That's just too cool for school!

[SlotStox#53]

Wow Duffy that's some fancy wire & brass sculpting going on there! Be intriguing to hear how it performs

Very impressive !

[rav7kaa1]

My son Austin( age 15) is in the building mode again. This chassis just off the jig. This is the 4 chassis he has built. 3rd that is scratchbuilt.  More chassis to come.

 

 

10 rails of .047 wire

 

.032 pans

 

3/4 motor bracket

 

1" guide lead

 

63.3 grams as it sits

Good job, Austin!

[Noose]

Great job!

Nice!

This is Duffy #81, "ChernOval" 4.5" Stocker. Built for Shakey George Blaha & based on his sketches & our conversation over some ideas he wants to try out, executed by Duf and yes I did choose my words carefully there.

Mostly .047" wire and .04" brass 'cept .05" in the bracket, just 61 grams as it sits incl. axle so there'll be some opportunity to paint it with lead during testing.

I think the upperclassmen were wrong. Most may look the same, some - don't.

We'll have this out at OCR this weekend. There may be a followup to this story, keep fingers crossed.

 

Duf

Super-cool / innovative design.

 

I love how the main rails take the sharp bend and become the nose pc.

 

And thanks for posting it here on Slotblog.

 

When I spotted it on FB on my phone, I thought it was joke.

 

Not sure on a normal monitor, but at  least on my phone, it's an optical illusion and the rails look like they curve up a couple inches in the air.

That chassis is a work of art, really cool design.

HAR!! Hold that thought.

I'm working up a feature to go into Duffy's Digs on the things I've been doing for Shakey George: the weird and near-weird things he asks for sometimes. Interesting problems, and my solutions made into steel&brass may amuse as well.

Blaha's interesting, and challenging: the guy brings an Old School sensibility to our design conversations, and a racer's eye as well. He's one of those guys that Rocky Russo used to wax nostalgic about, the guys that "see" the car working on the track - and has some ideas on how that work might be done.

Part of the fun is in the stakes he sets out in his challenges: "If it works, great; if it doesn't work, we had a lot of fun trying."

Indeed. Check back next Monday.

That's the great thing about Craftsmen, and the great hope for the future as well: it's in the Genes, and you just can't keep a Craftsman from bringing it out.

Real nice job, especially nice soldering - it's becoming real natural. Let's see more.

Well done Son.

Duffy: Great Googly Moogly!!!!!!!!!!!!

 

If I was was a track owner hosting an oval race, the sadist in me would announce, 5 minutes before the start, that the race would would run in the "wrong" direction!

 

The look on George and Duf's face: Priceless

R-Geo Zee Rail Chassis, built by Rick Jr. Real pretty build. Going on Ebay tonight.................

 

[team burrito]

Jumping on board the tuning fork train, this is my latest F1 build.

 

 

It's 1-1/2" wide & weigh 44 grams; 95 grams fully loaded. That's 25 grams lighter than my regular race car.  Here's a close-up of the renforced rear end.

 

 

I boxed in the axle tubes with some .016" x 1/4" brass.  One of the weakest parts of most every chassis is the axle tube; this should make a little more durable.

 

 

I tricked out the front end a little by french-cutting the front supports. The pans are soldered directly to the front nose; movement is through the front tubes & rear keepers (see above).  Will it work?  We'll find out when I take it to Frank's tomorrow.  Later.

Here's a followup to post #1750, a quick capper to George Blaha's ChernOval lefty stocker:

It did pretty okay on Orange County Raceway's perverse little Quad-Oval, in some perfectly horrible traffic! This track has two left kinks in the back that are real hard to get  a rhythm on, and just surviving eight heats was an accomplishment.

George finished third in his B-main, & sounded pretty happy with the car's performance. Both mains were nonstop conflagration and everybody got collected in it more times than you'd count, but it seemed like this chassis handled the abuse; it took one real hard wallshot that changed the handling - I haven't heard what got knocked yet - but he survived.

So in some way that's proof of his concept. Like I say, I was just the welder on this one. I dunno what the heck's in there.

 

I drove the TonyP car in the other half of the pic, and the car was great & I was- meat. Apologies, Tony.

Russ,

 

That F1 is gorgeous! Please let us know how it works.

[usadar]

 

Maybe it has been discussed already somewhere else, I would like to know whether this tuning folk construction is legal at IRRA or SCRRA if the two hinges in the center are not soldered.

 

My intention is not to make this an issue in understanding the regulations but to make it sure it is legal or not before I build my tuning folk chassis.

 

By the way, this F-1 is a great build, Russ.

 

Thanks in advance,

 

Haruki

[Greg VanPeenen]

Haruki,

 

Mine have been run in both IRRA's with no problem, Being that the hinge is not on center and is at only one end of the tuning fork rails I guess. I am just getting finished with one that will be going west soon.

I like your builds a lot.

Did it win? Did not see the follow up story

[Duffy]

I put in a quick word in post #1767, Ray:

George got the car onto the podium in his Main. He was happy with it (proof: he paid me), was vastly amused at how I'd developed his simpler concept into this "art" (his concept wouldn't've got through the first heat, I tho't), and, hey, everybody had a laugh or two in a day of mixed laughs and screams.

I'm burned out, though. Back to good ol' basic Duffy-builds for meee.

[Half Fast]

Duf-

 

Having a creative concept is good, but you need the skill to bring the concept to life.

 

The ChernOval chassis just radiates great craftsmanship!

 

Cheers

[Duffy]

Awwww, you're makin' me blush. Or maybe I should check my dosimeter.
