Hi all
Managed to get hold of some Interlok busbars which I have been after for a while since they ceased trading. Not exactly what I wanted as they were goalpost ones, but hey ho, beggars can't be choosers. Anyway, the rear rests of these are made of a clear plastic, perhaps an acrylic material. First outing with them, both of the acrylic threads snapped off the rear rests, so I not only have a knackered and useless rear Interlok busbar, I also have 2 blocked Summit Tackle banksticks.
Any recommendations on how I can get these out of the backsticks without damaging the threads on the banksticks. They have snapped off below the top face of the bankstick so there is nothing protruding that I can get any purchase on with a pair of pliers.

Either drill a row of small holes in as straight a line as possible, then gently tap a slotted screwdriver into the slot and unscrew (only drill a few mm in, not right through), or maybe try a left handed drill bit (in reverse obviously) of about 5 or 6mm. Failing that, just keep increasing the drill size in 0.5mm increments up to about 8mm (3/8” is almost 10mm and the drilling size for tapping M10 is 8.2mm), but only go as big as this if your pilot hole is bang central. At some point the acrylic thread will just collapse and you can pick it out and break it up with a small screwdriver or o-ring picker.

Get a small flat head screwdriver, gently apply some heat and then push it into the plastic, when it cools just unscrew the snapped off bit.

Could use a screw extractor
They work on the reverse principle
Worth having a set for just in case problems

Thanks all, the heated screwdriver did the trick!!

Dunno why I didn’t think of an easier fix Chris! Probably because I’m forever trying to extract sheared metal bolts/threads, not plastic lol 🤦🏼♂️

The hot screwdriver trick is the recommended way to remove broken stems from dart barrels, could see no reason why it wouldn't work on this.
