PC backing plate bolt sheared off in 7424!?

clor0x · 04-29-07, 09:47

Has anyone had this happen before? I was detailing my father's car with my 7424, and PC backing plate, when all of a sudden, the backing plate flew off leaving the bolt inside the PC. This backing plate says it is rated to 10,000RPM and I was only working at speed 6! I bought mine from Coastal Tool (link here) less than a year ago, and it was supplied with a PC 6 inch backing plate.

Here are some pics. I'm not sure what to do from here...buy an extractor to get the bolt out? Try to get Porter Cable to replace it? Thoughts?

Here are the pics:

Contact Porter Cable and explain exactly what happened (it's a defect in the bolt), don't start cussing or anything, just say you are really displeased! Shouldn't have a problem though.

You might want to contact Mike at Coastal Tool first and do as above, he might have a better/faster solution, he's a real nice guy so please treat him like you would want to be treated .

Yikes, good thing I threw that BP/PAd in the trash. Luckily the paint wasn't damaged.

Yea, the white pad will explode on you...guess how I know

The backing plate has been working fine...did 3 cars with it...who knows?

Coastal Tool said they will replace it free of charge

Have not heard back from Porter Cable yet, though. Gotta get a flexible backing plate for this thing that doesn't fly off! Any suggestions?

The plates sold by Sonus, Excel, Danase etc are about as solid as you can get.. and much better than those PC plates overall.

Once they fix it, buy a Mcguire's 5 inch backing plate part number #W64. Check the local auto paint stores locally where you live. It has a centering button for aligning pads. It's better than the LC backing plates.

PS. Told you so

FWIW, I've never liked the Megs' backing plates for PC use. Not nearly as flexible as the LC plates - doesn't matter much on a rotary, but having a plate that flexes well is a big benefit IMO with the PC.
