Can someone make a video showing how to do that and make measurements and figure that out? Upload it on youtube!
I have worked doing re-keys, master keys, Grand Master keying, picking locks and a few other small things. Nothing really too difficult. Recently I found myself in need of a similar thing but one could not be found within my Lock parts and tools. I used a very thin brass tube from a wind chime in need of repair and got the job done. Look where there is an assortment of tubing. Check Fastener Suppliers like Hellman and VSI Fasteners, Crown Bolt.
I have propane heat, and it doesn't cause a problem with my plants. Perhaps your problem is humidity (or lack of it, actually). A cool air humidifier will add vapor to the air which most plants love. I boil water on the stove and the warm air vapor also helps. As the seasons change I also move my plants to different settings because of the sunlight changing. Most plants need a certain amount of light.
