I've heated up the heads of carrage bolts with a torch and then quickly/carefully pulled it from underneath with a pair of vice grips untill the square shank is fully sunken into the melted lexan, wait for the bolt and lexan to cool and harden and then put your nut on and carefully snug it up. Don't pull the hot carrage bolt too much or you'll end up with a melted ring of lexan oozing out around the sides of the bolt head. You may want to use a regular nut with a lock washer instead of a nylon lock nut. Lock nuts exert pressure on the bolt when screwing them on and you might crack the area where the square bolt shank grips into the lexan before you even get the nut fully tightened. |

Simplest option is to drill your wood at 5/16" and drill the Lexan at a 1/32" or 1/16" (11/32 or 3/8) larger so the square part of the carriage bolt drops down. The bolt will spin then, but that shouldn't matter and you won't crack your Lexan. |

I thought standard carriage bolts used on arcade panels were smaller than 1/4 (not 5/16)? 7/32's or something like that? Wade |

Wade --- End quote --- Now that you mention it, standards are 3/16th's. OSCAR is using 1/4-inch for his restrictor plates to eliminate play. 5/16 is probably too big. |
