Hi Rob
Looks really interesting!! Hope it handles at least as good as the car I borrowed from you on my visit to Chicagoland Raceway!!!

[Mopar Rob]

Had to bend all the wire I needed. Can see benefit in having a separate bender like the R-Geo. Probably wouldn't normally be a hassle, but I bent up wire for all 4 chassis'. AutoCAD provided all the wire dimensions so all I needed to do was set the bender and bend.

Set all the pieces in the Jig. This isn't how I normally build, but the angled wire added a new dimension to the build. Had to use tape and the hold down. This is my friend Bill's chassis. He wanted to use a WRP guide tongue and the JK hypoid bracket. Only took an hour to set everything up Now off to tack some pieces together and do some serious soldering.

Soldered the center together. For those of you like me who don't have a tumbler, I just use a SOS scouring pad.

Looks excellent Rob, The thin brass nose piece looks like it may not survive me falling off in front of Bill...lol
Looking forward to see how it runs.

You telling me I should have made it from .062 Brass and not the .032 the pieces were made from? I'm not woried about tearing them up before the Sano, I can aways just race out of Dave Creavie's and your box again It was allot less work on my part doing that.

I think when Ray was referring to the nose piece, he meant the guide tongue.

Mine will have the Chicagoland .042 spring steel tongue.

I still would rather race out of someone else's slot box.

Anyway, back to the build. Soldered the pans on. Would have liked them to be a little cleaner, but have an 8 year old who "helped" me with build.

Rob,

Lookin' real nice! I have a question: Were the brass pieces CNC machined, or did your friend follow your drawing, and do them by hand?

Rob,

Thanks,

These were made "old school machinist" (red dye, scribing lines using calipers.....)on a something like a $500 Micro-Mark Mill from a drawing of just the pieces with a bunch of dimensions. Even though it would have been easier to CNC, Waterjet or at minimum use a Mill with a digital readout, we wanted to make them with equipment that an average hobbist had at their disposal to show what could be done.

[MantaRay]

Mr Swiss............Thanks for clarifying

Once again, Great build Rob........

[Mopar Rob]

All finished, or at least the amount I'm going to work on this chassis. Bill can put wheels, motor, bearing..........to finish it off

Now off to cut my grass and eat some lunch.

Later I'll start on my build. Don't know if I will post or not?

Looks good.
It looks like that front axle is going to stay on.

I like that you let your son use the soldering iron a bit.
I won't even check into the Somonauk child labor laws.

[Mopar Rob]

Thanks Mike.

I designed it to be robust. Tearing up a car in practice on Saturday reinforced that robust designs are good


Not too bad for a couple of hicks living out in corn field country 60 West of Chicago?

[MantaRay]

Rob, It
looks like you got that soldering iron very hot!
Hey....Nice joints........lol

I'm not sure if having the 2 straight rails tie into the front axle and motor bracket are a good thing? I figured it would either make it strong or take out the chassis in an accident. I guess time will tell?

Decided to weigh it before it is totally built.

61.9 grams

[Dominator]

With the way you have the front axle supports and the wire ties I doubt you will have any durability issues with the front end. Really nice design. Did you use .055 wire all around for the rails?

[Mopar Rob]

Really nice design. Did you use .055 wire all around for the rails?

Thanks,


I used .063

I'm building another with 2 piano wire and 2 brass .063 wires. .055 isn't a bad idea for one of the others.

MODERATORS:

Bill and I intended purpose of this thread was to show that professional or purchase finished quality parts / chassis could be produced with a simple $500 mill available to most hobbyists. We wanted to provide inspiration or challenge those who already have the equipment to take it to the next level. For those on the fence thinking, "I would like a mill but what can I make?" it was a demonstration of the potential. While the drawing was produced using CAD software the same results could be obtained with pencil, paper, calculator and basic drafting equipment.

That being said the design; key design elements and their legality are inconsequential to this thread. We are asking that pontification posts about it's legality to please be moved to the IRRA rules discussion thread before it expodes to the point that the thread requires being "closed"

We also believe that those who contributed their builds, tips, or designs are value added and should remain and are appreciated as they provide or challenge thought to future creations.

Thank you,

I think I strained some neck vertebrae at this one. Half a grand, simple?

Well, I'm a tool & die maker & I've been reading along with this thread, all the while plotting how I'd do it at HOME. I may machine a tool now and again for myself, but mostly I want to leave the machinery at work. That's just me. Maybe having CAD/CAM available to me makes it easier to disdain home-shop stuff. Pretty provincial, if that's how I'm thinking.

The great thing about this build is, it got me thinking in some very interesting new directions, and I'd reeely like to go at one with Moto-Tool, nibbler, & file!

Thanks for putting it all out here.

Allthough I do not have a Mill as of yet, I do have a Sherline lathe that could be converted to a mill. Yes it would be pricey no matter how you go about it. My point is that I appreciate this thread for a different approach to the build. I constantly review all these threads on the blog and have picked up countless tips and tricks and ideas from many posters that are willing to share their builds or just pictures of a finished product. I have been watching this thread as well and I am now more curious to here about the results of when the "Rubber meets the Road" so to speak. Cant wait to see the next few or more that people construct based on this "Mike Steube" inspired build.

Keep em comin Rob!

[Duffy]

Nicely put, Rick, and very much my sentiment as well.

I don't have street cred here, but I do bring a bit of craft to the discussion--and one of these days I will put up some work to share; and I hope to approach the way that guys like Hanson, Thigpen &c. &c. do it. Pretty tall order, and a very worthy one.

The guys who don't want to spend 42.00 for a motor because they cost to much are lining up to buy a $500 mill to build a chassis with. LMAO
