Not wanting to re-invent the wheel ... ?has anyone come up with a template for drilling holes in an enclosure for a 2 to 3 inch speaker ?
I was hoping to find something that I could print out and tape to the outside of the enclosure to use as a guide for drilling sound holes in a regular pattern for a 3 inch speaker.? If not, I will see what I can come up with and I will post to the group.? Cheers Michael VE3WMB? |

That looks good. Or the following works for me. Take a piece of veroboard, draw a circle slightly smaller than the speaker on it with a drawing compass, the sharp leg should be located in a middle hole. Firmly tape board to the case where you want the grill. Then drill thru all the veroboard holes inside the circle with a small drill. The board keeps the holes aligned even if you wobble a bit. ? A drill press makes it much easier (and cheaper on drill bits). ?

I painted mine with layout dye (Dykem) and scratched a grid into it. At the intersections I hit it with a punch then used a hand hole punch to poke the holes. Alcohol removes the layout dye. That's just a temporary front panel as I decide what it's going to have and look like as a final product. The end result panel will be too thick to hand punch (0.100") so I'll have to drill it. I had to mill the slot for the display, even in the thin 0.035" aluminum I'm using as a temp panel.

A friend used a piece of steel mesh with round holes punched in it. He then clamped the mesh to his front panel and used a drill press to drill every hole he wanted (the drill bit passes through the holes easily and the mesh centers the drill bit). The result is very professional looking. The rim of the speaker is glued inside the case.

开云体育Brian VK7KBW might respond, if he sees your request, to say that he used a stainless steel drainer, designed to go over the drain hole of a kitchen sink or basin, as his drilling guide for the speaker holes. Worked out very well. Bill, VK7MX On 15/06/2017 10:37 PM, Michael

Drilling all those holes is a lot of work. Get one just a little out of place and it will stand out like a sore thumb. I've always found it easier to simply make a big round hole of the appropriate size using a punch or metal nibbler and putting a grill over it. Lets more sound out of the box that way also.

The one's I've seen use 4 bolts at the corners of a square-cut grill placed on the underside of the cabinet.

The grill over a big hole has been my approach as well.? I use a hole saw to cut the round hole, file any metal ridges down, and then sandwich a piece of mesh between the speaker and the chassis.? I have scavenged the mesh from AV equipment going in to the junk pile at work.? Mostly old subwoofers from PC speaker sets.
