Topic: The NASTE chassis!

Alright guys, I am making progress on getting the Scholer Pantera model loaded into CAD.

I want to get your guys input on necessary changes to the design to better suite our cars and builds. Here is a list of the changes I already plan on employing. Let me know if there are any other changes you think would make this the best bet for us.

1. The main brass plate will be made out of .063 brass plate, so shimming for pans will no longer be necessary.

2. All hardware will be switched to 2-56, I can get 100 SS screws for $6.

3. H-plate for body will be made of steel, to resist bending and need to reinforce.

4. All brackets will be 18ga mild steel, I will probably plate them to resist rust.

5. Bearing bores will be changed 1/4, to allow direct installation of 3/32 bore axle bushings.

6. Motor cooling hole pre-cut in chassis main plate.

These are the plans. I will be producing 1 prototype with the necessary changes as soon as the file is ready, then going about trying to price them to be manufactured. I have a target goal of $75 for the kit.

Re: The NASTE chassis!

That all looks good to me Zack!

Re: The NASTE chassis!

Sounds great Zack! Please check to make sure the wheel base can go to 4.5", I don't remember if the chassis I loaned you can stretch that far, I think it is good, but you know.................my memory fades in and out!

Re: The NASTE chassis!

The car is all loaded up. We are going to make some small changes after a pow wow last night.

1-All of the extra holes in the chassis for the suspension front end will be removed from this model. That will add weight to the chassis plate. You can always drill your own if needed.

2- There will be a clamp piece made for the tongue instead of 4 screws, so that it can be used to reinforce the guide tongue

3- The side pockets for the pan will just be rectangular shaped, so making pans that fit will be much easier.

4-Instead of 1/4 diameter bearing holder, we will be going with 3/16. Since that is the standard OD of most ball bearings and bushing for 3/32 axles. This way the bushings/bearings can be installed directly.

5- All parts and brakets except the main plate will be made of 18ga steel, including the H-plate body mount.

Getting closer!

Re: The NASTE chassis!

FYI>>>>chassis is adjustable from 3.8-4.8" the way it is currently configured.

Re: The NASTE chassis!

AWESOME!

Technically this would be the NASTE Chassis II........if so designated.....

Done.

Re: The NASTE chassis!

Here are some drawings showing the max adjustibility of the chassis. For reference.

Some of the things you will also find nicer about this chassis, is the fully blended smooth corners on all parts!

Re: The NASTE chassis!

This looks like a well thought out improved version. 3/32 bearings are 1/4" OD I believe without looking. Using durable steel in the critical areas is a big plus. Brass provides good weight but usually needs wire re-enforcement. Good job on trying to provide a production kit that doesn't need a lot of mods!

Oops,  3/16 bore is correct.

Thanks Dennis, I think it will be a solid improvement all around. But not so much that the old cars are obsoleted.

Re: The NASTE chassis!

What I like about what Zack is doing:

#1 veteran racers and new racers alike will not have to look on line or wherever to find a legal ( for Rapid Raceway ) chassis any more.

#2 The chassis is going to have stronger parts such as the rattle pan, guide tongue, axle brackets. That is a big plus!

#3 American nuts, bolts, axle holes etc. YES!

#4 This chassis is good for 4 classes at Rapid Raceway ( TA2, NASCAR, NASTRUCK, Porsche 962 ) so if you want you can use this one chassis by adjusting tracking and wheelbase and maybe pans. That is also a big plus if you don't want to spend unnecessary $.

Can't wait to get my hands on a 2NASTY chassis!......................................................... Poetry in motion!!

Re: The NASTE chassis!

We are getting close on the drawings. I am hoping to have a prototype in less than three weeks!

Zack

Re: The NASTE chassis!

Alright guys. I have ordered the first 2 prototype chassis today. There are still some details to iron out, but I am hoping to have one of them functional by the weekend if all goes according to plan.

Right now it looks like pricing should be pretty good!

Zack

Re: The NASTE chassis!

AWESOME!

Thanks Zack!

Re: The NASTE chassis!

Great news Zack! Looking forward to seeing the real deal.

Re: The NASTE chassis!

Great news- well done sir.

Race cars are neither beautiful nor ugly. They become beautiful when they win.

Re: The NASTE chassis!

The prototypes have SHIPPED! Pics coming next week.....just got to get them formed up!

Hopefully they work great out of the box and we can get to work filling orders. We are currently up to 11 pre-ordered!

Zack

Re: The NASTE chassis!

Zack; you are up to twelve for sure chassis with 2 more possibles according to my list and that is not including you.

So we are!

Zack

Re: The NASTE chassis!

The prototypes are here.....Now to find out if they work!

I have some tapping, bending and countersinking to do and then we can see how they stack up.

Re: The NASTE chassis!

Looks good from here Zack, I zoomed in on it and I can see it is stronger than what we have. Looking forward to putting one together and dialing it in!

Thanks for taking the time to do this.

Re: The NASTE chassis!

Yeah i am happy with the choice of material. I think it will be a big improvement.

Zack

Re: The NASTE chassis!

Progress report. I made an error bending the first chassis plate, so I am hoping to complete one chassis out of the remaining prototype parts.

I got the correct countersink from McMaster carr. This is hand tapped 2-56 (TINY), and bent on the press brake in my shop. So far so good!

Hopefully this chassis will be in a running state next week, and I can get one of these guys with a big track to let me in and do some testing!

Re: The NASTE chassis!

Looking good Zack. Call me and we can make arrangements to meet at my track for testing if you want.
