Quoted from eskedran:
I was wondering if I could sneak in and hijack your thread to ask a quick clarifying question...(I have enjoyed every moment of your restoration and appreciate all of your posts...I have learned so much!!!)
I just got a replacement BOP playfield...mmm...so pretty!!! I have been reading thread after thread to be prepared for swapping it in this winter, and have a question that was never directly answered.
I read somewhere that you need to predrill before screwing into the new playfield so that you don't risk damaging the playfield or cracking the clearcoat.
In determining the predrilling size for the bit, do I just go with one a bit under the shaft diameter of the screw, like I would with normal predrilling and go as deep as the screw is...or do I also need to come back and drill just barely through the clearcoat with a larger bit that will allow for the width of the shaft and threads? I don't know if the minor extra width of the screw threads is enough to crack the clear.
I'm just terrified to risk throwing away that much cash on a silly mistake.
Thanks in advance for any advice (and for letting me sneak in my question!!!)
Some good advise from lb1. Also I've heard it's a good thing to drill out the clear under the T nut fittings so they are flush with the playfield and the barbs bite into the wood not the clear, same for the pop bumper nails. Maybe someone who has done this can elaborate. kruzeman recommends this.
