slngsht Posted October 12, 2009 Share Posted October 12, 2009 I'm looking for a new set of latches... tell me what you prefer. Link to comment Share on other sites More sharing options...
gjslutz Posted October 12, 2009 Share Posted October 12, 2009 Some EXP. aircraft have piano hinge style hinge latches. All you do is pull the hinge wire out each side of the hood and lift the hood off. This set up can follow a flat contour. On my RV-4 the hinge pin has a hand ground point to follow the radius.

JohnCh Posted October 12, 2009 Share Posted October 12, 2009 I have the Protex 27-1162/SC with the 613/7 SS locking pins. I like the fact that they have a locking latch and can take a pin as back up. Shipping a new bonnet from England is expensive! http://www.protex.com/images/product/large/27-1162%252FSC.gifhttp://www.protex.com/images/product/large/613%252F7+SS.gif -John Link to comment Share on other sites More sharing options...
MHKflyer52 Posted October 12, 2009 Share Posted October 12, 2009 Hi Mazda, Here is a photo of the setup I have which is an anchor nut with a knob with threaded shaft that gets screwed into and locks down tight in the anchor nut. http://picasaweb.google.com/MHKflyer52/ALotus7Replica#5391171812627928434 Lots of good ideas out there so I know you’re going to get the best information available…...have fun.

gjslutz Posted October 12, 2009 Share Posted October 12, 2009 Slingsht, here are some photos. More can be found if you google: vans rv hinge. http://www.vansaircraft.com/pdf/revisions/RV-12/29-02.pdf http://www.dualrudder.com/rv7/category/finishing-kit/cowl/ http://forums.matronics.com/viewtopic.php?t=63166&sid=bef7c9f8e58fbefd8adbe3762992418a You can find them for sale here: http://www.vansaircraft.com/cgi-bin/catalog.cgi?ident=1255367369-486-624&action=search http://www.aircraftspruce.com/catalog/appages/aileronhinge.php Another option http://www.aircraftspruce.com/catalog/hapages/camloc2700.php http://www.aircraftspruce.com/menus/ha/fasteners.html The cam locks should be installed every 3" if you go that way. The piano hinge is not visible to the outside seam. You need to just pull the hinge pin that is made of stainless steel wire. Mine has a eye bent on the end that I unscrew an anchor screw to keep it from moving FWD to the prop. I then just pull it FWD with pliers. As you can see from the photos most use counter sunk rivets to fasten the piano hinge to the cowl. Some people pull the wires to the rear from inside the cabin. enjoy Link to comment Share on other sites More sharing options...
andrew7 Posted October 12, 2009 Share Posted October 12, 2009 These guys have what you need, Mazda http://www.pegasusautoracing.com/group.asp?GroupID=LATCH I have toggle latches purchased from Ace and added safety clips to prevent accidental opening. My dad made his own Terry springs latches for his bi-fold hood, funny thing is, his name is Terry. Link to comment Share on other sites More sharing options...
solder_guy Posted October 12, 2009 Share Posted October 12, 2009 (edited) After LOG in Birmingham .. and seeing all the Cats with spring-loaded, stainless-steel, Terry Body latches in the front .. I bought a set off eBay for a reasonable price and installed in the front of the hood on my car. I still have the traditional tension latches in the back .. Of course I would have preferred the latches which can be secured with a cotter pin .. UPDATE: I see the same "Terry Body Latches" on that Pegasus page ..

powderbrake Posted October 13, 2009 Share Posted October 13, 2009 These guys have what you need, Mazda http://www.pegasusautoracing.com/group.asp?GroupID=LATCH These are the ones I use on my Ultralite ( 3045), I like the adjustable length feature Link to comment Share on other sites More sharing options...
eVox Posted October 20, 2009 Share Posted October 20, 2009 cheap. http://www.speedwaymotors.com/Trick-Styled-Latch,1582.html countersunk install on my hood: http://www.gatechlocost.com/wordpress/wp-content/gallery/1-9-09/IMAG0627.jpg The one JohnCH posted is a really nice design that I might get if I had the funds.

gjslutz Posted October 21, 2009 Share Posted October 21, 2009 The ones that came on my car are much like what Jerry has on his Ultralite (3045). On mine it has an adjustable screw head, not a latch; sticking up to fit into a slot mounted on the top half. The slot has a dimple for the latch screw head to fit down into. There is a small locking nut on the bottom of the screw; I think it is a 4MM nut. There is a little lock button that you need to raise prior to unlocking the latch. The latch is small and works very well. I have no idea where to get them as there is no marking on them. I didn’t build the car. Gary Link to comment Share on other sites More sharing options...

Mine is the same design as his, it works very well, and is the stock latch that came on my Birkin. Maybe they are available from Dick Brink.
