  • Plywood vs MDF

    I've seen many post they cut puzzles from plywood. Has anyone ever used MDF with a veneer instead? Any significant differences between these two I should be aware of?

    Just my opinions but...

    DUST - Cutting MDF produces an incredibly fine dust that is difficult to collect.
    MOISTURE - MDF likes to absorb moisture and swell so I'm not sure it is suitable for use when you are making locking pieces for puzzles.
    EDGE - I find that MDF has a tendency to edge chip much more easily than plywood.

      I agree with George on his points. MDF breaks rather easily and I would be afraid any mishandling would break off the interlocking tabs, creating a choking hazard...

        Thanks. I had seen MDF where I can get Baltic Birch and with the different veneers and appearance of a solid core was wondering if it would be a viable alternative to plywood. I'll take it as a no and stick with the plywoods.

        Thanks again.

          Hi

          I make lots of things with MDF and do not find it a problem all, especially when you are paiting it. I use a vacuum cleaner attached to my saw, the dust does not create much mess (I wear a mask for cutting everything). I have never had a problem with it breaking, I often have pieces break out of ply. As for swelling, I think you would have to immerse it in water and ply would't stand up to that either. I have not used veneered MDF. Go for it, I would if I had some local availability.

            I did the Tiger Butterfly a few years ago and used MDF for the backing. I ended up painting the MDF and in my opinion I liked it better than the plywood and I am not a good painter. No chips, No swelling I may have been lucky.

              This was discussed a month ago and people pointed out that MDF has formaldehyde in it. HDF / hardyboard does not however. I found HDF at Home Depot and/or Lowes but can't recall what it was called...hard board or some such thing. I did not buy any - only came in 4x8 sheets and decided to use plywood. I like the idea of MDF/HDF (for adults) though since people are used to that type of material for puzzles, and it should be flat - not warped like plywood.

                I just finished rebuilding my friends 2nd EX 21, This one was in much better shape than the first. No rusty bearings this time but I re-greased them anyway.
                I adjusted the front back motion and and the blade is also at 90 degrees to the table when using the locating pin.

                If it means the difference between cutting something and doing nothing, then go for it. It might not be the choice of most of us, but we aren't working under the same constraints as you. Hope it works out for you. Looking forward to a review, once you get a few miles on it.

                After totally over-thinking this, I have decided to go ahead with the Micro Mark Saw. It will enable me to do everything I can imagine in my limited space and budget.
                I thank everyone for offering advice, and I look forward to receiving more. As soon as I get it and set it up, I will post pictures...

                Figured it out. The photos were Live and I had to edit them. As you can see, we were quite lucky they didn’t come crashing down in a storm. The last picture was a 2 trunk tree. My son already split a truck load today.

                Next project, the roofer next week. Yippee....
