I found this concept on a scroll saw site by Steve Good. I didn’t use his .pdf pattern as it was easier to simply draw this in VCP, but the idea was all Steve’s.
This is just painted 1/4" MDF, cut with 1/8" mills. I cut the top 1/16" with a downcut and the bottom 1/16" with an upcut as I hate sanding.
Nothing special. Not a keeper, but a fun, fast project nonetheless.
