I have a mango wood slab I am using as a tabletop for a bar outside.
One side has warped and sits proud of the base.
I was thinking of putting wood above and below and clamping it down to allow me to screw it to the tabletop but I thought someone may have a better idea.
See photos.
Hay @AntonT
Look you are right on the money I have same clamps = supercheap auto ? lol cheapies but good.
Those clamps will allow you to pull the wood down then screw the board from underneath I might use 6 to 8 screws each end and along middle.
A good bead of liquid nails super strength will act as a glue and filler the smaller gaps at the same time.
Leave set for 48 hours to a week fo max strength plus.
To clean up any liquid nail over flows use a clean old rag or chux and turps and wipe it off the under slab and metal frame where it squishes out.
Dirty rags use another.
Before you glue and screw use your clamps as a pre trial run to listen and make sure the timber will flex flat saftly . I think you know the signs before timber snaps We dont want that.
Some times it takes gradual clamp tightening to gradually shape wood to a new shape or flat.
Can I suggest put a block wood under the clamp foot on the wood plank top to spread clamp force out. Underneath you nailed it with the frame block to stop marks on the frame.
Nice work
Final phase.
And so I didn't skimp on the screws and used a heap of liquid nails for
the final clamping.
Screws are wafer head 14g x 70mm as seen in photos.
Will leave clamped for a week and then see how it goes. Will add brackets if I have to.
Hi @AntonT
That project looks great top marks for you hard work and problem solving. Its flatter than a pan cake in photo.
Its a nateral great looking piece of timber you know that so if there is any slight bows left well that adds to the nateral charm .
If you wanted 90 degree dead flat you would have gone DAR timber
If that board pops of I will eat my shirt lol by the way.
I suspect you beat me to the punch on my next sentence.
I dont know if you still have those liquid nail glue dags. But if you do trim them with a thin blade close to the metal should tidy it up a lot.
Great project photos too.
Regards Tony
Thank you Tony.
The slight bows or imperfections are fine with me. It was the major warp that I hated. If it stays like this when the clamps go I'll be really happy with the result.
To be sure I knocked on it and said "that's not going anywhere!".
Yes I'll definitely tidy up the liquid nails although I doubt anyone will see them anyway.
Hi @AntonT
You are 100% right no one will notice the liquid nails ever.
But you will.
Just go that tiny little bit extra so its done. Sorry here I am imparting my work ethic on your projects not cool so feel free to do your own thing.
I guess my personal aim is to do the best job possible within reason and that way you can enjoy the fruits of your works afterwards and not have any post nagging thoughts of would-a could-a should-a.
Thats a great glue curing time by the way why rush it . The clamps make gluing and screwing so much more easy.
I'm pleased to say it's come up really well. Clamps off and holding fin
e. I'll use a little monument paint to cover up the liquid nails mess I couldn't get off at some point.
There is now just a very minor natural dip which is perfectly fine by me.
Nice spot to watch the sunrise with a coffee.
Thanks everyone for the great advice.
