    The beginning of a cowl.
    How did get the base of the cowl curved to match curve of tub?

    Template made for mounting hardware

    This how to get sponson tubes glued and true with each other and the water

    Once everything is trued up and clamp weight the sponsons down

    After glue is dried I will cut the tubes in half

    With metal or CF tubes slide a piece of boom tube over the sponson tubes and do the same clamping and weight the sponsons down

    Mark Bullard and I have doing sponsons like this for years and it works

    Is this a Zipp Kits kit? I'm currently building the twin 45 and looks similar.

    No it is not a ZIP KIT

    It is an SST MARK BULLARD TUB DESIGN with flat plane front sponsons

    It is a F twin. It will have 101’s for power

    Thanks for the information. Can't wait to see finished project. Have been out of the racing scene since mid 2000's and looking to get back. Looking for .45's for my twin. It seems MAC and CMB are the main choices. Looking for any information to help with decision. Thanks.

    MAC,s are not available now except as used

    CMB VAC 45 is a good motor. I run one (older blue head)

    NOVA add 45 is a good motor as well. It is a little less expensive

    You can get the CMB from Stu Barr
    Also you can get a good deal on the Nova dd 45 from Mark Bullard 256 303 6423
