[FONT="]This is not your normal HVAC question, but I figured youd be most qualified to help me design what I need.[/FONT]

[FONT="]I have a FABCO Signi-Fire wood burning stove (the company no longer exists). I find the fans to be too noisy, so I want to replace them with blowers. There are 7 holes with 3 ¾ space below and 5 ¾ space above. The motor needs to be installed below, or it will get too hot, and I was thinking of extending the shaft of the motor and attaching a metal squirrel cage with the open end facing downward. Im not sure if this needs to be surrounded by a case or if it will pull air without being enclosed. This is the opposite of most squirrel cage assemblies, as they would have the motor in the heated area. Im not sure if the squirrel cage should be slightly under the diameter of the 7 hole, fitting slightly below the opening or if it should be larger and fitting above it. Im thinking a bearing supporting the motor shaft above the squirrel cage would be helpful. Im attaching photos, diagrams and information from FABCO and would appreciate any suggestions you may have. Due to the fact I need 4 of these fans, suggestions for locating used/surplus parts would be appreciated, also.[/FONT]
