Does anyone have any good ideas on how to line up drill holes for magnets?

I'm using these magnets to hold a speaker grill in place. Magnets will be flush with wood/grill on either side. I just need to figure out the best way to get each pair as closely aligned as possible so the different magnet pairs are not pulling against one another as they would if they were slightly off.

Any thoughts or tips appreciated.

a square rule and a pencil should do the trick.

If you haven't covered the grill yet, just lay it on the baffle and drill all the way through the grill until the bit marks the baffle.

If you have covered the grill, you could drill four 1/16 holes and push a short finishing nail into each hole. Lay it where you want, then lightly tap the grill so the finishing nails mark the baffle.

Edit: notnyt's method would also work.

My first reply was kind of sarcastic. I'd just clamp it down to the enclosure and drill straight through probably. Then you can epoxy the magnets in place.

Dowel centers


Tap the dowel center into the hole, press the pieces together. The little tit on the dowel center will leave an impression.

Centers are overkill, just drill thru. That's the easiest and most effecient way to ensure that they line up.

My first DIY project. A dual, dual opposed setup

All great ideas. Thanks for the input.

I have not stretched the fabric yet so I could definitely drill through. Might look into the dowel centers also. I might be able to use those on other projects as well.

Also need to look into one of those square rules someday.

Mine not as clever...but worked.

I put the magnets in 4 years ago, and put formica over the IB baffle.


Got busy with life, but just 3 weeks ago decided to make the grille cover.

So, used a paper template, put the grille magnets where the baffle magnets were, traced the magnets outline and center line.


used that template to drill into the grille frame.


epoxy glue, done and lined up perfectly.
