New home for the Havlicek gear-stripping powerful armature

Slick 7 ball bearings at both ends, hoods cut for shunts, and perfect alignment. It passes the "shaft falls through the hood bar under it's own weight" test. Now, where did I put those doggone C can magnets ?

Chassis planning: 

Wheelbase 5.125

Guide lead 5/8

Rear wheels .875 OD, width 3.40

Front wheels .8125 OD, width 3.08

Clearance rear .063, front .032

 

Note small strip of plastic super glued to dummy axle, this will give the jig motor some clearance from the axle. It's hard to see in there when you're setting the motor angle.

 

I tried a new idea, super glued the jig motor onto the jig at the exact angle and position I wanted.  Once it was secured, I was able to remove the actual pinion and spur I plan to use on the completed car. No sense getting acid on them.  I also spent some time finding the approximate balance point of the motor at the angle I will use, to hopefully have equal left and right weight distribution.  On this motor, the balance point appears to be somewhere real close to the hole closer to the endbell.  So that is how I placed it.

 

Time to plug in the Ungar  Wheeeeeeeeeeeeeeee !!!

Nice logic on the motor balance/placement Pablo Fire up the Ungar

I think the wheels are gonna look real sexy on this car, JC.

 

[SlotStox#53]

One sexy looking Batmobile Pablo ! Those wheels really finish off the look. Should prove a fast mover to get the caped crusader round the track.

 

Look forward to your track test report on the handling & that hot arm'd motor

Great stuff, Pablo.

 

You need your own subforum... oh, wait, you've already got one... LOL!

Inner rails, rear axle tube, and nosepiece.  Owl Chump style !

[Gator Bob]

Pablo,

Was the Owl Chump style chassis originally designed by Al Chuck?  

[Pablo]

Rick Bennardo, I am mad at you.....this doggone jig won't support a 5 1/8 wheelbase.

The build is going slow but smooth.  Thanks a million to Rick Thigpen's excellent photography in his thread. I've made some mistakes but recovered from them, so far.

Rick B, I want a full refund.  Just kidding, please do not change this jig, it is a true masterpiece.

Pablo, you could always split that jig in two with the new bandsaw, like they do a womp chassis, then lengthen the pieces with piano wire or square brass tubing to increase the wheelbase.  

 

Maybe you should have built this chassis on a drag chassis jig.

Anyone?

[Pablo]

Hi Bill   That's not a bad idea.......but Rick's Jig is so versatile, it will work fine

Front axle settings are set, ready to lay some .0625 Iso front rails. I have never been a fan of front wheels in any type of car, so this design is perfect for my taste. The wheels will float on the track surface with a slight amount of downward pressure via a .032 spring wire, just like the dc-65x Owl Chump car.  His used a 1/8 axle inside a tube; mine is 3/32 sans tube, front wheels will rotate independently. Not saying mine is better, just sayin' it's different.  Mine is a BATmobile  !!

[Pablo]

How am I doing here, Rick T. ?

[dc-65x]

She's a beauty Pablo......very ISO BAT-Winderish

[Pablo]

Thanks, Rick   Man, I love these new tools !!! Pans were a challenge on this car, as the sides of the Bat body are very oddly shaped.  First, I traced the outline on paper, cut it out. and marked the widths.  Then transferred the outline to the jig and marked the pans. Freehanded the Band saw rough cut then used a combination of disc sander, Dremel sanding wheel, and 400 wet/dry sandpaper to make a nice form fit.  Now all I have to do is go full plumber with them.

[Bill from NH]

Those pans got more curves than Marilyn Monroe.

[Gator Bob]

They look 'pantastic'.  

[SlotStox#53]

Looks like it's coming along very nicely Pablo   Those pans are a work of art! A bandsaw looks the perfect new tool Think I'll be sticking to oldskool , nibbler ,dremel and the trusty file

[Pablo]

Paul, I don't know how I worked without a band saw for so long.....

 

Anyway, had to call in a plumber this morning.....055 wires inside the tubes for a little lift and wiggle.....

[Bill from NH]

Pablo, what's that guide tongue? It looks pretty hefty.

[Pablo]

Sir, that is a Cobra tongue modified to fit a Jet Flag, sitting atop a chunk of .063 brass strip, with 10 thou lift in front to allow for the 063/032 clearance rake.

All plumbed up and ready for pans:
