Best way to arch the bottom of flat Pickup Rings

I ordered four sets of Dimarzio creme pickup rings for my projects, they all have flat bottoms. What is the way to arch the bottoms? How much of a curve do I want in them? sorry if this is a dumb question.

Re: Best way to arch the bottom of flat Pickup Rings

put the screws in and tighten each one a little at a time and it will bend, but it may distort a bit. Best thing to do is buy arched rings, but even the Gibson replacement parts are flat bottoms.

An idea I had once was to heat them in really warm water, and then put them on (never tried it but it seems plausible).

Just a thought - hot pup rings might damage the nitro? I don't know this - just something to consider...

Re: Best way to arch the bottom of flat Pickup Rings

what about sanding the arch in them, that way the top of the ring stays flat and they would fit the curve of the body?

Take a piece of 150 grit sandpaper and doublestick tape it to the guitar body over the pickup cavities.

Now take the mounting ring and rub it back and forth over the sandpaper. You will end up with a bottom that matches the curve of the top perfectly.

Any glue residue from the tape will come off with a bit of lighter fluid.

Re: Best way to arch the bottom of flat Pickup Rings

Sanding, as 69GTLP stated above, is the way to go in my opinion. If you simply bend them then they won't look right. A long time ago I tried bending rings using steam, then pressing them on a jar to arch them. I got the perfect arch but the top flat surface of the pickups made the rings look "funny". I used a drum sander on the bottom of another set of rings and it made quick work of it.

Buy the arched rings. They're inexpensive and only the bottom of each ring is arched as it should be.

Re: Best way to arch the bottom of flat Pickup Rings

I match sand them as Roman described. Cranking them down can end up with you stripping a screw hole or breaking a screw off in the hole. I see that a LOT.

Do it right and you win.

Yeah, the pickup rings will be playing a constant tug-of-war with their screws.

The correct ,and only way that Gibson have ever done it, is using a flat bottomed ring and flexing it over the arch.This is done either cold or by using hot water. Buy Gibson rings, not the cheaper aftermarket ones and you will
never have a problem.Look at any Gibson Guitar from the fifties to present day and you will see this is correct.Gibson have always used rings that are
moulded flat and then flexed to the guitars arch and are never sanded.Fact.

So are you saying that Dimarzio rings are not good quality? I was under the impression that they were spot on to Historic specs without the mold marks which I don't need. Plus they are only $4 each.

Re: Best way to arch the bottom of flat Pickup Rings

I use the DiMarzio rings. With respect to my colleague Singlecut, there is no correct way to do YOUR guitar. There is only the way that you choose to do it.

Forcing anything is a bad idea.

Re: Best way to arch the bottom of flat Pickup Rings

Well I'm not building a gibson and all of them except one will have my own headstock design. I'm definately going to follow Greg and Roman's advice and sand the arch into the rings. I can't believe the Markup on the Gibson name for parts, it's freakin nuts!!! It's like building a Mopar

69GTLP , You're free to build your guitars as you please and take advice from whom you wish. If you are repairing or restoring Gibson guitars then I think it best to adhere to Gibson parts and practices .As you say,your not building a
Gibson so it doesn't matter either way.If building to Gibson specs is not important then why not leave the area, where the p'up rings sit,flat or flatter than a Gibson. PRS and other top makers take this rout.

I'm not trying to get into a pissing match here, I love the top carve on a LP, Period. I just don't like the way the the rings look when they're bent it looks odd. I respect you knowledge of Vintage Gibsons, Wish I could afford one.

Re: Best way to arch the bottom of flat Pickup Rings

There's no pissing match, Singlecut is right. The PROPER Gibson way is the way he describes.

My point is that there is a better way than Gibson's.
