Give the glass a try if you want to, you can always take it out later...I have removed the wooden pieces that held the glass shelves and measured and marked where I plan to cut. I haven’t cut into the main cabinet yet, but as far as I can tell, it is mostly solid wood except the back panel behind the bottom cabinet and possibly the doors. Fingers crossed. I still plan to waterproof the entire inside and bottom after I cut the top, sides, and drainage hole. I am going to put aluminum screen on the top and both sides. I really like the glass in the front, but I’m wondering if it would be best to screen it as well. I’m toying with the idea of leaving it and seeing how it works for a couple of days before putting the Cham in, and then screening if necessary. I am only getting a little bit of work done each day after work, but I will post pics when I get a little further along.
