Default Suggest a bit please

A forgotten teapot went dry and caused a formica counter top to bubble up. I'm hoping to plane it flat with a sled but am wondering which particular bit would best suit planing formica or arborite. Any suggstions would be appreciated

Not a good idea. Formica is a clear layer of laminate on top of a patterned layed of paper, on top of plain layers of paper, all soaked with a phenolic resin. Trying to plane the bubble down will cut into the un-patterned layers. You could try drilling a hole from the bottom up into the air pocket but it is a very slow process, best finished by hand that is very tricky to do without drilling through the laminate. If you can make it work, squirt some glue through from the bottom and put some weight on the laminate until the glue dries.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Thanks Cherryville but the problem is bigger than that - the size of the teapot - about 5" in diameter. I want to just level off the laminate and put new laminate over top. I'm just wondering if I need a special bit for laminate or will any planing bit do.

Are you talking about the whole countertop or just the damaged area?

I really don't think using a router for this job is going to work, not least because the router will not like the underlying adhesive and will soon get its cutting edges mired in it.

Whether you were thinking of removing all the formica this way, or just a piece of it to drop in a matching new piece, I don't think it would work. If someone else has managed it, it would be interesting to read about it.

Cheers

Peter

Thanks for the welcome James. To be precise with my problem and my intentions, the countertop is originally a formica sheet glued to a plywood base - this house was built during the 70's and that was the style back then. The heat from the teapot caused the countertop to swell over a 5" diameter area. I would like to somehow grind down the "swell" (a maximum of 1/4" in height) to eliminate the rise so that I get a smooth level surface on which I will apply a new sheet of formica the entire length of the counter. I'll run up and take a picture tomorrow so it's clearer what I'm talking about.

HI Lynda

I will suggest doing it the inlay way, once you get the spot down insert the patch ,than cover the repair with a new full sheet...if you are real lucky you can find the same "formica" ..Or you can put your own design in your counter top ..like a tea pot or insert a ceramic tile for a hot plate thing..just need to make a template,,see video below..

Thanks Bob. I gather from all the answers, I can use any flatbottomed bit to do the job, whether by inlay or otherwise. First I must get the raised spot down to either the same height as the rest of the formica or down to the plywood. Either way, I must have a flat surface. I think it would be easiest to do an inlay. Even if it doesn't fit exactly, so long as the difference allows the new sheet to lay flat and not dip or rise at that point. I already have the formica and intend to update the entire counter. Will keep you all informed how it works out. Thanks

Default Burned countertop

Here's a picture of the damaged area. The center is raised about 1/4". I gather I should rig up some sort of a ski system to try and plan it down to an even height overall. If that doesn't give me a flat even surface, I'll then try cutting the secton out and doing a sort of inlay.
