Prop drive hub for a v1 DLE-111
 

In going over the engine after a somewhat forceful deadstick, I found cracks in the prop drive hub. I don't believe they came from the landing as it wasn't that bad. Pancaked the landing gear and broke the glue joints on the firewall. Didn't even break the prop. It was a blind landing so I was guessing when to flare. Anyway, I need to replace the prop drive hub and of course you can't by a V1 hub. So, I'm faced with a few options: find someone that has one they will sell, replace the entire bottom end so I can use the newer hub, sell the engine for scrap, or have a new hub custom manufactured.

Ideally, I'd like #1, so if anyone has a v1 hub they can sell me, please let me know. Otherwise, I'm considering having a new one made. If I go that route, I'd be curious to know if anyone else would want one. I've already done the design work and if I send it off to a professional house, a single one is about $200. If I increase the quantity the price, obviously, drops: qty 10 -- ~ $50 per, qty 25 -- ~$35 per. I'm also looking to see if I can find a local shop that can do it.

The part itself can be done almost entirely on a lathe. The exception being the slot for the woodruff key. Cutting a 70mill square slot down the length of a tapered bore is a bit more complex operation. I need to take some measurements to see if I can make it a bit deeper and get away with having the bottom of the slot rounded.

Anyway, I'd love thoughts and suggestions from the collective knowledge of the forum.

How many versions are there?

This is located in a shop in Austria, and it says it is for the "old version".

There are two versions of the prop drive hub: one that fits the v1 version of the motor and one that fits the v2 & v3 version.

Well, then that's the one.
I also came across some in a shop in Germany, but they are 60 euro's a piece...

If its just the prop hub your after I can make one for you. I see your out of the states and I dont know what sort of a hastle it is to get something in or out there but
If your interested give me a PM.
