Quoted from vid1900:Glue the insert from the back of the playfield so it stops moving around.
Yes, drill some holes into the old wood to give extra tooth to the wood repair epoxy.
The stuff that comes in a "log" and that you kneed together works great. Sand before it is 100% cured, or it is really tough to sand.It's a lot harder to spot clear, but if it's just a saucer hole, you might do it with a small brush.
What is the brand of the wood repair epoxy you are using, where is it found? I went to Home Depot in the aisle where the wood putty, stains, etc is and couldn't find any sort of log stuff, just putty, plastic wood filler etc. I asked the paint dept. employee right in the area and he sucked and didnt know squat about something that would be strong enough.
Here's a photo of what I'm trying to fix, as well as the mini playfield side also before installing a cliffy.

and here is what I bought (my guess is it won't work and isnt strong enough to take a beating)

Thanks for the help.
