Subject: Tango Cirrus type nose gear.

   This uses a 1.5 inch OD .125 wall 4130 tube for the nose gear
   strut. It is bent at a 45 degree angle with a 10 inch radius.

   You need to search Google for a short 2 inch air cylinder
   for the damper. The latest trick in shocks is to use a separate reservoir
   and the ID of the small tube connecting the two controls the damping.

   BTW Zero manufacturing makes some great oil pans.

   ------------------------------____---------------------------

   These cylinders might work. Connect the upper port to
   a pressure can with small tubing. Fill the can about half way with
   hydraulic fluid. The remaining air in the can will serve as the spring.

   A two inch stroke might be about right.

   BTW I just discovered Linux and my display will do this.
   Very useful when it comes to screen captures of web pages.

   This is a more compact version.

   Hi Paul, that's absolutely spectacular!

   Will it still be possible to fabricate this at do-rite in CA? And for all
   your effort and the design changes I will be happy to package up and send
   you the Greddy oil pan on my engine as a
   token of thanks.

   Order the motor plate from Jeff first. Have Jeff drop ship it to me.
   Jeff call me when you are ready to ship for a shipping address.
     Do rite will need that to weld the MM.
   Alex, I will give you a list of materials to order from AC Spruce
   or any other 4130 tubing supplier.

   Alex, Do Rite can also weld the oil pan. Zero does not stock a suitable
   deep drawn pan so Do Rite will have to weld it from sheet.

   Here are the dims on the four 4130 .049 wall tubing sizes.
   1/2 inch round for the lower diagonal bracing.
   1 inch round for the lower compression struts.
   3/4 inch round for everything else.
   3/4 by 1 and a 1/2 .049 rect. for the rear beam.

   Add it all up and order
   it and have it dropped shipped to me.
   I'll send you a shipping address when you are ready.

   I have an RX8 steel  oil pan we can get the hole
   pattern from.

All copied Paul, I have a renewal and company courses mon/tue + flying on
wed back to base, I will get on to it on Thursday.

I contacted Jeff twice
about 3 months ago on his gmail address supplied on the rotary
engine.net <http://engine.net> website, but couldn't make
contact, do you have another contact email for him,

Alex

I am working on it.
