Epoxy Resin Alternative / Substitute?

Hello!

I have a couple live mahogany slabs that have multiple cracks in them. They will be joined to create my dining room table. I am at the stage where I did a surface plane on all the pieces (with a router jig that worked excellent!), and now wish to reinforce all the cracks with epoxy (or another technique I'm not aware of to achieve the same result).

I have always heard Eco-Poxy is the best. Also the most expensive.

I'm sure this has been asked before, but are there any other solutions to reinforcing and/or filling those cracks?
Are there cheaper substitutes that can get the job done?
Are there any other completely different techniques that will achieve the same result?

I want to hear them all and learn what my options are.

Thanks,

Functionally you could put bowtie patches on the breaks to keep them from getting worse but as far as filling the void unless you want it wood colored epoxy is about the only product. If you want it to look like it has wood putty in it you can take bondo and add a universal color tint to it before adding hardener and use that to fill the cracks. You first need to stain a piece of scrap wood for a color sample and mix the color to match the stain, only a little less red. When you add hardener to the filler it adds the red color to the mix.

Thanks for the reply, Steve.

Is there any comparison in functionality between bowties and filling the gaps with epoxy? If I had to choose one or the other, which one is better from a functional stand-point?

PS - What are some recommended Epoxy products that will get the job done that is easily more affordable?

Functionally the bowties would be better. If there was sufficient wood movement the epoxy could let go but the bowties would only get tighter.

I don't work with epoxy enough to recommend a specific product.

Around the marine world, West System epoxy is generally considered the best. There is is used for everything from hull repair to woodworking.

The bowties are a mechanical fastener. They are shaped that way to provide resistance to further movement. Any adhesive like glue or epoxy is a part chemical, part physical bond which is very strong, but not as good as a mechanical attachment. Combine them both and you have the best of both worlds.

Amazon will have ratings for almost all the adhesives on the market. Check them out. Also some are only sold in commercial quantities, too much for smaller projects. A quart should work for your project. You'll need one quart of resin and 1 quart of hardener.


You have some serious grain mismatches using those planks. Colors are grains are completely different. I would see if you can find a center plank that more closely matches the others....

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
