Erection and Maintenance Instructions

Please find below a series of PDF files to help with the erection, servicing and maintenance of some of the main Comet windmills.



  1. Hi,

    We have 12 ft C pattern comet windmill, serial number is 670.
    The head wheel has come loose and rotated on the shaft, I have tightened it up but I was told it would be out of balance, the mill is working again but it’s slow to start . I just tried to download the balancing comet windmills PDF but it won’t let me. Just wondering if I could get a copy of the maintenance and balancing instructions.

  2. Hi Jason, we have fixed that problem so please try to download these documents again.

  3. Hello,
    My name is Eddie Sosa and I work for the American Windmill Museum in Lubbock, TX. We purchased a 20 foot Comet as well as an 8 footer through Al Thomerson with Topper Windmill in San Angelo, TX. What I would like to know is if you can email me instructions on assembly of the windmill wheels and also the towers. I’ve separated all the main components and have a real good idea which parts go with the different size mills, but some sort of diagrams would be helpful. Any thing you could email me would greatly be appreciated. I can be reached at

    Thank you,
    Eddie Sosa
