I burnt the nylon cootie fibers off my Cuc windshield mask, scraped off the old white glue residue, and it's ready again. Body is cleaned and dry, ready for the mask

Matt Bishop gifted me this cool vintage driver :)  The paint isn't lazer perfect but what it lacks in perfection, it more than makes up for it with patina and klass. So I left it "as-is", cleaned it with a soft toothbrush, and drilled a .035" hole into his neck to accept a CA coated piece of .032 wire. He will be secured via a punched hole in the cockpit deck and a small earring clutch

I aint NO ONE to suggest anything Mr. Pablo,but maybe just repainting his goggle lense silver again would make that driver look pretty damned good to me.(Just sayin.)

Mike, the owner agrees with you so I did it. For some reason, I do better with a toothpick than a brush  :)

Another nice creation! And I didn't just say that because it's blue.

16D size new vintage brushes custom fit to the holders by gently facing all 4 sides on 2,000 grit sandpaper by hand.

Then I used my standard brush pre-radius setup with the actual Cox EB to, uh, pre-radius them  :)

Springs are new Pro Slot 2013 double overheads. Now all I have to do is set the magnets.

The arm OD is .540 and the target goal for the hole is .580

Using the air hole tab gizmos at the rear as test spacing devices by opening or closing them, it allows me to push the mags in to the hilt as a means of adjustment. I temporarily tacked the mags at about .170" from the front of the can with microdots of CA. Once dry, they will be just secure enough to give me an idea of fore and aft placement to center them in relation to the arm

I had envisioned the arm asking me to move the mags slightly one way or the other, busting the tack glue spots, repositioning, and JB Welding them in place using the slug. What I got surprized me, I got lucky and the arm was spaced perfectly with shaft spacers in perfect position. I looked at the up/down positioning and believe it or not it's real close to perfect. It's so close I don't think I could improve it, other than the hole being a few thou bigger than .780. Might not even be a bad thing.

 

If Danny Zona was here looking at it, I'm absolutely sure he'd say, "Grab the CA and start squirting dude". So that's what I'm doing. Sometimes you just get lucky  :dance3:  :laugh2:

Motor assembly was easy; original Mabuchi EB attachment tabs secure the Cox EB no problemo.

Shaft was cut to size for the Sonic steel 7T to mesh with the Parma 27T

She started right up with the click of the power supply, always a good sign of a happy motor  :)

3V, .94 amps. After 10 mins, .84 amps. No vibration, very smooth, no heat.

Rev test, absolutely perfect, no vibration, no heat, no wobbles.

Very smooth and very powerful, another Havlicek home run arm  :good:

Pinion soldered home and the drivetrain test was perfect - motor and gears are very happy.

Balance point test - initially slightly aft of the can end - a tad too rear heavy

1/4 oz Team Associated Iron weight (adhesive patch removed for lower CG) applied - now it's right where I want it, slightly aft of the bite bar

TQ 20 gauge lead wires routed to give soft seft-centering. Car is ready to track test next Saturday

 

IMG_2328.JPG

 

Hand written note from Gene/ZR1 annotates the fact this particular pull came off a genuine La Cucaracha body.

Meaning it had lines on the wheel well edges; therefore I trimmed it as a real Cuc would be.

 

To your eye, it may look weird having the wells bigger than needed for the wheels I used. Or it may look totally wicked   :)  One thing is for sure, this car will run rings around a stock or even a highly modified Cucaracha. I give you the Pablo "Blue Cucaracha"  :hi: Weight is 116 grams

Track test results:

-Perfect right out of the box; no tuning needed

-Plenty of brakes, snappy acceleration, winds out and moves down the straights with plenty of gusto

-Gearing was perfect

-Motor runs room temperature

-Handling was excellent, she drifts real nice with the tan rubber and hooks up fine

-No bad habits at all; a genuine pleasure to drive.

 

Between myself, John Clow, and Red Valentine, we drove it about 40 laps. One single deslot when I overcooked one tight corner.

That's all  :D

Very fast and stable for a car with 2 7/8" real wheel width. I'm cautious with Pablo's one of a kind builds but I would have enjoyed pushing to see it's limits. It had a lot more.
