The drop arm loooks kinda art-deco"ish" when not in the chassis

[Duffy]

Got a reason this afternoon to revisit this thread. Near' couple years on, I'm working on the very chassis I first spoke about in post #1: George Blaha has been campaigning it all this time and doing pretty well by it. It's the central chassis on the desk here -

 

 

- and it's framed by another of mine, also George's now, and in the foreground my current "Borstal" sled. All these are in the bending&bonding style I worked out here.

 

It occurred, here's an opportunity to see how these cars have fared over the seasons of racing & how well my conceits and suspicions about chassis engineering have borne out in real life on the track.

So, I'm gonna jig these up and see if anything's broke, how flat & true, alla dat goo' stuf. I'll tell you as I discover things.

Stay tuned.

By way of follow-up, a Vanity Shot; and not necessarily of my stuff, either.

 

Sooo, I jigged up Blaha's sled (the one on the far end in the pic above) & checked for flatness.

Now, this had just been tuned up a few weeks back, and ten minutes into practice the like-new car had been deliberately slammed by a not-very-nice neighbor. The bracket (not one of mine, as if) was seriously tweaked. I straightened it & re-floated the tubes and guard hoop & drop-fit the axle, and that's all she needed: the rest of the tray's flat and true. Pretty good.

 

 

Now, the Vanity:

It's all Noose's. This is the second Neumeister paintjob I got, & it goes waaay back. Seen a lot of races, and it's still charming. Thanks, Joe.

Brass is slot racer's gold. or sumthin' like that.

Trying to chug along on five cylinders during a pretty bad bout of the Fizzy Hands:

 

 

This is a re-jig job for Shakey George Blaha, the fourth I think for this Duffy Chassis #5 or 7...a real Blas From The Recent, that one. Set down and got as flat as tortured bronze will get, re-set droparm, front & rear tubes floated. Ready for another season.

 

The body's a Lotus 49 from John Dilworth, and as I've said before, who cares if it's a year late, the thing's just too pretty to leave at home. He pops both the "stilts" wing and this "Mandolin" (veggie slicer to you Great Unwashed) style; I mounted it with teeny Velcro bits so he could have fun watching the car go 'round, but then peel the thing off and do serious-like racing.

 

Now, off to do a JD Sports Car sled for Chad Brown.

I'm glad I read that post all the way to the bottom. I'm a happy guy.

Neat little spring holding gizmos Duffy It's nice to see some Jail Door construction going on, Like the details & procedure for soldering up the drop arm pieces.

 

After seeing your brackets in the flesh they are most definitely worthy of the "bomb proof" title  

 

Build on Sir !

Hi Duf,

George has been campaigning that drop arm design for awhile.  He built this beauty that Uncle Fred used to beat a few of the Evil Bucks guys back in the previous century.

 

[Duffy]

Huh! I'll make sure he trips across the picture, thanks for sharing.

[George Blaha]

hey duffy and bob suzuki,

 

Great to see again the uncle fred correnti  winning chassis........He is the master driver. I was a fan of the 26 d and found that it was a easy arm to wind and could outlast the 16 d. It can be seen that the motor is end bell mounted to get more weight to the front  (magnets and armature forward) plus limiting the drop arm  down motion and wiggle reduced by getting the chassis to sandwich the arm. Notice for the contact material, it was not braid but fine lamp wire!
