<DIV><FONT face=Arial size=2>I should have known. Karl you are the
aluminum man. BTW the header you made for my ST2330 has survived a
major crash. It got bent a little, just put it in the vise and
straightened it out to live in another airplane.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Where can one purchase this fine aluminum and how
much should it cost?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Sounds like you could come close to the
weight of c.f. Although I like the swept back gear design for some
airplane designs.</FONT></DIV>

<DIV><FONT size=2>Wayne,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>7075T6 should never be used as landing gear. It will
fracture</FONT></DIV>
<DIV><FONT size=2>when trying to bend it. A better choice would be 2024T3.
This is the</FONT></DIV>
<DIV><FONT size=2>springiest type of aluminum available. Since a lot of
suppliers do not</FONT></DIV>
<DIV><FONT size=2>have it as a stock item, 6061T6 is the next best type to use
and is readily </FONT></DIV>
<DIV><FONT size=2>available at most metal suppliers. I have been using legs
made out of</FONT></DIV>
<DIV><FONT size=2>1/8" - 6061T6 and had very good results with it. Total
weight of the 2 legs</FONT></DIV>
<DIV><FONT size=2>without wheels and pants is 6oz. The gear legs are of the
plug-in type and</FONT></DIV>
<DIV><FONT size=2>overlap </FONT><FONT size=2>inside the Fuse. I have one set
that has outlived 3 </FONT><FONT size=2>planes and is </FONT></DIV>
<DIV><FONT size=2>still in use. </FONT></DIV>
<DIV><FONT size=2>I seen too many carbon gears break on heavy landings (read
semi crashes)</FONT></DIV>
<DIV><FONT size=2>and to replace these is not cheap. I buy a sheet of 24"x 48
" and cut the legs</FONT></DIV>
<DIV><FONT size=2>from this. You have to remember to cut the legs with the
grain running along the</FONT></DIV>
<DIV><FONT size=2>legs and not across (yes, metal also has a grain to it !).
The bend at the</FONT></DIV>
<DIV><FONT size=2>upper part of the leg should be done over a large radius (1
1/4" to 1 1/2" Dia.)</FONT></DIV>
<DIV><FONT size=2>Do not make any sharp bends and the alum. will not
fracture.</FONT></DIV>
<DIV><FONT size=2>This works for me.</FONT></DIV>
