I posted my trouble about a cloudy residue after wet sanding with penofin on my Koa table top in the finishing forum. So I re sanded from 80 thru 220. Re-oiled the top, and have been letting the penofin oil cure for the past week. The top and bottom were oiled and the wood has not been in the sun. I checked the table top today and it has cupped about 3/8”. Planing isn’t an option. Anyone have any ideas? It’s a natural form top roughly 30” wide by about roughly 40” long. It’s also about 1” thick.

turn it over , if you can ,get the convex side in some sun.. the top surface is drying faster than the bottom. It will reverse, just keep an eye on it as it can also reverse,

You might be able to pull out the cup when you attach to top.

Have your say...
