How to rubberized sanding table top1/31
Hi all !!
Anyone can advise what to buy, I intend to build my own downdraft sanding table and wish to rubberize the « perforated » top !??
Have you considered using cork as opposed to rubber ? If you have your mind set on rubber type of material, try those 3'X3'X1/4" mats you can get at an Automotive FLAPS. They usually come in sets of 4 or 5 and hook together like a puzzle.
Tks Robert, but yes I've tried, simply not durable, maybe for hobby, but for a shop ! !
On a side note, you can get rolls of cork 24"/ to 36" wide and up to 1/4 " thick. Its pretty beefy. Just a thought.
Spray on bed liner
check out Plasti Dip. I think you can buy it in gallons at big box stores.
Black rubber sheet is available from koi pond dealers. It is about .100" thick and comes in large sheets and is inexpensive. How you put it down and put in the holes, I'm no help.
What David's referring to is EPDM rubber membrane. It's used for pond liners and low slope flat roofs. Firestone warranties their membrane when used with some of the most noxious adhesive I've ever been exposed to...I've installed it on several roofs. I assume regular contact cement would hold fine. While it's easy to cut with scissors or a sharp knife, boring holes is a little different. If adhered first to a solid substrate a sharp hole saw bit would probably cut through no problem, but the edges may or may not be clean. A sharp hole punch would probably be necessary for clean edges although I can't imagine it would matter too much.
I use a rubber mat with holes supplied by Denray for polishing stainless on my metal downdraft table. It's a few bucks per sq/ft and can be cut to any size. The rubber is more rigid than EPDM if that's a concern.
You might also search for rubber flooring mats, there's tons of options from foam to rubber in different thicknesses and densities.
If you are building it, go with the rubber membrane. I've tried plasti-dip, vehicle undercoating, aerosol rubberized paint, roll on flex seal. The best is to just use the membrane and adhere it to a good sheet of plywood that has your holes already milled into it. After that you can drill a hole through the membrane and use a flush trim bit to match the membrane to the holes underneath. Its messy, but it works and you won't wear one out of years and years.
