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.

Alex Molteno

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

Jeff was behind on his email. Try again.
