ANYONE HAVE ANY COOL 3D FILES TO MAKE PINEWOOD DERBY CARS ON CNC? I HAVE ONE I'M WORKING ON BUT WOULD LOVE TO FIND SOMETHING ELSE LIKE A CORVETTE, VIPER, FARRARI, LAMBO, ...ETC

[MegaMoog]

Just something plain, but fun!

These are not 3D, but they are Vcarve 2D, for use with a 90 degree .5" router bit- good for wedge-type cars. I made the dragon one and filled in the negative space with 2 part resin & it turned out pretty cool. Oh, and don't forget... the speed is in the axle prep!

My dad used to make some sick derby cars back when I was in the cubs. He makes custom woodwork for a living so he would really get into it. I'll post some pictures if I can find them.

Just havin some fun with home router.

Hey Moog, What software are you using?
That looks pretty cool. I have yet to take that next evolutionary step towards walking fully upright (3D). I'd like to get into it without spending a zillion dollars.
Thanks, Mike

I,m using Part Modeler to design and then use Edgecam to find features and create g code for Mach 3
on my cnc shark router which I built a vacuum table.:wave:

THIS IS WHAT I HAVE BEEN WORKING ON.
DESIGN IN PROE AND PROGRAMMED IN MASTERCAM.
I'LL POST COMPLETED PICS LATER

I have a few that Ive made over the years... pm me an email address and I will send you a couple if you like. Just let me know what format you would like them in.

Zoom Zoom Zoom!!!

I think they look nice, but what do you do with them?
My actual question is realy, whet the hell is a derby car ?

[MegaMoog]

Cub Scouts, Boy Scouts use them to race downhill. Track is approx. 25' long.
Different catagories best looking, fastest, most unusual etc.

supposed to be father son bonding type of thing.

Just for braggin rights also!

[Benny]

Ow ok. Well thats nice.
Never heard of it

[MegaMoog]

My son's didn't win first, nor second, nor third, but we had fun building them!
He did get BEST of SHOW!

Mine came in second in the parent's race where just about anything goes!

Now I'm workin on a wall plaque to show them off.

[MegaMoog]

Got the wall plaque done!

My son just loves it, and we had fun making it!

I was about 13-14 and I literally BUILT cars for the neighbor kid and my cousin. No CNC's, no cheated up mold machines, a kid building a car for a kid. THis was back in 1964. Mine were essentialy dupes of a Lotus Ford Indy car of the day hence I lay claim to the first REVERSED pinewood derby car ala what the designs shown are copies of .

Both cars kicked a$$ when it came to racing the eliminations One race, the elims and finals were all on one day. We won that so bad it was silly. Car was a bullet

The second deal was on TV with a kids show. Your ran elims on mon thru thurs, come back friday for the run off - winner got a trip to indy 500

THis deal was lame as they had a good lane and 2-3 bad ones, like the car would literally jump in the air after hitting a bump in the track. We stood a chance on any lane EXCEPT the two real bad ones. Darn if we didn't draw a bad one.

Even so we finished second - the car was a bullet and out ahead by a foot and pulling away until it hit the bump.

THe kids' deal was bad enough, I can't imagine what a "parents" race would involve.

CNC chassis, polyechnomorphic treatment of titanium zirconium unobtanium wheels. Don't forget the wind tunnel work.

IF a father dumped my kid's car on the floor, I"d perhaps fall into the table and take out the whole batch. Fair is fair, no?

THe fathers who pulled such crap scarred epople for life with their home boy stuff. THis and ohter posts above PROOVE IT. IF we got screwed with PD racing, we NEVER Forgot it. Thanks to the fine pillars of the community, rotten SOB's taht they were..
