Sorry for the lengthy first post. It's seems to be all the rage for guys, especially players starting their first build to purchase a Squire for anywhere from $79 to $299 with Affinity necks, Alder bodies, and some of the cheapest hardware and electronics you'll might ever see because some Squires are cheaper than a just a Warmoth neck. If they are lucky, they won't have to toss both The neck AND the body LOL!! But let's say you decide to convert to the string through body set-up. Is it absolute necessary to counter sink the holes? I've attempted to save one of these builds that had gone wrong, but didn't attempt the conversion, so Jnwould even know where to start. Also my body was ash. I swear Inuaed a trash cans of grain filler, a 55 gal drum of CA glue, and it seemed like a case of sand and sealer and still didn't get a flat surface l. At least it sure seemed that way. What typically is more of a challenge to prep a nice smooth, flat surface, Alder, or Ash? I know some guy swear by oil base filler. Can you get by with water based on one better than the other? Is there much of a sonic difference if you don't counter-sink the string through holes? Does anyone have an acceptable method of achieving the string through procedure WITHOUT a drill press? Are there any pitfalls that one should look out for attempting this mod? Thanks guys, I really appreciate the feedback gents.
