: I may be interested in the single version. Do you have a website etc for
: technical details and/or how willing might you be to help out?

Doug,

The website has yet to be updated with detailed info on the Combi Double/Single.
I will make the offsets available when testing is completed. Several other
folders are presented in some detail on the site listed as a LINK below.

Once there, Click on "Here is a Site Index to All Pages"

Take a look at FAP-16, followed by TDY-16 and FAP-15. The building process
displayed is similar to the Combi Double/Single designs.

Click on "Update page with links to the latest information" for general
info on the Combi Double/Single designs.

In addition I have numerous additional pics and building info available for
the Combi as well as the other designs. Contact me directly for additional info.

Hope this helps,

Tom
