Nice work Al! On the previous pic, the chassis and gear plate are so modified I can't tell what they were to begin with. Nice snap in rear axle.

Is that a tungsten plate that is glue to the front chassis?

You are using torsion spring on the pan system. Have you tried just a free float rattle system?

Nice work Tom. The Nats in Boston is 4 weeks away. Change of Director seems to led to it not getting it posted here. I will work on that but for now as late as it is just google HOPRA slot cars and it comes right up. Oh yes I love my Starret stuff.

Mike free floating did not work for me. sitting flat there is no load in the wires. Only in rotation.

All these scratch built H.O.'s are really neat. I do notice one thing is that many do not seem to have any traction magnets? So where are they getting their traction from? Do these even compete with a Super G+ or are these just fun cars that are just not fast enough that need traction magnets?

They are referred to as gravity cars, and purposely have limited magnetism, to drive more like a 1/24th car.

I was out of slots from 1977 to 1987, and when I came back over the next 2 years I made these.  The one on the left I think was an eyeballed copy of a chassis that appeared on Car Model magazine, maybe one titled Lead Sled if I remember right.  Never quite finished it up with wipers and was short a knurled rear axle at the time.  The middle one used a surplus type long stack arm can style motor and brush system like the Tomy cars of that age, rewound with #37 wire.  The now yellowed note I made on it stated it was cool running yet had higher torque and rpm's than a stock Riggen and pulled a bit over 1.7 g's on a circular test track.

 

The car on the right has a similar type motor and rewind but was fitted with 4 ceramic traction magnets, with a printed circuit board phenolic material used for the main chasis material.  Cornering speed was noted as equal to a Tyco 440x2.  The motors, circuit board material, and I think the traction magnets were just stuff I found at a local surplus store, just to see what I could make with them.  I have some other old builds going back to the TJet era but many were also made as experiments, not necessarily as speed demons or works of art.  Some were closer to Rube-Goldberg type devices.  Might post them on a separate thread when I get around to rounding them up and taking some pics.

My descriptions mixed up the order.  The mostly phenolic chassis with traction magnets is in the middle, and the one on the right is brass with no traction magnets.

Traction magnets under the wipers? What inspired that?

Probably nothing, other than trying out a 'more is better' idea and maybe wanting the front wheels to make firm contact while still giving good wiper/electrical contact.  I never did organized racing, I was just an experimenter trying random things.

Come to think of it, the traction magnets may not have been ceramic, they could have been older more standard technology.  They were whatever I picked up at the surplus store, unlabeled.

With the front traction magnets I may have also been thinking along the lines of the early AFX magnet cars where people were using a pot holder type bar magnet under the pickup shoe area, in addition to the rear ones.
