I started making a wooden tank lid for my Corn snake tank - and after just reading Ryan's tutorial: Custom Glass Tank Lid, it gave me a few additional questions and answers )). 1. I have a concern about placing the heat emitter directly on the hardware cloth that covers the hole cut for that purpose. Athena regularly stretches up toward the top of the tank - is there any concern about her getting burned coming in contact with the hardware cloth directly under the heat emitter dome? Technically it shouldn't be any different from her current set-up as the heat emitter is sitting directly on the screen lid -- but maybe that's a problem as well. 2. I purchased 2-part epoxy as it was recommended as a stronger hold than just silicone (I have aquarium silicone already from other projects, but maybe that is different). I am planning on hinging the lid to the back, so I don't have to take the entire lid off everytime I want to get into the tank (it's heavy). And I'm using 2 locks just like Ryanbp used --- what do you recommend for securing the hinge to the plastic frame on the top of the tank and the locks to the glass? Thanks to Ryanbp, I'm not going back to the store to buy vent covers (registers) for ventilation -- just cutting two more holes and covering them with the hardware cloth. It will be easier to make and easier to adjust the amount of ventilation needed. (Cover one up if it is too much and uncovering when needed ) I think I am using the same material as Ryanbp - it's 3/4" thick and covering a 75 gal tank. It was cheaper than plywood and it looked nicer. It was also more dense then the plywood - thus adding to the weight. Thanks!
