Home made propeller
Hi all,
Well that was hard!!!!
Getting the blades perfectly positioned took a bit of fiddling, Ron was correct of course about measuring the tips. There is 185mm between each tip to tip measurement. Angles of the blades match one another.
Ron, your home made sanding wheel picture inspired me to make a similar but smaller version to machine the inside top of blade hub welds, not much of an option if you want to do it fast. The under blade welds are relatively easy to blend in.
So thanks for the pic ron, really helpful.
Still took a decent amount of time to clean up the welds and blend them in as I ran a few welds over each other to build up some mass. I did v the blades where they weld to the hub.
I will sort the hub over the next little while, then ballance then polish.
Cheers,
Glenno
Thats awesome, how are you making the inside of the hub?
Fabulous work, and you left what looks like sufficient fillets.
How do you plan to balance it? I use a homemade spin rig with weights temporarily duct taped to labeled blades (like balancing a ceiling fan). A bit subjective, but it seems to work.

Home made propeller hub
Hi all,
I had 2 hours designated play time today so got some hub components fabricated. Need to press the components in and weld the main centre hub to the outer hub and then dowel the bushes in.
Having fun!
Cheers,
Glenno
Ps: Ron, how do you do your prototypes? They are a mission this way!
Careful with your alignment of so many pieces!

Hub alignment home made prop
G'day,
Hopefully all the pieces should self alighn as they push into each other.
I will spin the prop before welding the centre hub to outer hub for sure to check if it's all aligned.
Cheers,

Homemade propeller
G'day,
Hub is going well.
Aligning the main centre hub took a bit of tinkering to get correct. The bushes centre themselves.
Just need to dowel the bushes, ballance and polish.
Ps: I will take the anode off and add a nose cone on the outboard.
Cheers,
Glenno
Nice job mate
It sure is.
