RE: [CAD_CAM_EDM_DRO] Re: Model Boat Propeller

hi Dave,

maybe you could get the basic dimensions from an off the shelf propellor and adapt it to suit your size requirements - of course this may not be the most efficient in the water but it would be your own design and manufacture.

I would be glad to help with the 3d modelling - STL file for milling

Hi Neville,

Sorry for the delayed response. My problem is that I know nothing about the
design of propellers. If I did I could draw it and then use software like
Meshcam or Millwizard to do the rest of the job. There is a package called
PropCad that does this design but the web site says I have to ask for a
quote - that sounds like bad nes for a hobbyist.

The simple solution is to buy a propeller - they are not that expensive -
but I am in the "make everything myself" mode on this project!

Dave.
