Backing plate threads stripped.

[Strs90]

On just my third use of my PC the backing plate shot off. My first thought was that this had happened. (http://autopia.org/forum/machine-polishing/74006-help-backing-plate-broke-scratched-car.html)



Luckily it hit the wiper cowl and didn`t do any damage. When I looked closer I found that the screw had stripped on the backing plate...



My question is.. only the first 3 threads are stripped because thats as far as it tightened down with the spacer... if i remove the washer I still have atleast 4 perfect threads below that.. does anyone know if there is someway I could make this one work or find an adapter to fix it? I`m sure I can rig an extension to it but do you think that to dangerous?



FYI.. I was extremely cautious about not overtightening it so please dont rub it in... and I`ve wasted too much money on this "hobby" than I should already have...

I would just buy a new backing plate. I`m also not sure of the spacer/washer you`re talking about, but if it is removable and only allows three threads to go into the spindle I wouldn`t use it. I have never used a spacer or washer with my PC.



The problem you`ll have if you continue to use it is the remaining four threads might give out and this time you might damage your paint. I`d also be concerned about the damaged threads messing up the threads in the spindle, along with metal shavings getting on your paint and buffed in :soscared:



For about $15 for a new BP I wouldn`t want to risk it.

yep, eliot ness cover that well



p.s. please tighten it down good this time!

Was I not suppose to have used this spacer? It was on the plate when it arrived and I could have sworn I read on something that it was so the wrench could fit between the plate and PC. I can`t test it without because the thread is too messed up and I need to find a die to fix it first.
