New Unlimited

[Guest]

Well, it's finally done! I have worked little by little on this car for the past few months. The main goal with this car was to come up with a new design for the way we use the bearings presently. My goal was to come up with a way to get the bearings out of the rear wheels and into the body somehow. My 1st attempt was with a plank style body but was very hard to accurately drill and ream for bearings in a wood body. I did get it to work but was not happy with the way the wheels were spinning. So I scrapped that whole car and went back to the design board. What I came up with is the car below. The car consists of (14) pieces that were all hand machined by myself. The rear of the car houses the new bearing design. It's hard to tell by the picture but the wheels have no bearings in them. There are only (2) bearings in the rear and they are both in the aluminum axle tube. In order for the design to work I also machined a custom 1 piece axle in the rear out of some aluminum rod. My plan is to give the car a test next weekend at my buddy Zeeb's house. If it passes the test then it's on to Kentucky for the CFC. As much time and money as I put into this, I sure hope it's not a dog.

That is the coolest thing I have seen in a long time!! The only thing that I could think of that would even possibly slow it would be the rotating mass, if it is greater than that of just the bearing and wheel combo. Win or loss that thing is awesome!!!

Are the rear wheels locked together? Will it require less drift or more.

That is great!!! if this pans out for ya, will you make a tube,axle,bearing, wheel kit to sell?

Both wheels are attached to a single aluminum axle. The axle started out a piece of 1/8" ground 6061 and I machined each end down to .0935". The bearings I am using on this car (in the rear only) are .0937" I.D. rather than the .0469' that we currently use. Just spinning the rears by hand they spin so smooth! I have high hopes for this car but won't know till next week.

Brian,
I doubt this system would ever be for sale. If it works out, that would be great but the cost of machining all the parts would be way to much to offer to a racer at a decent cost. Shop rate where I work is about $100 an hour and I have5-6 hours machining on the rear end alone. I am sure the process could be refined to make the parts cheaper but just not something I see happening. If a racer wanted to pay the $$, I would do whatever they wanted.

I will keep you posted how it works anyway. More than anything, as a machinist, I just wanted to come up with something a little different than the norm. I love this hobby and love to try new things. I may fail miserably but I had a great time trying!

no way the tube assembly could be inserted into a hole drilled out in a pinewood body?

MAD SKILLS GOAT!!!

Thanks for all the comments guys. I will let you all know how it tests. Just trying new things to see what the next level is for this class.

Mario,
I hope your right about it being fast. Hopefully will see you next Friday.

Can't wait to see it run down the track Ian. That is an awesome car but I still have to say "Speed Metal" is my favorite in the looks category.

Goat you are a awesome builder. I love seeing your work.

 

[zeebzob]

I gotta tell all y'all....it's awesome being able to see Ian's work first hand. He has mad skills. I even get to see the "back to the ol' drawing board" cars that dont live up to his expectations. Can't wait to see this one on Friday Goat!

Goat Boy,

Interceptor is a unique car design! Yellow car body with Black and Red stripes are a good combination.

Ian, How did she test out?
