I think I spent half the video staring at your crotch.

Good ol' Clint,
when words fail.

 

[JMR Racing]

Great video I have to give it a try

 

[ngyoung]

o.k guys, I hope you got some balsa wood ready and a little time because it's game time. My son Willy filmed this for me because my normal camera woman is always feeding my newest son. This is how we build full balsa fender cars. Enjoy!

Really nice video. I liked that you didnt gloss over any of the steps to show pretty much the whole process. So what do you do with that nylon brush when you are done? Does mineral spirits clean off the CA glue?

 

[Crash Enburn]

I was wondering the same...

Hmm. Acetone. I heard you can use acetone to get it off your fingers; so it would probably work for this. Izzat the case, Bulldog?

 

[W8NONU]

Mineral spirits does nothing. Use Acetone.

 

[BulldogRacing]

I use a pair of scissors and cut the tips to bring forth new bristles. The brust cost 4 bucks new and I'll get about 20 uses out of it.

 

[The Iceman]

Thanks BullDog! Always nice see how other so it!!! Might try a few things different.

 

[microbrush]

Great job Bulldog! I usually wear a half face respirator while sanding balsa, applying and sanding CA glue but you are a tough guy BD!

I got a 3M mask for paint #8247PA1 and it made applying CA glue a LOT more tolerable. Thanks for the advise. Couldn't smell the fumes at all with it.

For CA fingers, go to your local hobby shop and buy a green bottle of BSI CA glue remover. Works wonders. Go figure.

I am trying to replicate Bulldog's process. Obviously not ready for prime time but I would welcome some advice. Below is a picture looking at right DFW with 3 degree bent axel. How close to the ground should the fenders go near the wheel? Should the fender mirror the cant of the wheel?

 

[Kinser Racing]

Mirror the cant. Use the circumference of the wheel in association with the fender to direct the air around them. The fender need not completely take the air off of the wheel but work together in unison with the wheel.

 

[BulldogRacing]

Great job! I would trim a small amount off the top and bottom of the fender to try and make it even with the wheel.

 

[Greatred]

Wilco. Thanks for the quick reply.

 

[HurriCrane Racing]

That looks much better than my first attempt! I just make sure the bottom of the fenders clear the track.

Great video Bulldog, I hope to do a fender car in the future.

Questions:

Why not use the curved end of the belt sander to do outside fender by going from center at the belt curve to the fender end on the belt flat?

Other than wieght, why not Bass wood or pine for fenders? I'd think they would be stronger.

Bottom of front fenders has a pretty big up sweep, is that to clear the tracks transition point (curve)?

I have a bunch of thoughts on the aerodynamics, but I'd have to illustrate them and as I'm not a real expert on the subject (some knowledge) I don't know how much effect they would have at this scale.

Anyway, love the video !

Why not use the curved end of the belt sander to do outside fender by going from center at the belt curve to the fender end on the belt flat?

I do that. Where ever the midpoint is between the front trailing fender and the rear fender, I use the sharp curveof the belt sander (pulley) to shave away the wood to the car chassis. From there, I can rotate the car on the pulley end of the sander using the straight part of the sander to remove the wood from the end of the fender to the mid point. Not sure if it makes sense, but it make nice curves and soft transitions from the front fender to the rear.

Other than wieght, why not Bass wood or pine for fenders?

The fenders don't need to be strong. they are just there to deflect air around the wheels. And need only be strong enough not to fall off. /images/boards/smilies/smile.gif

Yes I think I follow what you mean. Sound like he way I'd do it more or less .... Assuming I had a belt sander or someplace to plug it in.
