Topic tags/keywords: mobile base plywood drill press

Quick and, hopefully, painless question: For a 180 lb drill press—and just in general—is there an advantage to using a 3/4 hardwood plywood or a standard ACX sanded 3/4 piece of ply on the mobile base (it’s nested into a portamate)?

For most shop cabinetry—is there similarly a real advantage for most use cases? I’ve just been wondering. I’m assuming not on all counts—more of an aesthetics thing than strength and the pine should be fine in most cases.

Thx crew.

If you’re talking about how much weight you can support then even if there is a difference it wouldn’t matter with only 180 lbs. 3/4” plywood is incredibly strong, so unless you want your shop cabinets to look great, there is no reason to use anything else.

For support of a tool, such as a drill press on a rolling base I have often used CDX Plywood, low cost, and the 3/4” stuff often is supporting major roles in the houses we live in, so it’s plenty up to the job of holding up 180#. Generally for better wear, and less chance of delamination I mop on some Poly pre use, and allow that to dry well. Keep the higher cost stuff for something upright you will be looking at, like a cabinet.

I have a machine that weighs 595# sitting on a plywood base. If you build it right, plywood can support an incredible amount of weight. I would finish it with a shellac sealer and any finish you want, like paint or a stain.

Thanks for confirming guys. You guys are the bee’s knees. It’s nice to put that nagging thought to bed. Most of what I have been using ply for is shop furniture. And although I like them to look clean (nothing like a crisp looking shop to elevate the mood—kind of like a suit, though I dislike suits I do feel classy in them) I’m perfectly willing to forgo aesthetics most of the time.
