    Ever hear of 1/4" MDF?

    Well, I hadn't, until today at HD that is. I was very pleased as I have a couple of ideas for this stuff. Neat! especially since I can't seem to find 1/4" pressed board around my house.

    Have seen the hardboard and pressed board but never MDF below 1/2" Good pattern stuff I bet.

      HD has had it around here

      HD has had it around here as long as I can remember. I don't recall if it comes in 4x8, but I buy the 2x4. Ken is right, it is perfect for making patterns.

          Yes it's 2x4 but that's fine with me. I can tote it in my sedan.

            Been using 1/4"/6mm MDF for YEARS! (Yes, Loring; I know 1/4"=6.35mm)

            In fact, in Oz, the 6mm MDF is a poofteenth larger - maybe moisture?
            I use a 1/4" spiral bit to rout dados for it and the fit (with glue) is perfect.
            Downunder ... 1" = 25.4mm

              We have 6mm in Japan too. Nice stuff and great for special projects. Mac, it works great with an Impact Driver too.

                In the UK, MDF is available in

                4mm
                6mm
                9mm
                12mm
                15mm
                18mm
                25mm.

                All come in 1220mm x 2440mm (4' x 8') sheets.

                Additionally, you can get 18mm (3/4") in

                1220mm x 3050mm (4' x 10')
                1525mm x 3050mm (5' x 10').

                Spoilt for choice, really!

                  That's a lot of choices you've got Ray, but 5'x10' sheets of ¾" MDF? Do they supply a forklift to move it around?

                    Leehljp what impact driver? See I'm already over it. And Rod can I ask you why a spiral bit and not just a regular say 1/4" straight bit?

                      The spiral "slices" the fibres more cleanly than the "scrape" from a straight bit.

                      And I meant to say before - in Oz a lot of use is made of 3mm (1/8") MDF - eg melamine one side for drawer bottoms. I use it often for full size layout plans.

                        Yes, Bob, a 5' x 10' board of 3/4" MDF weighs almost 140 lbs. so they are a bit of a swine to handle. On the few occasions I've had to use such a sheet, because of the length required, I got my supplier to cut it roughly to width for me first, but there's no way I'd want to try and handle a full sheet on the BT3!

                        Ray.

                          Thanks for the reply Rod. I see. Boy there is just a lot to learn about bits but I learning. Thanks again.

                            Might be a silly question, but isn't hardboard basically the same as MDF.
                            The amount of dust is sure similar.

                              Very different stuff, Brian.

                              In Oz: hardboard = masonite = nearly black in color. Dimpled on one side, flat on the other. Filthy stuff to work with. Also sold here as pegboard sheets. 6mm thick only

                              MDF = Medium Density Fiberboard = differing "pale" shades of beige.
                              Multiple thicknesses available. OK to work with "sensible" DC - I love it!
                              Downunder ... 1" = 25.4mm
