I just pruchased a Grizzly 1023SL table saw and I am going to build a outfeed table for it. I like the simplicity and the design of the one featured by the Wood Whisperer.

http://www.wonderhowto.com/how-to/video/how-to-build-an-outfeed-table-for-a-table-saw-219867/

He used 3/4” plywood but I was wondering if 3/4” MDF would be just as good. The reason I am considering MDF is that it is a bit cheaper than the nice cabinet grade plywood which is what I would build my outfeed table out of.

I’m just not sure if MDF is as strong as plywood….. Is it just as strong or maybe even strong in this application?

While we are at it, what are some of the pro’s and cons of MDF vs. Plywood?? -pockethole joinery in both? -strength as a table top? -span abilities? -some more?????

Thanks guys for your help!

A plus I could see for MDF is it is very slick…easy to slide stuff across as a catch table….a minus is it is VERY heavy…and does not hold screws well…so if you ever plan on adding things to your catch table and using it as a work table also….you would have to back it up. Also once you put a bad scratch in it…it does not have the same “Slick feel” it had before once it is sanded.

Mine is a simple design…just 4×4’s and plywood on casters (See shop pics)....but I have a 1/4” piece of hard board screwed to the top to make it slick as a catch table. The hard board also serves to protect the table as a sacrificial top that is easy to replace when it gets to worn out.

I have always used MDF, sprayed with a few coats of Lacquer, then rubbed with furniture polish. You’d be suprised at how well this works, besides saving you a load of cash. The only thing is you need to build a good sturdy frame for it. Have fun with your new toy.

I have a folded ping pong table. If I get bored with woodworking I can drop the blade move the fence and play.

I actually think that in this case, MDF might be a better fit – as it’s slicker ( esp. if you finish it with 2-3 coats of poly – it’s super smooth and resistant), and is more uniformed than cabinet grade plywood. MDF is strong enough for that purpose at that size.

I used mdf for mine, no finish and it works great, very slick and i made mine so I can flip the top when it gets damaged. So far no marks from running the stock over from the saw. http://lumberjocks.com/projects/14992
