I'm jumping back into woodworking specifically to learn more about resin tables and similar projects. I'm searched all the woodworking forums that have come up on google but I haven't seen any forums specifically dedicated to resin topics. Is there something like this around, maybe sponsored by one of the resin suppliers that I haven't stumbled upon yet? I'd hate to keep bothering general woodworking forums with resin questions.
Also, earlier in my research I found a supplier that had a page of many of the tools you need when working with resin tables and one of those was a 3" 4 blade router bit that planed a surface. For the life of me I can't find that supplier's page again. Does this sound familiar to anyone? It's not Black Forest or Stone Coat Countertop. If not, would anyone have a good suggestion for a similar router bit? The one listed on that particular supplier's page was about $100.
The bit in question is known as a spoilboard surfacing bit. All the major industrial bit manufacturers will have one. They are recommended to be used only in a cnc spindle though.
$100 for anything other than a simpe 2 flute brazed carbide tool is cheap.
With regards to your resin pursuit I would caution you to #1 that you may be coming in towards the tail end of a trend but of course who knows how close to the tail. And #2 I have no way to quantify it but always keep an eye out, but I have a feeling your going to see a lot of resin tables in the landfill in the not too distant future but I guess the upside is it fueled an economy for a while.
There are so many (to me) flawed concepts with regards to the entire process, material, interface between wood/metal/resin, and more, that I cant believe there arent already many many failed items out there that incorporated the process. No different than the myriad of posts and questions on the sites with regards to the problems of wood movement in conventional woodworking.
I choose to leave that stuff to the garage shop guys who seem to be able to escape liability or to the shops that seem to have clientele that will pay for the most stable material that may still fail but the maker is surely covered in their contract and the client likely has enough money that when a 20K table goes south in a few years they just commission another.
I'd really love to hear how those river tables handle wood movement after several seasons. There has to be a lot of partially dried slabs used, not helping things one bit. The second thing is how careful owners are with preventing scratches in the resin. I read a post from a slab seller who has had to surface a lot of river tables. He claims that builders pour the resin and are not careful to control the resin that runs under the table during pouring. He says that sets up an issue with the resin cure and actually pulls the table out of flat. Personally, I hate the tables!
We jumped on the slab and river tables as quick as we could. All we do is flatten them on the cnc. Most builders do not listen to reason and we end up flatten the same project for same costumers over and over again. We used to try to explain the problems with their building methods but they do not listen. Works out great for us...they keep bringing them back for more cnc work.
I would agree with Mark, id say we're on the tail end of this wave ( and I cant wait for it!!) I hope it all goes with the " Live Edge"/ "Slab Table" fad too. You can tell its starting to reach its peak when Lowes is selling "slabs" for $100 down the main drags of the store. Perhaps when all this nonsense is over we'll be able to buy wood with bark on it for less then 1k, the guys selling wood right now are printing money!!
