  • how I make a grill.

    thought i would share the steps i take to make a grill.
    this one is for a new center channel speaker im working on.
    i have some nice 3/8 mdf so thats what i use.
    step one is to size and shape.


    then i align the grill with the speaker and drill very small holes so they will align when both parts have magnets.

    then enlarge the holes to except the magnets.

    then i glue the magnets in with construction adheisive. the magnets will not stay on their own so i dump a healthy pile of sawdust from my sander so a board wont stick.



    next some primer and flat black.
    then we head for the house. cut a good chunck of grill cloth, warm up the glue gun and iron.

    just work your way around the grill. sides, ends and in between. dont worry about neatness at this point, just get the cloth glued in place for now.

    trim up all the excess material.

    time to get out mama's iron. should be nice and hot. you'll alson need a tool like a screwdriver or somthing to manipulate the hot cloth. the glue at this poing is very lumpy, so use the iron to flatten it out. you'll need to hold it in place while it cools. in the corners just hold it flat as it cools.
    i had some little rubber feet so i put them on the grill magnets so they would not break the paint on the speaker. i have also used little felt pads. using two magnets has a very strong hold.
    these are meant to match my mains.

    I thought using the iron was my idea... I guess geniuses do think alike! Good pics and write-up by the way.

      Thanks for sharing your method. It reminds me that it is not to much trouble to make grills and they can vastly improve a speakers appearance. Hope my wife never sees this, I'll be making a lot of grills if she does. ;)

        thanks. grandkids or cats have never bothered my grill. i suspect that would not be true without.
        just wanted guys that have never tried to see how simple they are.

            After trying a lot of different types, I found a great pair of scissors (snips) at the craft store for cutting the excess grill cloth away from the frame. Very easy to use, especially if you have all thumbs, like me. :o

              The mains look great painted, very smooth. Speaking of smooth, I noticed the seam filler on your center, what do you use? Do you have to belt sand it or is it soft enough to finish sand?

                thanks brew, cali.
                its acryl green spot putty. i learned about it here. dries very quickly and sands fast. the mains were painted by a pro in a pro booth. the cc has a bunch of primer and several coats of paint and a bunch of sanding. the final coat is fusion paint. i have seen it mentioned many times by wolf but did not know what he was talking about. wow. great stuff. i will doc it in another thread.

                  Wow - those mains are really awesome looking. The grill shape that you made for those really ties it together. Are those speakers your own design, or is that something published somewhere?

                    Nice work -- thanks for the tips. I'm thinking it might be a good idea to pick up an old iron somewhere to keep in the shop. Question: -- Any tips for keeping the magnet polarity correct, i.e., how you avoid ending up a pair that repulse each other, rather than attract? I first became aware of that issue when I was younger and trying to attract girls, and lately I've made the same mistakes with magnets.:o

                      grills are a life saver when your little one decides to start flinging peanut butter all over the room :eek:

                        I stack them and mark one side with a permanent marker (not permanent over the magments...), remove the top one and mark the next and the next. Then you have all the magnets with 1 side marked. Two marked will repel, two unmarked will repel, 1 and 1 will attract. If you want more permanent marks, try scratching 1 side or a dot of epoxy/gule.

                          I have some grills to make, thanks you! I have been wondering how I was going to hammer out these details
                          .

                            I let the magnets find each other. Take two, seperate them, find them a home right away. I have also put mags in the grill and stuck them to screws. Using two magnets, you can set them well below flush. The ones pe sells are strong.

                            Pictures of the mains are in my Photobucket below. '3-way'. They are my design.

                              Great info, amazing job on both speakers and grills. I usually go with a fabric steamer rather than an iron. So if you have access to one, try it out!
