Methyl alcohol will turn that Locktite into - well
- "Like Butt-ahh"!
Soak the bolts overnight, then use a Nylox (abrasive nylon) or fine brass
wire rotary wheel in a high speed drill with your bolt clamped in a vise. Depending on the thread size you may want to use a Dremel instead since the wire wheel attachment is very thin. Don't use steel
since you can easily damage the threads. Run them through a die by hand to get off any remnants. Rinse with methyl alcohol.
Don't forget to wear your polycarbonate
) safety shield since nothing ruins a good laugh like a piece of wire embedded in your aqueous humor.
For the holes, fill them with methyl alcohol, tape some metal foil over the top to keep it from evaporating, let soak overnight. Use an abrasive nylon flute brush chucked in a drill - picture below - and gently "plunge" the hole,
Chase the hole with a tap to get out any remnants, blow them out with compressed air then rinse with methyl alcohol.
Have a couple of shots of the methyl for yourself (not) and pat yourself on the back - you've got whistle clean threads!
