Okayso… been busy the last few weeks.

 

There is a fair bit of new development/experimental stuff here (and more later) but also some fairly basic cars. As mentioned in the NorCal forum, I get repeatedly asked for frames or cars and am always willing to take orders but a lot of times, guys just want ‘em now. So... some of these will be in raceways showcases soon (some already are).

 

No step by steps here b/c the basic stuff is pretty much that... basic. There are of course some variations from prior cars shown here 'cuz each of my frames is different. The weird stuff???... heck... I don't even know if it'll work....  :wacko2:

 

--------------------------------------------------------------------------------------------------------------------------

 

Here is a 4.5” stock Car. Pretty basic frame, but this is the most proven and winningest design. This will be avail at FTH. With bearings and fronts.

  • Single rail .078" wire.
  • R-Geo Bracket, cut-down JK nose.
  • Brass corner weights all 1/16”.
  • This will finish up at about 105 grams without body.
  • Probably too light for most racers and suggest 5-10 grams additional weight.

This is a Can-Am that’s in my fleet but FTH has a three-rail/.062" version. Good general purpose car.

  • Four rails of .055" soldered.
  • R-Geo bracket and steel guide.
  • Handmade nosepiece.
  • Running weight about 105 grams without body.

F1, good general purpose car. This is going to FTH, but Motown has one like it right now. The one at MT is a two- rail, one rail each of .062" wire and bronze.

  • Three rails, one of .062" wire, two of .062" bronze rod.
  • R-Geo bracket, handmade nose.
  • Running weight ~ 102 grams without body. Some may want a center weight for flat tracks.

Can-Am not so basic. Multi-rail, will be going to MoTown as a RTR, probably sans motor. MT already has one like this in frame only that’s a five-rail.

  • This is a six-rail/side of .047" wire.
  • R-Geo ¾” bracket, handmade nosepiece.
  • All pans and weights are 1/16” brass.
  • This will equal about 111grams without body and will probably not need weight.

Can-Am, sorta basic but pretty different rail setup. This one is in my fleet for testing. Looking forward to MoTown with this one.

  • Four rails, two of .055" wire and two of .062" bronze rod, with space between the two rail sets.
  • R-Geo ¾” bracket, Warmack tongue, handmade nosepiece.
  • The rails are not full soldered at this time but may end up that way.
  • This will go about 104 grams without body and should be a good, forgiving car.

OK… now for some weird stuff...   :laugh2:

 

This Can-Am has been in the thinking stages for a while. I wanted some elements of a GT12 frame and also a way to suspend weight independently of both the pans and main chassis section. I wasn’t 'zactly sure how to do all this until I saw a pic of a perimeter frame by Bryan Warmack that helped to coalesce my thinking and kicked off the project.

  • Main perimeter rail is .055" wire, tuning forks are .062", diagonals are .055".
  • Handmade nosepiece, Warmack ¾” bracket and guide tongue.
  • Rear triangles are .062" and are soldered at the rear perimeter but not to the fork.
  • Body mount tray uprights are .032" brass connected by the front pin tube and one spreader. I think there’s probably a better way to do all this.
  • The body mount “tray” does have fore-aft movement but it is relatively minimal.
  • Weights can be suspended from the diagonals at about any location imaginable.
  • This will go about 93 grams without body and will probably need weight ^^^^.
  • I have hopes but uhhhhhh... this may be a loooong term project.

Here’s a new F1 that is a spin off of a “Z-rail”. I have built a few Z-rails and had good success only with one F1. However, that car won the race the first time out but was never really great after that and I eventually scrapped it. This one takes some elements of the pure Z-rail concept but changes them in favor of a little more control over the flex of the rails.  

  • All the rails are .055" wire.
  • ¾” bracket and nosepiece are R-Geo. Built-in uprights on the stock nose are bent outwards roughly ¼”/side.
  • Inside .055" rail is soldered front and rear.
  • Center rail is doubled .055" soldered together and soldered to the main rail only at rear, but floats at front (red arrows pic #2).
  • Center rail floats at front but with a downstop (red arrow pic #1) and upstop (red arrow pic #3).
  • Outer rail is soldered only at the nose (blue arrow pic #2) and is captured in a 3/32” tube at rear (blue arrow pic #2).
  • Pans are suspended at front on a .047" hanger going through 3/32” tube.
  • Pan is soldered to outer rail right at the entry of the rail into the rear tube.
  • This will go about 105 grams without body and the 10 gram center weight in place.

I've also done some new anglewinders but there's not a ton of widespread interest in those. I have been axed for some detailed pics of anglewinders and I will do some but I need to test them first and then strip the running gear for better photo clarity. That'll be a week or so.

 

Testing soon...

Some great work there, Jim.  :good: All look fantastic, especially like the perimeter experiment.  :D

 

First class.

Beautiful chassis, Jim!!!  One thing I would check is the guide lead on the Stock Car chassis. 3/4" is the maximum legal limit.

I've been building weird stuff too. This is my light-weight version of my K.I.S.S. (Kinetic Internal Suspension System) F1 chassis:

10409546_845590195469881_371242382797240

 

The MkII chassis worked fairly good at our last race on SCR's blue King, so I thought I'd build one for banked tracks only. I'm aiming for 90 grams, less the body. I'm swapping out the heavy metal wheels for JK plastic rims.

Jim, Russ both of you guys do such great work. I'm looking for a chassis for my 1/32 Bentley EXP Speed 8. Which one of you guys can make me a torsion bar chassis for the flat track at SCR?

Thanks, Mike! In NorCal we have never had a guide lead limitation. IRRA® is different of course.

Thanks, Dom!
 
Uhhhhh... which one? I suspect the GT12-ish one and I was all jacked up when I finished it, too. I have no idea if it'll work at all but that's why I do the goofy stuff. There is plenty of more conventional stuff that I know will work.
