Hand built racing car for a 1950 Great German Trophy. I suppose these are 16" VW wheels.

I love the rods, but are you sure they aren't going to break at hig rpm? I assume you are going to chamfer the holes on the rods to avoid stress risers which will lead to cracks? Great addition to the thread! keep the pix coming  |

Hi the stres on the rod is going thru the shoulder of the rod the rest is just fill up material lightning the rod like this make it do his job so good as posible just push the force from the combustion on the crank and when it comes up it wil not take as much weight with it les mass
so ill think it wil be stronger in a combo that suits it

It's about time you showed up here, Mark.  Are those stock VW rods? What does each rod weigh? |

The stock rods are 470 grams total, I have run the rods at over 6000 RPM on an 82 stroke and then REVVED IT!

So I was thinking about how I could reduce the rotating mass on my Erco's.I wanted to use the tapered washers that my wheels came with so that ruled out using 14mm Porsche alloy radius lugnuts, so I found some 12mm tapered alloy lugnuts. Not a huge saving I know (800g less than the lugnuts the wheels came with) but every little counts.  |

Now an even smaller (who said pathetic) saving,swapped rubber wheel valves for alloy ones,a massive 28g saving.  Not using dust caps waaaaaaay too heavy  |

Bruce,
Love all the holes! Is anything safe from the driller killer?
What is all this stuff going on/in?
Keep up the good work as it brightens up my day when I see such ridiculous behavior.

Join in! I think Phil said it earlier, VW over-designed a lot of the parts, so most parts can be lightened. My short term goal is to be able to build all these light bits into a Berg 5 and have the result weigh less than a stock 4 speed. 3-4 fork (bottom) 135 to 106g = 27% 5th fork (top) 117 to 92 = 21% |

lots of holes . how much kg will You save totall with this drilling? 50kg?. Good for me that I don't have to driil anything cuz I save 50kg in total weight of the car + driver in really easy way. I weigh 55kg so comparing to guys that weigh 80-90kg thats easy way to lighten weigh. BTW I'm not on the diet or have some kinda diesies But I like this thread. Any one made some tests with for example with drilled rods? they look really weak wht RPM's they'll survive? cheers Tom. |

What machinery do you use for bits like this? |

Bruce,
As Phil suggests I too love the quality of your work.
I can confess to my gear selector forks having holes in them as well, but not as many as yours (mine have been fine by the way).
I've also been rather extravagant with the framehorn bolts and made them in Titanium, but you will be pleased to hear, in the time honoured fashion they have blind holes in them and a taper to the head of the bolt much like yours. Sad but true!
I too have a 5 speed to build (the box I refer to above is a 4 speed) and interestingly I was thinking along the same lines that it would be good to get to the same weight as a stock 4 speed, so I hope you make it.
Keep up the good work, and keep the pictures coming.
Peter

Peter gave me another idea. Frame horn bolts, now 192g/pr. = 27% less Pulley bolt, now 58g. = 41% less |
