I just finished this today, totally all cut on 20" scroll saw, I thought I would do a quick tutorial of how I did it, I took a few pictures along the way, first I used 3/4" 1x6 pine for project, this was made in 3 layers to give it a 3D look, it measures 24" for the red circle, 20" for the white circle, cut 5 boards 25" long for the 24" red circle. cut 4 boards 21" long for the 20" circle, now edge glue boards together( I used my Kreg jig with pocket holes too), once that is done, find center on each set of boards, draw a 24" circle on the larger boards, then draw a 20" circle on the shorter boards, I made a 20 template from 1/4" under layment for tracing baseball threads & repeatable tracing, once that was cut, I used it to trace threads on the the smaller circle so I could cut them out, now before you can cut this on the scroll saw, you will need to cut the corners off your boards to allow for it to turn in your 20" scroll saw, drill entry holes for your cuts, then cut both circles and threads, now do some general sanding and paint separately, you will need good quality paint & put 2 coats on, once paint has dried, center & glue/nail together, you can cut a number or logo to finish like I did. Hope you have good luck.
