I hope to approach the way that guys like Hanson, Thigpen &c. &c. do it. Pretty tall order, and a very worthy one.

Duffy

I appreciate the comment, but keep in mind I have only been building since a month or two before the first R4.

Just build, with every chassis your designs and work will get better. My first build was an F1, that I would probably laugh at If I still had it. Tomorrow I post a picture of a destroyed version of the first chassis I ever built.

[Mopar Rob]

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

It's all about ROI $500 initial investment and then chassis only cost $4 each.

[kvanpelt]

Nice looking build Rob, please see my post in the F1 thread!

[Rick]

Rob, truth be told. My first mill cost about $900. I have about 3 times that in tooling after the purchase. All I can say, it's a good thing this is my hobby.

[Ron Hershman]

It's all about ROI $500 initial investment and then chassis only cost $4 each.

SO if I buy a Dremel for 50.00 I can save 450 bucks and that will buy about 10 or so chassis "kits" at 40 to 45 bucks each versus spending 500 bucks to get my chassis kits for 4.00 each.

SO is there any value of time spent machine-ing in that 4.00 chassis????

One would think the brass material alone would cost about 4.00 per chassis not including any costs for time and machinery.

Rob, can I still be your friend if we disagree? I like the build very much, and I learned from it.
I have some comments:
1. "simple $500 mill" "CAD" These are things the "average hobbyist" does not have. You implied the "average hobbyist" has a "mill", and now I feel like I'm less than a pinhead.
"The purpose of this organization is to create a rules structure that is cost-effective for the racer as well as the raceways."
This is an IRRA forum - simple soldering skills.

2. "design elements and their legality are inconsequential to this thread" Wrong. You posted this in an IRRA forum, therefore, it is implied to be IRRA legal. Otherwise, it belongs in the "Scratchbuilding" thread. I'm not saying your chassis is illegal....I'm saying it's legality IS implied by it's placement in the IRRA forum. You have an implied responsibility to adhere to IRRA rules when you post in the IRRA forum.

I do love your chassis, and I hope I didn't disrespect you with my words.

No Ron, like most on here it's a hobby. We do it for enjoyment to get our minds off work. If we were performing the work for others who would later make a profit off the work, then a monetary value would need to be assigned. This would be required so some sort compenstation could be exchanged for the service provided.

I purchased two 2" brass strips that I paid little over $8 for and have some still left. I also purchased two 1" brass stips and paid around 6 dollars for. If I would have purchased one more 1" strip we could have had 6 chassis for $17 or around $3 each.


Most people who don't combine their hobby and work would understand

Pablo:

Didn't mean to imply that the average hobbyist had a mill. Was saying they were made on a mill that an average hobbyist could afford. I total up about $150 for an average ProSlot powered retro car built from a $40 kit. Little over the cost of 4 complete cars would pay for the mill. How many slotcars do most people have

This is the first mill that popped up when searching. I'm sure someone could find something cheaper or this model at a better price with some searching Grizzly

I see all kinds of post with people with tumblers, ultra sonic cleaners soldering stations....... it's all about what home shop toys people choose to spend their money on.


I posted in the IRRA portion because it is intended to race. From previous threads I believe the legality came up before and it was said to be legal? Same as others posted about offset Stockcars. If at a latter date if the BOD changes their minds it was still fun and judging by PM's I received it was more importantly informative for allot of people.


No offense taken, I consider you a friend.

[Mopar Rob]

Note:


These parts were manufactured within the IRRA rules


From the IRRA website:

"Chassis parts, such as pans, brackets, guide tongues, etc., that are made using EDM, laser, or water-cutting techniques are allowed only if they are individual commercially-available components or components of chassis kits (i.e. these techniques may not be used in the private manufacture of one-off components)."

These parts weren't manufactured using any of the above equipment and they are only intended for private use. 2 chassis for me, 1 for Bill and the last to be given to one of our slot racing buddies, donated as a race prize, auctioned for bennefit, or just saved for reserve. We haven't decided yet?

[Pablo]

I thought you said "legality are inconsequential to this thread" ?
Now you are defending it ?
I thought it was legal all the way. Dennis S. confirmed it.
Legality is implied in the IRRA forum, and your build is legal. No problemo.

I still don't understand your math, how three $40 kits allows a builder to buy a $500 mill.

[Mopar Rob]

Unfortunately the legality comment was based on too many PM's and was in reference to part manufacture, not the design or key design ellements

Simple Can-Am car cost. Add more for upgrades and pre-painted body. Four Can-Am cars = the cost of the mill. How many cars have you seen in peoples slot boxes?

We do [our hobby] for enjoyment to get our minds off work...Most people who don't combine their hobby and work would understand

Well, I do understand, in a lot of different ways. On occasion I've manufactured something in whatever hobby I've been in, never so much that it's overpowered my recreation--but often it was a close thing.

You're right, there's a certain investment we each will make for our builds; and some of us might find our real hobby isn't the racing but rather the building (I'm dangerously close to that myself, but I intend to change)--and a few will find they love tinkering with the tooling more than the building! Lots of ways to do this, whatever you enjoy.

Duffy

[Pablo]

OK Rob, I understand your math now.
Thanks for explaining yourself.

I like the chassis. I'll make you a deal for the "third" chassis. Send it to me, I'll build it into a complete IRRA legal car, minus body. All new parts, all pablo TLC. When it is complete, I'll send it to whomever you chose.

[Cap Henry]

Thats an awesome looking chassis! I've thought about building a tri-pod car, if you only sold the the pans and nose piece... lol

Bill Worden and I are sending the 4th chassis to Pablo tomorrow.

More details to follow

[DGRacer]

At Skunkworks we call them V-Rails

[Rick]

All in all, Rob nice build. Let us know how it works, on the flat track and the King.

[Mopar Rob]

All 4 chassis kits are spoken for.


If you would like a chance to own one please CHECK THIS OUT

[Mopar Rob]

I had to stop over at Bill's today, so I clicked off a photo of the Sherline 5000 Mill he used to make the parts.

[Mopar Rob]

Two down one to go I built my first chassis with 2 Brass center rails and with the 2 angled piano wire rails. The last one for me will have all piano wire rails.

BTW: I talked with Pablo today. He has some different ideas on what he wants to do. Can't wait until he's off his 7 straight days of work to see his thoughts come to fruition.

Had it on "ONE", for those who don't know is Mike Swiss's king. The car was very predictable and consistant. Did a 5.140 with a junk GTC body, weak Falcon VII, and probably the wrong choice of tires. Judging by last years Sano II times it was in the ball park. Overall I'm very happy with the chassis.

[Mopar Rob]

Both of my Tripod chassis are ready, (almost) to enter my fleet of cars for the Sano III. These have OS Chevron coupe bodies for the GTC class on Saturday. Just need to add my Noose interior to help pass tech.

VERY NICE ROB,

I have not had good luck with the wing stops on the front. I have had better handling with a loose bite bar in the middle or tword the back. Hope they work for you.
