Step 5: Installation: Step #3

Picture of Installation: Step #3
Next we must drill the hole. This is the most difficult part of the installation process. It is in your best interest to take the tension off of the strings to get rid of forces that may be pulling on the wood. You may want to practice drilling holes on a scrap piece of wood if available to get a feel for the drill. Using a good sharp 3/8" spade bit, as seen in Figure 2, very slowly (fast drill speed, very little pressure) and carefully drill the hole in the body. Be steady and smooth or you may cause the body of the guitar to splinter around the hole.

I just read what the guy said before me about the forstner bit. That is also a very good bit to use. Either one of those bits would be great to use. Alot better than a paddle bit.

I have been a carpenter for about 4 years now. I have built guitars and cabinets alike. When I have an important hole to cut that I want to be very clean I ALWAYS use a BRAD POINT BIT. They are designed for clean cuts. Paddle bits or (Spade Bits) as you called it are more for rough work. Its also important to go slow when drilling dont get in a hurry, you will regret it. Great guide though. Just thought I might extend some of my experience.

If you drill the hole with a Forstner bit you will have no splintering at all.

I dont think that i could due this to my acoustic...i wouldnt live with myself if i knew i drilled a hole in the bottom of my lovely guitar. even if it was for the greater good.

A little masking tape at the location of the hole inside and out will help prevent splintering.
