Nice car & chassis Mark!

Bare welding rod is a bit softer than piano wire, and not as springy. But you've replicated the mantra from back in the day, "use what's available". If you used copper plated welding rod, it should have soldered a bunch easier than piano wire. Nice work.

Yes for sure not nearly as much memory as piano wire. A lot easier to work with. seems to solder nicely and gets nice and shiny with a wire wheel. Curious how it will patina. also not sure exactly what rod it is I got it with a used welder.

A satisfactory test of new build. had to swap the motor as the endbell was so stripped it was falling out. wheel and tire change and it it does pretty dang good. nice handling car.

​It is mild steel most likely. It will rust. Keep it in a dry environment and lightly oil once and while.

Yeah you are correct I came back to another chassis to finish this morning and it had already rusted from acid flux spray overnight. might look kinda cool I like patina’s chassis’

[Mad Mark]

built this car around another body but always mock up junk bodies with pin holes I dont have to worry about. i must have used the same jig spacing because these holes lined up perfect with my pin tubes pretty lucky!

Hey Mark, I usably use the term Patina on non ferrous metals e.g. Brass, Bronze, Sliver etc. The term I use for Rust is corrosion. 

 

There are some coatings for steel, gun bluing come to mind but I never used them. I did find this to add a little info.

 

Is patina the same as rust?

 

In summary, rust is a specific type of corrosion that affects iron and iron alloys, appearing as reddish-brown flakes. Patina, on the other hand, is a surface layer formed through oxidation or chemical reactions, displaying various colors and textures depending on the metal involved.

 

Keep up the builds, love the old school style.

Interesting I just use patina as a catch all term for aged surface. i did go around it with a q tip with some oil to give a light coating per your advice. i don’t mind some rust/patina makes it look actually vintage! And hides poor workmanship on my part. if it was like jewelry like you guys make I’d want it nice and shiny!

You can put a mirror finish on steel with "Mothers Mag & Aluminum Polish" along with some elbow grease. I had a friend who used it on a steel1/24 Slick 7 Eurosport chassis.

Handles good enough to get a faster motor. and some added lead:


Removable dynamic weight:

[Mad Mark]

Some slight changes. French rewind seems very slow. noticed I had to keep adjusting gear mesh and the motor was starting to squeal and act up. went to do a gear change to get more speed and noticed the whole arm wobbling around. the little bushing on the endbell for the arm was totally egged out for whatever reason weird.

Latest build a DC65? first padlock build. trying really hard to think of being 12 years old and it being like 1964-65 to make this as primitive as possible. Pretty tough.

Low slung


Very used elva body. Cool!

[Mad Mark]

So the DC65 car is super slow. like can almost hold it wide open around turns on a flat track slow. is it because it’s the wrong volts for a modern track to run fast?

[dc-65x]

Mark, aside from any obvious binding with the axles or gears look to your brushes and spring. A weak spring or any interference with the brush arms could cause your problem.

 

Pittman 65's, especially the 6 volt variety can run fast!  

 

[Eddie Fleming]

I know little to nothing about this but I understand those motor magnets can loose a lot of there power.

[dc-65x]

That's especially true if the motor was taken apart Eddie.

hmmm I did do a water break in to clean the comm and while running I messed with the brushes and pushed on them a little to see if anything changed RPM’s and nothing changed. gear mesh is very nice and oilites are fine. seems like there isn’t much resistance as far as magnet strength, maybe it’s just old.

[Mad Mark]

When you dont have any dynamic guide tongues or front wheel blocks left

Can anyone ID that body?

The thing that has always attracted me to slot cars is building something unique and seeing how well it will run. Be it built from a few existing parts or from nothing but brass and wire, I just love to see my creations run.

 

I guess that is why I don't get more involved in flexi cars.

Yes it’s very satisfying seeing your creation go around a track. especially when it works halfway decent! i enjoy the whole process.

What do you do with a crusty messed up Astro flex ready for the scrap bin? rainy day resto mod:
