why not just laminate it after filling in the holes with bondo?
Well it's in pretty rough shape. Especially near the bottom towards the back, there is a chunk of wood missing. I know normally people would flip this machine on its side, completely cut out a foot or so of wood, and replace it, but I think that is a bit overkill because it's the back of the machine, not the front. So using my father's idea, you would not even see the missing wood unless you were looking at the back of the machine. We also do not have the bit needed to carve the t-molding in.
Off the top of my head, you will have an issue with the t-molding matching up. Depending on how he attaches the wood, you will have to fill screw or brad nail holes anyway. Unless he plans on gluing the panels together. You are going to have to paint the wood to give the vinyl graphics a good surface to stick to.
I brought up the T-Molding immediately! He said you would barely see the part peeking out, though I don't know how true that is. Though I suppose if we painted it black and use black t-molding, perhaps it would in fact be almost impossible to notice?
I also figured it would be a bit easier to put on the new artwork onto the thin piece of wood instead of directly on the machine. Especially when it comes to cutting it with an X-Acto knife.
And yeah his plan was to glue it on.
