Has anyone made a derby car to resemble the 928S4? If so, I am interested in pix.

Thanks

Andre Hedrick

Yep but it is an OB, just add the wing.
Pics to come later.

Pix pix pix, I need to make one this weekend for an employee event. For what I have in mind it sounds too difficult and I may end up making something else.

I'm sorry Andre, but that looks terrible.

Dave,
Don't be rippin' on Andre's Derby 928. It's a thing of beauty. Plus, no sunroof or rubstrips...
Ya know the trick to shaping up a block of pine for a derby? Bondo.
Makes 'em look real good... but no-so-fast.

Big Dave

I've seen some engineers around here use wider blocks so that the car isn't open-wheeled. Lotsa time and effort, but the results are near scale-models!

We usually use the traditional go-fast wedge shape. Ugly but fast. Last time the decoration consisted of black paint and YOU LOSE written across the front edge in red. Of course, the kids knocked the wheels and messed up the alignment, so he didn't defend his trophy.

It was hand sanded and whittled and following the rules exactly to the letter for BSA pine wood.

I am sorry but where is yours for comparison?



edit: did it in 3 days.

There was a great thread on OT not that long ago. Some of the dad's are SERIOUS. It has some good tips on how to make a fast car.

This is mine. I put about 20 min in it so far. Its amazing what you can do with the right tools. If I can get another piece of block I may make a wing for it :-). The final coating will be a nice shiney silver metallic powder coat finish with a clear coat.

Here's a few we've done...

#1..spent lots of time carving and sanding, including a spoiler. Performed terribly.
#2..built it in 2 hours in the classic wedge shape. Won 1st place.
#3.."open" derby @ work...no rules except weight limit..I made it motorized and remoted controlled. Finished 2nd to a car made in the engineering studio.
#4..tried the wedge shape again, but alignment was ruined before race.

We stopped trying to look good...and concentrate on fast instead.
