Description:
Design a propeller for pumping water. The propeller is molded plastic, 4.7" OD, 2.5" D hub, 5/8" bore,1.200" thick, 4 blades, with each blade .15" thick at the tip and .25" at the hub, max thicknes at 1/3 from leading edge, 10° pitch at the tip, 12° @ 3.76" D, 16° at the Hub, the top of the blade is flat and the angle to the horizontal is the angle(s) given.
Wants:
I am look at the ability to properly and smoothly provide the blade twisting profile
Ask for Sample:
We have numerous propellers to make
Software:

ok
blade sections are symmetric, or they follow some NACA profile?
when you say 10° pitch at the tip, 12° @ 3.76" D, 16° at the hub, what is the refference plane?
is the horizontal plane?, if so what is the angle between the horizontal plane and, let's say, the hub's axis
thanks

the propeller blade sections are .150" thick at the tip changing gradually to .200" at the hub. the thickest section is 1/3 from the leading edge. the leading and trailing profiles are arcs the arcs are tangent to each other at the tickest point.

hi there
i do not understand how the thickness is propagating along the blade
at the hub we have .25" thickness, isn't this the largest value?

also
what kind of profile would you like us to use?

thanks in advance for your answers

I have seen that common propellers have a section similar to NACA wings, where the curvature of the surface is defined, as well as radius of the attack border. I imagine they are specified in the procedure used for the calculation of the propeller. Please, inform if those sections will be provided.

Hollow ball that can open
I need a plastic prototype design in 3D. This object is a hollow ball (20mm in diameter, 1mm in thickness). The ball is composed of 2 parts (top and bottom piece). The top piece will slide into the bottom piece. On the top of the ball are small air vents (0.7mm) that form the shape of a circle. The bottom of the ball will have an opening (4mm diameter). There is a small arch inside the ball that sits at the base. The arch will extend from one end of the opening to the other. The arch will will be 1 mm in thickness. I have attached images I created with paint.

Oyster Cage
I need some oyster pots. The wire mesh will be 1/2" and the sides and center support will be made out of plywood. The mesh will be plastic coated steel from Riverdale Mills (1/2" center to center). Cage will be a cylinder with a 12" radius and a length of 4 feet. There will be a 3/4" rod passing through the center. Unlike other cages, one end will open for loading and unloading the oysters. See theoysterguy.com faq pdf for an idea of what I am looking for. Also see attached picture. I have come up with one idea for closing the ends, but any other ideas will be appreciated. The parts will be cut out of 1/4" plywood and cut out on a cnc machine (shopbot). Parts will then be coated in epoxy to make them waterproof. I want ease of assembly. Notches to align wire mesh. Longitudal arms should notch into center piece and have tabs to align outer ends. There should be hole in the sides to allow for waterflow and leverage when closing and opening one end.
Smart Bracelet - CAD Designer Contest for New Product
The e-touch The e-touch is a smart bracelet that has to be synced to your mobile device, when entering an event, meeting or club. When the connection between your mobile device and the e-touch is made, you can go ahead and 'e-Shake'. How does it work? When entering an event you’ll receive an e-Touch bracelet. By shaking hands with other people wearing an e-Touch, the bracelets connect and sync information trough your handshake, called the ”e-Shake”. The information received trough e-Shaking will be sent to an app, called Shake-on, on your mobile device which will store the information on your phone. Depending on your app settings/preferences the new information/friendship will be published on your Shake-on account (your personal page on the Shake-on social website).
