Gizmo is dc-65x's generic name for a whole bunch of different tools. They're all related to a thing-a-ma-jig.

[Pablo]

Some small details are done:

-orange donuts are glued and curing

-Gold Cup flag shaft has thin wall tube secured

-flag tube is cut to size, polished, and elevated above the block .088"

-Wildcat endbell holes tapped 2-56 (I just love saying it - Wildcat  )

-iso hinge wire holes drilled in bracket sides

 

Jigged up with first rails tacked. Forward crosspiece is just temporary to secure the rails for now

 

[old & gray]

IMHO the only good Castleton bracket is one Pablo or some other craftsman has spent hours working over! Otherwise they are junk.

 

 

Now I understand why  a kid with a Weller gun, a couple of files, and a hand drill had so many problems getting a chassis to handle in 1967.

[Pablo]

I get your point, Bob, and agree only partially. The pros back then didn't have many special precision tools but managed to make them handle.

 

 

 

The trick is knowing where poor tolerances will and won't hurt performance.

Example; I doubt having an inline motor cocked to one side a little would make any noticeable difference.

 

Mike Steube, in his retro building video, points out some of his best retro handlers had flaws, therefore didn't insist everything be exact.

Of course there are things that HAVE to be perfect - low CG, strong solder joints, amount and location of flex, etc.

Things like a downward tilted flag or parts binding are just a couple examples of instant handling killers.

I think that's what my old and gray buddy refers to.

 

I spend lots of time getting these things perfect because I have the time and I enjoy it.

By the time one of my cars gets tested, I pretty much know it's going to handle - the benefit of precision.

 

 

Back in the day, the pros could build one in a matter of hours.

Even today with all my special tools, if you told me I had a night to build one, I couldn't.

It would take a lot more than a six pack of Pepsi and a pizza for sure

 

Enough talk - where did I put those doggone .062 axle keepers ?

[Bill from NH]

The pros back then had the Russkit jig.  

[Pablo]

I think that's enough main rails

 

[Pablo]

Added some weight to the front end. If it needs more I'll just slap a piece of lead or a Classic weight on top

 

[Pablo]

Originally I planned to round off the front corners but decided against it.

The "square" front end kind of grew on me, so it stays. Love it or hate it

 

 

Sleeved Gold Cup flag with two Koford spacers ready. I'll start with one.

Attention to detail - I didn't just assume both spacers would fall free over the sleeve to sit flat on the flag deck - I checked it - normal procedure

 

[Pablo]

With the exception of flag stops, center section is done

 

 

[Pablo]

2,000 grit sandpaper mikes about 6 thou. I used it to space the twin .063" wire Iso rails while tacking the hinge gizmo

 

[Pablo]

Hinge wires managed by .063" keepers butted up against bracket sides

 

[Pablo]

Using keepers to manage the Iso hinges worked pretty well, eliminating the need for a cross-connector to prevent spreading

Pablo. a clean looking chassis design so far! I want to watch how you attach pans or outriggers. (Hint) Pans could be made of brass rods too.

[Pablo]

You mean like my Jupiter chassis ?

 

 

That's a good hint, Bill, my plan is definitely brass rod. Stay tuned.......

[Bill from NH]

That one looks like it could have been built by a drunken sailor.  

[Pablo]

Beauty is in the eye of the beholder, Bill

This Ferrari chassis needs to make the (curled) body skirts behave and I'll do the best I can.

I transitioned the Iso piano wire rails to brass rod with .047" spacers. From here on it will be all brass......

 

[havlicek]

Schweet!  Last time I saw that much brass, it was in High School band!  

 

-john

[Pablo]

Should look nice with the yellow Wildcat, eh John ?

[Pablo]

My method of dealing with the curled body skirts:

Upper and lower .063" outrigger type rod pieces with mounting tubes sandwiched between.

Upper rod is slightly inward of the lower rod and mounting tubes are slightly indented.

Nothing but rounded surfaces will touch the body

 

 

Iso stop - it only takes a hair of movement to make the design work it's magic - I used a sliver of 400 grit sandpaper when I tacked the gizmo on

 

 

Time to put a chassis in the tumbler and a ham in the oven for Christmas

 

 

 

Merry Christmas everyone

 

[dc-65x]

 

.........and a ham in the oven for Christmas

 

Merry Christmas Pablo and you and your "little buddies" take it easy on that ham!

[Samiam]

WOW!

 

That is one classic looking chassis. Love the " All rod...Nuthin' but rod " theme. Nice.  

 

Merry Christmas

[Eddie Fleming]

Merry Christmas Pablo.

 

Great looking sled.

[Bill from NH]

A+++

[Pablo]

Thanks everybody

 

 

 

 

 

 

[dc-65x]

Your building skills and that Mississippi water in your tumbler sure make for a pretty chassis!
