Avions Voisin Record 1927 1/8


Recommended Posts

I will try to explain my method to make louvers .
Warning! Cardiacs, purists, timorous, go your way, don't look at what will follow.

 

I don't use a press, I use my mini-mill (Sieg X2) as a press! Remember, 0.3mm annealed aluminum

is not very strong...

 

Overview:

Sorry, female imprint is not really clear...

And now, wish God help you!

 

Well, when I don't shoot my mini-mill, I'm cleaning the radiator cowl.

One side is _almost_ OK:

The other side...

Agreed... that's what I'm using on the Fiat, although annealing isn't really necessary at this thickness, imho.

I planned to use my mini bench drill as a press, but unfortunately, I can't find a way to stop any rotation tbh. ( it's not a built-in function...it's.very basic, so not unlike myself, lol).

 

Do you have any idea how I can lock the spindle??????

The easiest way would be not to lock the spindle but to add a flat surface to your probably selfmade tool. Then add a guide for that surface to your toolbase, so your tool has to lean against it. In the case of a selfmade louvre stamping tool a slot could also work as a guide.

 

@Dan, thank you again for the information!

Harvey, I don't agree... Un-annealed the metal keep always a bit of "memory" and its more difficult to form it.

I use a thermal cleaner, 600 degrees (Celsius), its perfect!

In a first life I don't had a mini-mill... But I had a bench drill. May way to block the spindle, with two metal bars bolted like this:

Hope this (bad) sketch help you...

Feel free to any question!

I use my Sieg X2 mill too, like Dan, but in a slightly different way. My tools are all custom made for one depth only - I can see the advantages in Dan's method, you can make a variety of louvres! If you look at the female tool, the distance between the slot and the end of the tool defines the spacing - the last pressing is pushed up against it to get it consistent. I also use a fence to line up the edge of the sheet. Oh, and the reason for the post - locking the spindle. I don't have a built in lock on my mill, so heres proof that Heath Robinson is alive and well and living in NZ...

I have difficulty knowing which are reference photos of the real car and which are the model. Superlative work.

I'm with you on that Duncan, I often have to do a double take to check what I'm really looking at.  This really is a model engineering masterclass!
