Full credit on the polish job goes to my father in-law, he's very meticulous and kept requesting finer compounds and a better polisher until it got to its end result.

I also did a front axle fairing, just a bit better construction than the foam board, based on an NACA profile.  I rebuilt the entire front axle and suspension to get to a straight round tube axle to make it easier to streamline. Looks like an aero improvement but not enough results to determine how much of a difference it made.

Yes that would be illegal but if you do a stationary moon disc on the back side of the wheel & run the fairing into that you would be legal because everything would be inboard of the wheel.

Sid, doesn't the rulebook say no fairing can go beyond the narrowest inner vertical plane of the ties? If the end of this fairing does not penetrate the inner vertical plane of the tire (not wheel), it is legal. If it does, the fairing needs to be trimmed back.

Remember also: Just because it's not a legal Lakester doesn't automatically make it a legal Streamliner. Wayno

Yes I am. I brought the Tank back down last weekend. Finishing re-assembly for the May El Mirage meet. Made some changes to the motor which should prove interesting. Bigger cam, better (not bigger) valves and I removed a pound and a half of reciprocating mass from the valve train. Stay tooned.  :cheers:

Yep, we're all reading the same rule John. Use the convex shape of a Moon disc to transition the wheel/tire to the wing. If the disc is mounted to the wheel, mount the center of it to the end of the wing then it's clear of the inner plane.

Yep, we were all thinking of a flat disc that sat inside the line of the wheel

In other news, after a disagreement with photobucket over the value of my 86 photos, it would seem that I no longer have a phptobucket account
so if you are reading back thru the blog and find all my photo's are  missing, you now know why

G, I sent Mike a message, told him you wanted the tires and I would pick them at SpeedWeek if they were still available.  Anybody from the BIG island shipping a container back and forth this year?

I can't find a one in the pre-enters.  That other smaller island has lots -- would that help?
