I almost didn't play my TWD since I got it, because it was basically unplayable due to the outlanes without the usual mini-post above the plastic inlanes top. Some have drilled a hole to install a regular post, but... I couldn't decide to drill a brand new playfield.
So I had another idea this morning, with a piece of very thick/robust copper wire I had left.
A little bending and a washer later, here it is. Works perfectly, maybe I'll revert to the original post above to get a good balance.
