    Hello, I added 2 Reverse taper pots to my 5220 for the bridge and neck volume but they are 3/8" shafts so now I have to ream those 2 holes. Is it better to ream from the inside or the top? Any suggestions welcome

    Thanks!!

    From the finished side. If you push from the non finished side, (I'm not sure you can even do that with those cavities?), it can cause large shards of finish to flake off. By pushing on the finish itself, you're holding the finish down as it were. And I would suggest a hand reamer as you will get better control and can be more gentle.

    Had to ream the hole on my 5220 switch to put in a Gibson style. I wrapped a fine grit sandpaper around a pencil and used that....actually came out really clean.

    Cover the hole with masking tape first, just in case.

    Absolutely from the finish side. A trick I used was to tape a washer over the hole. It protects the finish and keeps you from reaming to large of a hole if you find the proper size washer. It worked on my Epi. Just tape will work well, just go slow and check the hole size often

    But you HAVE to peal the tape back at a 180 degree angle or it can pull finish off! (Ask my Strat how I know that...)

    I will say, low tack painters tape is a better option on guitar finishes than standard masking tape

    Thanks for all of your replies! I reamed from the top as suggested and used a hair dryer on low to help avoid chipping. All went well thankfully.
