The face of the cowl that aligns to the rear of the spinner is not square with the plane.  It is designed to align properly when the engine is properly offset.  That should give you a clue that you have the offset correct.  If you use rubber motor mounts that are too soft, they will allow the engine to sag and screw up your alignment as well. Be sure your mounts are ok before you align and fit your cowl. (Guess how I know this.)

 

I am really blown away by that prop!  :>)  I can hardly wait till you crank it up.   My plane causes the front strut to bottom out when I firewall it, but if you saw the video of Tracy’s plane and think what yours will do with the turbo….It causes some scary thoughts!

Be sure you tie it down and don’t just chock the wheels….It may retract them…to the rear!

I was wondering if anyone would notice that Bill.  Lancair called for 1.5 degrees to the right, and down, for their stock Continental/Lycoming layouts, and with much discussion, we decided that it would work for us.  We have 4" clearance with the tire flat and the strut compressed, that should be enough I hope.  That fan is nasty looking isn't it.....(:-)

Looks really good, Greg.  What thrust line offsets did you use when you built your engine mount?  How much ground clearance do you have with that monster prop?

 

By the way, everybody.  I have a set of prop bolts that came from Saber Mfg. that I didn’t use.  They are 7/16 X 6”.  If anyone could use them, I can make you a good price.  I screwed them in one time, but realized that I needed to add an extension, so couldn’t use them.

A couple of you wanted to see what's going on, so here we are.  Manifolds are out getting flow tested and final welded.  Next week is plumbing and wiring time.  Gotta' take a couple of days off, and do Hunney-do stuff.  God, I love this stuff......(:-)
