So building my cnc table and I have the frame done. I am considering options for the top. Was planning on 3/4 mdf just like most but I actually have a 3/4 Melamine 49x97 sheet sitting in my garage for last 3 years. Is there an issue using this for the top for my 1F to attach to then placing my 32…

My table design, will add corner bracing once i get top on so the feet of the 1F sit on solid wood, then build an enclosure since this is built in my basement in our furnace storage room (only space left for me) [Screenshot - 11_1_2021 , 3_18_33 PM] Shop vac and dustopper will sit under the machine…

I’m using a combination of baltic birch plywood (3/4 in) with a MDF (1 in) as the waste board. From my perspective, as long as you have a solid (no flex), straight/flat foundation I would think your approach works. The major difference will be when you start cutting into the waste board. In my o…

[image] Ken: The major difference will be when you start cutting into the waste board. In my opinion and experience, MDF holds up nicer than melamine If he cuts into the Melamine table top through his MDF spoil board he’s gonna have more to worry about than the quality of the cuts and how Mel…

Like others have said, neither. MDF isn’t very strong but it does make for a good spoilboard. I used Advantech subfloor. It’s an engineered product that handles moisture and I’ve found the thickness to be more consistent than plywood. Baltic birch would also make for a good top. The top isn’t g…

MDF with a gallon or two of Danish (or Tung) Oil makes a good, if immensely heavy, a workbench that can take a beating. I made my first MDF topped workbench before the internet was a thing. It is still going strong.

@AndyP Agreed! I have an MDF out-feed table / workbench behind my table saw, finished in Danish Oil, that has held up great for almost 20 years. @CrazieBird - I would think the Melamine top would be just fine. Your frame has all the strength/stablity needed. I have MDF on mine - can’t see how mela…

Do you recommend 1 3/4" sheet or 2 stacked together?

Generally speaking, more mass is better. Also, neither melamine (particle board) nor mfd have much structural strength so need support. If your table (or cabinet) is straight and square with adequate supports in areas of span, you may find a single layer is sufficient though.
