[YetiSRP]

Someone somewhere here had mentioned something about, in so many words, the rationale as to why some chassis' are built the way they are, as opposed to just being pretty.

Well, I present to you The Beast! Actually I just came up with the name after taking a good hard look at it. There was actually some rationale for doing what I did. Not GOOD rationale, mind you and it sure ain't pretty! But I present it to you before I go over a few things on it and plaster it on ebay.

It was designed as a cheater frame! That's right! You heard it! A cheater frame. And I'm not ashamed to admit it (yes I am...)!

It's based on an old Parma brass plate center section (not the Brasskar. This pre-dates it and had a fold-up steel combination u-bracket/upright assembly for the rear axle set up). It has a .032" brass strip with a Yeti steel guide holder on it that sits ABOVE the rest of the frame itself. The idea was to actually allow the plate to float closer to the track surface, thus circumventing the front clearance rule(s). The spring on it was supposed to allow tuning to suspend the plate to clear tech and then air-movement would force the front of the chassis down. Might be able to pull it off if the whole thing didn't weight a ton! Lots of movement throughout the rest of the chassis.

It's an idea that can't possibly work providing any self-respecting tech inspector didn't take the thing and throw it out into the street! Which is fine as I've neither the time nor inclination to try to make the thing work!

But, hey, it's different and sure to give some a few chuckles if not reason to attack me mercilessly!

Jim, that chassis reminds me of a modified Pacesetter center section with Yeti pans.

Are you planning on running a varient of this in the ORS Series this fall I hope?!!

The anglewinders have the new Chicagoland bracket, which is a nice piece too.

Dennis,
Thanks for the props.

Would you mind taking a side shot of the bracket so myself and other's can
see exactly how it's "installed" and braced ?

Thanks

Mike,

Too late, Noose has the frames now!

Perhaps he can take a few close-ups, I forgot to do so.

What I did do on those two frames was to remove the little "tail" on the bracket, as it did not work for the design.

For the rest, it's all standard stuff. The bracket is soldered along the bottom edge onto the main rail, then tacked where it touches the axle tube, and then I ran a piece of .055 along the axle tube and along the front face of the bracket above the holes.

[MSwiss]

That's a good explanation.

I mostly wanted to know (and couldn't quite tell) if
you incorporated the "tail".

[Noose]

I'll take some pics.

[gascarnut]

Thanks!

I thought about bending the "tail" so it would go under the axle tube as a reinforcement, but for some reason that I cannot recall it did not work out, so I just cut it off.

Next time I use this bracket I might run the "Tail" forward as a support for the main rails. Especially on a 1/32 anglewinder with thin rails it might help reduce the chatter problem that comes with sticky tires and thin rails.

[Noose]

Here are the details of Dennis' work. First the Anglewinder bracket.






Here is the Jail Door Bracket:

[MantaRay]

JK Tripod I built for Jimmi B for the SANO. This is like the one I managed to get into the "A" main with last year.
All rails .062. Bite bar .055. Chicagoland Guide brace and a Trimmed BackAgra rear plate.

[Rick]

Just finished with a wee Samurai for a west coaster, possibly an enduro ride after testing?

[Rick]

Larrys new ride for Northeast, almost done............61 grams, can hang a lot of weight on, LOL. Marty Stanley inspired build.

[Craig]

Yet another Gorski Dreams clone. Cap Henry asked me to build him one and here it is.

Pretty much like what I've done for other customers....

Warmack plate
.078" main rails
4.875" overall
.925" motor bracket
.062"x.125" inner and outer pans
.055" cross pieces
Front axle tube as he wants to run bearings

[Robert Rodgers]

New F1 build for the Mason Dixon race at DT Hobbies. .062 main rail and center section. Two piece .062 shaker pan.

That's a slick little beauty!

[miko]

Here is my first scratch build in over 20 years. I thought I'd try something different for a

F1. Still some body mounts & a damper to be added. As you see it, it comes in at 58 grams and is stiff.

Very clean design and very artistic look to it, love it. Miko only 58g's, have you tried it out yet?
Sure it is one of a kind.

In post #509, where can I get that anglewinder motor bracket?

[MSwiss]

I sell that motor mounting bracket (plate).
$2.95 ea.
It does not include the axle tube.

Looks good, Marinko! I love the use of the square tubing; scratchbuilders unite!

[DOCinCanton]

Mike, I will have Bill Pinch get in touch with you.

[spudboy]

That's very different. Thanks for sharing.

[John Miller]

Here is what I worked on this weekend. I'm not happy about the finishes but for 1.5 hours in the vibe they look fairly good. I am going to change media and compound when I get the time and run them again for a mirror finish.

Anyway, the F1 is inspired from Mike Swiss and the Can-Am is a copy of what Howie ran at the Sano. What is that they say about imitation?

A big thanks to Bryan Warmack and Mike Swiss for the assistance.

[Tex]

Nice lookin' chassis', John!
