Years ago there were quite a few good prop makers in Australia.

Brad Waldron, Mick Dye, Bill Miller, all in Victoria, Barrie Bishton in NSW, and no doubt others that I cannot recall. All out of it, and Bill passed a while back.

Richard(?) Sweetapple. (never could find any contact details)

Ellis Walker (Perfectus Airscrew) - long gone.

Ian Henry was "the" prop maker in NZ for years.

Brent Thompson propellers (NZ) came on the scene - wow they were good, I had one. Now AeroPerformance.

Whoever makes the props for Jabiru to this day?

 

This could very well be old stale info, but:

Invincible Airscrews Pty Ltd - AMROBA - please let us know if you find they are still going.

 

I would love to hand make a propeller one day.

When ! .

Your ' home chopped prop ' is as good as you can make it , cover it in lightweight  glass and epoxy to get a super prop Finnish.

Website still offers Jabiru wooden propellers also, like they started with.

Somebody probably near Bundy is making them for Jabiru, like they always have.

The jabiru aircraft, I've seen in the UK have had a wooden props branded "GT" I don't know if this is the in house brand.

Possibly an alternative  to look at?

I am looking for a prop for a friend with a 912 gazelle. I don't think jab props will help.

It's unlikely it would match the change to geared engine and different cruise speed.  Suitable diameter might vary too. Wooden props don't like rain. Nev

Stainless insert for that leading edge.

It's all possible when DIY .

PYLON500 Made a composite prop , vacuum bagged , but " never again " said he .

Mine is clear finish glass covered, with some sort of polyurethane reinforced leading edge, maybe 8mm thick. 

 

"Depicted is a test propeller which was turned at 3300 rpm. A front end loader (JCB) slowly tipped 500kilograms of river sand (average grain size of 0.2mm up to 4mm) into the arc of the propeller. The end result was that 40% of the propeller was eroded. However only 3% of the urethane leading material was removed."

 

But coming from Sert Efrikah freight might be a problem.

Had a locally made wood prop (Newton) with that type of leading edge, went through a few light showers with no visible harm.

Only had the aircraft for 200 hours (prop was new when I got it) but the prop looked good after that amount of time.

Wood props do require care in installation and do tend to go out of balance with moisture changes.

 

Good practice is to always leave parked with blades horizontal (assuming 2 blade as most are) don't leave out in the blazing sun without some protection and take care not to crush the hub when installing or damage the finish as this lets moisture in

I've never seen a Jabiru with a Sensenich propeller. Since 2016 all new Jabs have been sold with their own design "Scimitar" composite prop made by Bolly from South Australia.

Speaking of wooden propellers - a tall tale, and true, of the Canadian north.

Just wondering - why the fixation on a wooden propeller??

 

There are so many very nice ground adjust props on the market. I wonder would not one of these fit your purpose & achieve a more optimised/durable & weather resistant, fan at the same time? 😈
