Anybody out there convinced that they know the PERFECT way to fasten the cowling to the firewall? I plan to use piano hinge to join top and bottom halves, as well as connect the sides to the firewall, but the top and bottom connections to the firewall will be little aluminum angles and Southco Camloc imitations unless somebody convinces me there's a better way. Any suggestions? The engine is on the final mount, and looking good! See http://home.hiwaay.net/~langford/corvair/01061003.jpg . After seeing that, you VW guys must be feeling a little insecure, eh? If it makes you feel any better, I AM using 94mm Volkswagen pistons and cylinders, but I've got SIX of 'em! A slight miscalculation at the Corvair College resulted in missing the bottom of the firewall by an inch (the exact width of WW's capenter's square), but the little "perches" in the picture solved that, and resulted in improved mount geometry, at a 1 pound weight penalty. Otherwise, the engine is exactly where I wanted it, with an eighth inch clearance above the fuel pump, and a half inch from starter to firewall. The extra steel sticking out of the front will be to support the cowling, making lower cowling installation a snap. I laid up the top half of the carbon fiber cowling tonight. The bottom comes tomorrow night, and then a little surgery...

He has pins (they look like 1/4 inch dowels about 3/8 to 1/2 inch long) that stick out of the firewall side of the cowling between the fasteners. He has about three or four, but even two would work. These line up with holes in the firewall and make lining up the cowl a snap. Very easy to do and could be retro-fitted to an existing set-up. ===== Frank Ross, San Antonio, TX, __________________________________________________ Do You Yahoo!?

William has an extraordinary talent we can all learn from and he has certainly taught me. Then there is another gentleman, Mark Langford, who has also gone beyond the call of duty to support my trials and errors in the construction of my plane. To both of these gentlemen, I am indebted and only hope to some day return what they have extended to me. William has asked that I post the photos of the mount he fabricated for me. In these photos you can see where I have temporarily placed the mount on my KR-2S firewall. Here is the link: http://sites.netscape.net/n886mj/mount I am also sending this to the KR net as I want to promote the Corvair engine and mount as much as possible.
