Ugh, let's not go there. I made a lot of design and build mistakes but those are part of the hobby so no do-over there. And I made a lot of right choices like my table construction and Atlas on cork for the track. But in the absence of a good face-to-face resource like an easy to access LHS I bought A LOT of stuff that doesn't fit/match and/or work. In the end, joining the forum sooner would have saved me quite a bit.
