I have some well seasoned Cherryblanks. I have turned 1 bowl with it and ii has several small cracks, I would like to try my hand at filling these cracks. I gather the approved method is 2 part coloured apply??? The question is, what type of colouring? I have seen several bowls with a bright metallic blue that I thought would look kinda sharp. Any suggestions would be great. Thank you.

i’m assuming that you’re talking about coloring a 2 part epoxy and filling in the cracks, while this method works sometimes it’s usually done with acrylic as it works better. regular epoxy can swell and cause worse problems but there are items you can use, things such as pentacryl which is a wood stabilizer, works best in a vacuum chamber but that is not completely necessary in this case. everybody will tell you a dozen diff ways to do it, what I would suggest is gather a few types of epoxy, shave some pieces of tool box plastic (these are usually brightly colored) or other colored plastic shavings, dice them up very fine and mix with different types of epoxy and try it on different blanks and see what works best in your case.

+1 for InLace. I have not used it for turning but it works well as an inlay.

I have mixed feelings on filling cracks. Have use saw dust and coffee crowns when would not detract from the piece to fill small surface cracks. On some turnings have just filled small surface cracks with film finish and got away with it.

While like some contrasting inlays on a bowl. Not big fan of filling cracks with those materials (metal shavings, colored plastic & stone), because just highlights imperfections.

Have seen people use dyed two part epoxies which blended well and some that just highlighted imperfections. People have used wood stains or dyes mixed with epoxy so hard to recommend one over the other.

Personal experience taught me learning curve, time and effort to getting a piece exactly right pretty steep. Depending upon wood will either paint or throw the piece in garbage or firewood bin when things don’t work out.

Just give it a try and let us know how you make out.

Thank you for the response gents. Thanks for the link Art. Thant’s pretty much what I was looking for. I hate it when I don’t proof read.

- cdaniels

I’ve never seen epoxy swell when curing, and use it all the time to fill cracks/voids. Sometimes using just neat epoxy, sometimes with fillers such as sawdust, coffee and other various materials depending on the project. Maybe it’s just the epoxy I use (West Systems), I dunno.

I actually did one just a couple days ago. I cut a bunch of oak slabs from a downed tree several years ago and left them to dry in the shed. They all cracked to some degree, some more than others. Once the cracks were filled with epoxy though, they turn beautifully. Here is a handwheel I just turned for my planer, sitting on top of a similar slab that it was turned from. You can see the crack in the handwheel that has been filled with epoxy/sawdust (it’s just above where the crack in the slab is).

Cheers,
Brad

PS: If you are going to mix a filler in with the epoxy… make the batch neat and apply that to the crack first, so it coats and absorbs into the exposed wood surface. Then mix your filler in with the remaining epoxy and use that to fill the rest of the crack.

I’ve used sawdust & superglue with some success. Be aware that no matter how lightly colored the sawdust, it WILL dry darker than whatever you’re putting it on.
