Some very cool stuf going on here. Pres, some guys are currently talking about how the center-mass concept is well worth exploring. Play with it.

Ohhhhhhhh Tex...yah, when you screw down something, something's gonna get stressed. Don't give up on the idea, but figure out what's pushing on what where, & think about how to get that to do what you want without thhe collateral damage. You are developing a regimen of VSWT here, and the final iteration will not spring out full-grown and entire like some Hindu deity, it'll grow.

Per Geo. Blaha's RetroPro chassis in post #1149 (and, by the way: the "wire wraps" on the front axle aren't wire, they're two bits of strapping tape! This was the "Vanity shot," and the axle hadn't been assembled w/ tyres and set at height yet) - George dressed it up and gave it a shakedown run...and, with the wrong gearing and not a lot of tyre-testing time, he was very happy witth how it ran. A couple more sessions before next weekend, and it's going to the Fall Brawl.

not only am I confused, my eyesight is poor!

Another great build Preston! Why did you use lead wire insulation on your bite bar?

A motor is only as fast as the chassis it's in.

Thanks Tim. I was unsure of how my joints were going to turn out. My weller gave out on me, so i bought a hakko. The iron works great! and since the tip is much smaller than my old weller, it is a bit easier to control solder flow.

Looks nice, P.

I suggest you get the small chisel tip for your Hako, you'll like it (if you haven't already).

And nice putting a face to you at the FB.

...And here's a guy so terrified of solder joints that he'll bend wire right around 'em to avoid making more.

Duffy 65 Gilded Splinters 04.JPG

This is the second Gilded Splinters iteration, going from three courses of .055" wire down to four of .047" for a more supple twist. Interestingly, these chassis show very little lateral flex, or yaw.
I should do just one change at a time with this stuf, but I couldn't wait: went from the original torsion to a shaker perimeter.
We shall see.

Duffy 65 Gilded Splinters 05.JPG

By the way, to followup - I gave Gilded Splinters ver. 2.01 a good workout in Can-Am at the Fall Brawl; the car worked very well on the smooth SZ Engleman; didn't get me any faster, mind, but it let me drive as fast as I was able with no surprises! And a couple of the really good guys played with it and pronounced it not lacking. Okay.
It also survived some rather brutal takeouts, including one significant wallshot that scrunched a bearing and the rear axle stackup, leaving me with a squirrelly two last heats; but the chassis itself jigged back up just fine with no tweaks. Okay, again.

More when I have some news.

Duff, that thing gives me weird eye as I try to follow the pieces around corners, then more corners, and a couple of short and long chutes thrown in between even more corners...... Incredible!

The lateral flex is resisted by the taper. My tripods had/have virtually none.

Next time we're at the same track at the same time...... mind if I look at it and.... touch it?

Nice meeting ya at the FB.

Great build Bobby!!!!

This is exactly the use of FSF chassis/components that we intended. Buy, design, cut, assemble, WIN!!!! The kits do not have to be assembled as they come in the kit. You can also design your own kit from all chassis/components that we make.

Very nice Bobby,

As always ..very tidy build Bobby ...im sure it will be a quick one ..very few, if any, in your box aren't.....man you build clean ,neat cars. As a novice builder i appreciate all you men posting builds.There are so many different ideas that retro will never stop evolving.
I do see a swing towards the "kit" concept ,that of starting a chassis with some sort of pre-made brass pieces.Almost [think i seen2 "real" scratchbuilt ] every car i raced against yesterday was started with a pre-cut pieces of some brand.

Wow 4 0.47 main rails on a X25, that is going to make that chassis very stiff. just going from a 0.68 main to a 0.72 makes the X25 alot more stiff and looser.
Let us know how it works.

I used 6 .047's and it is wicked fast on Thazers hillclimb. It seems the 047 wire gives a little up down flex, but almost no side flex or "rear stear" as opposed to the 0.78 which seems to be stiffer in the up down direction, but still has side to side flex.

In preparation of the Checkpoint Cup just around the corner I've finally found some time to build the car I will run in the Can-Am race. Another Kamo-Speed clone however, with lighter outer pans. Kamo has used .1875" on the builds he has done. Mine has .125" for just a tick less weight.
