   Hi Paul, I didn't buy the motor mount with the motor, Milo still has it
   along with trailer, firewall, cowl and VDO test instruments for sale. I
   have the engine (with tech weddings oil pan mount), psru and wiring only

   Alex


   Paul, Jeff's plate and your design certainly looks strong enough judging
   from the BD4 and what you wrote. What do you think about attaching the
   nose
   gear to the oil pan mount plate I already have, and supporting the rear
 of
   the engine on it, having Jeff's plate on the front end? I have all the
   wiring you did for Milo on the top of the engine, was that wiring
 intended
   to be permanent? That might get in the way of any supporting strut
   supporting the engine from the top,

   Alex

   You might as well use the whole installation as is and plug up the holes
   on the firewall and beef up the firewall for the new hard points.
   The existing Tango hard points are in the right places for strength.
   It will be a bit of a kludge.

   It will need a new cross tube to stabilize the lower compression tubes.
   The upper tubes may be too high for the Tango so they will have to be
   replaced. The RV8 has a high firewall.

    Milo spent a lot of money on that and you probably bought it at a
   bargain price. The cast alloy oil pan is not deep enough but you could
  sell
   it on ebay for a couple of hundred. Some guy with an RX8 would love to
  have
   it. Then build a steel oil pan with enough strength for the front gear.
  The
   rad will have to come out from underneath if you
   use a nose gear.

   The wiring is intended to be for testing but it could be made permanent.
   May need a few tie wraps to stabilize it.

   The rubber motor mount heat problem can be worked around with custom
   rubber bushings made from sheet silicone rubber. Perry Mick made some.
   You will need to make a 2.5 " OD punch to cut it into doughnuts using a
   hyd press and a steel backing plate.

  The rad was just positioned under the motor temporarily while Milo did
  testing. Milo bought the oil pan mount from tech welding in KY, noted on
  the silicone mounts.

 I know its supposed to be quite light according to Milo's hangar
 partner, but more than 3 bucks per pound for sure. Don't know the weight
 yet, haven't got scales currently but there are new scales coming in a few
 weeks, the old ones were owned by an employee that left. You can see my
 current mount consists of 4*4 blocks :-)

 That oil pan is big bucks. It would sell fast on ebay.
 IMHO you need about 10 quarts so it is not ideal for AC. My 230 HP O-470
 is 12 quarts. Takes longer for 10 quarts to heat up on take off.

 If I were showing my RX8 at car shows I would like to have the oil pan.
 I don't go to car shows so nobody would ever see it :)

 That is a nice hangar. Is that in Williston?
 Did John Travolta used to live there with his 707?

That's the tango build centre in Williston, great people, I've hardly
opened my builders manual they've been great giving me direction the past
14 months (free) on how to do everything as I'm new to glasswork.

Ill put the oil pan on eBay when i get the new pan made up to support
oleo nose gear, (if thats the design we settle on. ill wait for a bit to
sell it to avoid any possible corrosion in the meanwhile

Alex

If you want the most durable and toughest nose gear I suggest a tapered round spring gear as found on some of Van's RV's. They absorb impact from any direction. Perhaps you can buy the parts from Van's.
I suggest not mentioning you plan on installing them on a non van's product :)
