Hi! My name is Tim. I am a journeyman sheetmetal worker. At present I am working full time in the office doing autocad HVAC. If you have any sheetmetal, autocad questions or comments about my web page you can e-mail me at support at tinner.com ( I didn't use the @ symbol because I don't want the web crawlers to get me e-mail and send me a bunch of junk.
