I’ve been working with rough lumber taken from school construction sites. Very dear to the architects/owners heart, but crummy lumber. Anyone have any great ideas for filling knot holes and cracks? This one is magnolia and cherry. Magnolia is a lot like poplar. It’s genetically similar?
Maybe epoxy?

If you plan to finish it with polyurethane or some other compatible finish you can use poly blended with sawdust to plug holes and cracks. I would suggest that you fill cracks with a filler that contrasts with your wood instead of trying to match it as it will probably look more natural. Epoxy all works well but I find poly to be easier and less messy. If you use hot hide glue that is even better as it is quicker. Another great crack filler is shellac sticks. You can buy a set with different colors and you just use a soldering iron to melt the color of choice into the knot or cracks. It cools really quick and is ready for sanding in a minute or so.

I have only tried the sawdust and epoxy/glue trick myself, but I have seen some amazing things done with crushed stone, crushed glass, sand, and metal filings. I will be trying crushed turquoise on a future project – just haven’t had the time to get to that stage yet.

Good luck and let us know what you decide.

Just beyond the epoxy is good old “Bondo’” fiberglass resin … As you play with this stuff, you will find that mixing with sawdust, sander dust, and key filings is just the start of the additives that you can use.
I have added stains to color it for effect … I have added sanding dust to colored resin and swirled it with a toothpick and made a knot that looked very real.
Takes some practice, so don’t start on your best piece.
It sands well and if need be you can cut it with wood working tools.

COFFEE GROUNDS WET, WITH CA GLUE
pack the grounds in tight and pour CA glue in the grounds
also you can use sawdust of red heart and other interesting woods.
Just my 2 cents

Thanks for the help. Not sure what I’ll try. Have you all noticed the trend toward using bad wood and charging more, alot more for it? Flooring seems to be the trend setter in this area.

I have noticed – it is not “bad” it is “distressed” or “aged” or “reclaimed” or “upcycled” or “ecologically friendly” or “green” or whatever the trendy term is at any particular time. It is all about the marketing now – take the lowest quality product you can find and describe it so that people think they are getting something special when they pay premium prices for it. (If this sounds a little cynical – it is because I spent 10 years in retail.)
Enjoy the rest of your weekend.
