Thanks for all the follow up replies! I started experimenting with my fly cutter and my router...I think I can do them pretty easily that way. It'll just take time.

The 750 and 701 use the same size of dies... you won't find them as a stock off of the sehlf item!   You will have to have them custom made... as many builders do.   I made mine out od fir plywood and oak... very easy to do and they work great.  You are dealing with soft aluminum... you don't need more expensive ones unless you are building more then one plane.

The Sonex flanges are exactly the kind of die I'm looking for. Unfortunately, the hole sizes for the Zenith line and Sonex line are not the same. The CH750 takes the following die diameters: 51 mm, 65 mm, 95 mm and 115 mm. The Sonex dies are 3" (76.2 mm) and 4" (101.6 mm) . I've been looking for a setup like the Sonex plastic dies, except for the Zenith.

Hi all ... I'm new (very new!) here, and still waiting for my 750 plans, but regarding flanging dies I did come across these recently (offered by Sonex):

I'm not sure of the lightening hole sizes called for in your plans (or mine until they arrive!), but the above dies come in a set of two, 3" and 4".

 

There is a great vid on the EAA site showing how to scratch build a rib (6 part series). Part 5 shows the flanging dies in action:

Hope this helps!

Hey Gregory

 

You are working with soft aluminum and wood dies work very well... very forgiving.    I made all for 4 sizes out of scrap fir plywood!  See my album for Flanging Dies... A  $1000 is a lot unless you are  using for more then one aircraft!  All you need to make is a drill press and router/table... and a little  imagination a  creative mind.

Well, I have a router and a drill press, so the wood die should work. Although I'm intrugued by the other method too...thanks for all the tips & suggestions!

Hi Greg, here is an alternative to the dies. I made a roller type hole flanger for about $4.00 and it has worked great through out my project. This link shows a fancy one that I seen lately.

Here is the style that I made.

Here is a page showing a fellow making one.

Take a look at my pictures and look at some of my flanged holes, I think they turned out great for $4.00.

I hope this helps.

Gregory,

 

You do not need a lathe.  A drill press and a router.
