I have never had to re-drill... again only due to being blessed with serious step by step help from a fast pro, cough cough, Reecedad, cough. Including bodies he drilled for me. (I got a drill jig finally to do my own)
But a common trick I have heard from folks who know is real simple... wood glue like Titebond II and toothpicks. Once hardened it’s like the hole was never there and re-drill as necessary. Shoving a simple toothpick in there instead of making paste sounds a bit more simple.
Get a drill jig if you think you’ll keep at this hobby/addiction. Worth the money. Next thing you know you’ll want to send one in to one of the leagues and you will start racing EVERY MONTH!!!
The addiction is real. You’ve been warned.
