piece with a finish(WOP) first.

It is difficult if not impossible to make a crack invisible.  I find it more rewarding to go for increased contrast rather than try to hide the crack.   Dark walnut dust is good for this.  Coffee grounds too, but it is difficult to get the grounds fine enough.   I have also used a rotary tool to widen the cracks and then insert turquoise chips.  Another trick is to wet sand with CA glue.  The sand paper only lasts for a few seconds before it clogs up, but it works pretty well for fine cracks.
