Plenum fabricating in SE Michigan?

Hello, I am in Farmington Hills, MI, and need to put together a plenum(2) that will connect my newwoodfurnace to my main furnace plenum and return. If anyone here is good at cobbling such things together, please let me know, thx! Most HVAC contractors don't want to do it w/o also providing me a new furnace. Guess the economy in Michigan is not bad enough

Just want to say thanks Capt for the Ryan suggestion. He appeared to understand exactly what I was looking for and was able to suggest a reasonable price for the work involved. I would have tackled this myself, but the intricacies of my metal requirements and plenum needs drove me to try and get someone who knew what he was doing. So, looks like the heat output hookup of my caddy should wrap-up this Friday. I already did all the chimney connections, so I look to be burning w/ wood by early next week. I will post pics.

Good idea. Think I will try that tonight. Bout time she got fired up anyway
