I cut the mortises, but ran into a problem. The mortises for the rails and rebates for the glass channel are really close together. On several of the stiles they broke right there. Dang.
The dry fit is OK, and the rails are all in good shape. I could probably make this work with some epoxy and filler pieces, but I’m going to re-make the stiles a little more carefully — leaving more clearance between the rebate and mortise.
