Joining warped boards

You can never pet boards perfectly level when you glue them. Some sanding or scraping is always required.

You could try biscuits since the biscuit jointer would reference the top surface when making the cuts.

Gary, that makes me feel better about some of my own work. I thought I was just not good at aligning my work. That still may be the case, but it still helps.

Gary,

First thanks for the response. I don’t own a biscuit joiner, but would not be opposed to buying one. I have seen some comments about the strength of biscuits, would a regular biscuit have sufficent strength to hold the two 7/8” thick boards in alignment? Would dowelling with a centering jig be another option?

Coming from the kitchen countertop industry, we seam two pieces together all the time. There are different techniques for different materials, but your best bet is the joint connectors.

you spread glue on the mating surface, then tighten the bolt, this connector gives you enough play to move the seam before the glue sets. It will be under the table so the ugly hardware will not be seen. It’s not the best solution, but it is a proven systems in millions on homes with formica tops.

Thanks Thuan.

I am most concerned with keeping the top and bottom board surfaces aligned. So a biscuit or some mechanical device that will keep the top and bottom board surfaces even may work best for my project.

You can also spline them. A spline or slotting bit would be cheaper than a biscuit joiner and stronger.

tenontim – has a point I was just coming back to mention. A slot cutting bit in a router would work
great.

If I can agree…Not needed said at this point, but that’s what I would have chosen to do.

Thanks everyone for the suggestions and options.

A row of dowels along the seam should line them up also .

make sure that they are drilled accurately all from the same edge of the two boards.

Thanks Karson.

I am considering getting a dowel jig or a PC biscuit joiner. I would hate to get a dowel jig and use it once only, but this also goes for a biscuit joiner. I am thinking, I may end up getting more out of a joiner. But really don’t know.

Appreciate your suggestion.
