Geez, I thought that was Mrs. Doubtfire!   I need frames that have a taller viewing area without looking like I'm lost in the 70's (again  )

What you look like is irrelevant    How fast you go is.

Thanks for the encouragement. Now I won't feel so bad if I show up with my glasses pulled up and taped to my forehead!

If you should run a record and your crew looks at you and says you look goofy we're not going to impound with you.  Find a new crew.

[sofadriver]

If I do make it to impound, will I have keep the tape on for final tech? ............................... 

[Nortonist 592]

Yes!!  If it makes the inspector giggle then certification will go much smoother.

Use duct tape ... it is an official AMA motorcycle racing component ...

I'm finally starting to be able to get some things accomplished.

Got my rear axle shortened and finished the axle adjusters. My buddy Glen cut off the new forks by 4" and made new end caps. I rebuilt them and got them mounted. I still have to drill and tap one of the sliders to accept the larger RS125 front axle.

Today I scored 4 3"x4'x8' sheets of nice, carvable foam off Craigslist for $50. A good deal and they will work great for the body buck.

At long last I was able to get the upper body shape plotted and cut out.  My buddy Dave sent me the measurements to mark it onto one inch grids (while vacationing in Malta, no less!). I used a naca-021 shape but narrowed it about 2 1/2". I'll use the same shape for the lower body but it will end with a naca 66-021 type tail because I can't get my knees and feet into the 021 shape. Such is life.
Hopefully, I can get the buck done in about 2 weeks.

There's a faint light at the end of this tunnel.

Mike ...  the light at the end of the tunnel sometimes is a train coming at you.   You are doing well, don't rush it.

That is typical.  There is one shape for the body and front fender in top view in the plane of the axles.  There is another shape in top view for the body alone above the front fender.  The third shape is the body and front fender in side view.

making progress...........

playing with the nose shape........

Started to get the body ribs installed.

Note spray paint dusted on the back edges of the cockpit form. I was able to get that perfect shape by draping some small ball chain over two nails set at the proper distance apart and then letting it sag down to the desired depth (height). I very lightly dusted it with spray paint to get the outline and cut it out. Kinda' nifty I thought. (I should have been a rocket scientist  )

(I should have been a rocket scientist  )

Wernher von Braun would approve.

"Out of the box" thinking to solve problems is more important than being able to repeat formulas from memory.

Mike, I like that ball chain idea! that way you get a perfectly symmetrical shape. Good job.

If you use it,  make sure the nails are level.
