Hi everyone; I have a parota slab that I am going to be turning into a dining table and a coffee table or a couple end tables.

The base i want to make with metal tubing, probably 1×3 and have the bottom fourth of it with parota and the stringer. My question is, will the parota be hard enough to handle the weight. They will be U shaped legs, the table top will be 42×80.

Second question is for leg spacing, and I’m hoping for some input. How narrow should I make the legs? (I thought about Have them all the way to the edge but, then a chair can’t go in.)
and for spacing I was thinking 14-16inches in from the ends of the table. Plan is 2 chairs on both sides and one on each end. But to have enough space for another two. 8 would be tiight though!!

Any input would be greatly appreciated!!

The thicker the slab the less likely it will sag up to a point. I would think you could determine that since you have the wood. Test it out.
As far as designs go do whatever looks good to you there’s no laws or rules.
Did you get the wood from Exotic and tropical woods of Latin America in Carlsbad.
They nice stuff there.

Good Luck

Bought Guanacaste slabs from TEH. Really pretty colors.

Surprisingly, not nearly as hard as most exotic woods, Janka value is only 470.

Here is ranked Janka list:
https://en.wikipedia.org/wiki/Janka_hardness_test

As far as weight loading and support, would treat it more like poplar (540), western white pine (420), or even basswood (410). Nothing wrong with soft-wood slab tables, just be sure to support the top properly for your thickness and length.
For 8/4 7’x16’ long executive conference room table using Guanacaste slabs I worked on; had to weld up a 1-1/2” square tube support frame with legs every ~4’ to prevent sag (especially when folks decided to sit on table top). It moaned/creaked just like a overloaded picnic table without added support legs.

Probably have less issues in your house, well – unless you kids climb on furniture when no one is looking?
Suggest you do what we did: use some sand bags, and/or some beer drinking buddies; to simulate weight loading and check for movement before finishing. There is also the sagulator calculator.

PS – Suggest using a hard top coat (poly or conversion varnish) if you have kids in your house.
Only took couple months for corporate laptops to scratch/dent the wood with nice oil finish requested. Had to return top back to shop, sand it down, and spray 3 costs of 2K industrial poly to harden the surface. Was a layer of ‘plastic’ commonly found on countertops in a bar, but was only way to keep it looking nice with a staff full of wood abusers.

Best Luck!

Thank you both for your input! I guess I didn’t reply a few weeks ago when these came up.

Have your say...
